$CBRS 👀 little bit of history … From Shivon Zilis’s July 18, 2017 email to Elon Musk $SPCX and Sam Teller:
Cerebras’s potential to decide the AGI race:
“Cerebras is a high beta experiment, they understand that, but think that if it succeeds it’s so game changing that if Google gets it, it’s game over re: race for AGI.”
The perceived technological lead:
“Reason is that even if we started on a billion core system today, it’s still 18 months behind and that’s enough to lose the battle.”
A potential merger or exclusive partnership:
“…think it’s prudent to figure out the right strategy to still merge or exclusively partner with Cerebras as well. They believe the combined entity, assuming OpenAI converts from being a non-profit, would be more valuable??”
Direct discussions with Andrew Feldman:
“Andrew Feldman reached out to them to discuss next steps. That meeting is planned for next week”
$CBRS Putting on my detective hat for a moment🕵️♂️😂
The original tweet comes down. SpaceX gets scrubbed from the invitation, and the event apparently disappears from SpaceX’s own calendar. Naturally, that makes everyone even more curious.
The original invitation explicitly named Cursor, SpaceXAI, and Cerebras, with people from all three teams invited. There’s clearly an overlapping social and professional circle here, along with coordination around the event.
An enthusiastic employee getting ahead of approved messaging is one perfectly plausible explanation. Another is that the invitation drew more attention to the relationship than anyone expected, and suddenly people were asking questions the companies weren’t ready to answer.
Seems clear that Cerebras and the SpaceX $SPCX team may be working together in ways we haven’t heard about publicly, and a friendly Halloween invitation accidentally put that relationship under a spotlight. Whoops. 😂 But why is that bad? I guess we'll see later.
The social overlap is clear, and it certainly makes me curious about where Cerebras’s ultrafast inference might fit into SpaceX’s plans. My hunch is there’s more happening professionally, and the public curiosity simply got ahead of their willingness to discuss it. 👀
$CBRS 🔥SpaceX's $SPCX and Cerebras' $CBRS Coming Out Party: here’s what we know, where the fit is, and why this connection has my attention👀👀
The public listing for “Cafe Compute: The Night Before RSI” names SpaceX SI and Cerebras as joint hosts of a Halloween event for people building with AI. It appears on SpaceX Super Intelligence’s own Luma calendar, putting both names together in front of the AI developer community.
That joint branding becomes more interesting when you look at the people and capital connecting the two companies. One of those connections runs through Gavin Baker, whose firm, Atreides Management, has committed substantial capital to both SpaceX $SPCX and Cerebras $CBRS.
Baker is a longstanding investor in Musk’s companies. He first invested in SpaceX in 2015 while at Fidelity, continued investing through Atreides Management, and subsequently backed xAI. The Wall Street Journal reported that an Atreides portfolio held approximately $2.5 billion in SpaceX stock as of April 2026. That is substantial capital and a relationship stretching back more than a decade.
Atreides also co-led Cerebras’ $1.1 billion Series G at an $8.1 billion valuation in September 2025. Its August 2026 ownership filing reported approximately 10.54 million Cerebras shares beneficially owned by the Atreides reporting group as of June 30.
That puts a longtime Musk backer with significant capital invested on both sides. The investor overlap adds another connection alongside the personnel relationships and technical possibilities.
The history between Cerebras and Musk’s circle also reaches back to 2017.
Internal OpenAI emails later disclosed through court filings in Musk v. Altman show discussions about acquiring Cerebras. A July 2017 update included negotiating merger terms and conducting further due diligence. In September, Ilya Sutskever wrote to Elon Musk and Sam Altman about a potential acquisition through Tesla $TSLA:
“In the event we decide to buy Cerebras, my strong sense is that it'll be done through Tesla.”
These emails became public through litigation years after the discussions. They establish how early Cerebras attracted serious interest within Musk’s circle.
Feldman added his own account at TechCrunch Disrupt on October 13, 2026.
Asked about those acquisition discussions, he said: “I had dinner with Elon and it’s quite a thing.”
He recalled Musk talking about getting to Mars and saving humanity while he was deciding between tiramisu and a cookie plate. Very Feldman. He explained that the founders believed in what they could build and felt the timing was wrong for a sale.
There is also a recent personnel connection. James Wang, previously Cerebras’ director of product marketing, is now a senior product growth manager at SpaceXAI. His official bio credits him with launching Cerebras Inference and the CS-3. SpaceXAI now has someone with direct experience bringing Cerebras’ technology to market.
On the developer side, Cerebras already supports using its inference service through Cursor’s custom API configuration. Developers can connect compatible Cerebras-hosted models to their coding workflow. That establishes a practical integration path.
The nearer-term opportunity I find most compelling is fast inference for Grok Bot, coding tools and AI agents.
Grok Bot operates a cloud computer with a browser, terminal and filesystem. A task can require repeated cycles of reasoning, taking an action, inspecting the result and deciding what to do next. My inference is straightforward: reducing model latency across those sequential steps could meaningfully shorten the overall task.
And the massive data centers Elon is building could absolutely accommodate hybrid Cerebras deployments. The potential architectural fit is obvious.
Cerebras explicitly designed CS-4 for mixed infrastructure. GPUs or other accelerators can handle prefill, processing the incoming prompt and preparing the model state. That state can then move to Cerebras for ultra-fast decode, generating the response. Cerebras’ published architecture supports splitting these jobs across complementary platforms, including configurations involving AMD $AMD Helios and Amazon’s $AMZN AWS Trainium.
At the scale Musk is building, combining enormous GPU capacity with dedicated Cerebras inference systems is a straightforward possibility to consider. GPU infrastructure could handle training and appropriate inference workloads, with Cerebras accelerating response generation for compatible models.
Grok Bot, coding agents and other interactive applications give that possibility a clear purpose: shortening the time between asking AI to do something and getting the job done.
The practical payoff would depend on model support, reasoning quality, context requirements, economics and time spent waiting for external tools. A deployment would require software integration, performance validation and a commercial agreement. The technical rationale for exploring a hybrid system is already there.
SpaceX has previously described an exclusive Nvidia $NVDA strategy for its compute buildout. Any future Cerebras announcement would need to explain how the arrangement fits into that strategy.
There is also a longer-term space opportunity, and Feldman has addressed it directly.
In his July Sourcery interview, he said, “we are really good for space.” His explanation centered on communication: getting many separate chips to talk to one another is difficult, and wafer-scale computing can reduce that burden.
That is an architectural argument from Cerebras’ CEO. He also gave a measured timeline, estimating that large production data centers in space were more than five years away. His comments describe a potential advantage that would still need to be engineered and demonstrated in an orbital system.
Musk’s recent SRAM comment adds another dimension worth thinking through.
On SpaceX’s October 20 earnings call, Adam Jonas asked about Terafab, semiconductor manufacturing equipment and improvements to the fabrication process. Musk described an SRAM test chip intended to validate the manufacturing line at the Austin research fab, with an internal target of May or June 2027.
The broader ambition was volume chip production at Gibbons Creek in late 2028, ultimately producing enormous quantities of AI chips. Musk emphasized that these were aggressive, uncertain targets. The SRAM chip represents an early manufacturing milestone within that roadmap.
That raises a more ambitious possibility: a future Cerebras relationship that extends into manufacturing and joint development.
Terafab’s stated mission includes producing chips for Earth and orbit, combining logic, memory and advanced packaging. Its published roadmap names AI5, AI6 and D3. Musk is pursuing the ability to manufacture the silicon needed for his expanding compute ambitions.
Cerebras brings a wafer-scale architecture, the associated engineering and software, and a CEO who has publicly explained why he sees potential in space computing.
One possible future arrangement would involve manufacturing Cerebras-designed wafers through an agreed partnership connected to Terafab, deploying Cerebras systems in terrestrial AI infrastructure, and eventually developing systems suitable for orbital use.
That is a hypothesis worth assigning some probability as the manufacturing plans develop.
There is an additional connection here: TSMC $TSM.
Cerebras’ filings identify TSMC as the manufacturer of its wafers and describe the company’s reliance on that relationship.
On its October 15 earnings call, TSMC publicly confirmed discussions with Terafab. CEO C.C. Wei said the company was exploring potential cooperation and emphasized that a participating fab would need to be operated by TSMC. Those discussions remained ongoing, with no final arrangement announced.
That gives us a concrete manufacturing connection to consider when assessing the longer-term possibilities. Cerebras already works with TSMC. TSMC is discussing potential cooperation with Terafab. SpaceX is building enormous compute infrastructure and pursuing orbital computing.
I can imagine a strategically coherent arrangement connecting those capabilities: Cerebras’ wafer-scale designs, qualified manufacturing capacity associated with Terafab, and SpaceX’s ability to deploy compute on Earth and launch infrastructure into orbit.
Making that happen would require explicit commercial and intellectual-property agreements, a qualified manufacturing process, suitable packaging and substantial additional engineering for orbital use. A Cerebras–Terafab manufacturing agreement remains unconfirmed in the sources I found.
The SRAM test chip belongs to the early development of Musk’s manufacturing operation. The broader roadmap gives us a legitimate reason to consider whether a future Cerebras relationship could reach into wafer production, capacity expansion or joint development.
This would be a multiyear possibility. The terrestrial hybrid-inference opportunity is already clear enough to evaluate on its own technical merits.
The Halloween party is the hook. The joint branding is what catches my attention.
Two major players are choosing to put their names together publicly. That looks deliberate to me. Add the historical acquisition discussions, Feldman’s personal contact with Musk, James Wang’s move, Gavin Baker’s substantial investments in both companies, and the potential technical fit, and there is a meaningful set of connections worth watching.
I think it’s reasonable to view that joint branding as a possible early signal of a broader collaboration. The event establishes cooperation around bringing the AI community together. The scope of any deeper commercial relationship remains an open question.
Hybrid inference. Faster agents. Potential manufacturing cooperation. Longer-term orbital compute. Substantial investor overlap.
I’m bullish as f*@# about the possibilities here!
Exciting times ahead. $CBRS $SPCX
$CBRS This guy gets it.👇 Exactly why it’s now my largest position. At this market cap, I see it as the purest AI play with the strongest growth potential.
$CBRS NO, I’m not bearish. I’m more bullish than EVER on Cerebras $CBRS. Nothing has changed in my long-term thesis. IMHO, this is a fantastic opportunity to enter or add.
This semiconductor selloff has been absolutely unhinged. My brokerage app now qualifies as an extreme sport! Weird things happen when the bond market needs a Xanax and Middle East diplomacy gets another season of The Apprentice. A certain someone whose name shall remain unmentioned has really outdone himself. Tremendous volatility. The best volatility. People are saying they’ve never seen volatility like it.
Put the valuation in perspective. Bloomberg Tech reported a $100B cash-and-stock acquisition approach from $ARM and SoftBank before the IPO. Cerebras rejected it. $NVDA Nvidia’s Groq licensing-and-talent deal reportedly totaled approximately $20B, for technology I consider inferior to Cerebras for ultrafast frontier inference.
Around $109, Cerebras is approximately a $26B market cap and $19B enterprise value, using its latest reported cash, investments, and debt. The entire operating business is being valued in the neighborhood of that Groq transaction. AWS also has warrants exercisable at $100. This valuation is hilarious to me. Apparently wafer-scale computing has been moved to the clearance aisle.
The bull thesis remains enormous: reasoning, coding agents, and real-time cybersecurity make fast inference increasingly valuable. Cerebras has a differentiated wafer-scale architecture, demonstrated frontier-model performance, and an expanding ecosystem across OpenAI, AWS, AMD, and CrowdStrike. Integration with Trainium and AMD hardware creates additional routes to deploy its ultrafast decoding technology.
The latest reported figures included $25.4B in remaining performance obligations, cloud revenue growth of 281%, more than 600MW live or contracted for delivery by the end of 2027, and plans to expand manufacturing capacity more than 10x during 2026. There is substantial execution ahead. The opportunity is extraordinary.
I’m tired of the recycled, confidently stupid Cerebras FUD. Read my thread if you want the full thesis. IMHO, this is the best name in AI, and this price is a total steal.
I’d happily buy more at these prices. I’m comfortable with my position size and very happy I’ve gotten my average WAY down. That being said, I’ve received enough character development from this chart to last several fiscal years.
Looking forward to the rebound whenever it comes. Hold tight, everyone. 😂
Chart is TrendSpider RSI ensemble: OVER OVER OVER SOLD.
CEREBRAS $CBRS: AI’S SPEED KING AND THE $1,000 BULL CASE FOR 2029–2030
My bull case for 2029–2030 come to roughly $800–1,000 per share. The financial model uses 2029, with growing customer evidence supporting the opportunity.
Start with capacity.
Cerebras’s SEC filing shows 750MW committed by OpenAI, with deployment expected during 2026–2028, plus an option for another 1.25GW by the end of 2030. That provides a contractual path to a potential 2GW. My 2029 scenario assumes an accelerated buildout and additional cloud customers bring average productive cloud capacity to 2GW during that year.
The infrastructure expansion is tangible. Cerebras announced a Finland facility scaling in phases to 165MW of contracted IT capacity, backed by seven-year service orders, with construction underway on the initial 50MW phase. This supports the expansion thesis. Achieving 2GW of productive average capacity in 2029 requires substantial execution.
On the August 12 Q2 earnings call, management said more than 600MW was live or contracted for delivery by the end of 2027, with an expansion pipeline measured in gigawatts. Manufacturing capacity was expected to increase more than 10× in 2026. Management also expects core revenue to more than triple in 2027 and continue growing at multiples in subsequent years. Those statements support the ramp thesis; $30–40B in 2029 is the bull-case projection.
Pricing?
I assume $15–20M of annual core revenue per MW, equivalent to $15–20B per GW.
There are real industry benchmarks behind that assumption. Nebius $NBIS disclosed four landmark deals at $20–25M of annual contract value per MW. CoreWeave $CRWV subsequently announced short contracts at approximately $40M/MW in annualized revenue. Those CoreWeave contracts run three to six months and reflect premium pricing.
These industry benchmarks involve different hardware and contract structures. My $15–20M of annual core revenue per MW remains an assumption Cerebras must achieve across its fleet, but it is realistic. The $25.4B backlog spans several years and includes certain pass-through amounts. Reaching $30–40B of annual core revenue in 2029 requires substantial additional bookings, timely capacity delivery and achievement of the modeled revenue yield. That being said, we are very early in the freshman year of the IPO and early in the roll out and scale up.
Market size gives this model context.
Cerebras’s IPO filings, citing Bloomberg Intelligence, estimate its addressable inference opportunity growing from approximately $66B in 2025 to $292B in 2029. My $30–40B revenue scenario equals approximately 10.3–13.7% of that 2029 forecast. At the $35B midpoint, the comparison is almost exactly 12%.
The specialized opportunity is substantial too. Public reporting of Citi $C analyst Atif Malik’s research puts fast inference at $130B in 2030. My revenue range equals approximately 23–31% of that later-year estimate, with the $35B midpoint at roughly 27%. These forecasts use different market definitions and include hardware or infrastructure alongside services. The 2030 date also matters when assessing the pace required to reach my 2029 target.
The physical footprint offers another perspective. McKinsey projects global inference demand of 71.5GW in 2029. My modeled 2GW fleet equals approximately 2.8% of that forecast. This is a nominal capacity comparison across all providers. Architecture, utilization and pricing determine the economic value of each MW and the resulting revenue share.
My thesis centers on Cerebras building a substantial, profitable position in fast inference. That specialty spans coding, agents, finance, security and scientific workloads, giving a focused architecture broad potential demand.
The customer evidence is growing too.
OpenAI identifies Jane Street, Podium, Basis and Rogo as early users of Cerebras-powered Ultrafast. Faster inference is already enabling more responsive development, voice and financial research workflows. These are customers of OpenAI’s service, powered by Cerebras capacity.
At Supernova on August 18, OpenAI’s Thibault Sottiaux said “we would love for Ultrafast to just be the default.” He acknowledged that this remained an ambition. That is a significant product aspiration from the customer already anchoring Cerebras’s capacity expansion.
SemiAnalysis (in their paywalled article we learned about during the “UltrafastGate” scandal that hit this weekend) reported on October 1 that Ultrafast service to Jane Street and a few other customers was being delivered at $200M/MW. That remains a reported outlier: I have not found independent confirmation, and the claim leaves the time period and Cerebras’s revenue share unspecified.
In his August 25, 2026 Dwarkesh Podcast interview, Dylan Patel separately discussed Jane Street capturing $300–500M/MW in economic value from AI, without documenting the calculation. My model uses the $15–20M annual core revenue per MW assumption above.
There are more disclosed commercial relationships worth including.
Cerebras signed cloud capacity agreements with Cognition and Lovable. It names Block $XYZ, Figma $FIG, AlphaSense and GSK $GSK as customers using fast inference for agentic workflows. Lovable’s agreement specifically includes dedicated Cerebras capacity for selected latency-sensitive workloads. On the Q2 call, Feldman disclosed six deals above $30M signed during the quarter.
The customer testimony helps explain why speed commands value. At Supernova, Figma’s AI research product lead Pavi Bhatter said “speed can become our strategy.” Cognition’s Silas Alberti described up to 4× faster completion of code-search-assisted tasks while preserving answer quality. These are examples of faster inference improving useful work.
General Compute announced a multi-year agreement to deploy Cerebras systems, initially targeting agentic coding. Gimlet Labs announced a Cerebras deployment for Gimlet Cloud. Callosum is integrating Cerebras silicon into its platform for heterogeneous agentic inference. These relationships expand the channels through which developers can access Cerebras performance. Their disclosed announcements provide no contract revenue figures.
Cerebras has also named IBM $IBM, Mistral, Notion and Mayo Clinic among organizations that have chosen its technology. Its SEC filing identifies G42 and Mohamed bin Zayed University of Artificial Intelligence as existing significant customers. These relationships broaden the established customer foundation.
The business is already producing revenue through both channels. Q2 core cloud and other services revenue grew 287% to $127.7M, while core hardware revenue reached $82.1M. CFO Bob Komin also disclosed several late-stage hardware opportunities representing hundreds of millions of dollars in the pipeline. Those prospective deals provide additional hardware upside as orders and revenue develop.
Cerebras earns revenue by selling systems and by selling access to its compute. Dedicated cloud contracts generally carry take-or-pay commitments, while on-demand customers pay for usage. My 2GW model assumes capacity monetized through Cerebras’s cloud services. External system sales and leases have separate economics. Systems deployed into Cerebras’s own cloud provide the infrastructure that earns service revenue, so that hardware investment and the resulting cloud revenue must be accounted for consistently.
AMD $AMD belongs in the thesis.
The announced joint architecture uses AMD Helios for high-throughput prefill and Cerebras for low-latency decode. The companies project up to 5× higher tokens per second per watt relative to a Cerebras-only configuration in their disclosed modeling. Cerebras’s Q2 update targeted production in Q4 2026.
At Supernova, AMD CTO Mark Papermaster said: “The users get better economics and low latency and that quick response.” He also described a partnership built over years, including AMD EPYC processors already used in Cerebras clusters. Arista Networks $ANET supports the networking layer, as Feldman explained at the event.
The commercial direction matters financially. Cerebras plans to buy and deploy AMD Helios systems. On the Q2 call, Feldman affirmed that Cerebras purchases the racks and receives the revenue from customers using the resulting cloud service. Discussing the joint offering, he added: “we have buyers for it already.” Buyer identities and order values were not disclosed. I found no announced AMD purchase commitment for Cerebras systems. The demonstrated opportunity is improved cloud economics and capacity to serve more customers.
Cybersecurity adds another growth opportunity.
CrowdStrike $CRWD and Cerebras have a confirmed strategic partnership. CrowdStrike will use Cerebras inference to help power Falcon AI Detection and Response. Cerebras’s Q2 update describes inline LLM security covering a large portion of enterprise traffic.
At Supernova, CrowdStrike VP of Engineering Keith Culley said fast inference enables “5x to 10x more inspection inside the same acceptable window of time.” Cerebras also highlighted Armis, now part of ServiceNow $NOW, reporting a code-security scan completed in roughly one-third the time, with more vulnerabilities found at lower cost. That comparison was presented by Cerebras; no contract value was disclosed.
My speculation is that broader deployment through CrowdStrike, larger security models and more agent activity could materially expand Cerebras compute demand. Gartner forecasts $244B in worldwide information-security spending for 2026.
CrowdStrike’s 2026 Global Threat Report found AI-enabled adversary activity increased 89% year over year, with average eCrime breakout time falling to 29 minutes and the fastest observed case taking just 27 seconds.
Inline security puts protection directly in the path of live enterprise AI traffic, making response time critical to keeping those workflows usable. Faster inference can support larger, smarter security models running continuously. That is the foundation for a potentially substantial, recurring inference business. Future deployment volumes and revenue remain undisclosed, and additional cybersecurity expansion beyond the modeled 2GW fleet remains unquantified upside.
Demand from national security customers also has a concrete foundation.
Sandia deployed four Cerebras CS-3 systems as the first part of a planned eight-node Kingfisher system, supporting the NNSA’s AI for Nuclear Deterrence strategy. Sandia, Lawrence Livermore and Los Alamos subsequently entered a third round of collaborative research with Cerebras through the Advanced Memory Technology program.
Cerebras also has a DOE memorandum of understanding supporting exploration of further AI and HPC collaboration under the Genesis Mission. Its Carahsoft partnership and inclusion in the Department of Defense’s Tradewinds Solutions Marketplace provide government procurement channels.
On the Q2 call, Feldman also described government technology partnerships involving stacked memory and integrated wafer-scale optical solutions, extending the relationship into future hardware development.
My speculation is that these existing relationships could expand into larger secure AI deployments, scientific agents, intelligence analysis and cyber defense. I leave that future expansion unquantified.
AWS and Meta add further upside.
Amazon’s AWS $AMZN has announced a hybrid inference architecture combining Trainium for prefill with Cerebras for decode, deployed inside AWS and accessed through Bedrock. Cerebras’s Q2 update targets availability in Q1 2027. That creates a distribution channel to enterprises already buying compute through AWS.
The commercial foundation is documented. Cerebras’s June 10-Q describes an initial multi-year AWS lease, options for future procurement and manufacturing capacity commitments. It explicitly says additional AWS purchases could make AWS a material percentage of revenue. My bull case includes Bedrock adoption translating into larger deployments and repeat orders as coding and agent workloads grow.
Feldman made a useful clarification on the Q2 call: “our $25 billion in RPO does not reflect any backlog of business from AWS or any other hyperscaler at this time.” That leaves hyperscaler expansion outside the backlog figure investors already know.
Meta $META also has an established connection. Its April 2025 LlamaCon announcement introduced experimental access to Cerebras-powered models through Llama API. That provides a technical precedent and an existing relationship for future expansion.
Meta’s newer Muse platform emphasizes agents, coding and reducing task latency, all areas where faster inference can matter. Broader Cerebras deployment across those workloads is a plausible upside scenario. Any Cerebras role in Muse remains speculative.
Alphabet’s Google $GOOGL deserves continued research.
Google named Cerebras as a supporter of its MLIR compiler infrastructure, and Cerebras now serves Google DeepMind’s Gemma 4 model. Those are documented technical connections. At Supernova, Cerebras CMO Julie Choi also mentioned demos from DeepMind, adding another ecosystem connection worth tracking.
On the Q2 call, management reported progress in discussions with other hyperscalers; an analyst also asked about Google and Microsoft $MSFT. I found no public Google purchase agreement or quantified Cerebras revenue commitment. I assign no Google revenue to this model.
These relationships give Cerebras additional paths to customer diversification and sustained demand into the 2030s.
The technology roadmap supports the economics too.
At Supernova, CTO Sean Lie described a CS-4 design with 50% fewer components, 60% more manufacturing automation and up to 3× faster system deployment. The roadmap targets twice the inference speed each year and solutions with up to 20× higher throughput by 2027. These are company claims and targets. Their financial significance is the potential to deliver more billable tokens per MW at lower cost as utilization and pricing evolve.
At Hot Chips 2026, Cerebras detailed CS-5, targeted for 2027, aiming for up to 5,000 output tokens per second per user on the largest frontier models. Its subsequent CS-6 roadmap adds 3D-stacked DRAM so more of each model can fit within each system, potentially reducing the infrastructure needed per workload and improving capital efficiency as those products are delivered.
My financial model:
2GW × $15–20B annual core revenue/GW = $30–40B revenue.
At 40% core operating margin = $12–16B core operating profit.
At 20× projected 2029 core operating profit = $240–320B enterprise value.
That multiple is equivalent to 8× projected 2029 core revenue.
Cerebras management has outlined a medium-to-long-term profitability target of approximately 40% core operating margin. Applying it in 2029 is part of my bull-case assumption. Core figures are non-GAAP and exclude stock-based compensation, customer-warrant amortization, data-center pass-through revenue and costs, and certain other items.
The Q2 call helps explain the margin thesis. Feldman said: “More tokens per system at lower cost means more revenue and more gross margin.” Komin reported core operating margin improving from negative 42% to negative 16% year over year, and described a path toward 60%+ core gross margin through higher pricing, improved throughput and a shift from higher-cost rented systems to owned capacity. Profitability remains a future milestone.
Capital efficiency matters just as much. Komin said Cerebras has “much lower net capital expenditure per megawatt” than most AI cloud providers. His explanation: Cerebras deploys its own hardware at bill-of-materials cost, while its largest customer reimburses a meaningful portion of data-center fit-out spending. That is management’s comparison, and it provides a concrete reason the company could retain more cash from its growth.
For valuation context, Nvidia $NVDA and Broadcom $AVGO currently trade around 28.5× and 39.8× trailing operating profit, measured using enterprise value. Their published forward P/E ratios are approximately 19.4× and 20.5×. Those figures provide context across different accounting measures and time periods.
My 20× assumption values Cerebras in 2029 using projected 2029 core operating profit, which includes equipment depreciation. At a 40% operating margin, that equals 8× revenue. The valuation requires sustained growth and cash generation after ongoing equipment and data-center investment. With an illustrative 20% tax rate and zero interest expense, 20× operating profit corresponds to approximately 25× earnings.
The midpoint is straightforward:
$35B revenue × 40% margin × 20 = $280B enterprise value.
Equivalently:
$35B revenue × 8 = $280B enterprise value.
My approximately $903 midpoint assumes 310M diluted shares and roughly zero net debt in 2029, with cash and liquid investments offsetting borrowings. The cloud buildout’s future funding mix remains uncertain. Holding enterprise value and share count constant, each $1B of net debt reduces equity value by approximately $3.23 per share.
A $250–300B equity value translates to $806–968 per share. At 360M diluted shares, it becomes $694–833. The share count and net-debt position are future assumptions that materially affect the result.
Cerebras ended June 2026 with approximately $7B of financial net cash, excluding restricted cash and operating lease liabilities. Management also describes lower net capital requirements per MW because it deploys its own hardware at bill-of-materials cost and receives reimbursement from its largest customer for a meaningful portion of data-center fit-out spending. Those advantages provide a plausible path to financing expansion through existing liquidity, customer funding and cash generated as profitability develops.
Customer usage within the 2GW cloud model gets counted once. AMD-enabled cloud usage follows that same rule. AWS leases and hardware purchases, along with systems sold to other operators, require separate revenue and margin assumptions as their economics become available.
Additional AWS, Meta, cybersecurity and government expansion remains unquantified upside here.
Capacity delivery, realized pricing, margins and dilution determine the outcome. The demand thesis centers on shorter time to decision across coding, agents, finance and security.
This is all of financial X right now. Totally useless discourse.
It's been amusing watching how little conviction the majority have had this year, changing their opinions based on whether a stock moves in one direction one day & the opposite direction the next, rather than having the ability to look a bit further out with some duration & consider where the ball could potentially be going next instead of simply where it is currently in play. And this isn't just in relation to the AI pockets of the market either.
The “people who don’t even own your stock showing up to gloat” phase is one of my near-bottom indicators. Most popular stocks are down 30–60%+, and some guy is accepting a Nobel Prize because yours went down too. Shorts still have enough confidence to give acceptance speeches, so there’s probably some suffering left. Feels like the later innings, though.
FWIW
$CBRS 💣 Short the hell out of it!! BURN IT DOWN! I want $90. After extensive due diligence, I’ve identified two serious structural problems: my average is too high and I don’t own enough shares.📉📉
Bears, please finish the job!
$CBRS around $126 means roughly a $30B basic market cap and $23B enterprise value, using the latest disclosed shares and approximately $7B of unrestricted cash and investments net of debt. That puts Cerebras’s operating business just $3B above the reported $20B Jensen committed to Groq’s technology and talent.
Remember: $NVDA Nvidia approached Cerebras about an acquisition and Cerebras declined. Asked about acquisition interest, Feldman’s response was perfect: “We don’t kiss and tell. We’re gentlemen.”
The evidence is substantial. Artificial Analysis currently measures Cerebras at approximately 1,737 tokens/sec versus Groq’s 474 on GPT-OSS-120B, roughly 3.7× faster. Cerebras also serves GPT-5.6 Sol across multiple wafers at up to 750 output tokens/sec, preserving the original weights, precision, context configuration, and reasoning settings. Add partnerships with AWS and AMD, $25.4B in remaining performance obligations, and a roadmap targeting further gains in speed and throughput.
To put a finer point on it: this comparison looks heavily skewed in Cerebras’s favor. A roughly 15% premium to the headline Groq package looks remarkably small given that combination of performance, partnerships, and potential.
The chart also flashes its strongest RSI oversold category. That adds a potential rebound setup to the valuation case. This looks like a buy zone to me. Mechanical selling, deleveraging, and further market weakness can still push it lower. Let's see next week, the whole $SMH is dumping hard.
The Series H price was approximately $89.02. A return there, using the same disclosed shares and balance sheet, would imply roughly $14.1B EV, almost 30% below the headline Groq package. Assuming demand and execution remain intact, that valuation would look silly as hell to me.
$CBRS around $126 means roughly a $30B basic market cap and $23B enterprise value, using the latest disclosed shares and approximately $7B of unrestricted cash and investments net of debt. That puts Cerebras’s operating business just $3B above the reported $20B Jensen committed to Groq’s technology and talent.

To put a finer point on it: this comparison looks heavily skewed in Cerebras’s favor. A roughly 15% premium to the headline Groq package looks remarkably small given that combination of performance, partnerships, and potential.
The chart also flashes its strongest RSI oversold category. That adds a potential rebound setup to the valuation case. This looks like a buy zone to me. Mechanical selling, deleveraging, and further market weakness can still push it lower. Let's see next week, the whole $SMH is dumping hard.
The Series H price was approximately $89.02. A return there, using the same disclosed shares and balance sheet, would imply roughly $14.1B EV, almost 30% below the headline Groq package. Assuming demand and execution remain intact, that valuation would look silly as hell to me.
$CBRS “44GB isn’t scalable"🤣🤣🤣 Sure buddy....
Apparently, an entire computing architecture can now be evaluated with one memory specification and a motorcycle meme saying “Bolting on farkle.”
The architecture, customer demand, financial disclosures, and product roadmap tell a much more interesting story.
Start with what those wafers actually do.
Cerebras keeps model weights in extremely fast SRAM alongside the processors using them. Larger models are divided across multiple wafers, with each wafer retaining its assigned layers and passing intermediate results to the next stage. Adding wafers expands the system’s aggregate memory while preserving local access to each portion of the model. Cerebras documented this approach when it launched inference in 2024.
The model-by-model arithmetic makes the scale tangible.
Llama 3.1 70B: At 16-bit precision, its weights require approximately 140GB. Cerebras disclosed serving it on as few as four CS-3 systems, providing 176GB of aggregate SRAM. That is a documented deployment configuration.
Llama 3.1 405B: Its 16-bit weights require approximately 810GB, implying a calculated minimum of 19 wafers for weight storage alone. Cerebras reported serving the model at 969 output tokens per second with a 1,000-token prompt. The benchmark’s actual wafer count was undisclosed.
Kimi K2.6: Approximately one trillion parameters stored at its original 4-bit precision imply roughly 500GB of weights, or a calculated minimum of 12 wafers for weight storage alone. Cerebras reports 981 output tokens per second, measured by Artificial Analysis through a private endpoint, using 16-bit computation and speculative decoding. The actual installation count was undisclosed.
The 19- and 12-wafer figures are storage calculations. Real deployments also need working memory, attention caches, and capacity for efficient model placement. Precision matters enormously: a hypothetical trillion-parameter model stored at 16-bit would require approximately 2TB for weights, implying 46 wafers before those additional requirements.
GPT-5.6 Sol takes that architecture to a leading frontier model. OpenAI previewed it on Cerebras at up to 750 output tokens per second. Cerebras confirms multiwafer execution while preserving the standard model’s architecture, weights, precision, context configuration, and reasoning settings.
For perspective, outside analyst Bleys Goodson estimates Sol spans 70–100 wafers, which would provide approximately 3.1–4.4TB of aggregate SRAM. The exact count remains unconfirmed. The published 750-token-per-second performance already includes coordination across the multiwafer installation. That is the demonstrated capability relevant to the scaling argument.
Customers are already asking for more.
CTO Sean Lie told Latent Space that @cerebras was “sold out of everything that we’re building,” with substantial capacity allocated to OpenAI.
At TechCrunch Disrupt, @andrewdfeldman identified insufficient Cerebras data-center capacity as a key reason OpenAI used NVIDIA GPUs to expand services for its next-generation model. OpenAI has a lot of the capacity reserved for internal use. His explanation places physical deployment capacity squarely in the growth equation.
For the bull thesis, that makes bringing additional capacity online the most valuable commercial opportunity. It also makes every improvement in the productivity of existing capacity more consequential.
This is where AWS and AMD become economically important.
Inference has two major stages: prefill, which processes the incoming prompt, and decode, which generates the response. The announced partnerships assign prompt processing to AWS Trainium or AMD Helios, allowing Cerebras to concentrate on fast generation. Each part of the installation performs work suited to its strengths.
The objective is easy to understand: serve more customers at the response speed they value, and earn more from the hardware already deployed.
Cerebras reports 5× greater throughput in early tests using the same number of its systems, with token-generation speed preserved. Additional prefill hardware enables that improvement. The wafer fleet can support substantially more total output while maintaining the speed experienced by each user.
AMD separately disclosed up to 5× greater tokens per second per watt for Helios plus Cerebras compared with Cerebras alone. Its footnote identifies joint modeling by AMD Performance Labs and Cerebras using Kimi 2.6 1T at comparable responsiveness. That supports the proposed combined system’s energy-efficiency rationale.
Feldman addressed the financial implications directly on the Q2 call. Cerebras purchases the Helios racks, installs them in its cloud, and receives the service revenue. He explained that higher throughput increases revenue opportunity per system and said, “That means tokens cost less, tokens use less power,” alongside an expectation of improved margins.
That is the economic purpose of the integration: more revenue-generating work from the wafer investment, supported by a more efficient division of labor. The additional hardware earns its place through the output it enables. Equipment, networking, power, and utilization determine the realized savings.
The financial disclosures give that opportunity substance.
In Q2 2026, core cloud-and-other-services revenue reached $127.7 million, growing 287% year over year. Core cloud gross margin increased from 26.0% to 41.8%, with the 10-Q attributing the improvement to higher pricing and greater utilization. GAAP cloud gross margin was 19.5%.
Those results show how pricing and productive use of installed capacity already influence the business. They describe the existing cloud operation, ahead of the planned heterogeneous production deployments.
The June 10-Q also reported $25.4 billion in remaining contracted revenue obligations, with a significant portion attributable to OpenAI and certain data-center pass-through charges included. Dedicated-capacity contracts are generally take-or-pay, providing payment commitments regardless of customer utilization. That gives Cerebras contractual support for its expansion.
The capital model deserves attention as well. Its CFO explained that Cerebras deploys its own hardware at its bill-of-materials cost and receives reimbursement from its largest customer for a meaningful portion of data-center fit-out spending. Management identifies both arrangements as advantages in net capital expenditure per megawatt.
The roadmap extends the opportunity across several generations.
Supernova and Hot Chips outlined a coherent progression: connect wafers more efficiently, generate more fast output within the power budget, and increase the memory available in each system.
CS-4 improves the rack. Three wafers provide 132GB of aggregate SRAM. Per-wafer memory bandwidth and external I/O bandwidth double, and direct connections link wafers within and across racks with latency as low as two microseconds. The compute backpack has 50% fewer components. Cerebras claims up to 10× greater throughput per watt versus CS-3, depending on workload and configuration. These changes address communication, manufacturing, deployment, and infrastructure productivity together.
CS-5 advances the wafer. Targeted for 2027, it combines the Nexus platform with a new wafer generation. Targets include 5,000 output tokens per second per user on frontier models, up to 10,000 on selected smaller open models, and 3 million tokens per second per megawatt. The ambition is substantially more fast intelligence from the available data-center power.
CS-6 expands memory vertically. Its planned integration of 3D-stacked DRAM with wafer-scale SRAM and compute would allow more model data to reside in each system. Cerebras targets an approximately tenfold smaller system footprint for ultrafast inference. This directly addresses the amount of infrastructure needed to serve large models.
Management also targets more than 20× throughput improvement through the end of 2027 across its development program. CS-5, CS-6, and these longer-term performance figures remain targets requiring production validation. Their different baselines call for separate evaluation.
The execution test is concrete. Long contexts and simultaneous users require attention-cache memory. Prefill and decode capacity must stay balanced. The complete installation must earn an attractive return after equipment and operating costs. A precise public calculation of realized total-cost savings for the new combined systems remains outstanding.
Why I remain bullish
My thesis is that the value of intelligence increasingly depends on how quickly it can finish useful work.
An agent reasons, writes code, calls tools, checks results, and starts the next step. Faster inference can shorten the wait throughout that sequence. As those workflows become more capable and economically valuable, I expect demand to grow for infrastructure that delivers frontier intelligence at exceptional speed.
Cerebras’s opportunity brings together demonstrated multiwafer inference, substantial contracted demand, specialized partner hardware, and a roadmap aimed at improving the productivity of each successive installation.
More useful work per wafer. More high-value output within the power budget. More customers served at the speed their applications require.
My $CBRS bull thesis is that Cerebras can turn those technical advantages into expanding earnings power as fast, autonomous AI becomes an essential part of the economy.
$ASTS 👀 founder of Boost Mobile says AST SpaceMobile is a buy
I think the AST SpaceMobile stock price at a $40 low is a safe time to buy for me. So at these levels, I am a buyer it still has room to fall but taking a punt now seems a good bet . The market has finally pushed the stock down to a level that I believe better reflects the company’s underlying value .
A story as old as time. Shakeouts and blowups are when the professionals step in and put their dry powder to work.
Yesterday, those of us addicted to FinX and stocks were glued to our screens, feeling like the world was ending. About 99% of the world was having a perfectly normal day, completely oblivious to the carnage.
Stay safe. Keep some perspective. No leverage. Everything will be okay. If you blew up your account, that last part comes with some fine print.
No, we haven’t liquidated and no, we have no plans to do so.
Selling at important seasonality lows…just as hedge funds have exited…is not how we’ve outperformed the market in 19/22 years.
This decline is about one thing IMO; a resumption of kinetic action with Iran, because it looks likely.
And that means this selling pressure is taking place in advance of it. To that I say “when missiles fly, stocks are a buy”.
We’re primary trend followers and we use drawdowns to add to core positions. We’ll soon be doing that again.
