I’ve gotta say, I’m unbelievably proud of the fellas on the acquisition marketing team (led by @JefeHammers) and the b2c product team (led by @NickelandDiming) at @ProphetX.
Cracking top 100 on the App Store when half of our company, still at a modest size of ~60, is focused on our B2B push with a sliver of the marketing budget of our competitors is a huge accomplishment.
No famous athlete ambassadors. No actresses prancing around naked in an ad. We are the Oakland Athletics.
Pumped for where this company can go!!
Expect this to get to 10x by year end with all of the product improvements we have coming in this quarter
Live college football trading on ProphetX is up 3.8x since Week 1.
In Week 1, 16% of our college football volume traded in-game. Last week it was 29%.
That's not a coincidence. In-play traders go where the prices are tightest and the fees are lowest.
If you trade in-game, Week 8 starts today. Come trade it on @ProphetX.
I could talk the ins and out of PMs all day long. Thanks for having me on @UnabatedSports @capjack2000 🤝
Are prediction markets a place where rec bettors are lambs to the slaughter?
@DeanSisun of @ProphetX doesn't think so.
@capjack2000 sat down with Sisun, @a_kane47 of @sporttrade_app, @irishro of @TeamMatchbook, @BigBuckHunterrr of @magtradingHQ and @samschwartz71 of The PM Pulse for an in-depth conversation about how they got to where they are, what the journey to building prediction markets has been like, and where we're headed.
Pretty interesting breakdown on price discovery. Naturally the 4 main exchanges lead the pack.
But if you listen to the sportsbook rhetoric, we’re all criminals looking to steal your money. Which totally makes sense after this analysis.
Louder for the people in the back !!
Call it gambling, call it trading, whatever. The real question is who treats consumers better, and if "preying on vulnerable New Yorkers" is the concern, you might want to start with the sportsbooks.
Kalshi and Polymarket blazed the trail, and everyone who followed owes them for it. But it appears to the public that both companies haven't had enough adults in the room, and their hiccups have handed regulators and opponents exactly the stories they want.
@ProphetX and @Novig show what it looks like done right. Built by bettors, for bettors. They both tried the state by state route first. That model makes it impossible to scale, and the unit economics would suffocate any startup, which is probably why they went the CFTC route.
This is less about consumer protection than politics, lobbying, tax dollars, and protecting the old guard from innovative companies that are actually better for the people using them.
A couple of my friends sent me this post. This is peak lazy reporting and click-baity material from mainstream media who misunderstands sports trading.
It’s also a great example of why prediction markets are king.
$120,000 of handle per year at an assumed 10% loss rate = $12,000 per year = $1,000 per month = ~$33 per day. I’ve bought poke bowls in Manhattan that are more expensive.
Prediction market users on average win more and lose less due to the market compressing prices. The collective ROI of our frontend users is ~-1%, which would be $100 per month or ~$3 per day at the same handle rate.
Your daily iced coffee is 2x more expensive than that.
A 29-year-old pest control salesman says he bets on sports every day, wagering between $80,000 and $120,000 a year — as much as or more than his $97,000 salary.
He tells @JimAxelrod he sometimes puts an entire paycheck on his bets. cbsnews.com/news/sports-bett…

Grouping a two-sided exchange with a one-sided sportsbook model does not make sense. We originally went a state by state gaming regulated route and were forced to squeeze our product into previously written sportsbook regulations. This misalignment physically drove us out of the space.
Sports contracts deserve to be regulated by the CFTC, which results in a far better product for the end consumer. Plain and simple.
Our CEO @DeanSisun submitted a comment letter today to the CFTC urging to preserve two-sided exchanges in Sports Prediction Markets built to benefit consumers.

If, on an exchange, you post a resting order at +102 on a traditional -110/-110 game you will
a) virtually always get filled and
b) virtually never match with a professional MM
The attempts to try to demonize “peer-to-peer” are woefully ignorant.
Another big announcement calls for another blog post. I am so proud of this team and everything we have accomplished - and this $35M raise is direct validation of our progress.
Job is nowhere near finished. Sports deserve to be a global asset class, and they're well on their way to being one.
Onwards 🚀

$35M raised. 📈
Backed by Parlay Capital, Data Point Capital, and a stacked group of investors who believe in the future of ProphetX.
What we’re building next is going to change the game. Stay tuned. prophetx.cc/mrk17u
In a new interview with @CapitolAccount , ProphetX CEO @DeanSisun outlines our long-term vision:
Modernizing how sports outcomes are traded through a regulated, exchange-based model built specifically for the complexities of sports. prophetx.cc/A9pXvv

Big news announcement from @PlayProphetX calls for a first ever Substack post.
Prediction market leaders in this space are not pushing the proper agenda when it comes to sports. Our message is black and white - prediction markets bring a fair, transparent environment to what is currently an unfair, opaque space with sportsbooks. Simple as that.
Sportsbooks are criminals hiding in plain sight. Anyone who wants a better experience should be rooting against them. We will continue battling them.

🚨 ProphetX. Approved. Nationwide.
Stay tuned for more updates as we bring our product to the masses next week.
JUST IN: We have obtained @CFTC approval to operate America's first federally regulated sports-native prediction market!
Dean Sisun retweeted
This is a federal powers matter.
You don’t have to like “prediction markets” to understand this.
States make a lot of revenue from licensed gambling, and the lobby funnels that to senators and governors.
That tax is basically a license that lets them be the “house” and make money when you lose.
Congress’ passed an Act in 2010 called “Dodd-Frank” prior to that “binary swaps” were primarily used on commodities, so farmers could hedge crop yields and things like that.
Dodd-Frank expanded the definition of a swap to include *any*, and clarified that the CFTC had authority subjectively over event contracts and that only war, assassination, gaming, and illegal acts were expressly banned.
That bill was voted for by many current members of Congress who are arguing against it, such as Bernie Sanders, Amy Klobuchar, Adam Schiff, Chuck Schumer and in 2018 even Elizabeth Warren fought against the bill to rollback Dodd-Frank.
Now state governors want to pretend these things exist “outside the law”
And Senators like Adam Schiff who take money from the gambling lobby argue it’s a “states rights issue”
But it’s not.
The Constitution has a “Supremacy Clause”
States can regulate things that the federal government has not, and they can retain their policing powers, and opt out of enforcement of things at the state level (like they did in many places with marijuana)
But what they cannot do is over rule or replace a federal law.
If an Act of Congress gave authority to the CFTC - that’s it. The CFTC wins.
Only a law in Congress can change that.
No state governor, no state attorney general, and certainly no gambling commission can change that.
It is a literal constitutional matter.
The CFTC requires these exchanges to have fair access for party to party trading and regulate just like major commodities exchanges.
That enforcement is stricter than state alternatives.
So why do states care?
Tax revenue.
Federally regulated exchanges don’t pay a *state* tax.
So even if you’re in the camp that thinks prediction markets shouldn’t be a thing, you have to understand the perverse incentives here.
Multiple states, their governors, attorney generals and senators are trying to ignore the constitution, and sell out on protecting their citizens, to protect manipulative revenue from the gambling industry.
And they know they can do it, because they can sell you a boogeyman story because people are sick of gambling.
But somehow instead of talking about banning DraftKings, they’ve convinced you, they can ignore the constitution to go after anything they find “distasteful”
It’s all about political points with populists and tax revenue from gambling.
And no matter where you sit on that debate it’s important to see through the bs.
There’s no legal difference between predictive markets and sports betting markets…In the end, it’s a bet.
These are rogue actors who are out there operating outside the law, and they need to be brought back within the law. They said there are safeguards in place. What we're showing is there are no safeguards in place. States must continue to act to protect their rights and the rights of their citizens.
