We’re committing a portion of Anthropic’s shares to the Anthropic Public Benefit Fund, a new wholly owned entity dedicated entirely to the public benefit.
It will start off with 5% of our shares. For every 50% increase in the company’s value over a set baseline, we can contribute up to an extra 2%, subject to our board’s discretion.
In total, this means that roughly 20% of Anthropic’s shares are committed to the public good. Our co-founders have already pledged to donate 80% of their equity, and around half our employees are donating a portion of their equity as part of a donation matching program we’ve run since our founding.
In the post below, we share more details about our new fund.

We Must Pace the Frontier: I’ve written a new essay on why the AI industry should slow down, with a three-part plan for doing so.
Anthropic is unilaterally committing to the first of these steps. We’ll provide third-party evaluators with permanent, employee-level access to our systems, so that they can verify adherence to our safety measures, report on incidents, and assess models’ alignment during training.

Anthropic’s new threat report is absolutely insane.
They claim:
-Alibaba extracted 151M+ Claude exchanges to help train Qwen
-Kimi secretly routed some users to Claude without them knowing
-DeepSeek apparently did the same
-A weapons group used multiple Claude instances as an engineering team, test-fired a guided rocket, FAILED, then went back to Claude to figure out what went wrong
What the fuck did I just read 😭
We're publishing our most detailed threat intelligence report to date.
It covers how people tried to misuse Claude—for cyberattacks, influence operations, surveillance, biology, and building weapons—and how we found and stopped them.
We disrupted every operation in the report, and used the lessons from them to strengthen our safeguards. Where appropriate, we also shared what we found with authorities and other AI companies.
These cases are not typical: we’re highlighting some of the most sophisticated misuse we’ve seen. But they’re especially important to discuss, because they show us where AI misuse is headed, where our safeguards work, and where they need to improve.
We’re publishing this report so others can spot the same activity on their own platforms, and so we can give the public a clearer view of how emerging threats develop.

PSA: Many sunscreens are AWFUL. If you wear sunscreen daily (and you should!), double check that it protects against UVA *and* UVB.
SPF is UVB protection, but UVA is what causes aging (and both contribute to cancer). Look for “PA++++”.
Many have been burned by this!

Our internal data shows Claude is accelerating AI development—a possible path to recursive self-improvement, or AI autonomously building a more capable successor.
It’s happening faster than we thought, and the implications deserve greater attention. anthropic.com/institute/recu…
The faker makes a fool of the expert. So who is the faker, and who is the expert?
What happens when you post a real Monet and say it’s AI? The coolest art social experiment I’ve seen in a while. Thank you @SHL0MS

“Our lawyers have studied the designation and have concluded that Anthropic products, including Claude, can remain available to our customers — other than the Department of War."

For those wondering how mass domestic surveillance could be consistent with "all lawful use" of AI models, I recommend a declassified report from the ODNI on just how much can be done with commercially available data (CAI): "...to identify ever person who attended a protest"
I think it's reasonable to believe that large companies operating under the same incentives will converge to the same behavior in the end. However,

Agree with him or not, the (oddly popular on here!) take that Dario Amodei is some kind of bumbling Silicon Valley naïf who couldn't get a deal with the Pentagon done because he doesn't understand politics seems entirely wrong.
His favorite book is "The Making of the Atomic Bomb." He used to buy copies for new Anthropic employees. (There's still a copy prominently displayed in the Anthropic library.) He fully expected -- back when it was a crazy thing to expect! -- that AI would become as important as nuclear weapons, and that the people who built it, like the scientists of the Manhattan Project, would face pressure from governments to use their technology in ways they found immoral or dangerous.
I am sure this all could have been handled differently, but none of this is a surprise to anyone who knows anything about the relevant people.
One thing I love about Anthropic is that our hiring process often includes a disclaimer that we will absolutely do something that zeros our equity if we think it's the best thing for the world.
We are not anywhere close to that here—DOW can only block us from DOW contracts—but
