Anthropic’s IPO: a doomsday warning with a $2 trillion price tag
Anthropic’s IPO prospectus, seen by Reuters, warns its AI could pose existential risks while asking investors for a valuation near $2 trillion and leaving its seven founders in control. Commentators find the warnings hard to square with the ask, read them as sincere and good for business at once, and split on whether the numbers justify the price.

Top threads
Anthropic’s warnings don’t square with what it’s asking for
5 showsThe Trump administration's position: if the CEOs believe it, they should slow down.
“this alarmism without solutions by some of the AI community, that's not leadership. … Well, then they should slow down. I mean, it's kind of like Hannibal Lecter, stop me before I kill again.”
The S-1 reads like a hostage note, not a prospectus.
“Anthropics said, okay, we lose billions. We need half a trillion dollars of infrastructure and our product might kill you anyway. Two trillion, please. … It feels like a hostage note with a cap table.”
Founders keep control while the filing warns about concentrated power.
“So to manage all the risk, Anthropic isn't asking for more oversight, it's asking for less. The filing asks investors to hand control of the company to its seven founders, even as it separately warns that concentrating power is one of the exact dangers AI poses to society.”
You can't call it a super weapon and expect normal-company treatment.
“you also can't have the people building this running around saying you're creating a super weapon and then be, and then expect to be treated. Like a normal company.”
The pitch asks for money to build what it warns about.
“like we need your money to build a technology that we're warning you about.”
The warnings can be sincere and still sell the stock
10 showsAnthropic’s warnings are external messaging and sincere belief at the same time.
“There's like external-facing, but like when you talk to these people internally, I think Anthropic is fairly sincere about their views about how AI works.”
The warnings long predate the IPO.
“there's a weirdness to this in that the things they are saying are not new. They've been earnestly saying these things for quite some time.”
A former insider vouches that Amodei means it.
“I think [Dario] has a lot of integrity.”
Warnings about super-powerful AI are speech aimed at investors first.
“When you're telling people that you have the super powerful machines, what you're speaking to first of all is to your investors.”
Safety warnings are partly regulatory capture that pulls the ladder up.
“I think some of it is, I'll call regulatory capture. You go to the top floor and then you pull the ladder up.”
Risk factors are standard disclosure, not a confession or a pitch.
“the risk factors are always really important and uh they're there to ensure that investors understand what could go wrong not what will go wrong.”
The danger is real; the catastrophism is overdone.
“I think OpenAI and Anthropic have a point. There is danger with AI getting into the wrong hands, but the extent of the catastrophism is quite crazy.”
The behaviors Anthropic discloses are real, a former SEC chair says.
“More and more, they're showing that they have some reasoning on how they deceive and how they jump out of guarded sandboxes. So this is a real challenge. I know the President calls it a hoax. I differ with the President on that.”
Labs censor employees on AI risk, so warnings aren't marketing or regulatory capture.
“If the AI companies were trying to push such narratives they would not be censoring their own employees on the same topics, and the employees most concerned would not constantly feel the need to resign in order to talk.”
Anthropic's safetyism in its prospectus is marketing or virtue signaling to employees.
“I think I view a lot of the Safetyism in their prospectus as at this point either marketing or virtue signaling to their own employees.”
Debate
Debate: Anthropic is worth $2 trillion.
The numbers don’t support it
5 showsAnthropic's $518B, 80% non-cancellable, is a leap of faith that any hiccup could make unpayable.
“It’s effectively taking us all on a leap of faith that it will grow enough to fulfill its promises. To pull it off, the company will need to keep surging amid stiffening competition, increased political risk, and tightening wallets. And any hiccup could have widespread consequences.”
Big TechnologyAt this price, the IPO buyer is the sucker.
“When you look around the poker table and wonder who the sucker is, it's you.”
The Prof G Pod – Scott Galloway · Start at 4:46Anthropic books gross cloud revenue, which flatters it next to OpenAI.
“I know you mentioned that anthropic investors are taking like a victory lap, but at the end of the day, I don't know if they really should be”
The Information's TITV · Start at 14:16Intelligence is becoming a commodity, and investors will notice.
“Once investors internalize the fact that intelligence, the main product Anthropic and OpenAI offer is a commodity, one wonders how they will feel about them as business.”
Tech Brew Ride Home · Start at 15:21The IPO is priced as if nothing can go wrong.
“Priced to perfection. It is priced to ultra perfection. There's absolutely nothing can go wrong.”

The growth does
3 showsThe spend is an early build-out, not recklessness.
“We're going to have 4 to 5 trillion being spent in next three to four years. But you're building the Vegas strip in 1955.”
Bloomberg Surveillance · Start at 11:54Menlo Ventures' position (an Anthropic investor): Anthropic is extremely undervalued because 2x growth on $50-100B run rate would justify 30x revenue.
“This has always been a mystery for me when people say these companies are overvalued because I think they're actually extremely undervalued.”
Corner Office Conversation · Start at 6:22Anthropic can grow into automating the $30T US economy as the high-end frontier lab.
“I think superintelligence, not investment advice, is a wonderful business to be in because there's a $30 trillion American economy out there to be automated and they're playing a lead role in automating it.”

The labs' own safety reports are turning into evidence against them.
“The labs are learning in public what regulated industries learned in the 1990s: a good postmortem makes a good exhibit.”
