Anthropic IPO filing: $800bn compute bill, founders keep control (opens the source in a new tab)

- Anthropic's S-1 sets up a Nasdaq listing under the ticker ANT as soon as next month. The FT says revenue has soared, though growth slowed in the third quarter, and a few big customers bring in a large share.
- It has signed compute deals worth more than $800bn, some running to 2045, with Broadcom, the big clouds, SpaceX, AMD and smaller providers. The founders call the approach bold but sane.
- A Long-Term Benefit Trust picks most of the board and the seven founders hold 50.1% of the vote. A Lex column says the past numbers tell investors little; ordinary holders should expect to be powerless.
- $800bn+
- compute commitments
- 50.1%
- founders' share of the vote
Why it matters The biggest AI listing yet asks public investors to fund a frontier lab while giving them almost no say. How it prices will set the bar for every lab that follows.
Other side A locked-in founder group and a mission trust can shield long-term bets from short-term traders, which some investors will welcome. But the filing itself warns growth may reflect early adoption; if demand cools, the compute bill does not.
