Anthropic files its S-1: Nasdaq ticker ANT, $16.3B half-year revenue, and a founders' 50.1% vote

Quotable summary

Anthropic, the company behind Claude, publicly filed a Form S-1 with the SEC on 26 October 2026 for an IPO of Class A common stock. It plans to list on the Nasdaq Global Select Market as “ANT.” Share count and price range are not set yet. The prospectus reports $16.3 billion of revenue in the six months to 30 June 2026, up from $1.2 billion a year earlier. It also shows an $80.7 billion net loss for the same period, and $72.4 billion of that is a non-cash change in fair value of convertible notes, derivatives and SAFEs. Then there’s the governance. A trust elects a board majority, a single founders’ share carries 50.1% of the general vote, and employees get their own voting class. Wall Street now has a lot of reading to do.

What changed

The governance stack, briefly

• Class A: the shares being sold. One vote each.
• Class T: held by the Long-Term Benefit Trust (LTBT), which can elect and remove the Class T directors. Those directors make up a majority of the board. No economic rights.
• Class F: a single share held by an LLC of the seven co-founders. It carries 50.1% of total voting power on general stockholder matters, including electing the non-Class-T directors. No economic rights.
• Class E: issued to employees (not co-founders). Votes only on limited matters, no economic rights.
• Class N: economically the same as Class A but non-voting, held mainly by strategic partners. Converts to Class A on sale to an unaffiliated party.

Why it matters

• The first real look at the books. Until today, Anthropic revenue figures were investor chatter and leaks. Now they are audited numbers in a filing with legal liability attached. That headline net loss looks scary, but most of it is accounting for the company’s rising valuation. The operating line is where the business shows up: $693M of loss on $16.3B of revenue.
• Control stays put. Public shareholders buy economics, not the steering wheel. Between the trust’s board majority and the founders’ 50.1% vote, outside holders will have very little say over strategy. That’s on purpose, and it fits the PBC “safety first” framing. It will also be the first thing governance-minded funds argue about.
• Safety is in the risk factors. The S-1 says that in June 2026 the U.S. Commerce Department imposed worldwide export restrictions on its Fable 5 and Mythos 5 models. Anthropic disabled them for all customers until the restrictions were lifted after a safeguards update. Regulatory risk on frontier models is now a disclosed business risk.
• Concentration to watch. No single customer tops 10%, but the top five make up about a quarter of revenue. The S-1 also warns that many top customers aren’t on long-term contracts and can cut spending at any time.

FAQ

Can I buy ANT shares today? No. The registration statement is not yet effective, and the share count and price range haven’t been set. Anthropic’s announcement says no shares can be sold until the SEC declares it effective.

Did Anthropic really lose $80.7 billion in six months? That’s the reported net loss. The S-1 says $72.4 billion of it came from changes in the fair value of convertible notes, derivative liabilities and SAFEs, mostly because those instruments rose in value as the company did. The operating loss for the period was $693 million.

Who controls the company after the IPO? Per the S-1, the Long-Term Benefit Trust elects a majority of the board through Class T stock. A co-founders’ LLC holds one Class F share worth 50.1% of the general vote, including the vote on the remaining directors. Class A buyers get one vote per share inside that structure.

What’s the valuation? The S-1 doesn’t set one yet. There’s no price range. Press reports have cited earlier private valuations, but GeekDad won’t print a number until the prospectus includes a range.
