Anthropic, the company behind Claude, has publicly filed its S-1 registration statement with the SEC, putting its long-awaited IPO on the calendar. The company plans to list Class A common stock on the Nasdaq Global Select Market under the symbol “ANT.”
The filing is the first time everyday investors can read Anthropic’s real numbers, from revenue to risks. The share count and price range are still blank, so the final valuation is not set.
What Anthropic’s IPO Filing Says
The preliminary prospectus covers shares sold by Anthropic and by existing stockholders. Anthropic will not receive money from the shares those selling stockholders offer. The company says the securities cannot be sold until the registration statement becomes effective.
Goldman Sachs and Morgan Stanley lead a long roster of underwriters that also includes J.P. Morgan, Citigroup and Barclays. Engadget reports the stock could debut in mid-November at a valuation near $2 trillion, though Anthropic itself says pricing has not been determined.
- Exchange and ticker: Nasdaq Global Select Market, “ANT”
- Share count and price range: not yet determined
- Offering: shares from Anthropic and selling stockholders
- Status: registration filed, not yet effective
Anthropic IPO Financials at a Glance
The numbers are huge on both sides of the ledger. Revenue is growing at a pace few companies have ever matched, but losses and spending commitments are growing too.
| Measure | What the filing shows |
|---|---|
| 2025 revenue | $4.6 billion |
| 2025 net loss | About $42 billion |
| Revenue, Jan-Jun 2026 | $16.3 billion |
| Net loss, Jan-Jun 2026 | $80.7 billion, much of it tied to an accounting adjustment |
| Cash and equivalents (June 30) | $112.4 billion |
| Capital raised so far | $141.1 billion |
| Compute commitments | At least $265.6 billion |
Revenue for the three months ended June 30 grew 1,368% from a year earlier, while compute and infrastructure costs grew 300%. Anthropic told investors in mid-October that third-quarter revenue reached $16.8 billion. It also warned that its growth rate may fluctuate and decline over time.
Who Controls Anthropic After the IPO
Anthropic is a Delaware public benefit corporation, and its structure is unusual. A five-member Long-Term Benefit Trust can elect a majority of the board through a special class of Class T stock. Because of that, Anthropic counts as a controlled company under Nasdaq rules.
Just before the offering closes, a single Class F share will go to an LLC owned by the seven co-founders. That one share carries 50.1% of total voting power. Class T, Class F and Class E shares carry no economic rights, so they shape control rather than payouts.
The company also put 5% of its fully diluted shares into a public benefit fund. Each co-founder has pledged to give 80% of personal Anthropic equity to charity.
Risks Anthropic Warns About
The risk section runs more than 90 pages. The summary lists dependence on advanced models and enough compute, reliance on cloud partners that are also investors and customers, and the concentration of voting power.
It also warns that a catastrophic AI-related incident could be larger than the insurance industry could cover. Anthropic says people at risk of self-harm or violence have used its models despite safeguards, and that misaligned or autonomous model behavior is a real concern.
What This Means for You
If you use Claude at work or for coding, the filing shows how much the company is betting on business customers. It describes Claude Cowork adoption as faster than Claude Code at the same stage, and says Claude Opus 5.5 cut customer costs per task by about 40% versus Claude Opus 5.
- Users: expect continued heavy investment in Claude and its agent tools.
- Investors: read the risk factors and the control structure before the price is set.
- Businesses: a public Anthropic must publish regular financial reports, which makes vendor risk easier to judge.
- Watchers: this follows earlier coverage of the third-quarter revenue and the IPO pause request.
Nothing here is investment advice. The registration is not yet effective, and the terms can still change.

Conclusion
Anthropic’s public S-1 turns a private AI lab into a company anyone can analyze, with soaring revenue, enormous losses and a rare governance setup. The final share price and valuation are still to come, so the next filing update is the one to watch.
