Anthropic filed its S-1 and plans to list on Nasdaq as ANT: Reveneau

Why it mattersA team buying Claude for production now has public numbers for its vendor. Those numbers include 11,900 enterprise customers over 100,000 dollars a year. They also include 808 billion dollars in compute commitments.

Anyone buying Claude for a production system now has public numbers on the vendor behind it. Anthropic filed its S-1 with the Securities and Exchange Commission on 26 October. The company plans to list on Nasdaq under the ticker ANT, Wired reports.

The filing records 16.286 billion dollars of revenue in the first half of 2026. The 2025 total was 4.585 billion. 2024 was 386 million. 2023 was 41 million. Wired cites a Wall Street Journal report that the IPO could come as early as November.

The customer and revenue numbers

The S-1 says 11,900 customers spent 100,000 dollars or more with Anthropic in the trailing twelve months. 1,900 spent more than 1 million. 250 spent more than 10 million. The filing frames those tiers as its measure of enterprise adoption. It excludes Claude Pro and Max subscribers from the Net Revenue Retention metric. Those fixed subscriptions do not show expansion or contraction.

The 80.7 billion dollar loss, read against the operating line

Wired reports a net loss of 80.7 billion dollars in the first half of 2026. The same period a year earlier was a 13 billion loss. The filing itself breaks that number down. Operating loss for the first half of 2026 was 693 million dollars. The rest, 72.388 billion, is a non-cash charge. It covers the change in fair value of convertible notes, derivative liabilities and SAFEs. Full-year 2025 net loss was 41.965 billion by the same accounting.

Compute commitments through 2045

The S-1 calls chips "the most significant operating cost in our business." It says Anthropic treats them as one pool. The filing names Amazon, Google, Nvidia and AMD as the suppliers in that pool. Anthropic has started or amended compute leases worth about 417 billion dollars since 31 December 2025. That number comes from the footnotes, Wired reports. Another 245 billion was added since 30 June. Anthropic says 125 to 150 billion more sits in agreements "not yet finalized." Short-term non-cancellable payments add another 21 billion. The company's total minimum obligation on compute is roughly 808 billion dollars. Some contracts run through December 2030. Others extend to 2045.

The risks the filing names

The S-1 lists one risk factor as "catastrophic or existential risks to humanity" from advanced AI. Wired reports the same line. The filing warns that sophisticated AI could be used by threat actors for cyberattacks. It could be used to develop biological weapons. It could be used by authoritarian governments to surveil citizens.

Wired cites Michael Dambra, an accounting professor at the University at Buffalo. Dambra says the prospectus leaves several figures as blanks because third-quarter numbers "take time" to close. SEC rules require Anthropic to update the filing with third-quarter financials if the IPO happens later than mid-November.

For a team that depends on Claude, the number worth watching sits further down the filing. Anthropic has promised to buy 808 billion dollars of compute. The filing says compute is where its money goes. A product roadmap built on current Claude prices should assume those prices move as Anthropic pays those compute bills.
