The AI company's prospectus omits recent revenue and compute contract totals despite outlining massive future payment obligations.
Anthropic has filed an S-1 prospectus to go public on the Nasdaq under the ticker symbol ANT, according to reporting from Wired. While the filing details a rapid enterprise expansion—with revenue growing from $0 at its first-quarter 2023 launch to more than $16 billion through the first half of 2026—it contains notable omissions regarding its most recent financial performance.
Specifically, the filing redacts revenue figures for the three months ended September 30, 2026. Additionally, Anthropic has omitted the aggregate committed spend for contracts related to compute and infrastructure, some of which extend through 2045. The company identifies compute as its most significant operating cost and a primary business risk, citing concerns over both undersupply and overinvestment.
Despite these redactions, the prospectus provides specific estimates in its footnotes. Anthropic reports future minimum payment obligations for compute and infrastructure leases totaling approximately $417 billion since December 31, 2025, and an additional $245 billion added since June 30. Including short-term agreements and pending commercial expansions, the company estimates its minimum total obligations at $808 billion.
Other financial disclosures reveal a widening net loss. In the first half of 2026, Anthropic's net loss reached $80.7 billion, a significant increase from the $13 billion loss reported during the same window in 2025. While The New York Times reported in August that the company sought a valuation around $2 trillion and aimed to raise over $100 billion, the S-1 does not specify a target valuation or fundraising goal.
Patrick Moorhead, CEO and chief analyst at Moor Insights & Strategy, told Wired that Anthropic owes investors more detailed information regarding the probability and impact of its identified risks. Michael Dambra, a professor at the University at Buffalo School of Management, noted that while redactions are common, they are often viewed as controversial and may lead companies to underprice their shares.
