Summary
Anthropic, the developer of the Claude AI model, submitted its S-1 registration statement to the U.S. Securities and Exchange Commission on Oct. 26, seeking a Nasdaq listing under the ticker ANT. Goldman Sachs and Morgan Stanley are leading the offering, which could become one of the largest in U.S. history. The company has not disclosed its proposed share price or offering size, and market expectations point to a November debut.
Valuation estimates diverge sharply. According to CryptoSlate, crypto trading platform Liquid reported that Anthropic's implied valuation fell roughly 2% to $1.88 trillion after the announcement. Better Markets quoted an indicative pre-IPO share price of $2,967.92, corresponding to an estimated $1.43 trillion valuation under its methodology. Simon Dedic, founder of Moonrock Capital, said he expects trading to begin by mid-November and described the listing as potentially either the "top of the AI bubble" or one of the largest wealth-creation events in private-market history. He argued that the offering could release substantial capital held by early investors and employees, some of which could flow into startups and other asset classes, including crypto.
The financial disclosures provide a clearer basis for assessing those valuations. Anthropic generated $16.3 billion in revenue in the first half of 2026, up from about $1.16 billion a year earlier. Quarterly revenue rose from $376 million in the first quarter of 2025 to $11.6 billion in the second quarter of 2026, according to figures Social Capital cited from the filing. Compute and infrastructure spending fell from about $2.51 per dollar of revenue in the first quarter of 2025 to about 48 cents by the second quarter of 2026, helping the company post $974 million in operating profit in the June quarter after a $1.67 billion operating loss in the prior quarter. The company nonetheless reported a $66.3 billion net loss for the quarter and an $80.7 billion first-half net loss, largely reflecting $59.6 billion and $72.4 billion respectively in fair-value adjustments tied to convertible notes, derivatives and related financing instruments. Venture capitalist Nic Carter described the results as "robust and improving," while questioning whether a valuation approaching $1.5 trillion could be justified at roughly 22 times annualized third-quarter revenue. Milk Road AI analyst Melvin pointed to approximately $131.7 billion in cash and short-term investments as evidence that frontier AI developers may not need continual external capital.
Infrastructure obligations represent a significant risk. Anthropic has agreements with Amazon, Google, Microsoft and other providers involving hundreds of billions of dollars in potential spending over several years, including up to $120.5 billion through 2029 under its SpaceX arrangements. These contracts include cancellation provisions after initial noncancelable periods. Approximately 80% of first-half revenue came from consumption-based services, which allow customers to reduce spending faster than the company can unwind commitments. Anthropic warned that weaker demand could leave it unable to meet minimum payments, potentially triggering defaults and accelerated repayment under related financing. It has expanded its revolving credit commitments to $15 billion and faces a minimum quarterly liquidity requirement of $5 billion beginning at the end of 2026.
The prospectus also outlines a staggered lock-up structure. Certain shareholders may sell limited portions of their holdings from the first trading day, with additional releases scheduled afterward. Some employees may sell immediately, while other investors face restrictions of up to 180 days. Co-founders and certain major shareholders face restrictions of up to 365 days, with specified early releases. The structure could spread selling across several months rather than concentrating it at a single expiration. The filing has not yet established the final offering size or share count, so the dollar value of stock that could reach public markets at each stage remains undetermined.
