Anthropic filed a registration statement with the Securities and Exchange Commission on Monday, October 26, 2026, the public step toward a stock market debut that investors have been pricing in for months. The company is asking to list its Class A common stock on the Nasdaq Global Select Market under the ticker ANT.
The filing follows a confidential submission made in June, which gave the SEC time to review the company's accounts before the figures became public.
What the numbers show
Anthropic reported roughly $16.3 billion in revenue for the first half of 2026, against about $1.2 billion in the same period a year earlier.
The loss line is harder to read at a glance. The company reported a net loss of $80.7 billion for the period — a figure dominated by a large non-cash revaluation charge tied to financing instruments rather than by the cost of running the business. Set that aside and the operating loss was $693 million.
Goldman Sachs and Morgan Stanley are leading the underwriting syndicate. The number of shares and the offering price have not been set, and the registration statement has not yet become effective. Those are the two blanks that will decide what the company is worth on its first day of trading.
The valuation question
Reports put the valuation Anthropic is aiming at between $1.5 trillion and $2 trillion, and The Wall Street Journal has reported that the company could raise $100 billion or more, with trading possibly starting the week of November 16. Both the range and the timing are provisional until a price is filed.
For scale, the company's last private round — a Series H in May backed by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital — raised $65 billion at a post-money valuation of $965 billion. The range now being discussed is roughly twice that, about six months later.
A market already paying for AI
The filing landed in a market that spent Monday buying the same theme. The Nasdaq Composite closed at 26,169.38, up 0.82%; the S&P 500 at 7,676.80, up 0.70%; and the Dow Jones Industrial Average at 52,361.52, up 0.28%.
On the same day, Meta set out plans to raise $95 billion for artificial intelligence infrastructure — first $35 billion through underwritten public equity offerings, then $60 billion through an at-the-market programme, alongside operating cash flow, investment-grade debt and partnerships. Nvidia, AMD and Broadcom were reported to be interested in buying up to $5 billion of the shares. Meta's own stock fell 1.70% in early trading.
The week's other fixture is the Federal Reserve, which began a two-day meeting on Tuesday. Markets were pricing only about a 10% chance of a rate move at this meeting, according to Capital.com analyst Kyle Rodda, and were watching instead for any signal about December.
