Anthropic, the maker of the Claude AI assistant, filed to sell shares to the public on Monday, October 26, in a move that could produce one of the largest stock market debuts on record. The filing puts the AI industry’s rapid growth, its safety concerns and its business outlook in front of investors.
Disclosure: This article was prepared with the assistance of Claude, an AI assistant made by Anthropic, the company at the center of this story.
What Anthropic Filed
Anthropic said in its regulatory filing that it will list on the Nasdaq Global Select Market under the ticker “ANT,” according to the Associated Press. The Hill reported that the debut could come as soon as November.
The AP said the offering could eclipse SpaceX’s record $86 billion IPO in June. The size of Anthropic’s offering has not been confirmed in the filing excerpts reviewed.
Growth and Losses
Anthropic reported revenue of $16.3 billion in the first half of 2026, up 1,300% from a year earlier, BNN Bloomberg reported. The company reported a net loss of $80.7 billion for the first half of 2026, but that headline figure was largely driven by a one-time, noncash accounting adjustment tied to convertible debt; its reported operating loss was far smaller. Readers should distinguish the net-loss figure from the company’s operating performance. It was valued at $965 billion by private investors earlier this year, the AP reported, as cited by The Hill.
CNBC reported that consumption-based revenue made up $13.1 billion, or 80% of the total, for the six months ended June 30.
Safety Warnings in the Filing
The 335-page filing describes AI as one of the most consequential technologies in human history. It also weighs concerns that AI could lead to “catastrophic or existential risks to humanity,” BNN Bloomberg reported.
The AP noted that the filing comes weeks after CEO Dario Amodei argued in an essay for slowing the development of the most advanced AI models. The same AP report said an IPO could give the company resources to accelerate its expansion. How those two positions fit together is a question the filings do not answer directly.
The Bubble Debate
BNN Bloomberg said the filing has renewed questions about whether the AI industry is in a bubble. The Hill described the offering as a major test of investor interest in AI. Other firms are also expected to test the market: the AP said the move puts Anthropic ahead of rival OpenAI in going public.

What Remains Uncertain
The IPO has not priced, and the final timing, price and amount raised are not known. Reports of the planned raise vary, and one market newsletter put it as high as $95 billion, a figure not confirmed in the AP, The Hill or BNN Bloomberg reports reviewed. This article reports the company’s statements and press coverage, not a prediction of how the shares will trade, and it is not investment advice.
