Anthropic files for Nasdaq IPO under ticker ANT

The S-1 showed rapid revenue growth alongside steep losses. Anthropic reported $16.3 billion in revenue for the first half of 2026, up from about $1.2 billion in the same period a year earlier, according to the filing. Its net loss reached $80.7 billion, compared with $13 billion a year earlier, while its operating loss narrowed to $693 million from $2.1 billion. TechCrunch reported that the net loss was largely driven by noncash accounting adjustments tied to convertible debt. The company said it “may not achieve or sustain profitability in the future.”

Anthropic also gave investors a fuller view of its enterprise business. As of the end of September, it had more than 11,900 customers spending $100,000 or more annually, 1,900 spending $1 million or more and about 250 spending $10 million or more, according to TechCrunch’s reading of the filing. SiliconANGLE reported that Anthropic last raised $65 billion in May at a $965 billion valuation, and that data presented at a recent investor event put its valuation at $1.5 trillion, down from $2 trillion. The filing itself did not set a valuation.

The company’s governance structure will give its seven co-founders control after the listing. Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish and Christopher Olah will form a “Founder LLC” holding 50.1% of shareholder voting power, TechCrunch reported. A Long-Term Benefit Trust established in 2023 will have authority to appoint most of the board. Anthropic says the structure is meant to preserve its AI safety mission; TechCrunch reported that it is controversial because voting power will not be proportional to the founders’ economic ownership, leaving public shareholders with little practical control.

In the filing, Anthropic described AI as “one of the most consequential technologies in human history” and said that, if managed well, it could accelerate scientific innovation, raise economic growth, bring major disease cures within reach and solve problems that have resisted generations of human effort. It also listed risks, including that its success depends on continuing to develop the most advanced and capable AI models, that its models could develop faster than the company can keep them safe, that they could be used to cause harm or take harmful actions on their own, and that its policy views could draw heightened scrutiny or political backlash.

The filing comes amid continuing controversy over Anthropic’s safety stance and its disputes with the Pentagon. NPR reported that Anthropic clashed with the Pentagon this year over military use of its models, with Amodei drawing a line against autonomous weapons and mass surveillance of Americans. The Pentagon blacklisted Anthropic and designated it a “supply chain risk,” a label previously reserved for entities affiliated with U.S. adversaries, and Anthropic has sued in two federal district courts. Those cases remain ongoing. Amodei has also warned about AI spiraling out of control and urged companies to “pace the frontier,” or slow development of their most capable models.

The IPO could take place as soon as November, with Engadget reporting expectations for a mid-November debut. It would arrive after SpaceX listed in June at a valuation of about $1.8 trillion; SpaceX raised more than $86 billion after opening, and its shares briefly soared before returning to around $150, NPR reported. AI-related stocks have been volatile. CoreWeave’s share price fell this month on concerns about financing its expansion, and Intel, Meta and Nvidia have also slid in recent weeks. Jim Angel, a markets specialist at Georgetown University, told NPR that going public brings capital and liquidity but that “there’s concern that we may be in an AI bubble.” OpenAI, Anthropic’s main rival, has been expected to pursue a listing as soon as 2027, though NPR reported that its IPO plans were temporarily on hold this year.

Editor's Summary

Anthropic’s S-1 sets up a Nasdaq listing under ANT and discloses $16.3 billion in first-half revenue against an $80.7 billion net loss. The filing also locks in founder control and flags AI safety, regulatory and military-use disputes as risks. The IPO’s timing and valuation will test investor appetite for AI companies amid volatile markets and concerns about an AI bubble.
