Anthropic officially files for its public debut

Anthropic filed for an initial public offering on Monday and plans to list its shares under the ticker symbol “ANT.” Its SEC filing reported $16.3 billion in revenue for the first half of 2026, compared with $1.2 billion during the same period in 2025. Operating losses narrowed to $693 million from $2.1 billion a year earlier, while net loss reached $80.7 billion, largely because of noncash accounting adjustments related to convertible debt. Anthropic said it may not achieve or sustain profitability. Anthropic reported more than 11,900 customers spending at least $100,000 annually as of the end of September, including 1,900 spending at least $1 million and about 250 spending at least $10 million. The company has not disclosed its target fundraising amount or proposed share price. Seven co-founders will form a Founder LLC holding 50.1% of shareholder voting power after the listing: Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish, and Christopher Olah. Anthropic says the arrangement is intended to preserve its AI safety mission. Its Long-Term Benefit Trust, created in 2023 to support its public-benefit mission, will be able to appoint most board members. Anthropic’s filing acknowledges that its technology may pose catastrophic or existential risks to humanity.
