Anthropic’s path to Wall Street began quietly in June, when the Claude maker confidentially submitted IPO paperwork. On Monday it made the move public, filing an S-1 to list Class A shares on Nasdaq under the ticker ANT; neither the number of shares nor the price range has been set.¹

The filing lands as the company’s commercial growth accelerates at an almost implausible pace. Revenue reached $16.3 billion in the first six months of 2026, up from $1.2 billion a year earlier, while operating losses narrowed to $693 million from $2.1 billion. Anthropic also reported $3.9 billion in operating cash flow and said adjusted operations produced a $1.6 billion profit.²

But the headline figure is harder to ignore: an $80.7 billion net loss. Much of it—$72.4 billion—came from a noncash accounting charge related to convertible notes, rather than day-to-day operations. Still, the prospectus concedes that Anthropic “may not achieve or sustain profitability in the future.”³

That caution reflects the brute-force economics of the AI race. The company has committed to enormous compute spending, including up to $120.5 billion with SpaceX by 2029, at least $114.5 billion with Google through 2033 and $110 billion with Amazon over the next decade.⁴ Reports have pointed to a Thanksgiving-week debut and a valuation of roughly $1.5 trillion to $2 trillion—an extraordinary wager that revenue can ultimately outrun infrastructure bills.²

Anthropic’s pitch is intentionally broader than a financial forecast. It says AI could speed scientific discovery, cure major diseases and tackle problems that have defied generations. Yet it pairs that promise with a warning that advanced systems, without safeguards and oversight, could pose “catastrophic or existential risks to humanity.”²

Its unusual governance is meant to keep that tension from being settled solely by quarterly markets. The seven founders’ LLC will retain 50.1% of voting power, while the Long-Term Benefit Trust can appoint most directors—leaving public shareholders with limited practical control.³ The IPO is therefore not simply a financing event. It is a test of whether investors will accept less influence in exchange for a stake in AI’s most ambitious—and openly anxious—business model.
