Anthropic Files for Nasdaq IPO Under Ticker ANT, Discloses $80.7 Billion Loss

Anthropic publicly filed its S-1 registration statement with the Securities and Exchange Commission on October 26, confirming plans to list on the Nasdaq under the ticker symbol ANT. Goldman Sachs and Morgan Stanley are leading the offering, according to the filing, though the company has not yet set the number of shares, the price range, or a confirmed trading date. Anthropic is reportedly targeting a public listing during the week of November 16, though the company cautioned that timing could change depending on market conditions.

Revenue Tripled, But So Did the Loss

The filing discloses revenue of $16.3 billion for the first half of 2026, up sharply from roughly $1.2 billion in the same period a year earlier. Against that growth, Anthropic reported a net loss of $80.7 billion for the same six-month period. The company says the overwhelming majority of that figure — approximately $72 billion — reflects a non-cash accounting charge tied to changes in the fair value of convertible notes and other financing instruments issued in earlier funding rounds, not cash burned on operations. On an adjusted operating basis, which excludes that charge, Anthropic reported positive operating income of $1.6 billion for the first half of the year.

The distinction matters for how investors read the filing: a company reporting an $80 billion loss alongside a $2 trillion target valuation looks alarming at first glance, but the underlying operating business is already generating positive adjusted income, with the headline loss driven by accounting mechanics tied to the valuation gains built into Anthropic's own convertible securities from prior private rounds.

A Valuation Range, Not Yet a Number

Anthropic has not disclosed a target valuation in the filing itself. Reports citing people familiar with investor discussions put the expected range between $1.5 trillion and $2 trillion, with the offering potentially raising $100 billion or more. For comparison, Anthropic's most recent private funding round — a $65 billion Series H — valued the company at $965 billion. A successful IPO at the high end of the reported range would roughly double that valuation within months and place the offering among the largest in Nasdaq history.

Massive, Mostly Binding Compute Commitments

The prospectus discloses extensive infrastructure obligations tied to training and running Anthropic's models, with total planned cloud and compute commitments reported in the hundreds of billions of dollars, and roughly 80% of those obligations described as binding and non-cancelable. Earlier reporting on a draft version of the filing detailed a breakdown including approximately $111 billion owed to Google, $110 billion to Amazon, $31 billion to Microsoft, and $161 billion to Broadcom — underscoring how dependent frontier AI labs have become on locking in compute capacity years in advance, often at a scale that dwarfs current revenue.

Founder Control and Governance Structure

The filing outlines a Founder LLC structure that gives Anthropic's co-founders — including chief executive Dario Amodei, president and board chair Daniela Amodei, and chief compute officer Tom Brown — combined voting control of 50.1% through a dedicated class of shares, a mechanism that remains in place until the number of founders still involved in the company drops to two or fewer. The co-founders have separately pledged to donate 80% of their personal equity to charity. Anthropic's Long-Term Benefit Trust, an independent governance body with authority over some board seats, includes former Federal Reserve chair Ben Bernanke among its members.

Unusual Risk Factors for a Public Filing

Observers have noted that the risk-factors section of Anthropic's prospectus — reportedly running to roughly 80 pages — includes disclosures not typically found in a corporate S-1, including risks related to self-preserving behavior in its AI models, resistance to being shut down, and the potential for a model to engage in blackmail-like behavior during testing. The unusual candor reflects Anthropic's public positioning as a safety-focused AI lab, but it also means prospective public shareholders are being asked to weigh risks specific to frontier AI development alongside the ordinary financial risks of a richly valued, fast-growing, deeply unprofitable company.

The IPO also arrives against a tense regulatory backdrop: in late September, a U.S. federal appeals court upheld a Pentagon classification of Anthropic as a supply-chain risk under federal acquisition security rules, a designation the company has contested. How that classification affects a public offering, if at all, was not addressed in the filing.
