Anthropic made $16.3 billion in revenue during the first half of 2026, and lost $80.7 billion over the same stretch, according to a Wall Street Journal report published Tuesday. The figures come from a draft of Anthropic’s IPO prospectus that the Journal reviewed, offering the first detailed look at the Claude maker’s 2026 finances ahead of its planned public listing.
The loss is one of the largest half-year deficits ever disclosed by a private company. A year earlier, Anthropic lost $13 billion on just $1.1 billion of revenue, per the same report, which Reuters also covered.
Most of the loss is accounting, not cash
The headline number looks catastrophic, but Anthropic’s actual cash burn is far smaller. About $72 billion of the $80.7 billion loss comes from non-cash accounting charges tied to changes in the value of convertible notes and other financing instruments the company used to raise money, according to the Reuters account of the report. As Anthropic’s valuation climbed, those paper adjustments ballooned along with it.
The pattern matches last year’s numbers. Anthropic recorded a GAAP net loss of roughly $42 billion in 2025, but stripped of the non-cash items, the operating loss came to $8.06 billion, Crypto Briefing notes, with compute and infrastructure spending of $7.33 billion making up most of the real cash outlay.
The third-quarter turn
Buried in the same draft filing is a sharp change in trajectory. Anthropic told IPO investors it made $16.8 billion in revenue in the third quarter of 2026 alone, more than in the entire first half, and said it reached adjusted profitability and positive cash flow during the quarter.
That suggests the first-half figures describe a company at peak investment, not one sliding into trouble. Revenue grew from just under $5 billion in the first quarter to about $11.5 billion in the second, and the company grew full-year revenue from 2025’s $4.6 billion at a pace that would have seemed implausible two years ago.
A $518 billion compute bill
The draft filing also lays out what Anthropic has promised to spend to keep growing. Its future compute, cloud, and infrastructure commitments total at least $518 billion over roughly a decade, with recent reports suggesting the true number could exceed $600 billion. About 80% of those commitments are non-cancellable.
That bill explains the financing structure that produced the paper losses. Anthropic is signing enormous long-term capacity contracts to train and serve its models, then raising the money to fund them through instruments whose rising value generates the accounting charges.
Why it matters
Anthropic filed its confidential S-1 draft with the SEC on June 1, and the IPO is tentatively expected in November 2026. The company has not publicly confirmed the draft figures, which may change before the filing goes public on EDGAR.
If it lists, Anthropic would be the first of the frontier AI labs on the public market, and its numbers will set the benchmark for the whole industry, including rival OpenAI, which is racing to close its own $30 billion raise ahead of Anthropic’s debut. The question for investors is whether they will price the company on the cash-generating business it claims to have become in Q3, or on the $80.7 billion headline that will dominate the conversation until then.
