Anthropic outranks most IPOs in history
Background
Background
Anthropic is the maker of the Claude models. According to the prospectus, revenue rose from $41 million in 2023 to $16.3 billion in the first half of 2026, and its $132.9 billion accumulated deficit exceeds the $41.3 billion SpaceX disclosed at IPO, with $113.2 billion of Anthropic's figure tied to fair-value changes on convertible notes. Rival OpenAI raised $122 billion privately in March, a reminder that Anthropic's expected $100 billion in IPO proceeds would still trail the largest private raises.
Anthropic's IPO prospectus, filed on Monday, discloses an expected $1.5 trillion valuation — third-largest in IPO history behind Saudi Aramco's $1.7 trillion and SpaceX's $1.8 trillion — alongside 1,300% six-month revenue growth and a $66.3 billion second-quarter loss. The company says the loss is largely attributable to repriced convertible debt tied to its rising enterprise valuation.
The filing provides unusually detailed financial disclosure from a frontier AI lab ahead of what would be one of the largest listings on record, including revenue retention, compute commitments and accumulated deficit figures that are rarely visible for private AI developers.
Anthropic reports roughly 900% net revenue retention, but its definition includes customers who paid as little as $1 over a year and excludes Pro and Max subscribers. It also expects to spend $265.6 billion on computational services over the next few years and warns in the filing that it does not expect revenue to keep growing at comparable rates; other coverage of the filing has cited first-half net loss figures in the $80 billion range.

Impact analysis
An IPO raising the expected $100 billion would be the largest proceeds figure on record, absorbing substantial public-market capital and setting a new reference point for AI-linked equity valuations. That valuation channel has historically fed sentiment toward AI-themed crypto tokens, while the convertible-note revaluations tie reported results directly to changes in Anthropic's private valuation marks.
