Analysis
Anthropic confidentially submitted a draft Form S-1 to the SEC on June 1, 2026, officially starting its IPO process, with forecasters at Forge and FutureSearch putting a target pricing date around November 30.
The filing follows a $65 billion Series H closed in May 2026 at a $965 billion post-money valuation. Anthropic disclosed more than $47 billion in run-rate revenue as of mid-May -- the kind of growth trajectory that public-market investors have been willing to pay a premium multiple for all year.
The math behind $1 trillion-plus
Median forecaster expectations put Anthropic's 90-day post-IPO market cap at $1.14 trillion, which would place it alongside SpaceX's roughly $1.77 trillion June 2026 debut as one of the two largest tech listings in history. That number isn't pulled from nowhere: it implies roughly a 20x multiple on run-rate revenue at IPO, in line with where OpenAI and other frontier labs have been valued in recent private rounds, and below the multiple SpaceX commanded on a business with a longer profitability track record.
What could break the math
The gap between a $965 billion private mark and a $1.14 trillion public one is thinner than it looks -- public markets have not yet tested whether they'll pay AI-lab multiples on AI-lab volatility, and Anthropic's Q2 2026 revenue of $11.5 billion (turning adjusted operating income positive for the first time) is the first quarter of profitability investors will actually get to see before pricing. A disappointing print between now and November, or a broader AI-multiple compression like the one already hitting CoreWeave and other infrastructure names, would pressure the number down before the road show even starts. Nvidia CEO Jensen Huang has signaled the chipmaker's current stake is likely its last private investment in Anthropic, which reads as smart-money positioning for the handoff to public markets rather than a vote of continued private-round support.
