Anthropic’s confidential S-1 filing on June 1, 2026, combined with its explosive revenue trajectory—Q2 revenue exceeding $11.5 billion and an annualized run rate above $65 billion—has anchored trader expectations for an October 2026 debut at roughly 69% implied probability. Preparations with lead underwriters Morgan Stanley, Goldman Sachs, and JPMorgan, alongside investor briefings signaling a potential record raise near or above SpaceX levels at a $2 trillion valuation, have reinforced the timeline. Public filing could occur by month-end, enabling a September roadshow and October listing ahead of rival OpenAI’s 2027 plans. Market-implied odds reflect the compressed SEC review window typical for high-profile technology issuers and sustained AI-sector demand, though final timing remains subject to regulatory pacing and broader equity conditions.

An IPO refers to Anthropic shares becoming listed and open for trading on a public securities exchange, whether through a traditional initial public offering or a direct listing.
If Anthropic goes public through a merger, acquisition, or absorption by an entity that is already publicly traded, including a special purpose acquisition company, this market will resolve to "No IPO before 2028".
If no IPO occurs by December 31, 2027, 11:59 PM ET, the market will resolve to "No IPO before 2028".
Announcements, filings, or scheduling of an IPO will not suffice; this market will resolve after public trading has begun.
Resolution will be based on information from the primary exchange.
