This market will resolve based on Anthropic's market capitalization at the closing price on its first day of trading. If no IPO occurs by December 31, 2027, 11:59 PM ET, the market will resolve to "No IPO by December 31, 2027". Market capitalization expresses the monetary value of a company’s outstanding shares, stated in its pricing currency. It is calculated as the number of shares outstanding multiplied by the closing share price on the first trading day. If the relevant value falls exactly between two brackets, then this market will resolve to the higher range bracket. Resolution will be based on the primary exchange’s official listing page. In the event that the relevant figure is not displayed, another reliable source will be used. In the event of an interruption in the course of the normal trading session on Anthropic’s first day of trading (e.g., a circuit breaker or half-day), the market will resolve according to the official closing price of the abbreviated session. If no such official closing price is published, the market will resolve according to the next trading day on which an official closing price is published, treating that as the first day of trading for purposes of this market.
Rapid revenue growth underpins the 94.3% market-implied odds for Anthropic’s IPO closing market cap exceeding $600 billion. The company’s annualized run rate surged from roughly $9 billion at the end of 2025 to $65 billion by July 2026, following its $65 billion Series H round at a $965 billion valuation and confidential S-1 filing in June. Bankers have discussed a potential $2 trillion IPO valuation and $100 billion raise as early as October 2026, exceeding SpaceX’s recent debut and reflecting strong enterprise adoption of Claude models. This positions trader consensus around skin-in-the-game expectations of continued scaling in large language model capabilities. Delays, a broad AI market correction, or regulatory hurdles could still compress the outcome, though current momentum makes lower brackets unlikely.
