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.Anthropic’s rapid private valuation surge to $1.32 trillion and investor targets near $2 trillion underpin the dominant 1.8T+ market-implied odds for its IPO closing market cap. Explosive annualized revenue growth past $65 billion, driven by Claude large language model adoption and enterprise demand, plus the June 2026 confidential S-1 filing, have positioned the company for a potential fall 2026 Nasdaq debut led by major underwriters. Recent timeline shifts to mid-October marketing keep the 2026 window intact while highlighting strong AI capabilities and competitive positioning against OpenAI. Traders view the $1.8T+ bracket as reflecting sustained momentum from these developments, tempered by typical IPO volatility and execution risks around regulatory review and market conditions.
