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 valuation trajectory from $380 billion in its February Series G to $965 billion post-money after the $65 billion Series H in May underpins the 49% market-implied probability for an IPO closing market cap above $1.8 trillion. Strong run-rate revenue of $47 billion, combined with major compute partnerships across AWS, Google Cloud, and new infrastructure ventures, signals robust scaling of its Claude large language models ahead of the targeted September–October 2026 IPO window following the June S-1 filing. Traders appear to price in continued momentum from recent model releases and regulatory compliance moves, though any slippage in the fall timeline or broader market conditions could still compress the final valuation into the $1.5–1.8 trillion bracket.
