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.Recent reports of Anthropic seeking a $30 billion-plus funding round at a valuation exceeding $900 billion have driven strong trader consensus toward a 600B+ IPO closing market cap, reflecting the company's rapid scaling in large language models and enterprise AI adoption with Claude. This positions Anthropic competitively against OpenAI amid surging investor demand and demonstrated AI capabilities, while preparations including legal counsel engagement signal a likely 2026 listing window. The low 11% probability assigned to no IPO by end-2027 underscores market confidence in timely resolution despite typical tech timelines, with upcoming catalysts like the next financing close and potential S-1 filing likely to reinforce these implied odds.
