Anthropic IPO Closing Market Cap

Anthropic IPO Closing Market Cap is a finance prediction market asking traders to forecast Anthropic’s market capitalization at the closing price on the company’s first day of trading. The event focuses on the expected valuation of the AI and Big Tech company behind Claude, and it will resolve using the official primary exchange listing page or another reliable source if needed. If Anthropic does not complete an IPO by December 31, 2027, 11:59 PM ET, the market will resolve to “No IPO by December 31, 2027.”

This event matters because Anthropic is one of the most closely watched names in artificial intelligence, and its IPO valuation would signal market sentiment around AI companies, public-market demand, and broader tech sector expectations. The forecast is structured around bracketed market-cap ranges, with the higher range used if the final value falls exactly between two brackets.

As of the latest data, the market probability is 1.3%, suggesting traders currently see a low chance of the listed outcome relative to the available brackets. The market begins on April 30, 2026 and runs until the end-of-year deadline in 2027.
