Anthropic IPO Closing Market Cap

Anthropic IPO Closing Market Cap is a finance prediction market that asks traders to forecast Anthropic’s market capitalization at the closing price on its first day of trading. The event centers on whether the AI company completes an initial public offering and, if so, what valuation bracket it lands in based on the official first-day closing price and shares outstanding. If Anthropic does not go public by June 30, 2026, 11:59 PM ET, the market resolves to “No IPO by June 30, 2026.”

This event matters because Anthropic is one of the most closely watched AI companies, and its IPO would be a key signal for broader tech and Big Tech market sentiment. Current market probability is about 15%, suggesting traders see a relatively low but still meaningful chance of an IPO-related resolution before the deadline. The forecast relies on official exchange data, with fallback sourcing if the primary listing page does not show the relevant figure. The market opened on September 23, 2025 and runs through June 30, 2026, making it a long-dated event prediction tied to AI, IPOs, and finance.
