Anthropic IPO: market cap at the close of its first trading day
Market Rules
This event covers only Anthropic's first day of trading after its initial public offering (IPO), if it occurs by December 31, 2027, 11:59 PM ET. The market whose range contains Anthropic's market capitalization at the official closing price of that day — shares outstanding multiplied by the closing price, per the primary exchange's official listing page — resolves "Yes"; if no IPO occurs by then, "No IPO by December 31, 2027" resolves "Yes". Exactly one outcome wins.
