About this event

This event tracks Anthropic's market capitalization at the close of its first day of public trading, provided the initial public offering occurs by December 31, 2027. Markets evaluate different valuation brackets or whether no IPO happens before the deadline.

How the outcomes relate

The event is structured as mutually exclusive valuation brackets alongside an outcome for no public debut occurring before the deadline. Because market capitalization takes a single closing value on IPO day or no IPO takes place, at most one market can resolve Yes.

How it resolves

Each market resolves to Yes if Anthropic completes an IPO by December 31, 2027, and its market capitalization on its first day of trading falls into the specified bracket; otherwise, it resolves to No. Market capitalization is calculated as outstanding shares multiplied by the closing price on day one. If the value lands exactly between two brackets, it resolves to the higher bracket. If no IPO occurs by 11:59 PM ET on December 31, 2027, the market resolves to the designated outcome indicating no IPO. If trading is interrupted, the official closing price of the abbreviated session or the next available session with an official closing price is used.
