Full rules

As written on Polymarket for “Will Anthropic's public ticker be $CLAU?”.

1. §1An official announcement from Anthropic that it will IPO under a specific ticker symbol will be sufficient to resolve this market.
2. §2If a ticker used by Anthropic in a qualifying IPO is a variant of a ticker symbol listed in this market group with additional letters to denote a specific class of shares, it will be considered to be that ticker (e.g. if Anthropic uses a ticker symbol of $ANTH.A or $ANTHA, this market will resolve to $ANTH).
3. §3If Anthropic announces an IPO with multiple tickers that are not considered the same ticker under the previous rule (i.e. $ANTH.A and $ANTH.B would be considered the same ticker), this market will remain open until Anthropic's first day of public trading and will resolve according to the ticker symbolizing the security class with the greatest market capitalization.
