Important information: We would like to clarify that this market will resolve on the GICS sector that S&P Global (S&P Dow Jones Indices / MSCI) assigns to Anthropic. GICS sector classifications are assigned at the company level based on a company's principal business activity, separately from S&P 500 index membership.
Anthropic does not need to be added to or be a member of the S&P 500 for this market to resolve — it resolves on the first GICS sector S&P Global assigns to Anthropic, whether or not Anthropic is a S&P 500 constituent.
To avoid further confusion, we have changed the titles of these events to “What sector will Anthropic be assigned to?”

If Anthropic is assigned to more than one sector of the || Index ||, then "Yes" holders for any attributed sector will receive $1/number of sectors and "No" holders for those sectors will receive $1 minus "Yes" payout.
