How This Resolves
If CoreWeave is announced to be or is officially added to S&P 500 during July 1, 2026 to September 30, 2026, then the market resolves to Yes. The market resolves to Yes if either the index administrator officially announces the membership change OR the change takes effect during the specified time period, whichever occurs first. The effective date of the change need not fall within the time period; only the announcement or implementation must occur within the time period. Temporary suspensions do not constitute removal unless explicitly designated as permanent by the index administrator. If an announced addition or removal is subsequently reversed due to error within the time period, the Exchange will determine resolution at its discretion. For companies undergoing mergers, acquisitions, or restructuring, removal from the index due to such corporate actions constitutes removal for purposes of this market. If a spin-off or successor entity is immediately added in place of the original company, the original company is still considered removed. Regular scheduled rebalancing events count as additions or removals if the company's membership status changes during such rebalancing.

This market resolves to Yes if CoreWeave is announced to join or is officially added to the S&P 500 between July 1, 2026 and September 30, 2026. Resolution occurs on the first of either the official announcement by the index administrator or the effective date of the change, even if the effective date falls outside the period. Reversals of an announcement due to error within the timeframe are resolved at the exchange's discretion.
