The S&P 500 undergoes quarterly reconstitution on the third Friday of March, June, September, and December. The next rebalance is currently scheduled for December 18, 2026.

This market will resolve to "Yes" if S&P Global Inc. announces that the listed company will be added to the S&P 500 index by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No."

To qualify, the listed ticker must match the announced ticker added to the index.

An announcement from S&P will qualify for a "Yes" resolution, regardless of whether the listed company has actually been added to the S&P 500 index by the resolution date.

The primary resolution source will be official announcements from S&P Global Inc. (https://www.spglobal.com/en/press/press-release).
