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.

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. (.
