The S&P 500 undergoes quarterly reconstitution on the third Friday of March, June, September, and December. This market will resolve to "Yes" if S&P Global Inc. announces that SpaceX will be added to the S&P 500 index by March 31, 2027, 11:59 PM ET. Otherwise, this market will resolve to "No." 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).
