This market will resolve to "Yes" if any S&P 500 company announces between November 4, 12:00 PM ET, and November 30, 2025, 11:59 PM ET that they bought Bitcoin for the first time. Otherwise, this market will resolve to "No".

The primary resolution source will be official announcements from qualifying companies; however, a consensus of credible reporting will also be used.
