Another S&P 500 Company buys Bitcoin by ___?

"Another S&P 500 Company buys Bitcoin by ___?" is a crypto prediction market focused on whether a second S&P 500 company will announce its first Bitcoin purchase within the market window. The event resolves to Yes if any qualifying S&P 500 company publicly states between November 4, 2025, 12:00 PM ET and November 30, 2025, 11:59 PM ET that it bought Bitcoin for the first time, based on official company announcements or credible reporting. This makes the forecast straightforward: traders are not predicting price direction, but a corporate adoption event tied to Bitcoin and major U.S. equities. Market sentiment currently implies about a 24.75% probability of a Yes resolution, suggesting traders see the outcome as possible but not likely. The event matters because new S&P 500 Bitcoin purchases can signal broader institutional acceptance of crypto and may influence how markets interpret corporate treasury strategy. As a Bitcoin event prediction, it sits at the intersection of crypto, equities, and headline-driven probability markets.
