This market will resolve to “Yes” if Bitcoin comparatively outperforms the S&P 500 (SPX) in December 2025, with performance measured as the percentage change in price during the month for each asset. Otherwise, this market will resolve to “No”.

The percentage change in price for Bitcoin will be calculated by comparing the "Close" price for the Binance 1 minute candle for BTC/USDT December 31, 2025 11:59 PM in the ET timezone to the "Close" price for the Binance 1 minute candle for BTC/USDT December 1, 2025 12:00 AM in the ET timezone.

If either of the relevant days have no official closing price (for example, due to a trading halt into the market close, system issue, delisting, or other disruption), the market will use the last valid on-exchange trade price of the regular session as the effective closing price.
