Will December be the best month for Bitcoin in 2026?

This market prices December 2026 as an unlikely best-performing month for Bitcoin at just 17% implied probability, yet offers an exceptional 686% annualized yield for "Yes" positions—a stark asymmetry suggesting either deep skepticism about December seasonality or significant mispricing. The extremely thin liquidity of $26.68 in 24-hour volume relative to $9.99M open interest raises concerns about execution risk and potential slippage, while the 2¢ spread is relatively wide for such a low-priced contract. With 260 days to expiration and neutral regime conditions, the market appears to be pricing in a mean-reversion view where December's historical strength may not repeat, though the outsized yield warrants caution about whether this reflects genuine conviction or merely illiquidity-driven pricing.

Resolution rules

This market will resolve to the calendar month in 2026 during which Bitcoin has the highest percentage change. The “Change” value shown for each monthly candle will be used. A monthly candle is considered finalized once the following month’s candle is published. The resolution source is Binance, using the BTC/USDT trading pair: https://www.binance.com/en/trade/BTC_USDT If two or more months are tied for the highest percentage change, this market will resolve to the earliest month chronologically. Only Binance BTC/USDT data will be used. Prices from other exchanges, trading pairs, or data sources will not be considered. If it becomes impossible for a given month to have the highest percentage change in 2026, that outcome may resolve to “No” immediately.
