Analysis

4d ago

This market shows extreme illiquidity with zero 24-hour volume and only $45 open interest, making the 4¢ price potentially unreliable for actual trading. The astronomical 3386% implied yield on the Yes side combined with 12140% realized volatility suggests the market has experienced dramatic price swings from minimal trading activity rather than genuine probability discovery. With Sofia historically ranking around #1 in recent years according to SSA data, the 4% probability appears significantly underpriced, though the illiquidity and long 259-day expiry window mean this mispricing may persist without meaningful order flow.
