Analysis

5d ago

The Democratic contract at 67¢ shows extreme asymmetric risk, with the "No" side offering a 368.7% implied yield compared to just 89.4% for "Yes," suggesting significant underpricing of Republican chances despite the current Democratic lean. With zero 24-hour volume but $12.3M open interest and a 9¢ spread, this market suffers from severe illiquidity that likely explains the distorted yields and 396% realized volatility. The 201-day timeframe to the November 2026 election provides ample time for price discovery, but the current 4.12 volatility ratio and 2.0 info arrivals per hour indicate this market remains highly uncertain and potentially mispriced.
