Analysis

4d ago

This market shows extreme yield asymmetry with Yes traders earning 210.5% annualized versus 38.7% for No, suggesting significant underpricing of a narrow Paxton victory despite Texas's Republican lean. The modest $6.5K open interest and $177 daily volume indicate thin liquidity that could amplify price swings, particularly as the 405-day expiration approaches and the 2026 race becomes more concrete. The recent 4-cent rally from 26¢ to 30¢ combined with a tight 3-cent spread hints at growing conviction among Yes backers, though the neutral regime score (0.409) suggests the market hasn't yet reached consensus on whether a close race is likely.

Resolution rules

If the margin of victory for Ken Paxton in the 2026 Texas Republican Senate runoff falls between 0% and 5%, inclusive of its lower bound and exclusive of its upper bound, then the market resolves to Yes.
