Analysis

4d ago

This market exhibits extreme mispricing with a 3¢ price implying only 3% probability for a 6-9% margin victory, yet the Yes side offers an extraordinary 31,044.8% implied yield—suggesting either severe illiquidity or a significant analytical edge. The $13.4M open interest combined with minimal $10.13 daily volume and a wide 2¢ spread indicates this is a low-liquidity trap where the theoretical yield is largely illusory due to poor execution conditions. With 38 days to expiry and a cliff risk index of 32, the market is pricing in extreme tail risk, but the neutral regime score and recent price stability (2¢ to 3¢ movement) suggest this may reflect genuine uncertainty about whether a runoff even occurs rather than mispricing of the conditional probability.

Resolution rules

The Texas Senate Republican primary runoff election is scheduled for May 26, 2026. This market will resolve according to the margin of victory between the top two candidates in the Texas Republican Senate Primary runoff election. For the purpose of this market, the “margin of victory” is defined as the absolute difference between the percentages of valid votes received by the first- and second-place candidates. Percentages of the valid votes received by each candidate will be determined by dividing the total number of valid votes each of the top two candidates receives by the sum of all valid votes cast in the election. If the reported value falls exactly between two brackets, then this market will resolve to the higher placed bracket (ascending). If two candidates receive the same number of valid votes, this market will resolve according to the candidate whose last name comes first alphabetically. This market will resolve based on the official vote count once the count has been made official. If the results of the specified election are not known definitively by November 30, 2026, 11:59 PM ET, this market will resolve to “Other”. The primary resolution source for this market will be information from the State of Texas, such as official statewide results published by the Texas Secretary of State (https://elections.sos.state.tx.us/index.htm); however, an overwhelming consensus of credible reporting may suffice. If a recount is initiated before the vote total has been made official, the market will remain open until the recount is completed and the vote is made official.
