Analysis

5d ago

This market prices J.D. Vance's 2028 Republican primary run at 77% probability with a notably asymmetric risk profile—the "No" side offers 166.3% annualized yield versus just 20.5% for "Yes," reflecting the market's confidence in a Vance candidacy but limited upside for believers. The 6¢ spread and thin $5 daily volume suggest low liquidity despite $11.6k open interest, and the recent 4¢ price decline over seven days may indicate slight erosion in conviction as we approach the 625-day deadline. With moderate cliff risk (3/10) and neutral regime conditions, this appears fairly priced for a frontrunner scenario, though the extreme yield skew warrants caution about tail risk assumptions.
