Will John Cornyn be the Republican nominee for the Senate in Texas?

The market is pricing Cornyn's nomination chances at a significant discount to Polymarket (38¢ vs 40¢), suggesting potential arbitrage opportunity or venue-specific liquidity effects, though the 2¢ gap is modest relative to the tight 1¢ spread. The extraordinarily high implied yield on the Yes side (313.5%) reflects the low absolute price and extended 198-day timeframe, but this is mechanically inflated rather than indicative of unusual opportunity given the neutral regime and moderate realized volatility of 174%. With $1.1M open interest against just $4.5K daily volume, liquidity is concentrated and the market appears to be pricing Cornyn as a clear underdog despite his incumbent status, warranting scrutiny of recent political developments driving the 7-day decline from 38¢ to 37¢.

Resolution rules

If John Cornyn wins the nomination for the Republican Party to contest the 2026 Class II Texas Senate seat, then the market resolves to Yes.
