Texas Republican Senate runoff: which counties will Ken Paxton win?

Prediction market odds on Kalshi often diverge from traditional polling because markets incorporate real-money incentives and continuous price discovery. While polls measure voter sentiment at a single moment, prediction markets aggregate ongoing trader bets and evolve as new information emerges. For the Texas Republican Senate runoff, market odds may reflect campaign developments, turnout expectations, and county-level dynamics that polls capture less dynamically. Comparing the two reveals whether traders are more or less confident than pollsters about Paxton's county-level performance, offering a complementary lens on the race.

The market resolves on Nov 3, 2026. Resolution is determined by official election results for each county in the Texas Republican Senate runoff. Once the runoff election concludes and results are certified, each county outcome contract settles based on whether Ken Paxton won that specific county. Traders who correctly predicted the outcome receive their payout, while incorrect positions expire worthless. The resolution process relies on authoritative electoral data to determine which counties Paxton carried.

Key catalysts include campaign announcements, debate performances, and endorsements that shift voter sentiment in specific counties. Early voting and turnout data from key regions can signal which areas Paxton is mobilizing. Polling releases focused on county-level or regional breakdowns often trigger repricing. Demographic shifts, local news coverage, and candidate spending in particular counties may influence trader expectations. Unexpected controversies or strategic pivots by either campaign could reshape county-level dynamics. As election day approaches, actual early voting results and final pre-election surveys typically drive the most significant price movements.
