Leader: Ken Paxton at 96% · Polymarket 96% · 2 contracts · $120K volume · medium confidence
Updated 2026-06-08 08:45:30 UTC

Tracks the leading outcome in a winner-take-all prediction market set with 2 outcomes.

Why this matters:
Ken Paxton holds a 57% probability of winning the Texas Republican Senate primary, reflecting moderately favorable odds among prediction market participants. This probability suggests genuine uncertainty, with Cornyn at 43% representing a meaningful competitive threat. The outcome hinges on voter appetite for Paxton's record as Attorney General versus any concerns about his prior legal challenges, combined with campaign organization and endorsement dynamics heading into the primary. National political dynamics, fundraising reports, and polling data closer to the election will likely shift these odds, as will any significant candidate developments or endorsements from Texas Republican leadership. The primary election date will be the decisive catalyst, providing the definitive outcome and resolving current market positioning.

Key factors:
- Paxton's current Attorney General tenure and approval rating among Texas Republicans versus Cornyn's prior Senate service and establishment backing
- Fundraising totals and cash-on-hand figures for both candidates as reported through FEC filings
- Public polling of the Texas Republican primary matchup released in the months preceding the election
- Endorsement patterns from major Texas Republican figures, party leadership, and national Republican organizations
- Voter turnout levels and demographic composition in the actual primary election relative to historical patterns

Contracts:
- Texas Republican Senate Primary Winner: Ken Paxton — 96¢ Polymarket $88K (weight 73%)
- Texas Republican Senate Primary Winner: John Cornyn — 4¢ Polymarket $32K (weight 27%)

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.
