Analysis

This market estimates the probability that Ken Paxton wins Harris County in the 2026 Texas Republican Senate primary at 63%, based on pricing from multiple prediction contracts. The estimate reflects uncertainty about whether Paxton, the current Texas Attorney General, will secure victory in Texas's largest urban county during the Republican primary phase. Factors driving the current probability include Paxton's existing name recognition and political standing versus potential primary challengers, combined with Harris County's competitive electoral dynamics. The primary election itself will definitively resolve this market, as actual vote totals and county-level results become official. Between now and the election, polling data, campaign spending reports, endorsements, and primary debate performances could significantly shift expectations. Primary election day and subsequent official Harris County results certification represent the key catalyst that will determine the outcome.

  • Paxton's current approval ratings and name recognition among Harris County Republicans versus main primary competitors
  • Historical voting patterns in Harris County Republican primaries, including regional turnout and candidate performance trends
  • Official Harris County primary election results on election day, which will definitively resolve the market
  • Campaign spending and resource allocation in Harris County compared to challenger investments
  • Public polling data released before the primary showing candidate preference levels among Harris County GOP primary voters

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
