Contract brief

The Texas Senate Republican primary runoff election is scheduled for May 26, 2026. This market will resolve according to the margin of victory between the top two candidates in the Texas Republican Senate Primary runoff election. For the purpose of this market, the “margin of victory” is defined as the absolute difference between the percentages of valid votes received by the first- and second-place candidates. Percentages of the valid votes received by each candidate will be determined by dividing the total number of valid votes each of the top two candidates receives by the sum of all valid votes cast in the election. If the reported value falls exactly between two brackets, then this market will resolve to the higher placed bracket (ascending). If two candidates receive the same number of valid votes, this market will resolve according to the candidate whose last name comes first alphabetically. This market will resolve based on the official vote count once the count has been made official. If the results of the specified election are not known definitively by November 30, 2026, 11:59 PM ET, this market will resolve to “Other”. The primary resolution source for this market will be information from the State of Texas, such as official statewide results published by the Texas Secretary of State (https://elections.sos.state.tx.us/index.htm); however, an overwhelming consensus of credible reporting may suffice. If a recount is initiated before the vote total has been made official, the market will remain open until the recount is completed and the vote is made official.

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.
