Analysis

Markets are pricing a 96% probability that Missouri will redistrict before the 2026 Congressional elections, with Texas and Florida also showing high probabilities (96% and 94% respectively). Congressional redistricting typically occurs after decennial censuses, but special circumstances can trigger mid-decade changes—primarily when courts order them due to constitutional violations or when state legislatures voluntarily pursue them for political advantage. The high probability reflects expectations that at least one of these states will undergo redistricting before November 2026. Key drivers include recent court decisions on existing maps, litigation timelines, and legislative willingness to act. Resolution depends on whether any redistricting plan is officially adopted and implemented by Election Day 2026, which would determine which contracts settle affirmatively versus void.

  • Missouri has faced ongoing litigation over congressional maps; recent court rulings or settlement agreements would indicate redistricting likelihood
  • Texas and Florida show nearly identical high probabilities, suggesting market belief that at least one major state will redistrict rather than each individually having 96% odds
  • The 18-contract structure means exactly one state's outcome will be selected; if multiple states actually redistrict, only the designated winner settles
  • Upcoming state legislative sessions or court decision dates in 2026 would provide concrete catalysts that could shift these probabilities significantly
  • Historical pattern: mid-decade redistricting remains uncommon; most occur following census reapportionment in years ending in '01

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.
