Analysis

This probability reflects trader expectations that the Associated Press will call a House majority winner before midnight ET on November 4, 2026—roughly one day after election day. The high probability (97%) suggests confidence that major news organizations will declare a winner quickly, as has been typical in recent cycles when one party gains a decisive advantage. Two factors drive this assessment: historical precedent (the AP called the 2022 House majority within hours of polls closing) and current polling showing potential blowouts in either direction, which would accelerate a call. However, a closely divided chamber would delay the call, potentially past Nov 4. The specific catalyst is election night itself on November 3-4, when sufficient races will be decided to determine which party controls the chamber. Traders are pricing in roughly a 40% chance the call comes before Nov 4 midnight specifically, versus higher odds it arrives by early November 6.

  • Historical AP behavior: 2022 House majority was called within 24-48 hours; 2020 took four days due to closer margins
  • Current polling aggregates and generic ballot trends suggest either a significant Republican or Democratic advantage, which would enable quicker AP confidence in a call
  • The tiered contract structure (57% before Nov 4, 87% before Nov 6) shows traders expect most of the remaining uncertainty to resolve within a ~48-hour window after polls close
  • AP call timing depends on outstanding races and margin thresholds, not on official results; uncertainty remains around which races stay too close to project
  • Zero volume on top contracts in past 24 hours indicates this is priced but not actively traded, suggesting limited recent information flow

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.
