## 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.

### Key factors

- 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

## Methodology

Headline is the **leader's price**, not an arithmetic mean — averaging disjoint winner-take-all outcomes is meaningless. Per-outcome prices come from the venue's last-traded mid; cross-venue values are simple means across contracts on each venue.
