Analysis

This 28% probability indicates traders assess a roughly one-in-four chance that Speaker Mike Johnson loses his position before a specified date. The forecast reflects ongoing political fragmentation in the House, where Johnson has faced pressure from both moderate Republicans seeking compromise on spending and conservatives demanding ideological purity. His narrow majority and previous challenges securing votes on key legislation have created vulnerability. The probability would likely rise if major policy votes fail, if a significant bloc of Republicans formally calls for his ouster, or if party leadership signals reduced support. The primary driver of resolution will be whether House Republicans can maintain cohesion through the remainder of 2026, particularly around budget negotiations and any leadership challenges that emerge during campaign season.

  • Johnson's razor-thin majority requires near-unanimous Republican support on contentious votes, making defections a recurring risk factor
  • Historical precedent: three Speakers have been removed via motion to vacate since 2015, establishing that removal is a viable political tool
  • The timing of major fiscal deadlines and appropriations negotiations in late 2026 will test party unity and generate leverage for potential challengers
  • Midterm campaign dynamics may create incentives for factional challenges if party performance appears weak or if primary battles emerge
  • Current market pricing at 28% versus 19% on Polymarket suggests modest disagreement about removal probability across trading venues

Lateral coverage

Thin contract — here's where the deeper coverage is.

This page aggregates 2 contracts (32% headline). At low contract count, the price reflects two participants’ opinions, not a market consensus. The links below are heavier related questions where the orderbook signal is real.

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.
