Why this matters:
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.

Key factors:
- 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
