Analysis
This 24% probability reflects market expectations that the Senate will pass a reconciliation bill before January 1, 2027, suggesting traders view passage as unlikely but plausible within the next six months. Reconciliation bills are rare legislative vehicles that require only 51 Senate votes rather than 60, making them strategically important for major legislation but difficult to construct due to strict budget rules and party divisions. The timing structure—with progressively lower prices for earlier deadlines (11% by September, 14% by October)—suggests traders expect delays if passage occurs at all. The primary drivers are current Senate composition, whether a reconciliation framework gains bipartisan support, and the procedural timeline required for markup and floor votes. The biggest near-term catalyst is the August recess, which would significantly compress the timeline for a September 1 resolution.
- ›Current Senate vote count and leadership commitment: 51 votes needed vs. 60-vote threshold for standard bills; recent budget resolution status indicates priority level
- ›Reconciliation scope and pay-for mechanisms: broader spending bills face higher failure risk due to PAYGO constraints and deficit concerns
- ›Legislative calendar constraints: Senate workdays available between now and January 1, 2027, with August recess reducing September deadline feasibility
- ›Party cohesion on spending priorities: defections within either party would delay or block passage
- ›External fiscal events: Congressional Budget Office scores and economic data that could shift priorities away from reconciliation in this period

Democrats Firming as Favorites to Hold House in 2026
Democrats have strengthened their position to retain control of the House of Representatives in the 2026 midterms, with contracts rising to 78¢. This shift comes amid strong fundraising and favorable special election results, challenging the historical midterm penalty for the president's party. The Senate race remains a toss-up, with Republicans at 57¢ to take control.
Democratic House Control Strongly Favored at 78¢
Traders are pricing in a 78% probability that Democrats will win control of the House in 2026, while the Senate remains a toss-up with Republicans at 57¢. This balance of power scenario is a key input for midterm election trading strategies.
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.
