Tracks the leading outcome in a winner-take-all prediction market set with 4 outcomes.

Why this matters:
This contract asks whether Democrats will win more than 49 seats in California's 2026 House elections. At 43%, the market implies Democrats are slightly more likely to fall at or below 49 seats than exceed it. California's House delegation has trended Democratic in recent cycles, and Democrats currently hold most of the state's districts. The outcome depends primarily on national midterm dynamics, turnout patterns, and candidate quality in competitive districts. The main uncertainty driver is how strongly or weakly Democrats perform nationwide in 2026—a strong national performance would likely push them above 49 California seats, while significant losses would keep them at or below that threshold. Results will be determined on election day, November 3, 2026.

Key factors:
- Democrats currently hold approximately 43 of California's 52 House seats, meaning they need net gains in an already-controlled state to exceed 49 seats
- The 43% probability implies the market views sub-50 Democratic seats as a modestly more likely outcome than above 50, suggesting expectations of modest net losses or minimal gains
- National House performance in 2026 midterms will be a primary driver—strong Democratic national results would likely lift California above 49, while major losses would depress it below
- California's electoral composition and voter registration patterns have become increasingly Democratic-leaning, which could support maintaining or growing the current delegation
- Redistricting effects from the 2020 census are now fixed in place, removing that source of uncertainty and locking in the competitive landscape for this election cycle
