Tracks the leading outcome in a winner-take-all prediction market set with 3 outcomes.

Why this matters:
This market is pricing in a 54% probability that Democrats will hold a significant governorship advantage after the 2026 midterm elections, with a near-zero chance of an exact tie. Currently, Democrats control 27 governorships and Republicans control 23, giving Democrats a +4 advantage. The market's lean toward Democratic gains reflects expectations about which seats are competitive this cycle. The main drivers are the number of Republican-held seats in purple or lean-Democratic states versus Democratic-held seats in lean-Republican territory. The November 2026 general election will directly resolve this outcome, with results determining the final governorship count and the numerical difference between the parties.

Key factors:
- Current seat count: 27 Democratic governors vs. 23 Republican governors (+4 Democratic advantage)
- Competitive races identified in purple states like Arizona, Nevada, and Pennsylvania where seat control could shift
- Structural factors including the party distribution of governorships expiring in 2026 and each state's electoral lean
- Historical midterm patterns showing whether the party holding the presidency gains or loses gubernatorial seats
- Early polling and fundraising data for individual governorship races in the most competitive states

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.
