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

Why this matters:
This probability represents the likelihood that both Ohio's gubernatorial and Senate races in 2026 will be won by Republicans—specifically Vivek Ramaswamy for governor and Jon Husted for Senate. At 45%, this reflects a competitive but Republican-favored scenario according to current market pricing. The probability is primarily driven by broader partisan lean in Ohio and candidate-specific factors like incumbent advantages or approval ratings. The Democratic-sweep scenario (38%) remains nearly as likely, suggesting tight races where either party could dominate both contests. Key uncertainties include campaign dynamics, turnout patterns, and any major developments affecting the lead candidates through November 2026. Election Day on November 3, 2026, will definitively resolve all outcomes.

Key factors:
- Republican lean in Ohio: Recent statewide elections show the state trending Republican, which would support this joint Republican outcome over Democratic sweeps
- Incumbency and candidate positioning: Jon Husted's current status and Vivek Ramaswamy's profile relative to Democratic challengers Amy Acton and Sherrod Brown materially affect both races
- Market disaggregation: The 38% probability of Democratic sweep versus 45% Republican sweep indicates markets view these races as genuinely competitive rather than predetermined
- Low trading volume on Kalshi: Minimal 24-hour volume on most contracts suggests limited recent price movement, potentially reflecting stable but uncertain expectations
- Split-ticket potential: The 7% and 9% probabilities for mixed outcomes show markets assign meaningful probability to voters supporting candidates across party lines in one race

## 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.
