Tracks the leading outcome in a winner-take-all prediction market set with 2 outcomes.

Why this matters:
This probability represents the combined chances that Spencer Pratt wins the 2026 Los Angeles mayoral race while Tom Steyer wins California's gubernatorial race. At 52%, this outcome currently leads the multi-outcome market, though it reflects the highest probability among five possible candidate pairings. The market is pricing in several dynamics: Karen Bass and Xavier Becerra together command identical probability (52%), suggesting uncertainty about whether voters will consolidate around incumbent leadership or seek change. Xavier Becerra appears in the two highest-probability scenarios (58¢ combined across his two pairings), indicating market confidence in his gubernatorial prospects. The resolution hinges on both races moving forward simultaneously through California's election cycle. Upcoming primary dates, candidate announcements, and polling data through fall 2026 will test whether these probabilities hold or shift as voter preferences crystallize.

Key factors:
- Xavier Becerra appears in 58¢ of total market probability across two contracts, suggesting stronger consensus around his gubernatorial viability than Steyer
- Karen Bass-Xavier Becerra pairing matches the Spencer Pratt-Tom Steyer price at 52¢, indicating near-equal probability for incumbent vs. alternative slates
- Spencer Pratt and Nithya Raman combined account for only 18¢ across mayoral pairings, suggesting market skepticism about anti-incumbent momentum in Los Angeles
- Tom Steyer appears in only 8¢ of total probability across two contracts, indicating lower market confidence in his gubernatorial prospects versus Becerra
- Daily trading volume exceeds $800 on the leading contracts but drops below $300 on lower-probability outcomes, showing concentrated trader attention on two main scenarios

## 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.
