Why this matters:
This market estimates a 6% chance that the Chicago White Sox and Los Angeles Dodgers will face each other in the 2026 World Series. The probability reflects that both teams would need to win their respective league championship series to meet in the finals. The Dodgers are currently favored to win the National League pennant at 29 cents, suggesting stronger playoff positioning, while the White Sox would need to overcome American League competition. The matchup probability depends on both teams' remaining regular season performance, playoff seeding, and injury status through October. Key developments include trade deadline acquisitions, winning streaks or slumps, and head-to-head records against other playoff contenders. The 2026 World Series in early November will ultimately resolve this market.

Key factors:
- Los Angeles Dodgers currently trading at 29 cents to win the 2026 World Series, indicating higher baseline win probability than Chicago
- Chicago White Sox playoff viability depends on American League competition intensity and whether they can secure a playoff spot
- Regular season standings and playoff seeding as of late September 2026 will determine each team's path to the championship series
- Injuries to key roster players on either team between now and October could significantly shift win probabilities
- Head-to-head performance and playoff history between these franchises shows mixed outcomes that don't strongly favor this specific matchup

## 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.
