Contract brief

This market will resolve according to the team that wins the 2026 MLB World Series.

If the 2026 MLB season is cancelled, postponed after December 31, 2026 ET, or there is otherwise no winner declared within that timeframe, this market will resolve to “Other”. The primary resolution source will be official information from MLB (https://www.mlb.com/); however, a consensus of credible reporting may also be used.

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
