Analysis

This probability reflects the leading contract's assessment that a specific team will qualify for the Major League Baseball playoffs in 2026, currently priced at 90 cents. The high probability suggests either a commanding division position or strong remaining schedule relative to competitors. Movement in this market would depend on actual win-loss records over the remainder of the regular season, as teams compete for limited playoff spots through direct standings races and wild-card positions. The primary catalyst driving resolution is the MLB regular season's conclusion on October 4, 2026, when final standings determine which teams clinch playoff berths. Between now and then, head-to-head matchups against division rivals, performance against teams in similar win totals, and injury developments to key players will incrementally shift win probabilities and thus playoff qualification odds.

  • Current standings position and games remaining relative to other contenders in the same division or wild-card tier as of July 2, 2026
  • Strength of schedule for the leading team versus direct competitors through the regular season's end
  • Historical correlation between early-season performance (after 81+ games played) and final playoff qualification outcomes
  • Trade deadline activity and roster changes that materially alter team composition before the July 31 deadline
  • Injury status of All-Star or core roster players affecting win probability over the final three months

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.
