Analysis

This probability reflects the aggregate expected likelihood that one of the five listed MLB teams will qualify for the 2026 playoffs. At 94%, it indicates high certainty that at least one of these franchises will secure a postseason spot, though the specific winner remains uncertain across the contracts. The current season record, remaining games, and divisional standings drive this assessment. Teams with higher contract prices (Atlanta at 91¢, Cleveland at 39¢) are viewed as more likely playoff qualifiers, while lower-priced teams reflect increased competitive barriers. The primary catalyst determining outcomes will be regular-season performance through the end of October 2026, when the playoff field is finalized. Weather, injuries, and mid-season trades could materially shift individual team probabilities, though the aggregate 94% reflects confidence that the market's expectations of playoff qualification remain stable across this cohort.

  • Win-loss record and remaining schedule gap between each team and the playoff cutline as of early May 2026
  • Trading deadline activity (late July/early August) and whether teams add or subtract playoff-contending talent
  • Injury status of key roster players, particularly starting pitchers and offensive core contributors
  • Historical playoff qualification rates for teams at similar win-percentage levels with equivalent games remaining
  • Head-to-head competitive strength within divisions and wildcard positioning relative to other MLB conferences

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.
