Analysis

This represents the market's assessment that at least one Major League Baseball manager will be fired, resign, or otherwise depart before December 1, 2026—about 150 days from now. The 43% probability for A.J. Hinch reflects uncertainty around mid-season managerial changes, which typically occur when teams underperform or face organizational conflicts. The timing matters because we're currently in the 2026 regular season, so this period captures the remainder of the season through the playoffs and immediate offseason. The main drivers are current team performance relative to expectations, playoff positioning decisions, and any organizational instability. The biggest inflection point will be the trade deadline and subsequent playoff performance, which historically correlate with managerial changes.

  • A.J. Hinch's Houston Astros performance through the trade deadline and playoff push—teams typically make managerial changes if postseason hopes fade or internal conflict emerges
  • Year-to-date win-loss records and playoff probability for teams managed by the other candidates (Boone, Counsell, Butera, Albernaz) relative to organizational expectations
  • Historical baseline: MLB averages roughly 1-2 mid-season managerial changes per season, making a ~43% probability for a single manager within 5 months realistic but not heavily favored
  • Any reported front-office tensions, contract disputes, or public statements indicating job security concerns for listed managers
  • Playoff qualification thresholds for each manager's team—teams eliminated from contention are more likely to make leadership changes before October

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.
