Analysis

This contract represents the probability that Aaron Boone will be fired or resign as New York Yankees manager before September 1, 2026. At 12%, the market assigns this outcome low odds, reflecting Boone's established position with the organization and typical managerial tenure. The probability is primarily driven by the Yankees' regular-season performance through mid-August, as a significant collapse or unprecedented dysfunction could trigger front-office action. There's a notable 19-percentage-point gap between venues, with Polymarket pricing the scenario at 30% versus Kalshi's 11%, suggesting disagreement over either Boone's job security or the organization's tolerance for underperformance. The main catalyst would be the team's win-loss record and playoff positioning by late August, which would determine whether ownership considers managerial change necessary.

  • Yankees' winning percentage and playoff positioning as of August 2026, compared to historical standards for managerial dismissal mid-season
  • Presence or absence of publicly reported front-office disputes, player conflicts, or media narratives questioning Boone's authority or competence
  • Boone's contract terms and any buyout provisions that would affect owner willingness to make an in-season managerial change
  • Comparison to recent precedent: when other established MLB managers were removed mid-season and what circumstances triggered those decisions
  • Kalshi vs. Polymarket pricing discrepancy (11% vs. 30%), indicating either different interpretive models or one venue's potential mispricing

Lateral coverage

Thin contract — here's where the deeper coverage is.

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.
