Analysis

This probability estimates the likelihood that Roch Cholowsky will play in an MLB game before August 1, 2029—roughly three years from now. The 92% price reflects confidence he'll reach the majors within this timeframe, though the declining odds across earlier deadlines (68% for May 2029, 69% for November 2029) suggest uncertainty about the specific timing of his debut. Key drivers include his current minor league trajectory, development pace, and team roster decisions. The most immediate catalyst would be any official call-up or sustained demotion that clarifies his pathway to MLB play. The gap between the August 2029 contract (92%) and May 2029 (68%) indicates traders expect his debut more likely in the second half of 2029 than the first half.

  • Current status and organizational depth: Whether Cholowsky is trending toward or away from MLB readiness in his team's developmental pipeline
  • Injury history and performance trends: Any recent injuries, rehab assignments, or sustained performance slumps that would delay or accelerate a call-up
  • Roster turnover and competitive window: Whether his team will have roster space and motivation to promote him by the deadline
  • Minor league statistics and recent promotions: Concrete performance data showing progression through successive minor league levels
  • Official team statements or roster moves: Any public indication of call-up timing or organizational plans for his development

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.
