Analysis

The 13% probability reflects market expectations that Contreras has roughly a 1-in-8 chance of winning the 2026 Home Run Derby. Contreras is a catcher with solid power credentials but faces competition from younger, prolific home run hitters like Kyle Schwarber (21% implied probability) and Junior Caminero (16%). Market participants appear to be pricing in both Contreras's demonstrated power and his position as a catcher, which typically limits at-bats and homer frequency compared to everyday position players. The outcome will be determined by the official Derby bracket announcement and participant selection, likely occurring in early July of the All-Star break period, combined with actual performance during the competition itself.

  • Contreras averaged 19 home runs per 162 games in recent seasons, below the rate of leading contenders like Schwarber, suggesting power is a limiting factor relative to peers
  • Catcher position typically correlates with fewer home runs per season than outfield or first base positions due to playing time constraints
  • Kyle Schwarber is priced at 21% despite being on a weaker team, indicating strong power metrics may outweigh team performance in Derby selection criteria
  • The Derby field size and selection criteria (commissioner's picks vs. earned spots) will directly determine Contreras's odds of participation and matchup difficulty
  • Recent seasons show Junior Caminero and Jac Caglianone at 12-16% despite being younger prospects, suggesting the market values trajectory and peak power ceiling alongside current production

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.
