Analysis

This probability represents whether Bryce Harper will advance past the first round of the 2026 MLB Home Run Derby competition. At 39%, the market suggests Harper has less than even odds of qualifying for Round 2. Harper's performance depends on his health status heading into the Derby, his current home run hitting form during the 2026 season, and whether he receives an invitation to participate. The contract shows lower confidence compared to elite sluggers like Kyle Schwarber (72%) but notably higher than some other qualified hitters. The main catalyst will be the MLB's announcement of Derby participants, typically made shortly before the All-Star Game in early July. Harper's first-round matchup result would provide the definitive resolution, as Derby advancement is determined by raw performance in that specific event rather than season statistics.

  • Harper's cumulative home run total and batting average through late June 2026 season, which indicates current form and power-hitting capability
  • Whether Harper receives an official Derby invitation and accepts participation, as non-participation would prevent Round 2 qualification
  • Harper's injury history and physical conditioning status in the weeks leading up to the Derby competition
  • The specific first-round matchup difficulty, as Harper's advancement depends on out-hitting his randomly assigned opponent in head-to-head competition
  • Historical Derby performance data for Harper in previous years, showing consistency or volatility in derby-specific performance versus regular season power

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.
