Analysis

This market assesses whether MLB Home Run Derby participants will hit at least two balls 500+ feet during the 2026 event. At 38%, it suggests the outcome is somewhat unlikely but not remote. The probability reflects historical data on ultra-distance home runs in derby conditions—500+ foot homers are exceptionally rare even among elite power hitters swinging in a competition designed to maximize distance. Factors driving this level include the quality of participating hitters, ballpark dimensions, and weather conditions on event day. The 2026 MLB Home Run Derby, scheduled for mid-July, will provide the definitive measurement. Current pricing shows higher confidence in at least one 500+ footer occurring (30¢) versus two or more (11¢), suggesting markets view incremental distance thresholds as increasingly difficult to clear. The gap between these contracts indicates meaningful uncertainty about extreme power output sustainability across multiple swings.

  • Historical frequency: 500+ foot home runs in recent MLB Home Run Derbies occur in single digits or not at all, establishing a baseline for rarity
  • Participant pool composition: The specific hitters selected for 2026 will determine average exit velocity and power ceiling; elite sluggers increase probability substantially
  • Ballpark choice impact: Venue selection affects both baseline distance and whether atmospheric/dimensional factors favor extreme distance outcomes
  • Measurement standards: Official Statcast or equivalent tracking technology must verify and classify each homer, introducing potential definitional variance
  • Recent trend data: 2024-2025 derby results and aggregate exit velocities among current MLB power leaders provide the most recent comparable sample

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.
