Analysis
This probability estimates a 30% chance that Bobby Witt Jr. will be selected for Major League Baseball's 2026 Home Run Derby, typically held during All-Star Week in July. Selection depends primarily on his mid-season performance metrics—particularly home run totals and batting average relative to other eligible players—and MLB's official selections announced closer to the event. The probability reflects uncertainty around whether Witt Jr.'s offensive production through June will warrant an invitation compared to other power hitters. The main catalyst resolving this question will be MLB's official Home Run Derby roster announcement, usually made in early to mid-July. Comparative contract pricing shows similar uncertainty across other candidates, with Aaron Judge trading at 4% and Max Muncy at 27%, suggesting markets view Witt Jr. as a moderate candidate relative to other sluggers.
- ›Bobby Witt Jr.'s home run count and slugging percentage through late June relative to other qualifying players
- ›MLB's historical selection criteria, which typically favor players with high home run totals and fan voting results
- ›Witt Jr.'s injury status and playing time availability heading into the All-Star break
- ›Competition from other power hitters—players like Judge, Muncy, and O'Neill Cruz may reduce selection likelihood if their offensive numbers exceed Witt Jr.'s
- ›Official Home Run Derby roster announcement date in early-to-mid July 2026, which definitively resolves the contract

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.
