Tracks the leading outcome in a winner-take-all prediction market set with 9 outcomes.

Why this matters:
Markets estimate a 68% probability that the longest home run at the 2026 Home Run Derby will exceed 485 feet. The Home Run Derby typically features elite power hitters competing under conditions favorable to distance—a controlled environment with optimized balls and bats that often produce longer distances than regular-season games. The probability reflects historical precedent: recent derbies have regularly seen 480+ foot shots, though exceeding this threshold consistently depends on participant quality and weather conditions. The event is scheduled for summer 2026, and the outcome will be definitively measured and publicly reported. Notable uncertainty remains in the upper tiers: only 39% probability of 500+ feet and just 3% of 525+ feet, suggesting markets expect competitive but not historically extreme distances.

Key factors:
- Historical Home Run Derby records show the longest hit has exceeded 480 feet in most years since 2015, establishing a baseline for the 485-foot threshold
- Participant selection and power-hitter talent pool in 2026 will directly influence maximum distance; elite competitors like Juan Soto or Kyle Schwarber significantly raise probability versus a weaker field
- The contract pricing ladder (68% for 485+, 39% for 500+, 16% for 515+) shows markets assign roughly 30-point probability drops per 15-foot increment, indicating normal distribution assumptions
- Environmental factors including stadium elevation, wind conditions, and weather on derby day could shift outcomes by 20-30 feet but are not yet determined
- The specific 485-foot threshold appears chosen as slightly above the recent historical median rather than an extreme outlier, making it the consensus likely outcome

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.

## SF Signal

- SF Index, regime, and 30d Brier calibration are computed separately and surfaced at https://simplefunctions.dev/admin/calibration.
- No SimpleFunctions index / regime / calibration signal is bound to this topic yet — the headline above is market-derived only.
