Tracks the leading outcome in a winner-take-all prediction market set with 4 outcomes.

Why this matters:
This market estimates a 5% probability that Jackson Koivun will win at least one major golf championship in the next decade. Koivun is a professional golfer whose odds reflect the extreme difficulty of winning major tournaments—only a small fraction of players on tour ever achieve this milestone. The current pricing suggests skepticism about whether he will reach the professional level needed to consistently compete for majors, or if he does, whether he'll breakthrough against the world's elite players. Uncertainty would be resolved through his performance trajectory on professional tours, his ability to compete in major championship fields, and ultimately whether he secures at least one title before 2036. Major championships occur annually across four events (Masters, U.S. Open, Open Championship, and PGA Championship).

Key factors:
- Jackson Koivun's current playing status and tour ranking relative to major-championship-qualifying thresholds
- Historical base rate of PGA Tour players ever winning a major championship (approximately 2-3% of players who make the tour)
- Koivun's performance record in high-level amateur and professional competitions, including major championship invitational access
- Competitive depth in professional golf and the concentration of major wins among elite-tier players
- Time remaining until 2036 and whether Koivun remains active as a professional golfer through the period

## 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.
