Tracks the leading outcome in a winner-take-all prediction market set with 5 outcomes.

Why this matters:
This represents the likelihood that professional tennis player Ben Shelton will sign an endorsement deal with Ralph Lauren specifically, rather than competing sportswear and apparel brands. The current 64% probability reflects market expectations that New Balance is the frontrunner partnership, based on patterns in professional athlete sponsorships and Shelton's existing endorsement portfolio. The probability could shift significantly if Shelton announces a major sponsorship agreement with any brand, or if new information emerges about his endorsement negotiations. Key drivers include his ranking trajectory on the professional tennis circuit, which affects sponsorship appeal, and the competitive dynamics among major athletic brands seeking to partner with rising players. The market's confidence level suggests traders view a New Balance deal as more probable than alternatives, though substantial uncertainty remains about the timing and specific partner.

Key factors:
- Ben Shelton's ATP ranking and performance trajectory directly influence which premium brands would prioritize sponsorship negotiations with him
- New Balance's recent tennis marketing investments and existing relationships with professional players create competitive positioning relative to other brands
- The absence of recent public announcements or confirmed negotiations with any brand creates information asymmetry that could shift probabilities upon disclosure
- Market volume is concentrated in New Balance contracts (zero 24-hour volume) versus Adidas (highest at $17), suggesting different trader confidence levels across brand outcomes
- Timing of any sponsorship announcement would resolve this contract, making nearness to typical athlete endorsement announcement windows a relevant factor

## 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.
