Why this matters:
This probability indicates that markets currently assess Team Europe as a 32% favorite to win the upcoming Ryder Cup, compared to a 66% probability for Team USA and a 2% chance of a tie. The disparity reflects Team USA's recent dominance in the competition, having won four of the last five Ryder Cups. Team Europe's probability depends on factors including current world golf rankings of both teams' rosters, recent performance in major tournaments, and home-course advantage if the venue favors European playing conditions. The Ryder Cup itself, scheduled for September 2026, serves as the key catalyst that will definitively resolve this market. Until then, movements in the probability may reflect roster announcements, captain selections, injuries to key players, or shifts in momentum from intervening PGA Tour and European tour events.

Key factors:
- Team USA has won 4 of the last 5 Ryder Cups (2016 loss to Europe, wins in 2018, 2021, 2023, 2025)
- Current world ranking distribution of eligible players on each team roster and recent major championship performance
- 2026 Ryder Cup venue location and whether course conditions historically favor American or European playing styles
- Player availability and injury status for both teams as September 2026 approaches
- Captaincy selections and recent team chemistry based on preceding tour events in summer 2026

## 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.
