What will Scottie Scheffler's Round 1 hole scores be at the 2026 Open Championship?

Prediction market odds and sportsbook odds often diverge because they reflect different trader bases and risk models. Sportsbooks set odds to balance their book and lock in profit margins, while prediction markets aggregate the collective beliefs of traders who profit by forecasting accurately. For golf events, sportsbooks may emphasize liability management on popular bets, whereas this market prices outcomes based on what traders genuinely believe will happen. Comparing the two can reveal where public perception differs from market consensus, though each serves a distinct purpose.

This market resolves around Jul 18, 2026, once Round 1 is complete and hole-by-hole scoring is finalized. The outcome for each hole is determined by Scheffler's actual score on that hole, verified against credible public sources including official tournament records and live scoring feeds. Each hole contract settles independently based on whether the outcome matches the prediction—for example, a birdie contract pays out if Scheffler scores one under par on that specific hole. Resolution is typically confirmed within hours of the round's conclusion.

Course conditions, weather forecasts, and Scheffler's recent form are key catalysts that shift prices before and during Round 1. Wind speed, rainfall, and green firmness affect scoring difficulty on each hole, prompting traders to adjust odds for birdies and bogeys. Live performance is the strongest signal—as Scheffler plays each hole, actual results immediately reprrice subsequent holes based on momentum, confidence, and remaining course conditions. Injury reports, equipment changes, or late-breaking news about the tournament setup can also trigger sharp moves. Traders monitor these signals continuously to stay ahead of price shifts.
