Scottie Scheffler's performance on individual holes during the third round of the 2026 U.S. Open will be tracked across all 18 holes. For each hole, bettors predict whether he will score birdie or better (below par), even par, or bogey or worse (above par) relative to that hole's par.
Each hole in Round 3 is evaluated independently based on Scottie Scheffler's score relative to par. Scores are measured on a relative scale where lower (more negative) scores represent better performance. Birdie or better includes any score below par (e.g., -1, -2, etc.), even par (E) represents a score equal to par, and bogey or worse includes any score above par (e.g., +1, +2, etc.). For each of the 18 holes, the player's actual hole score determines which outcome category applies, and the corresponding market resolves to Yes if that outcome occurs.
Prediction market odds and sportsbook odds often diverge because they reflect different pricing mechanisms. Sportsbooks set lines to balance liability and extract a margin, while prediction markets like this one are priced by traders competing to profit on their forecasts. Prediction markets tend to incorporate real-time information faster and reward accurate forecasters, which can make them more responsive to breaking news or late-developing conditions. However, sportsbooks benefit from professional oddsmakers and large historical datasets. Comparing the two can reveal where consensus differs and highlight potential value in either venue.
On Kalshi, this market is priced through a continuous order-book mechanism where traders submit bids and asks for each outcome. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each outcome reflects the aggregate willingness of traders to buy or sell at that level, updating in real time as new orders arrive and existing ones are filled. Prices range from near-zero to near-100 cents per share, with the spread between bid and ask tightening as liquidity increases. This mechanism rewards traders who identify mispriced outcomes and encourages efficient price discovery as new information enters the market.
This market resolves around Jun 22, 2026, once Round 3 of the event concludes and hole-by-hole scoring is finalized. The outcome is confirmed when the data becomes verifiable from credible public sources covering the tournament. Until that point, traders can continue to buy and sell shares based on their forecasts of the final scores. Resolution occurs automatically once the event is complete and the scoring is official, at which time all open positions settle according to the actual results.
Several factors can shift prices in this market before resolution. Real-time scoring updates during Round 3 will trigger immediate repricing as each hole is completed. Weather changes, course setup modifications, or unexpected player performance swings can alter expectations significantly. Leaderboard position shifts and commentary from broadcasters or analysts may influence trader sentiment. Injury reports or equipment issues affecting Scheffler could also move odds. Early rounds' results and historical hole-by-hole patterns provide context, but live action during Round 3 itself typically drives the most dramatic price movements as uncertainty resolves.
