Kalshi
In a 3-ball golf competition format, three golfers compete together during the first round of the 2026 U.S. Open. The golfer with the lowest score for the round wins the 3-ball matchup. This market resolves based on which of the three competitors—Nicolai Hojgaard, Nicolas Echavarria, or Robert MacIntyre—posts the best score.
The winner of the 3-ball matchup is determined by the lowest score posted during the first round of the 2026 U.S. Open. If two or more participants tie for the lowest score, the Yes payout is divided equally among all tied participants, with each receiving $1/N rounded down to the nearest cent, where N equals the number of tied participants. The No payout equals $1 minus the Yes payout. If any golfer withdraws before teeing off, all markets resolve to fair market value.
Prediction market odds and traditional sportsbook odds often diverge because they reflect different participant bases and incentive structures. Sportsbooks set lines to balance action and protect their margins, while prediction markets like this one are driven by trader consensus on actual outcomes. Comparing this market's odds to major sportsbooks can reveal where informed traders see value or disagreement. Many bettors monitor both venues to identify mispricings, though each operates independently with distinct liquidity and pricing mechanisms.
On Kalshi, this market is priced through continuous order-book trading, where buyers and sellers submit bids and offers that determine the real-time probability for each player in the 3-Ball grouping. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders stake capital on their belief about who will perform best in the first round, and the market price reflects the collective confidence of all active participants. As new information emerges—player form, course conditions, or injury reports—the price adjusts to reflect updated expectations.
This market resolves around Jun 18, 2026, once the first round of the tournament concludes and results are verified against credible public sources. The outcome is determined by the actual performance of Hojgaard, Echavarria, and MacIntyre during their 3-Ball grouping, with the winner or winning outcome confirmed through official tournament records. Resolution typically occurs within hours of the final putt in the first round.
Several catalysts can shift odds in this market before the tournament begins. Injury announcements, recent tournament results, or changes in player form will prompt traders to reassess probabilities. Weather forecasts for the course, equipment changes, or caddie updates may also influence pricing. As the start date approaches, any news about course conditions or field adjustments could trigger volatility. On tournament day itself, early round scores from other groups and real-time performance data will drive continuous repricing until the 3-Ball completes play.
