Kalshi
This market determines the winner of a 3-ball golf competition featuring Max Greyserman, Jacob Bridgeman, and Brian Harman during the first round of the 2026 U.S. Open. The golfer with the lowest score at the end of the round wins the matchup.
The winner of the 3-ball matchup is determined by the lowest score at the end of the round. If multiple participants tie for the lowest score, each tied participant receives an equal share of the Yes payout, calculated as $1 divided by the number of tied participants and rounded down to the nearest cent, with the No payout adjusted accordingly. If any golfer withdraws prior to teeing off, all markets resolve to fair market value.
Prediction market odds and sportsbook odds often diverge because they reflect different pricing mechanisms and participant bases. Sportsbooks set odds to balance liability and generate profit margins, while prediction markets like this one are priced by traders seeking to profit from accurate forecasts. Prediction markets tend to incorporate dispersed information and real-time sentiment more dynamically, sometimes leading to sharper or earlier adjustments than traditional sportsbooks. Both venues can offer valuable signals, but prediction market pricing is often viewed as a purer reflection of crowd belief about the outcome.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares representing different outcomes. 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 balance of supply and demand; as more traders believe in a particular result, its price typically rises. Traders can place limit or market orders to enter or exit positions, and the spread between bid and ask prices represents the current liquidity and conviction gap. This continuous auction process ensures prices adapt in real time to new information and shifting expectations.
This market resolves around Jun 18, 2026, once the event concludes and the result is verifiable from credible public reporting. The outcome will be confirmed based on the official result of the 3-Ball match involving the specified competitors. Until that point, traders can continue to adjust positions as conditions change and new developments emerge. Resolution timing may shift slightly depending on when final confirmation becomes available through authoritative sources.
Several factors could shift pricing in this market before resolution. Announcements regarding competitor form, recent performance, or head-to-head records may trigger repricing as traders update their expectations. Changes in match conditions, venue details, or any official updates about the event format could also influence sentiment. Media coverage, expert commentary, and early-round results from related competitions may provide new information that traders incorporate into their positions. As the event date approaches, increased trading activity and refined forecasts typically lead to tighter odds and sharper price discovery.
