This market covers the professional tennis match between Johannus Monday and Giovanni Mpetshi Perricard in the 2026 ATP London Qualification Round 1 on June 14. Bettors predict the exact final set score of the match.
Resolution is based on the final set score of the match played in the 2026 ATP London Qualification Round 1. If the match does not commence due to injury, walkover, forfeiture, or cancellation before play begins, the market resolves to a fair price. Postponed or delayed matches remain open until the rescheduled match concludes within two weeks. If a player retires, markets that can be unconditionally settled based on completed play resolve accordingly; those that cannot are settled at Fair Market Price at the Exchange's discretion.
Prediction markets and sportsbooks price events differently because they serve different purposes. Sportsbooks set odds to balance their book and manage risk, often incorporating a built-in margin. Prediction markets like this one aggregate trader beliefs through continuous price discovery, where participants buy and sell shares based on their own conviction. This market reflects real-time consensus among predictors willing to stake capital on the exact score, whereas sportsbook lines are set by oddsmakers and adjusted primarily to manage liability rather than pure probability estimation.
On Kalshi, this market is priced through an order-book mechanism where traders submit bids and asks for each possible exact score outcome. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each outcome contract reflects the probability traders assign to that specific scoreline, with higher prices indicating greater perceived likelihood. As new information emerges or match conditions change, traders adjust their positions, and prices update continuously. You can enter limit or market orders to buy or sell shares at your desired price, and the market price at any moment represents the marginal trader's assessment of that outcome's probability.
This market resolves around Jun 14, 2026, once the Monday versus Mpetshi Perricard match concludes and the final score is verified against credible public sources. The outcome is determined by the exact final set and game score of the match. All winning shares are paid out based on which exact scoreline actually occurred, while all other outcomes expire worthless. Resolution typically occurs within hours of the match ending, pending confirmation of the official result.
Several factors can shift prices in this market before resolution. Recent form and head-to-head records between the players influence trader expectations about likely scorelines. Court surface, weather conditions, and tournament stage can all affect match dynamics and scoring patterns. Injury reports or player withdrawals would dramatically reprrice outcomes. Real-time match developments—such as early set results, momentum swings, or unexpected performance—typically cause sharp price movements as traders update their probability estimates. News about either player's fitness or mental state closer to match day may also trigger significant trading activity.
