This is a market to predict who will win a men's tennis Calendar Grand Slam in 2026. This market resolves to the single male player who wins the Men’s Singles titles at all four Grand Slam tournaments in 2026. The relevant 2026 Grand Slams are the Men’s Singles tournaments in the 2026 Australian Open, French Open, U.S. Open, and Wimbledon. For the purpose of this market, a tournament victory is valid regardless of whether the final was won via a walkover, a mid-match retirement, or a standard completed match. If at any point it becomes impossible for a listed player to achieve a Calendar Grand Slam in 2026 (e.g. Alcaraz does not win the 2026 Australian Open) this market will resolve immediately to "No". If at any point it becomes impossible for any listed player to achieve a Calendar Grand Slam in 2026 (e.g. Alcaraz wins the 2026 Australian Open but loses in the first round of 2026 French Open) this market will resolve immediately to "None". Otherwise, this market will resolve when the results of the final 2026 Grand Slam are official. If any of the 2026 Grand Slam Men’s Singles Tournaments are cancelled, postponed after December 31, 2026 11:59 PM ET, or there is otherwise no winner declared within that timeframe, this market will resolve to “None”. The primary resolution source for this market will be information from the organizers of the Grand Slam tournaments; however, a consensus of credible reporting may also be used.
