Trader consensus overwhelmingly favors "None" at 85.5% implied probability for a men's calendar Grand Slam in 2026, reflecting the event's extreme rarity—last achieved by Rod Laver in 1969—despite Carlos Alcaraz's dominant Australian Open triumph over Novak Djokovic in February, marking his first hard-court major and completing a career Grand Slam at age 22. Alcaraz's 11.2% share acknowledges his versatility across surfaces, prior French Open and Wimbledon titles, and world No. 1 status, but traders price in the grueling path ahead: clay-court French Open (late May), grass Wimbledon (July), and hard-court US Open (August-September), amid fatigue risks, injury concerns, and stiff competition from Jannik Sinner and Djokovic. A challenge would require Alcaraz sustaining peak form without withdrawals, major upsets, or physical breakdowns through three demanding majors.

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 anyone to achieve a Calendar Grand Slam in 2026 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.
