Trader consensus overwhelmingly favors "None" at 99.5% for a men's Calendar Grand Slam in 2026, reflecting the historical rarity—no player has achieved it since Rod Laver in 1969—and Carlos Alcaraz's recent right wrist injury that forced his withdrawal from the French Open, the next required major after his Australian Open triumph. Alcaraz, the youngest to complete a Career Grand Slam with his AO title over Djokovic, reached the Monte Carlo final before the Barcelona setback sidelined him from Madrid, Rome, and Roland Garros. No other player holds the AO win needed to pursue the sweep, cementing the near-impossibility. A dramatic recovery and late FO entry could theoretically revive faint 0.1% Alcaraz odds, but official medical clearance appears unlikely amid swelling concerns.
