Carlos Alcaraz's recent withdrawal from the 2026 French Open, confirmed in updated Roland Garros entry lists, has cemented trader consensus at 99.5% for "None" achieving a calendar Grand Slam, as his Australian Open triumph in February—defeating Novak Djokovic 2-6, 6-2, 6-3, 7-5 to complete a career Grand Slam at age 22—was the only path forward, with no other player able to sweep all four majors. The inherent challenges of transitioning from hard courts to clay, grass, and back to hard, compounded by injury risks and historical precedent—no men's calendar Slam in the Open Era—drive this lopsided pricing. Alcaraz lingers at 0.1% on slim odds of a last-minute reinstatement, though official lists exclude him amid Jannik Sinner's emergence as French Open favorite.
