Jannik Sinner holds the 60 percent implied probability in this market largely because he captured the Australian Open title in January and enters the French Open period in strong physical condition after reaching the Rome Masters final. Carlos Alcaraz, by contrast, has been sidelined since mid-April with a right-wrist injury that forced withdrawals from the Italian Open and Roland Garros, leaving him without clay-court matches to build form ahead of the remaining majors. Sinner’s recent hard-court and clay results, combined with his ability to maintain depth and consistency across surfaces, have shifted trader sentiment toward the Italian securing at least two of the three leftover Grand Slams. Alcaraz’s potential return timeline for Wimbledon remains uncertain, further widening the gap in projected title counts for 2026.
