Carlos Alcaraz's wrist injury, sustained in April at the Barcelona Open and sidelining the world No. 2 since then, has created a closely balanced market at 52.5% implied probability for his US Open appearance. The defending champion remains on the official entry list for the hard-court Grand Slam that begins August 31, yet his recent withdrawal from the Cincinnati Masters—coupled with limited training progress—has tempered expectations for a seamless return. Traders weigh his history of cautious recovery against the short timeline for regaining match fitness ahead of Flushing Meadows, with the Winston-Salem Open as a potential final tune-up. Confirmed medical clearance or a successful pre-tournament event could strengthen the case for participation, while any further setbacks would likely shift sentiment toward absence.
