Aryna Sabalenka enters the round of 16 as the clear market leader for a US Open semifinal berth, riding two prior titles and dominant hard-court results, though traders weigh her path against resurgent challengers. Coco Gauff carries strong momentum after her Cincinnati title and benefits from home support, while Iga Swiatek has regained form following her Toronto win. Elena Rybakina’s ankle concerns from Cincinnati temper her outlook despite a potential No. 1 ranking at stake if she advances, and Naomi Osaka’s consistent 2026 Slam runs have boosted her implied probability. Recent third-round results, including Osaka’s three-set victory and several American upsets, underscore the draw’s volatility, with quarterfinal matchups and rest factors likely to drive further shifts in trader consensus.
