Wimbledon 2026 has arrived at an unusually chaotic moment for tennis, and the betting markets are reflecting every bit of that uncertainty.
Jannik Sinner enters the grass-court major as the overwhelming men's favorite, a status that hasn't changed despite a jarring second-round exit at the French Open just weeks ago. With Carlos Alcaraz still sidelined through injury, Sinner's path to a second consecutive Wimbledon title looks clearer than ever, Tennis Abstract odds place his probability of lifting the trophy at a remarkable 58.6%. His first serious test may not come until a potential quarterfinal meeting with Daniil Medvedev.
On the women's side, Aryna Sabalenka opens as the favorite at +350 on DraftKings Sportsbook, with 2022 champion Elena Rybakina close behind at +550 and 2025 winner Iga Swiatek checking in at +750. The women's draw feels particularly wide open, Swiatek has been bageled in deciding sets multiple times in recent weeks, and no rapidly ascending player has yet claimed a Slam title.
Then there's the storyline swallowing everything else whole: Serena Williams. Nearly four years removed from Grand Slam singles competition, the 44-year-old legend has returned on a wildcard entry, and the betting public is already buzzing. Her odds have swung dramatically, from 28-1 on Tuesday, out to 50-1 by Thursday, before settling back around 35-1. Caesars Sportsbook's head of tennis Lewis Harland confirmed his team is "absolutely" anticipating heavy public support for Williams, especially from American bettors backing the all-time great's comeback.
She opens against 20-year-old Maya Joint in the first round, a matchup analysts have described as a favorable draw for the returning champion.
TennisDraw users flagged Sinner and Sabalenka as dominant bracket picks heading into Wimbledon's opening week.
