US Open Line Movement (Opening to Current)
- Jannik Sinner: +200 → +110
- Carlos Alcaraz: +200 → +170
- Ben Shelton: +4000 → +2800
The market has spoken loudly in favor of Sinner, whose price has nearly been cut in half from opening to current odds. Alcaraz also remains a strong contender, with modest movement showing steady confidence. Meanwhile, Shelton has seen his odds shorten significantly, signaling both sharp and public interest in the American as a dark horse. This line movement reflects both current form and the weight of betting action heading into the tournament.
US Open Most Bet Tickets
- Jannik Sinner (ITA): 21.1%
- Carlos Alcaraz (ESP): 19.9%
- Ben Shelton (USA): 11.3%
Sinner leads the way in overall betting volume, edging out Alcaraz by just over one percent. The presence of Shelton in the top three indicates the significant momentum the young American is gaining among bettors. His aggressive style and recent deep runs have made him a fan favorite, creating strong ticket volume despite longer odds.
US Open Most Bet Handle
- Jannik Sinner (ITA): 37.8%
- Carlos Alcaraz (ESP): 34.1%
- Ben Shelton (USA): 11.8%
The handle percentages show where the largest dollars are flowing, and it’s clear bettors are backing the two favorites with conviction. Sinner commands more than a third of the total money wagered, with Alcaraz close behind. Shelton rounds out the top three, and while his handle share is much lower, it matches his surge in tickets—an indicator of growing belief in his upset potential.
US Open Biggest Liability
- Ben Shelton (USA)
- Carlos Alcaraz (ESP)
- Jannik Sinner (ITA)
Shelton represents the largest liability for BetMGM, as his long odds coupled with heavy ticket interest would result in a costly payout for the book. Alcaraz follows closely, while Sinner—despite being the favorite—sits third due to shorter odds limiting his risk exposure. If Shelton makes a deep run, BetMGM could be sweating by the second week in New York.
