Jannik Sinner is the -125 favourite for the US Open 2026 at bet365 after retaining Wimbledon, while defending champion Carlos Alcaraz — sidelined by a wrist injury since April — drifts to +175 with six weeks until Flushing Meadows.
Jannik Sinner leads the US Open 2026 odds at 1.80 (-125 American) at bet365 after beating Alexander Zverev 6-7, 7-6, 6-3, 6-4 in the July 12 Wimbledon final — his fifth Grand Slam title. Polymarket agrees, pricing Sinner at 56.5% for the major that runs August 23 to September 13, 2026 in New York, with injured holder Carlos Alcaraz back at 12%.

• Sinner beat Zverev 6-7, 7-6, 6-3, 6-4 in the Wimbledon final — his 10th straight win over the German — ESPN

Why Sinner is odds-on six weeks out
American odds of -125 mean a $125 stake wins $100; the decimal 1.80 shows total return per unit, implying roughly 55% with the margin stripped — almost exactly where Polymarket’s 56.5¢ sits. The case is straightforward: Sinner won all five Masters titles he contested before Roland Garros, has now defended Wimbledon, and his baseline pressure and return game fit Flushing Meadows’ hard courts better than any other surface.
The Alcaraz question hangs over the board
Alcaraz is why this market is more interesting than the headline price suggests. The defending champion has not hit a competitive ball since hurting his wrist in April, and at +175 he is priced on reputation rather than match fitness; until he posts results at a hard-court warm-up — Cincinnati is the checkpoint — the second favourite is an unpriced injury risk. “It’s just staying in the moment, to be honest,” said Jannik Sinner, world number one, in his Wimbledon final press conference.

The chasing pack: Zverev’s form, Djokovic’s ceiling
Zverev reached the Wimbledon final and pushed Sinner to two tie-breaks, but the head-to-head is the problem: 10 straight defeats to the Italian, per ESPN, which caps his title equity in any draw Sinner survives. Djokovic, 5.8% on Polymarket, was beaten in straight sets in the semi-final yet remains the field’s most proven hard-court closer — the question at that price is whether he can win seven best-of-five matches in New York heat.
The Betting Angle
Favourite: Jannik Sinner at -125 (American) / 1.80 (decimal) at bet365 as of July 16, 2026; Polymarket has him 56.5%. He arrives on back-to-back Slams and a dominant 2026 hard-court record.
Predicted result: Sinner wins the US Open 2026, beating Zverev in a repeat of the Wimbledon final — grounded in the 10-0 head-to-head and Alcaraz’s fitness cloud.
Prop bets worth a look:
- Zverev outright at 7.8¢ on Polymarket — consecutive Slam finals is real form, and a draw that keeps Sinner on the other side makes the final a live path.
- Djokovic outright at 5.8¢ on Polymarket — a small-stakes angle on the field’s best remaining hard-court résumé at a single-digit price.
- Alcaraz at +175 — only after Cincinnati — if he enters and wins matches at the warm-up, the price will shorten fast; until then the market is pricing a name, not a player.
What to fade: Alcaraz at +175 today. No competitive match since April, a wrist injury on his hitting side, and a missed Wimbledon — second-favouritism on reputation alone is the softest price on the board.
