US Open Odds
One announcement reshaped the men's board. Sinner withdraws from the US Open with a right knee injury that has kept the world No. 1 off court since he defended his Wimbledon title in July, which hands Alexander Zverev the top seed in New York.
Carlos Alcaraz still tops the market at +250 as he returns from a four-month wrist layoff, and the defending champion knows this surface better than anyone left in the draw. Novak Djokovic sits at +700 in what many observers treat as his last realistic run at a 25th major.
The women's draw stays far tighter. Aryna Sabalenka chases a third straight title at +330, with Coco Gauff at +450 and Iga Swiatek at +550, so grab the US Open betting promos above and lock in a number before the draw moves it.

- Alexander Zverev +300
- Novak Djokovic +700
- Ben Shelton +900
- Rafael Jodar +1200

US Open Prediction
Two picks stand out on the opening board, and both fit the first-bet structure of the US Open betting promos in our table.
Men's Pick: Carlos Alcaraz to Win the Title (+250): Alcaraz beat Sinner in four sets in last year's final and owns two titles in Flushing already. The wrist layoff creates real risk, yet the draw opens up with the top-ranked player out, and Zverev carries a poor record in New York for a man about to sit as the No. 1 seed.
Women's Pick: Coco Gauff to Win the Title (+450): Gauff's serve rebuild under biomechanics coach Gavin MacMillan finally holds up under pressure, and no player in the field draws more energy from an Arthur Ashe night session. Sabalenka arrives short on match wins since March, which cracks the door open for the 2023 champion.
US Open TV Schedule for First Round
ABC, ESPN and ESPN2 split the opening three days, so register for the US Open betting promos before the Sunday noon start and keep your account funded for the late sessions.
Sunday: US Open Tennis First Round, 12 p.m. ET to 3 p.m. ET on ABC, 3 p.m. ET to 4:30 p.m. ET on ESPN2, 4:30 p.m. ET to 11 p.m. ET on ESPN
Monday: US Open Tennis First Round, 11:30 a.m. ET to 6 p.m. ET on ESPN, 7 p.m. ET to 11:30 p.m. ET on ESPN
Tuesday: US Open Tennis First Round, 11:30 a.m. ET to 6 p.m. ET on ESPN, 7 p.m. ET to 11 p.m. ET on ESPN
Outside courts run on ESPN+ all fortnight, which matters if you chase live tennis betting promos and same-game parlays during the early upsets.

Where is Sports Betting Legal? Sportsbooks by State
Legal online sportsbooks operate in the majority of the country, though the app list changes the moment you cross a state line. The tables above show sportsbooks by state so you match an offer to your location before you register.
DraftKings and FanDuel post the widest maps at 24 and 25 states, respectively, and Fanatics Sportsbook promo code ACTION26 covers 24 states. BetMGM bonus code TOPACTION reaches 16 states with the $1,500 First Bet Offer, while betPARX, Hard Rock Bet, and Borgata stay regional.
Bettors in California, Texas, Georgia, and Florida find no legal online sportsbook at all, so prediction market apps fill that gap instead.
Prediction Markets
Kalshi and Polymarket accept traders in more than 40 states, including several with no sportsbook option. Both platforms price the tournament as yes-or-no contracts in cents rather than American odds, so a 30-cent contract implies roughly a 30% chance.
US Open Polymarket predictions keep Sabalenka at the front of the women's board in the high 20s to low 30s, closely tracking her +330 sportsbook price. Prices move throughout the day as traders react to news.
Women's US Open Polymarket odds spread wider than the sportsbook board, with Elena Rybakina and Iga Swiatek both attracting steady money behind the two-time defending champion. That extra spread creates value for anyone who fades the favorite.
Longer-dated career markets draw traffic too, and one question keeps resurfacing during Djokovic's run at a 25th major: will Djokovic retire before 2028? Traders watch his schedule commitments and Olympic ambitions for the answer.
1. Kalshi
The Kalshi promo code ACTION credits a $25 bonus after your first $25 in trades, and the exchange holds CFTC regulation as a federally designated contract market.
Kalshi lists tournament winner contracts for both draws, plus daily match markets, giving readers in non-betting states a route into US Open action.
| Kalshi Promo Code | Kalshi Referral Offer | Kalshi States Available |
|---|---|---|
| Kalshi Promo Code ACTION | Trade $25, Get $25 Bonus | AK, AL, AR, CA, CO, CT, DC, DE, FL, GA, HI, IA, ID, IN, KS, KY, LA, ME, MN, MO, MS, NC, ND, NE, NH, NJ, NM, NY, OK, OR, PA, RI, SC, SD, TN, TX, UT, VA, VT, WI, WV, WY |
2. Polymarket
The Polymarket promo code ACTION doubles a $10 deposit into a $20 trading bonus, which covers your first few contracts on the men's or women's winner market.
Heavy trading volume on both US Open markets keeps spreads tight through the fortnight, so entries and exits cost you very little on the way in or out.
