US Open Predictions
Tail my US Open best bets below after you capitalize on my recommended tennis betting promos mentioned throughout this piece:
- Men's Pick: Alexander Zverev to Win the Title (+300): Zverev finally broke through this season, taking the Roland Garros title and reaching his first Wimbledon final weeks later. He also lands 72.2% of his first serves, the best mark of anyone inside the ATP's serve top 10, and the bracket hands him the softest route among the top four seeds.
- Women's Pick: Iga Swiatek to Win the Title (+550): Swiatek already owns a Flushing Meadows trophy from 2022, and these courts reward the pace and depth she generates off both wings. Traders on Polymarket keep pushing money her way at a shorter implied price than +550, which points to sharper support than the sportsbook board reflects.
