Sabalenka Leads the Field

A Wide-Open Women’s Field

The Polymarket board gives several other contenders a realistic chance in New York, including Mirra Andreeva, Jessica Pegula, Linda Noskova, Alexandra Eala, and defending champion Amanda Anisimova.

Unlike the men’s market, where Jannik Sinner has separated himself from the field, the women’s board is considerably more balanced. Sabalenka leads, but the market is giving a much larger group of players a meaningful path to the title.

Polymarket Odds Will Continue to Move

The North American hard-court season is still underway, and injuries, results, withdrawals, and player form will all influence the Polymarket board before the US Open begins.
