Best Prediction Market Promos for the DC Open Quarter-Finals on 07-29-2026
The northern hemisphere hard-court swing gets underway this week as players head to Washington for the DC Open, and tennis fans can make use of their prediction market promos to put their knowledge to the test.
The WTA and ATP are in Washington for this round of the tour, so there are both men’s and women’s events this week, and the defending champions are in town. Australia’s Alex de Minaur and Canada’s Leylah Fernandez will both be seeking to retain their titles, but won’t have it their own way with competitive fields in both events.
Tips for the DC Open men’s and women’s events
Although he leads the field as both top seed and defending title holder, de Minaur needs to overcome a statistical wrinkle here as the last five men’s champions have all been different. Ben Shelton and Taylor Fritz will both feel they have a chance of unseating the Australian here, particularly as Shelton has been enjoying a breakout season. The best prediction markets are also buzzing with regard to the women’s draw, as World #3 Jessica Pegula has moved into the main draw due to player injuries, automatically becoming top seed and likely favorite to take the title. But with Fernandez in the field and keen to hold her title, along with Elena Svitolina and Naomi Osaka, this is a draw that’s alive with possibilities.
