Valentini Grammatikopoulou and Alycia Parks compete in a professional tennis match during the 2026 WTA Athens tournament Round of 32 on July 13. The winner of this head-to-head matchup will advance in the competition.
Resolution requires that a ball be played in the match, establishing that competition has officially commenced. If the match does not occur before play begins due to injury, walkover, forfeiture, or other cancellation, the market resolves to a fair price. Should the match be postponed or delayed, the market remains open and closes only after the rescheduled match concludes, provided this occurs within two weeks of the original date.
