Description

This event tracks the outcome of a professional tennis match between two pairs of players competing in an ATP tournament. The result depends on which team emerges victorious after the match begins. If the match does not start due to cancellations, the outcome will be determined fairly based on circumstances.

Kalshi

The event resolves based on the winner of the Andreozzi / Guinard vs Geerts / Vliegen professional tennis match in the 2026 ATP Brussels Round Of 16, provided that play has commenced. If the match does not start—due to injury, walkover, forfeiture, or other cancellation before any ball is played—the market resolves to a fair price. If the match is postponed or delayed, the market remains open until the rescheduled match concludes, with a closure deadline of two weeks after the new match date. The event is independent of official league affiliations, and all trademarks remain property of their respective owners.
