Two professional tennis players will compete in a high-stakes match during the 2026 ATP Montreal Round Of 16. The outcome depends entirely on which athlete claims victory after the first rally, with no alternative resolutions permitted for any pre-match disruptions.
Both markets resolve based solely on the named player winning the match after at least one ball is played. If the match fails to commence due to injury, withdrawal, or cancellation before any play occurs, the markets instead resolve to a fair price. Postponements or delays simply extend market activity until the rescheduled match concludes, with all determinations subject to these conditions.
