Game Spread: Marta Kostyuk (-4.5) vs Liudmila Samsonova (+4.5)

This market will resolve to "Marta Kostyuk" if Marta Kostyuk wins 4.5 or more total games than Liudmila Samsonova in the upcoming tennis match, scheduled for September 17, 2026 at 12:00PM ET. Otherwise, this market will resolve to "Liudmila Samsonova". Games won will be counted across all sets played in the match. A set decided by a tiebreak will count as one game for the winner of that tiebreak, and a match tiebreak played in place of a final set will also count as one game for its winner. If the match is canceled (not played at all), or is delayed beyond 14 days from the scheduled date without completion at 11:59 PM ET, this market will resolve 50-50. If the match begins but is not completed due to retirement, default, or disqualification, this market will resolve 50-50, unless the outcome of this market has already been unconditionally determined by the completed portion of play. For example, if the match ends at a point where Marta Kostyuk could no longer have finished 4.5 or more games ahead even by winning every remaining game, this market will resolve to "Liudmila Samsonova". If the match ends in a walkover (player withdraws before the start and the other advances automatically), this market will resolve to 50-50. The primary resolution source will be official information from the WTA Tour. A consensus of credible reporting may also be used.
