Game Spread: Katerina Siniakova (-2.5) vs Katie Boulter (+2.5)

This market will resolve to "Katerina Siniakova" if Katerina Siniakova wins 2.5 or more total games than Katie Boulter in the upcoming tennis match, scheduled for October 24, 2026 at 12:30AM ET. Otherwise, this market will resolve to "Katie Boulter". 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 under the match format published by the tournament organizer for that round. For example, if the match ends at a point where Katerina Siniakova could no longer have finished 2.5 or more games ahead even by winning every remaining game, this market will resolve to "Katie Boulter". 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.
