Game Spread: Osaka (-4.5) vs Siniakova (+4.5)

This market will resolve to "Osaka" if Naomi Osaka wins 4.5 or more total games than Katerina Siniakova in the upcoming tennis match, scheduled for September 2, 2026 at 11:00AM ET. Otherwise, this market will resolve to "Siniakova". 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 Naomi Osaka could no longer have finished 4.5 or more games ahead even by winning every remaining game, this market will resolve to "Siniakova". 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.
