This market refers to the tennis match between Aryna Sabalenka and Elena Rybakina in the US Open WTA, originally scheduled for September 12, 2026 at 4:00PM ET. This market will resolve to "Sabalenka" if Aryna Sabalenka wins by 2 or more sets than Elena Rybakina, based on the final completed score. Otherwise, it will resolve to "Rybakina." 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 deciding set has begun when the match ends, Aryna Sabalenka can no longer win by 2 or more sets, and this market will resolve to "Rybakina." If the match is canceled before play begins, or a result has not been determined by September 26, 2026, 11:59 PM ET (14 days after the scheduled start), this market will resolve 50-50. Resolution will be based on official Grand Slam results.
