A postponement alone will not trigger a 50-50 resolution.\nIf the match is permanently abandoned before completion, or if the match has not been completed by September 13, 2026, 11:59 PM ET, this market will resolve 50-50, unless the outcome has already been unconditionally determined based on completed play. An outcome is considered determined if it would have been guaranteed had the match been played to completion using the minimum number of additional games required. For example, for a line of 21.5, if play stops at 6-3, 5-6, completing the match would have required at least 2 additional games, resulting in at least 22 games played, so \"Over\" would resolve as the winning outcome.\nThe primary resolution source for this market will be official Grand Slam statistics; however, a consensus of credible reporting may also be used.","image":"https://polymarket-upload.s3.us-east-2.amazonaws.com/wta-logo-41f331bdf1.png","icon":"https://polymarket-upload.s3.us-east-2.amazonaws.com/wta-logo-41f331bdf1.png","outcomes":["Over","Under"],"outcome_prices":[0.23,0.77],"probability":0.23,"spread":0.2,"active":true,"closed":false,"start_date":"2026-08-28T04:45:35Z","end_date":"2026-09-06T15:00:00Z","closed_time":null,"volume":0.0,"volume_24hr":0.0,"prob_24h_change":-0.27,"volume_24h_change":0.0,"normalized_vol_24hr":null,"normalized_volume":null,"liquidity":560.857,"categories":["Sports"],"countries":[],"updated_at":"2026-08-29T04:13:21.032929Z","fetched_at":"2026-08-29T04:13:21.032929Z","added_at":"2026-08-28T04:52:17.154621Z","url":"https://polymarket.com/event/wta-svitoli-sierra-2026-08-30/wta-svitoli-sierra-2026-08-30-match-total-22pt5","event_title":"US Open WTA: Elina Svitolina vs Solana Sierra","chart_24h":[0.5,0.5,0.35,0.345,0.5,0.355,0.47,0.315,0.285,0.24,0.205,0.215,0.21,0.225,0.22,0.23]}],"_meta":{"attribution":"pdata.world — aggregated prediction-market data across 8 platforms","canonical_url":"https://pdata.world/events/polymarket/924110","as_of":"2026-08-29T04:17:20.334620Z","docs":"https://api.pdata.world/docs","cite_as":"According to pdata.world (tracking Polymarket): \"US Open WTA: Elina Svitolina vs Solana Sierra\" — top market at 92% probability across 16 outcomes","source_url":null}}
