An outcome is considered unequivocally determined if it would have been guaranteed under every possible completion of the match played according to the match format published by the tournament organizer for that round. For example, for a line of 2.5, if play stops with the players at one set each, completing the match would have required at least one additional set, resulting in at least 3 sets played, so \"Over\" would resolve as the winning outcome. If neither outcome was already determined at the time play stopped, this market will resolve 50-50.\nIf the match is canceled, or has not been completed by November 23, 2026, 11:59 PM ET, this market will resolve 50-50, unless an outcome was already unequivocally determined as described above.\nThe primary resolution source for this market will be official Challenger statistics; however, a consensus of credible reporting may also be used.","image":"https://polymarket-upload.s3.us-east-2.amazonaws.com/atp-tour-b4390c4fb8.jpg","icon":"https://polymarket-upload.s3.us-east-2.amazonaws.com/atp-tour-b4390c4fb8.jpg","outcomes":["Over 2.5","Under 2.5"],"outcome_prices":[0.38,0.62],"probability":0.38,"spread":0.02,"active":true,"closed":false,"start_date":"2026-11-09T12:44:22Z","end_date":"2026-11-17T02:30:00Z","closed_time":null,"result":null,"volume":0.0,"volume_24hr":0.0,"prob_24h_change":-0.12,"volume_24h_change":0.0,"normalized_vol_24hr":null,"normalized_volume":null,"liquidity":1556.8576,"categories":["Sports"],"countries":[],"updated_at":"2026-11-09T15:14:53.840058Z","fetched_at":"2026-11-09T15:14:53.840058Z","added_at":"2026-11-09T12:50:20.317776Z","url":"https://polymarket.com/event/atp-mcdona-matsuda-2026-11-09/atp-mcdona-matsuda-2026-11-09-set-totals-2pt5","event_title":"Matsuyama: Niels McDonald vs Koki Matsuda","chart_24h":[0.5,0.38,0.375,0.38]},{"source":"polymarket","id":"6902749","event_id":"1348542","slug":"atp-mcdona-matsuda-2026-11-09-set-handicap-home-1pt5","question":"Set Handicap: Niels McDonald (-1.5) vs Koki Matsuda (+1.5)","group_item_title":"Matsuyama: Niels McDonald vs Koki Matsuda Set Handicap +/-1.5","description":"This market refers to the tennis match between Niels McDonald and Koki Matsuda in the Matsuyama, originally scheduled for November 9, 2026 at 9:30PM ET.\nThis market will resolve to \"Niels McDonald\" if Niels McDonald wins by 2 or more sets than Koki Matsuda, based on the final completed score.
