In the upcoming US Open ATP singles match between Lloyd Harris and Stefanos Tsitsipas, scheduled for September 2, 2026 at 11:00AM ET: This market will resolve based on the final set score of the Lloyd Harris vs. Stefanos Tsitsipas match. This match is played in a best-of-5-sets format. The possible outcomes are 3-0, 3-1, “Not Completed”, and 3-2 in either direction. If the match is canceled (not played at all), or is delayed beyond 14 days from the scheduled date at 11:59 PM ET without completion, this market will resolve to 'Not Completed'. If the match begins but is not completed, and one player advances due to the opponent's retirement, default, or disqualification, this market will resolve to 'Not Completed' regardless of the set score at the time. If the match ends in a walkover (player withdraws before the start and the other advances automatically), this market will resolve to 'Not Completed'. The primary resolution source will be official information from the ATP Tour. A consensus of credible reporting may also be used.

On Polymarket, this market reflects trader sentiment rather than traditional sportsbook lines. Prediction market odds often diverge due to different participant dynamics and information sources. Traders may price in nuances not captured by sportsbooks, such as recent form or injury updates. The market’s probability output can therefore appear higher or lower than sportsbook odds, depending on how Polymarket users interpret available data. This difference provides an alternative view of expected outcomes for the Lloyd Harris vs. Tsitsipas exact score.
This market resolves around Sep 9, 2026, with the outcome confirmed once the match result is verifiable from credible public reporting. The exact final score reported by authoritative sports news sources will determine which market position is settled as the winner, closing all open positions at that time.
Several signals could shift probabilities in this market before Sep 9, 2026. Key factors include player injuries, recent match performances, and changes in tournament conditions like surface or weather. Media commentary and expert analysis may also sway trader sentiment. As the event approaches, betting patterns on traditional sportsbooks might influence Polymarket prices, especially if large bets are placed. Any last-minute updates regarding player fitness or strategy could produce notable adjustments in the market’s priced outcomes.
