In the upcoming US Open ATP singles match between Karen Khachanov and Alexander Blockx, scheduled for September 9, 2026 at 11:30AM ET: This market will resolve based on the final set score of the Karen Khachanov vs. Alexander Blockx 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.

Prediction market odds often reflect a different perspective than traditional sportsbooks. Sportsbooks set lines to balance action and incorporate a profit margin, while this market represents the collective wisdom of traders who are incentivized to make accurate predictions. Discrepancies can arise due to differing information, biases, or simply varying interpretations of the players' form and potential. It’s common to see prediction markets move independently of sportsbook odds, especially as new information becomes available or as the event draws nearer. Analyzing these differences can be a valuable exercise for informed forecasting.
On Polymarket, this market is priced through a continuous exchange mechanism where traders buy and sell shares representing different possible exact scores in the Khachanov vs. Blockx match. The price of each share reflects the market’s assessment of the probability of that outcome occurring. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As more traders participate and new information emerges, the prices adjust to reflect the evolving consensus. This dynamic pricing ensures that the market odds are constantly updated and responsive to changes in perceived likelihood.
This market resolves around Sep 16, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final, official score of the Khachanov vs. Blockx match, as reported by a recognized tennis authority, will determine the winning share(s) in this market.

Traders should monitor official sources for the definitive outcome.
Several factors could influence the trading activity and price movement in this market. News regarding player injuries, changes in playing conditions, or even pre-match interviews revealing strategic insights could all impact trader sentiment.
