This market assesses the performance difference between Frances Tiafoe and Alex Michelsen across their 2026 US Open Men Singles Quarterfinal match. It determines whether Tiafoe wins by a sufficient margin or if Michelsen maintains competitive parity.
These markets resolve based on the game differential between Frances Tiafoe and Alex Michelsen in their 2026 US Open Men Singles Quarterfinal. The first market resolves if Tiafoe's game differential exceeds 5.5 games; the second if it exceeds 2.5 games; and the third if Michelsen's differential exceeds 1.5 games. As with other markets, if the match does not occur before play begins due to injury, walkover, forfeiture, or cancellation, it resolves to a fair price. Postponements or delays keep the market open until the rescheduled match finishes. Retirement allows resolution based on completed play; otherwise, unresolved markets resolve to Fair Market Price at the Exchange's discretion.
