These markets assess whether Frances Tiafoe will win the match by a sufficient margin of games over Rei Sakamoto. Different thresholds define what constitutes a decisive victory for Tiafoe in their US Open encounter.
All markets for the Rei Sakamoto vs Frances Tiafoe match at the 2026 US Open Men Singles Round Of 64 resolve based on the game differential in favor of Frances Tiafoe across the full match. If the match does not occur due to injury, walkover, forfeiture, or cancellation before play begins, markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes within two weeks. In case of retirement, markets that can be settled based on completed play resolve accordingly, while unresolved markets determine Fair Market Price at the Exchange's discretion. The Exchange disclaims any affiliation with the governing league, and all trademarks remain property of their respective owners.
