Description

The market centers on a professional tennis match between Joao Fonseca and Ben Shelton scheduled for the 2026 ATP Montreal Round Of 16. The outcome depends on which player wins the match after play has begun. If the match does not start due to injury, cancellation, or other issues, the market resolves to a fair price instead.

Kalshi

Both markets track the same tennis match between Joao Fonseca and Ben Shelton in the 2026 ATP Montreal Round Of 16, resolving based on the winner after at least one ball is played. If the match fails to start due to injury, walkover, forfeiture, or cancellation before any play occurs, the market resolves to a fair price. Postponements or delays keep the market open until the rescheduled match concludes, with resolution occurring within two weeks after the match ends. Kalshi disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
