Canadian Open, Qualification: Marco Trungelliti vs Nicolas Mejia

Platform comparison

Market context

Marco Trungelliti and Nicolas Mejia are in a Canadian Open qualifying match on outdoor hard courts in Montréal, with the scheduled start listed at 14:30 UTC on Court 9. Live listings show the match under way and into the third set, so the immediate market question is no longer about pre-match probability but about whether the governing rules allow a clean winner to be recorded before any interruption becomes relevant.[1][2]

For probability reading, the cleanest comparable frame is a qualifying tennis market with an established favourite-price gap rather than a coin flip: Trungelliti is the higher-ranked player in the live listings at ATP 91 versus Mejia at ATP 131, while other market feeds had already priced Trungelliti as the clear favourite before play. That kind of profile usually means a 0% crowd-implied YES is less a view on tennis strength than a reflection of market mechanics, stale liquidity, or a binary that has already been priced through by live conditions.[2][19][16]

A power-user approach is to monitor two separate triggers programmatically: first, the live scoring feed for match completion, and second, the event status for any retirement, suspension, or schedule slip beyond the seven-day settlement window. Polymarket’s contract language says the market resolves YES only if all required sets and games are completed through normal play, and otherwise falls to NO; by contrast, a non-played cancellation, tie, or delay beyond seven days from the scheduled date resolves 50-50. That means an automation stack should watch the scoreboard, the tournament schedule, and any official match-status changes, because a started match can still fail to settle as a standard winner if it is not completed.[4][2]
