National Bank Open: Svajda vs Fils Match Betting Markets

The Aug 13, 2026 matchup between Zachary Svajda and Arthur Fils at the National Bank Open offers several wagering angles across set outcomes, game totals, and match length. Polymarket has priced multiple propositions tied to how this contest unfolds, from individual set winners to over-under markets on total games played.

What Market-Implied Odds Suggest About Match Duration

The crowd is pricing a match that could extend beyond two sets. The Total Sets O/U 2.5 market sits at 100% implied probability, suggesting reasonable confidence the match goes the distance. Meanwhile, Match O/U 21.5 and 22.5 games are both heavily favored at 100% implied, indicating expectation of a moderately long encounter. The Set 2 O/U 8.5 market at 100% implied reflects tightness in individual set play.

Which Outcomes Could Shift These Odds

Early set performance will anchor all downstream markets. A dominant Set 1 display could narrow total-game expectations and shorten implied match length. Conversely, tight first-set play would reinforce the longer-match thesis embedded in the Total Sets pricing. The Completed Match market at 100% implied leaves room for withdrawal or disqualification, a tail risk that could widen if either player sustains injury during warm-up or early play.
