National Bank Open: Gabriel Diallo vs Kyrian Jacquet

Platform comparison

Market context

Gabriel Diallo’s first-round match with Kyrian Jacquet at the National Bank Open is priced as a near-certain Diallo advance, but the broader market still shows a meaningful split on the actual match line. Published odds and model estimates cluster around a modest Diallo edge rather than a blowout: Tennis Tonic made Diallo the pick at 1.55, while other pre-match screens put him only slightly ahead or even close to a coin flip. The main historical frame is that there is no main-tour head-to-head between the pair, so traders are leaning on ranking, recent tour level, and home conditions rather than any direct matchup evidence.[1][4][6][13][18]

The key line-moving factor is whether the scheduled draw state changes, not just who is favoured on court. The Athletic listed the fixture for Monday 3 August at 1 p.m., while other live schedules showed the match in Montreal on Sunday evening, so any rescheduling, walkover, or delay matters for settlement risk as much as form.[3][4][12] Jacquet was listed around ATP No. 120 and Diallo around No. 99 on live match pages, which supports the market’s baseline preference for Diallo, but the spread is not wide enough to ignore late withdrawals, court-order changes, or an incomplete match that still produces an advancing player.[6][7]

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
