National Bank Open: Flavio Cobolli vs Yannick Hanfmann

Platform comparison

Market context

Polymarket is pricing this USDC-settled, Polygon-based contract at **55% YES** for Flavio Cobolli, which implies a modest edge over Yannick Hanfmann rather than a strong favourite. The market only resolves when the result is determined under the event rules; if the match is not played, is tied, or drifts more than seven days from the scheduled date without a winner, it falls back to 50-50.

The historical frame is thin because Cobolli and Hanfmann had not met before this National Bank Open match, so traders are leaning more on profile than direct head-to-head evidence. Cobolli’s career win rate is listed at 55.74%, versus 50.47% for Hanfmann, while both have workable hard-court records and recent-season results that do not separate them dramatically[1][10]. That profile is consistent with a market sitting just above even money rather than pricing in a lopsided matchup[1][4].

For traders, the main catalysts are straightforward: whether the match is officially played in Montreal, whether either player withdraws, and whether the draw timing forces a postponement or walkover that changes the settlement path. Tournament pages and live-score listings show the fixture on the hard court schedule, but pre-match prices can move quickly if the ATP draw is reshuffled or if either player’s status changes close to start time[5][9][11][12]. Because resolution depends on advancement, not just participation, any late cancellation, delay, or incomplete match outcome can matter more here than in a standard win-or-lose market[11].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
