National Bank Open: Yannick Hanfmann vs Nuno Borges

Platform comparison

Market context

Polymarket is pricing **0% YES** on Yannick Hanfmann against Nuno Borges, so the contract is effectively saying the market sees Hanfmann as having no live chance of advancing unless there is a late correction or an unusual settlement outcome. The event is the National Bank Open men’s third-round match in Montréal, and the market pays out through USDC on Polygon via conditional tokens, with a 50-50 resolution only if the match is not played, ends level, or is delayed beyond seven days without a winner.

That zero bid looks extreme beside the broader market frame. The pair had no recorded head-to-head before this tournament, and pre-match pricing in other venues has generally treated Borges as the stronger side, with some bookmakers listing him as a clear favourite. Hanfmann’s path to a payout therefore depends on upsetting a higher-rated opponent in a hard-court Masters setting, where small differences in serve and return hold most of the edge.

For traders, the key catalyst is whether the match is actually completed and by whom, not the abstract tournament draw. The official match listings show the tie scheduled on Rogers Court on 6 August, but live scoreboards and broadcast listings can move quickly if there is a delay, retirement, or walkover, and that matters because Polymarket settles on the final tennis outcome or reverts to the contract’s fallback rules if the match is not decided in time. A live result source such as Sportschau or Tennis Temple is the cleanest signal to watch for any status change.

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.
