National Bank Open: Benjamin Bonzi vs Yannick Hanfmann

Platform comparison

Market context

Benjamin Bonzi is due to play Yannick Hanfmann in Montreal at the National Bank Open, and in this market a **YES** share would pay out if Bonzi advances, while a **NO** share would pay out if Hanfmann advances. The current crowd price of 0% YES implies the market is assigning almost no chance to a Bonzi win, but the contract still resolves on the actual match result unless the event is not played, is tied, or slips beyond the seven-day delay rule, in which case it settles 50-50.

The historical frame is thin because the pair have no recorded head-to-head, so traders are leaning instead on recent form and surface splits. Hanfmann has generally posted the stronger win rate across the last 12 months and appears the more established tour-level player, while Bonzi’s profile has been more mixed and he has been described in recent match previews as carrying the benefit of time already spent on North American hard courts.[2][4][12] That combination helps explain why the market can start from a heavily one-sided baseline even before the first point is played.[2][7]

The main catalysts are administrative rather than thematic: confirm the match start time, whether it is moved on the schedule, and whether either player withdraws before play begins. Live schedule pages currently place the match in Montreal on 2–3 August with differing local-time listings, which is exactly the kind of pre-match uncertainty that can matter for a market with a 7-day delay clause.[1][10][15][16] If the match is postponed, abandoned after starting, or replayed under tournament rules, the settlement outcome depends on whether a winner is eventually recorded within the window, so traders should watch official draw updates and live scoring feeds closely.[1][3]

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 Prediction Market UK, 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.
