National Bank Open: Rafael Jodar vs Corentin Moutet

Platform comparison

Market context

Rafael Jodar and Corentin Moutet are due to meet at the National Bank Open, and the market’s 73% crowd-implied probability points to Jodar being viewed as the more likely advancer. That is broadly consistent with the wider pricing landscape: on fixed-odds venues, the same idea is usually expressed as decimal odds rather than a yes/no probability, while peer-to-peer books such as Betfair and Smarkets typically show a back/lay spread that can move faster around team news, with fees and KYC access shaping who can actually trade. The matchup is also a first-time meeting, so there is no direct head-to-head history to anchor a projection, and the main frame is form and ranking rather than matchup precedent.[1][3][5][12]

The comparative numbers are mixed but still make Jodar’s strength easier to explain than Moutet’s volatility. Jodar is listed around ATP No 15 with a 2026 win rate in the low-70s across the season, while Moutet is around ATP No 59 and has a much weaker season record, even if his career experience is far greater.[1][2][12] That gap matters more on platforms that price in percentage terms, because a 73% market can look modest on Polymarket but may correspond to shorter decimal odds elsewhere; on exchange-style books, by contrast, traders will watch whether liquidity narrows the spread as the start time approaches.[1][2][15]

The main catalysts are straightforward: final order-of-play confirmation, any late withdrawal or retirement risk, and whether the match actually begins within the market’s settlement window. Tennis listings currently place the match on 5 August 2026 in Montréal, and live event pages already carry the pairing, which suggests the key risk is not ambiguity over the opponent but whether scheduling or weather pushes the contest far enough back to trigger a no-result-style settlement.[6][7][11][17] Because this market resolves to 50-50 if the match is not played or is delayed beyond seven days without a winner, traders should focus less on pre-match chatter and more on whether the tournament proceeds exactly as scheduled.[market description]
