National Bank Open: Nicolas Mejia vs Martin Landaluce

Platform comparison

Market context

Nicolas Mejia against Martin Landaluce is a first-round National Bank Open match with no head-to-head history, which usually means the market price leans more on ranking, surface record, and recent form than on any direct matchup evidence. Landaluce is the higher-ranked player in the event listing at ATP No. 63 versus Mejia at No. 131, but the pricing is not overwhelmingly one-sided: nearby traditional books have quoted Landaluce around 1.40 decimal, implying roughly 71% before margin, while Mejia has been around 3.00, or about 33% raw implied chance.[10][17] That helps explain why Polymarket’s 18% YES looks comparatively low if “YES” means Mejia advances, though the exact exchange comparison depends on whether fees and spread are included.

The match context also matters because both players arrive with uneven hard-court profiles. Flashscore notes that Mejia is still seeking his first main-draw win at tour level on hard courts, while Landaluce has a 14-11 record this season against players ranked outside the top 100 and a 4-4 career first-round Masters mark.[1] Other stat aggregators show the split in another way: Landaluce’s hard-court and overall records are stronger than Mejia’s, but Mejia has shown better results on clay, making the Montreal surface a key filter rather than a blanket edge.[2][3] In platform terms, Betfair and Smarkets prices will usually be easiest to translate via decimal odds into implied probability, while Kalshi-style markets show the probability directly; fee treatment, KYC availability, and regional access can make the same matchup look slightly different across venues. The main catalysts before the settlement window closes are official schedule confirmation, any late withdrawal or retirement, and whether the match is completed within seven days of the original date, since cancellation or excessive delay would push the market to a 50-50 resolution.
