National Bank Open: Nicolas Mejia vs Martin Landaluce

Platform comparison

Market context

Nicolas Mejia’s meeting with Martin Landaluce is a first-time ATP Masters main-draw pairing in Montréal, with no head-to-head history to anchor the price. Landaluce is the higher-ranked player at ATP No. 63 versus Mejia at No. 131, which helps explain why the market sits well below 50% for Mejia even though the gap is not enormous on paper.[1][7]

The comparable case for reading this kind of 18% implied chance is that rankings matter, but recent surface-specific evidence can quickly narrow the gap. Mejia is noted as still seeking his first main-draw win at tour-level on hard courts, while Landaluce has a 14-11 record this season against players outside the top 100 and a 4-4 career mark in Masters first-round matches.[1] That profile points to a live underdog rather than a routine mismatch, especially if the favourite’s recent results remain uneven.

For traders, the key catalysts are whether the match is confirmed to start on schedule, whether there is any rescheduling within the seven-day settlement window, and whether either player is withdrawn before first serve. Live scoreboards and match listings currently show the fixture as a Round 1 ATP Montréal event, but any late order-of-play change, walkover or cancellation would materially alter resolution risk because this market can settle 50-50 if the match is not played or is delayed too long without a winner.[7][14]

FAQ

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
