National Bank Open: Terence Atmane vs Jakub Mensik

Platform comparison

Market context

Terence Atmane’s match with Jakub Mensik in Montreal has opened with Mensik a clear favourite, which fits the market’s 19% YES price on an Atmane advance. Pre-match previews and bookmaker lines both lean strongly towards Mensik, with Tennis Tonic calling him to win in straight sets and listing no previous main-tour head-to-head between the pair.[1][2]

That lack of head-to-head makes recent level more important than history. Mensik is the higher-rated player in the market data and is being priced around 1.44–1.45 on the moneyline by the averaged odds feed, while Atmane sits roughly in the 2.75–2.90 range.[2] Tennis Temple’s live match page also shows a large split in projected win chances, with Mensik near 89% and Atmane around 10%, underscoring how far the market has moved towards the Czech player.[2][14]

For traders, the main catalysts are simple: whether the scheduled start is delayed, whether either player is carrying an unreported physical issue, and whether the match is completed within the market’s settlement rules. Polymarket’s own terms say a non-start, tie, or delay beyond seven days without a winner settles 50-50, and if the first set is not completed the market also resolves 50-50.[3] That makes official scheduling updates and any late player-news more important than usual, because the outcome can shift from a tennis read to a rules-based settlement.[3]

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

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.
