National Bank Open: Jiri Lehecka vs Rafael Jodar

Platform comparison

Market context

Polymarket is pricing Jiri Lehecka vs Rafael Jodar at **48% YES** for Lehecka, so the contract is close to a coin flip rather than a clear favourite. On Polymarket, that price reflects the crowd’s current view of the chance Lehecka advances, with positions settled in **USDC** on **Polygon** through conditional tokens, and the market resolves to the player who actually advances rather than simply the pre-match favourite.[3]

That price fits a fairly balanced pre-match picture. Tennis Tonic’s preview has Jodar as the pick, while other books and market snapshots are only marginally split, including BetUS at roughly -110 Lehecka and -120 Jodar, and Tennis.com’s match page projecting Jódar slightly ahead at 52%.[1][2][5] In that kind of setup, a 48% Polymarket line usually reads less like conviction and more like uncertainty around form, ranking, and the fact that small pre-match edges can shift sharply in a best-of-three ATP setting.[3][6]

For traders, the main catalysts are the final ATP schedule confirmation, any late withdrawal or fitness update, and whether the match starts on time, because the market’s settlement rules change if the contest is cancelled, delayed beyond seven days, or ends without a winner.[4] The most important dependency is whether Lehecka and Jodar actually take court in Montréal on the expected date, since a walkover, retirement, or weather disruption can move the contract into the 50-50 fallback rather than a straight player outcome.[4][8]
