National Bank Open: Nikola Bartunkova vs Amanda Anisimova

Platform comparison

Market context

Amanda Anisimova’s match with Nikola Bartunkova at the National Bank Open is being priced as a clear favourite-vs-underdog contest, with the market at 75% for Anisimova. That sits broadly in line with external model and bookmaker signals: String Tension’s Elo projection gives Anisimova 73.2%, while Ladbrokes-listed prices in TennisExplorer’s match page imply roughly 70% for Anisimova from decimal odds of 1.44.[2][4] The gap is not large, but it does suggest the prediction market is slightly firmer than the average sportsbook read.

The historical frame also leans Anisimova’s way. There is no prior tour-level head-to-head, so traders are leaning on ranking, form and hard-court profile rather than matchup history.[2][3][13] Anisimova is the established top-10 player and has stronger recent hard-court results in comparator databases, while Bartunkova’s profile looks more volatile, despite a Toronto win over Clervie Ngounoue that may have helped her reach this stage.[7][15] In comparable first-time meetings where one player carries a significant class edge, market probabilities often cluster in the 65-80% range unless the favourite has clear fitness or scheduling concerns.

The main catalysts are practical rather than structural: confirmed start time, whether the match is actually played within the settlement window, and any late withdrawal or weather delay that could push the outcome into the market’s 50-50 fallback.[8][12] Flashscore and Sofascore both list the fixture but indicate live stats only once play begins, which means a scratch or postponement is the key binary risk for holders of either side.[1][8] If the draw order or court assignment changes, that matters less than whether Anisimova is active and ready, because the price already assumes she advances in normal conditions.[4][14]
