National Bank Open: Alexandra Eala vs Belinda Bencic

Platform comparison

Market context

Polymarket is pricing the contract at **49% YES** on USDC-settled, Polygon-based conditional tokens, so the market is effectively treating Alexandra Eala and Belinda Bencic as close to a coin flip rather than assigning a clear favourite. That lines up with independent match previews that have Bencic only narrowly ahead: Tennis.com listed Bencic at 52% projected win probability, while TAB pricing cited by Stats Insider had Bencic at $1.80 versus Eala at $2.00.[10][14]

The broader form data points in opposite directions. Bencic has the stronger season-long record in the cited stats, with TennisRatio showing 37-14 over the last 52 weeks versus Eala’s 38-26, and String Tension listing Bencic at 25-10 in 2026 compared with Eala’s 31-18.[1][3] But there is no tour-level head-to-head between them, which makes the first meeting harder to model and helps explain why the market sits just below parity rather than near a firm side.[3][11]

For traders, the key catalysts are the official match status, start time, and any late schedule movement out of the National Bank Open. Tennis.com had the match listed for the round of 16 on outdoor hard courts, and the market’s settlement terms mean a cancellation, tie, or delay of more than seven days forces a 50-50 outcome rather than a win for either side.[10] Bencic’s recent Toronto workload may also matter: WTA noted she reached the last 16 after a three-hour, 24-minute win over Taylor Townsend, which could affect freshness if there is a quick turnaround.[15]
