Pronóstico: National Bank Open: Taylor Townsend vs Belinda Bencic

Platform comparison

Market context

Polymarket is pricing **Belinda Bencic** as the clear favourite at about **63%** versus **37% YES** on Taylor Townsend, using USDC on Polygon through conditional tokens. That makes the market slightly less bullish on Bencic than many sportsbook and model prices, where Bencic was widely listed around the low 1.3s in decimal terms and Taylor Townsend around the mid-3s, implying a notably stronger edge for Bencic than the contract suggests.[1][2][3][5]

The read-through from comparable pricing is straightforward: when this pairing has been modelled, Bencic has usually been treated as the likelier winner, and Polymarket’s current level still reflects that baseline even after taking in event-specific uncertainty. Tennis Tonic and other prediction pages also leaned Bencic, while Polymarket’s own Taylor Townsend page showed the match contract around **27%/74%** earlier in the day, indicating the market has already moved in Bencic’s favour but remains well short of a near-lock.[1][5][6][7]

For traders, the main catalysts are not just the players’ form but the match administration itself: official start-time changes, court assignment, weather interruptions, and any withdrawal or retirement news from the National Bank Open draw. Polymarket’s rules matter here, because if the match starts and is not completed, or if it is cancelled before play or delayed beyond seven days without a result, the contract resolves **50-50** rather than to either player.[3][4]
