Market context
Linda Noskova’s second-round meeting with Caty McNally at the National Bank Open has already produced a large gap between the market and the tennis data. The prediction market is pricing **0% YES**, but Tennis.com lists Noskova as an **78%** projected winner, implying a far more conventional favourite than the crowd price suggests.[12] That divergence is notable because Noskova is the higher-ranked player at **WTA No. 7** versus McNally at **No. 70**, and tournament records also point to Noskova’s stronger baseline profile.[10][12]
The historical frame is straightforward: McNally beat Noskova in their only previous meeting, a three-set ITF match in Trnava in 2022, so the head-to-head does not support a sweep in either direction.[4][5] That said, head-to-head alone usually carries less weight than current ranking and recent form, which is why the published tennis models still lean Noskova despite the 1-0 H2H edge for McNally.[4][12] In other words, the contract’s near-zero crowd price sits well outside the broader analyst and odds consensus, and looks more like an outlier than a true market view.[12][13]
For traders, the main catalysts are the match state itself and any official tournament scheduling changes. The National Bank Open match page shows the contest as completed on 5 August with Noskova winning **6-1, 6-1** in **1h38**, which would normally settle the contract for Noskova rather than 50-50 if the listed match is the relevant one.[10] If a separate scheduled meeting is still pending in your market feed, the key dependency is whether the bout is officially played within the settlement window or slips beyond seven days, since that would force a 50-50 resolution under the contract rules.
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets, which mirrors the Polymarket order book directly.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
