Pronóstico: National Bank Open: Linda Noskova vs Caty McNally

Platform comparison

Market context

Linda Noskova vs Caty McNally is trading at **0% YES** on Polymarket right now, so the contract is effectively pricing an upset-free path to McNally or some unresolved outcome rather than a Noskova advance. On Polymarket, buyers fund USDC into a Polygon-based conditional token contract, and the market pays out on the resolved winner unless the match is not played, ends in a tie, or is delayed beyond seven days, in which case it settles 50-50 under the market rules.

The historical read is straightforward: Noskova comes in with the stronger tour profile, sitting far higher in the WTA rankings than McNally, but McNally already owns the only completed head-to-head between them, winning their 2022 meeting on hard court in Trnava in three sets.[1][2][12] That makes this less of a clean favourite-short than the rankings suggest, especially on Toronto’s hard courts where a single match can turn on serve patterns and tie-break variance. Comparable markets often stay compressed when the lower-ranked player has a live surface fit and a prior win, even if the favourite’s season-long numbers are stronger.[3][5]

For traders, the practical catalysts are simple: the match must actually begin and finish, and any late scheduling change at the National Bank Open can matter more than pre-match ranking talk. The tournament site already lists the second-round meeting as completed, with Noskova having advanced over McNally on 5 August in 1 hour 38 minutes, so any open contract tied to the same pairing will typically hinge on whether settlement data has propagated correctly and whether the market refers to that finished match or a separate rescheduled instance.[8] If fresh draw updates, retirement notices, or official result corrections appear, those are the main drivers that can move a contract from a live-price view towards a hard resolution.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
