National Bank Open: Oleksandra Oliynykova vs Karolina Pliskova

Platform comparison

Market context

Polymarket is pricing **0% YES** on Oleksandra Oliynykova against Karolina Pliskova, while the contract itself settles through USDC on Polygon via conditional tokens. The market is tied to whether Oliynykova advances in their National Bank Open meeting; if the match is not played, ends level, or is pushed beyond the seven-day window without a winner, the contract resolves 50-50 rather than a straight player win.

The historical frame does not support a strong case for an upset, but it is also not a market with a long direct rivalry to lean on: the pair had **no prior head-to-head** entering this event.[3][12][13] Pre-match projections from tennis outlets leaned towards Pliskova, with Tennis.com showing about **74%** for Pliskova and **26%** for Oliynykova.[7] That sits alongside Pliskova’s established WTA pedigree and a previous run to the Canadian Masters final in Montreal in 2021 and the semi-finals in Toronto in 2022, while Oliynykova is still relatively early in her tour-level record.[4]

For traders, the key catalysts are straightforward: official start-time changes, any withdrawal or retirement announcement, and whether the tie is actually completed inside the settlement window. The WTA’s match page listed the matchup as Round 1, and live stats later showed it had reached a completed result, which is the sort of event-level confirmation that determines whether a conditional-token market settles on a player or reverts to the fallback outcome.[5][8] Because this contract is mechanically linked to the match state, late schedule slippage or an on-court stoppage matters more than pre-match narrative.

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.
