National Bank Open: Lanlana Tararudee vs Amanda Anisimova

Platform comparison

Market context

Lanlana Tararudee and Amanda Anisimova are due to meet in the National Bank Open round of 32, with Anisimova installed as the clear market and ranking favourite at WTA No. 9 versus Tararudee around No. 78-79. The crowd price near 50% suggests the market is still treating the matchup as live rather than one-way, but the underlying pre-match profile leans towards Anisimova on class, ranking and recent hard-court level.[4][6][5]

There is no previous head-to-head to anchor the pricing, so traders have to lean on comparable cases: the higher-ranked player usually carries most of the baseline expectation, while the underdog’s chance rises if the favourite has been inconsistent on return or is coming off a tight schedule. Form data from 2026 show Anisimova with a stronger win rate and more efficient hard-court numbers, including better hold and return indicators, which is the kind of profile that tends to justify a shorter outright price even without any direct matchup history.[2][5]

The key catalysts are straightforward: whether the match starts on time, whether the tournament keeps it on Centre Court, and whether any last-minute withdrawal or medical issue changes the pairing. A recent preview note also highlighted Anisimova’s strong National Bank Open record and a run of wins against lower-ranked opponents since June, both of which support the favourite case if the draw proceeds as scheduled.[6][9] Tararudee’s route is narrower but not closed; she has already put together a modest main-draw body of wins this season, so any early volatility, slow start or physical issue from Anisimova would matter quickly to live market pricing.[9][4]

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

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.
