Warsaw: Justina Mikulskyte vs Gabriela Knutson

Platform comparison

Market context

Polymarket is pricing this Warsaw quarter-final at **0% YES** today, which means the contract is effectively treated as dead on the current order book unless fresh information changes the setup. On-chain, that price reflects a USDC-denominated position on Polygon via conditional tokens, so any late move in scheduling or match status feeds directly into settlement rather than the underlying tennis market in the abstract.

For context, Gabriela Knutson already owns the clearest recent edge in the head-to-head: the pair were level at 0-0 in one tournament listing, but other match databases show Knutson ahead overall, including a straight-sets win in 2025 and a three-set win at Midland in 2024. Mikulskyte has taken matches on tour as well, but the historical pattern points to Knutson being the more proven side when these two meet, which is the sort of record traders usually lean on when a market is thin and near-flat.

The practical catalysts are simple: the match has to be played, and played to completion, before the settlement window closes. Live tennis listings currently place the quarter-final on Centre Court in Warsaw on 6 August, with the scheduled start around 09:00 local time, but any delay, walkover, retirement, or cancellation can flip the contract towards a 50-50 resolution under the market rules. Traders watching this contract usually focus on the official order of play, final score updates, and whether either player withdraws or advances without a completed match, because those are the events that matter for conditional-token settlement.

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.
