Livesport Prague Open: Antonia Ruzic vs Dominika Salkova

Platform comparison

Market context

Antonia Ruzic and Dominika Salkova faced off in the round of 32 at the Livesport Prague Open on 20 July 2026, with the match already completed and Salkova advancing 2–0 (7–6, 7–6, 6–4) [2][3]. The prediction market in question, which resolves to the player who advances, currently shows a 0% implied probability for Ruzic winning, reflecting the settled outcome rather than pre-match uncertainty.

Historically, prediction markets that retain open settlement windows after a match concludes typically collapse to the actual result, rendering pre-event probabilities irrelevant once the outcome is known. Comparable cases in tennis markets show that when a match is fully played and a winner determined, implied probabilities shift to 100% for the victor and 0% for the loser, aligning with sportsbook closures and analyst consensus [5]. The 0% figure here is consistent with Salkova’s confirmed advancement, not a divergence in odds.

Traders should monitor official WTA Prague Open results archives and match completion confirmations, as any delay in result posting could temporarily sustain anomalous pricing. Maiden.bet’s pre-match analysis gave Ruzic a 59% chance, but that projection is now obsolete given the final score [5]. With the settlement window ending 27 July 2026, the market will resolve to Salkova unless a rare cancellation or tie clause is invoked, which is not applicable here [3]. No further announcements are expected, as the match outcome is definitive.

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.
