Livesport Prague Open: Antonia Ruzic vs Dominika Salkova

Platform comparison

Market context

Antonia Ruzic, the world number 50, faced Dominika Salkova in the Livesport Prague Open on 20 July 2026, with the match now concluded as Salkova secured a surprising 7–6, 6–4 victory over the higher-ranked Czech qualifier [1]. The crowd-implied probability of 0% YES for Ruzic advancing reflects this definitive outcome, where Salkova, the lowest-ranked foreign player at the tournament, eliminated the most seeded international entrant in a tight two-set affair [1]. Historically, such 0% probabilities in prediction markets post-match signal a resolved event rather than a speculative edge; comparable cases from WTA Prague show that when a qualifier beats a top-50 opponent in straight sets, the market closes immediately with no further trading value, as the result is no longer uncertain [1].

Traders should note that the settlement window ends 2026-07-27, but the match result is already confirmed, meaning no further catalysts like schedule changes or injury announcements will alter the outcome [1]. The initial odds favoured Ruzic at 1.64 against Salkova’s 2.25, with most analysts including Tennis Tonic and Maiden predicting a Ruzic win in three sets, yet Salkova’s straight-set victory overturned these expectations [3][5]. This contrarian angle—where a qualifier defeats a higher-ranked player in a single session—typically creates no lingering value spots once the result is known, as the market has already priced in the certainty of Salkova’s advancement [1]. For who-will-win.co.uk users, the 0% probability is not a signal to trade but a confirmation of the settled result.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
