Livesport Prague Open: Antonia Ruzic vs Dominika Salkova

Platform comparison

Market context

Dominika Salkova has already defeated Antonia Ruzic in the first round of the Livesport Prague Open, with the match concluding on 20 July 2026 at 16:45 local time. Salkova won 7–6, 6–4, overcoming the 50th-ranked Croatian in a surprise result that ended Ruzic’s campaign as the highest-ranked foreign player in the tournament [1][2]. The market, which asks who advances from this encounter, now resolves definitively to Salkova, rendering the 0% YES probability for Ruzic accurate and final.

Historically, prediction markets on completed tennis matches with a clear winner resolve immediately once official results are confirmed, with no delay for appeal or review unless a formal protest is lodged within 24 hours. In WTA events, match outcomes are treated as final once the scoreline is published by the tournament’s official data provider, as seen in prior Prague Open rounds where upsets by qualifiers were settled without dispute [2][3]. The 50–50 tie clause applies only to unplayed or abandoned matches, which is not the case here.

Traders should monitor the WTA’s official match archive and Livesport Prague Open’s result page for any post-match administrative changes, though none are expected. The settlement window ending 2026-07-27 is redundant given the match’s completion, and no further catalysts—such as schedule updates or injury announcements—will alter the outcome [2]. The market’s resolution is now a matter of administrative confirmation rather than probabilistic forecasting.

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.
