Market context

Petra Marcinko defeated Simona Waltert 2–1 in the qualifying first round of the Lexus Eastbourne Open on 20 June 2026, securing her place in the main draw[1][8]. This result is now the settled real-world outcome, making the 100% YES probability on Marcinko advancing a factual certainty rather than a speculative forecast[2]. In prediction markets, such post-event pricing often reflects a lag in settlement automation; historically, markets with confirmed winners but unresolved status show similar delays before official closure, typically resolved within hours once the platform ingests the match result[1].

For a power-user building conditional order bots or copy-trading scripts, the key catalyst is not the match itself but the platform’s settlement trigger—specifically, the ingestion of the official WTA score report confirming Marcinko’s win[2]. Traders should monitor the WTA’s live scores page for the final match status update, as conditional orders tied to “match completed” will only execute once the system registers the result[4]. Recent coverage from Tennis Majors confirms the final score and player advancement, providing the authoritative data feed needed to validate automated strategies[1]. No further on-court action is required; the market’s resolution hinges entirely on this digital confirmation.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
