Market context
Julia Avdeeva lost her Hamburg European Open qualification match against Jule Niemeier on 19 July 2026, finishing 1–2 in sets, which explains the contract’s current 0% YES price for Avdeeva advancing. On Polymarket, this USDC-denominated contract on Polygon now reflects a settled outcome rather than a live probability, as the match has already concluded and the conditional tokens for Avdeeva advancing are effectively worthless.
Historically, when a tennis match finishes before a prediction market’s settlement window closes, prices collapse to zero for the losing player’s outcome within minutes, mirroring how conditional tokens on Polygon reprice instantly once on-chain oracles confirm the result. Similar cases from WTA qualifiers in 2024 and 2025 show that 0% pricing is standard once the match result is official, with no meaningful rebound unless the market is mis-settled due to oracle delay.
Traders should monitor the official settlement status on Polymarket’s resolution page and confirm that the oracle has recorded Niemeier’s 2–1 victory, as any delay could temporarily sustain the 0% price before correction. No further announcements or schedule changes are relevant, given the match’s completion; the only dependency is the finalisation of the on-chain resolution, which typically occurs within hours of the official result being published by the WTA.
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.
