Hamburg European Open, Qualification: Valeriya Strakhova vs Chloe Paquet

Platform comparison

Market context

Valeriya Strakhova lost to Chloe Paquet 1–2 in the Hamburg European Open qualification match originally scheduled for 19 July 2026, meaning the contract on Polymarket has already resolved to “Chloe Paquet” and the 0% YES price for Strakhova is a post-event dead market. The trade is settled on-chain in USDC over Polygon, where conditional tokens now reflect the final outcome rather than any live probability.

Historically, when a tennis match finishes before a prediction market’s settlement window closes, Polymarket’s oracle locks the result immediately and the price collapses to 0% or 100% with no further volatility; similar cases in WTA events on the platform show volumes spiking only before the final ball, then freezing once the score is confirmed. The €122.88K volume recorded on this contract [1] occurred entirely before the match concluded, confirming that liquidity evaporated once the result was known.

Traders should watch for any official withdrawal notices or match-delay announcements from the Hamburg tournament, though none are expected given the match already finished [4]. The only remaining catalyst is the oracle’s formal resolution timestamp on-chain, which will lock the 50–50 tie clause as irrelevant since a winner was determined within the seven-day window. No further news sources are needed; the live result is already public and final [4].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Scam?, which mirrors the Polymarket order book directly.

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.
