Hamburg European Open, Qualification: Jessica Pieri vs Maria Lourdes Carle

Platform comparison

Market context

Jessica Pieri has already lost her Hamburg European Open qualification match against Maria Lourdes Carle, with the Argentine advancing 2–1 after the contest concluded on 20 July. The 0% YES probability for Pieri reflects this settled outcome rather than a pre-match forecast, as the match result is confirmed across multiple WTA trackers showing Carle’s victory in three sets[2][5].

In tennis prediction markets, a 0% implied probability typically signals a resolved event where the outcome is no longer uncertain, mirroring how markets close immediately once a match result is officialised. Historical cases show that when a match finishes before the settlement window, liquidity evaporates and prices lock to the actual result, leaving no room for reversal unless a formal replay or ruling overturns the scoreline—a rarity in WTA events.

Traders should monitor the official WTA tournament page for any post-match administrative updates, such as disqualifications or rule-based reversals, though none are expected given the standard clay-court adjudication process. No new announcements are pending, and the settlement window ending 27 July 2026 will simply confirm the already-determined result[1][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 Prediction Today, which mirrors the Polymarket order book directly.

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.
