Hamburg European Open: Tessa Brockmann vs Elsa Jacquemot

Platform comparison

Market context

Tessa Brockmann’s meeting with Elsa Jacquemot in Hamburg has been priced far away from a coin-flip in most pre-match models, which makes the current **0% YES** crowd figure stand out as an obvious outlier rather than a market consensus. Tennis.com’s projected winner model gave Jacquemot a **64%** win probability, while Umpiry’s pre-match estimate was even more decisive at **77%** for Jacquemot and **23%** for Brockmann.[2][7] That gap matters for prediction-market readers because it suggests the contract’s crowd price is detached from the broader pre-match view, while sportsbook-style pricing also leaned Jacquemot’s way; one preview listed Jacquemot at **1.48** and Brockmann at **2.64**, equivalent to a clear favourite but not a near-certainty.[4]

For historical context, this is the kind of WTA match where live-status risk can matter as much as form: Brockmann entered as a wildcard, and the only direct comparison available in the surfaced results shows Jacquemot leading the head-to-head **2-0 in sets**, which supports the favourite case without making the result inevitable.[1][2] Because the market can still settle **50-50** if the match was not played, was tied, or was delayed beyond seven days without a winner, traders should watch for official tournament status updates and any postponement tied to Hamburg’s scheduling.[5] The match is also already reflected as having a live score entry with both players on the board, and 365Scores later recorded a final result of **Brockmann 0, Jacquemot 1**, which would ordinarily resolve this contract to Jacquemot if that completion is accepted by the market rules.[3][6]
