Estoril Open: Kyrian Jacquet vs Alexander Blockx

Platform comparison

Market context

Polymarket is pricing the Kyrian Jacquet v Alexander Blockx contract at **51% YES** today, which is close to a coin flip and only slightly in favour of Jacquet advancing. On Polymarket, this position settles through **USDC** on **Polygon**, with the outcome tied to the market’s conditional token rules rather than a generic match result, so traders are really pricing who progresses under the contract terms.

That near-even read sits below several tennis preview models and bookmaker-style projections that lean towards Blockx. Tennis.com lists Blockx as the projected winner at **65%**, while Dimers and Stats Insider both put Blockx around **61%** to beat Jacquet, and The Stats Zone also tipped Blockx in straight sets.[1][5][7][4] Comparable pre-match forecasts like these usually matter most when the market is still liquid and before a result is formally confirmed, but the contract’s resolution language also means timing and official advancement matter more than raw scoreline narrative.

The key catalyst is the tournament’s actual administrative status: whether the match was completed, whether either player advanced, and whether any postponement pushes it beyond the seven-day settlement window, which would force a **50-50** resolution under the market rules. A live score listing from 365Scores says the match in Estoril on Wednesday, 22 July 2026 ended with a final score of **Kyrian Jacquet 1 - 0 Alexander Blockx**, while Tennis.com’s match page still showed Blockx as the projected winner, highlighting how quickly pre-match pricing can diverge from the eventual official outcome.[2][1]
