Estoril Open: Daniel Merida Aguilar vs Kyrian Jacquet

Platform comparison

Market context

Polymarket is pricing Daniel Merida Aguilar vs Kyrian Jacquet at **0% YES** on the contract today, even though the market description says the match was scheduled for 21 July and settles on who advances, with a 50-50 fallback if it is not played or is left unresolved beyond seven days. On-chain, this is a standard sports contract settled in **USDC** on **Polygon** through conditional tokens, so the key question for holders is not the abstract tennis matchup but whether an official result can still be matched to the event rules before the settlement window closes.

The comparable case that matters here is simple: if the match has already been completed, the contract should not stay near zero unless the market has not yet been updated or the event feed has not been resolved. Public tennis results show Jacquet won the Estoril Open meeting in three sets, 6-1, 6-1, 7-5, and match listings also show the contest as played at Estoril on 21 July 2026.[3][2] That is consistent with a market that would ultimately resolve to Jacquet rather than a 50-50 cancellation outcome, because the fallback only applies when there is no winner determined within the rule window.

For traders, the practical catalysts are all administrative: official tournament scoreboards, ATP draw updates, and any Polymarket resolution update that aligns the on-chain outcome with the completed match. If a market shows 0% despite a published final result, the relevant watchpoint is whether the contract has simply not been settled yet, not whether the tennis itself is still live.[1][3][7]
