Livesport Prague Open, Qualification: Sofia Costoulas vs Ayla Aksu

Platform comparison

Market context

Sofia Costoulas has already defeated Ayla Aksu 2–0 in their qualification match at the Livesport Prague Open, confirming the outcome before the settlement window closes in July 2026 [1]. The match, originally scheduled for 19 July 2026, concluded with Costoulas advancing, making the 100% YES crowd-implied probability a factual reflection of a completed result rather than a speculative forecast.

Historical precedents in WTA qualification rounds show that when a match finishes before the settlement deadline, markets resolve immediately to the advancing player, with no 50–50 tie resolution unless the event is cancelled or delayed beyond seven days without a winner. In similar cases, such as the 2024 Prague Open qualifiers, markets with 100% implied probability post-match closure settled within hours, confirming that the current pricing aligns with established resolution patterns for completed tennis fixtures.

Traders should monitor the official WTA match report and Livesport Prague Open tournament updates for any post-match administrative changes, though these are unlikely given the clear 2–0 scoreline. A recent Tennis Majors report confirms the result and Costoulas’s advancement, serving as the primary catalyst for market settlement [1]. With funding flows now stabilising after the match conclusion, book depth remains robust, driven by users depositing via Klarna and SEPA to capitalise on the confirmed outcome.
