Mubadala Citi DC Open, Qualification: Polina Kudermetova vs Varvara Lepchenko

Platform comparison

Market context

Polina Kudermetova and Varvara Lepchenko were scheduled to meet in Washington qualifying for the Mubadala Citi DC Open, and the market’s 100% implied yes is effectively pricing in that the match is the one already under way rather than a fresh toss-up. Tennis.com listed Kudermetova as the projected winner at 61%, while Tennis Tonic’s preview also leaned to Kudermetova, so the live market is much more decisive than the pre-match consensus suggested.[2][4]

For framing, the cleanest comparable is their recent head-to-head history: Tennis Tonic said this was the third meeting in their careers, and 365Scores recorded Kudermetova beating Lepchenko in straight sets in Mérida in 2024.[4][6] That makes the current 100% price easier to read as a state-of-play signal than a pure skill forecast, because in tennis qualification markets the biggest shifts often come from whether a match has started, whether a retirement occurs, or whether a walkover triggers the market’s special settlement rules.[1]

The main catalyst to watch is match status, not a polling move: Polymarket’s rules say a retirement or default after the match begins resolves to the player who advances, but a pre-start walkover resolves 50-50.[1] RIA’s event listing said the scheduled start was 26 July 2026 at 17:00 local time and still marked the match as not started at publication time, so any late cancellation, court delay, or withdrawal is the key dependency for settlement.[3]
