US Open, Qualification ATP: Dalibor Svrcina vs Felipe Meligeni Alves

Platform comparison

Market context

Dalibor Svrčina met Felipe Meligeni Alves in the US Open men’s qualifying first round, with the match listed for Court 15 on 24 August 2026 and the draw showing both players in the qualifying section rather than the main event.[1][2] The market’s 100% YES price is already consistent with a completed result: the event page and live score feeds show the match as finished, which means the key question is not who was favoured pre-match but whether the settlement condition has already been satisfied.[3]

Historically, this is the sort of qualifying fixture where the first-round seed structure matters more than headline ranking gaps. Svrčina was the seeded player in the draw, while Meligeni Alves had the stronger head-to-head record from their previous meeting at US Open qualifying in 2023, when Meligeni Alves won in three sets; that makes a binary “already advanced” read safer for the market than any attempt to infer margin from pre-match odds alone.[1][4] On comparison platforms, Polymarket-style markets show an implied probability directly, while Betfair and Smarkets express the same view through decimal prices and exchange commission, and Kalshi adds US-only access with KYC and a fee layer that can make a near-certain outcome trade less attractive after costs.[5]

For traders, the main catalysts are operational rather than sporting: official score confirmation, any correction to the qualifying draw, and whether the result was posted as a completed match before the settlement window closes on 31 August. US Open qualifying ran on the hard courts at Flushing Meadows in late August, so a cancellation would be unusual, but if a result were annulled or left unresolved by 7 September, the market would revert to 50-50 under its rules.[1][2]
