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

Platform comparison

Market context

Polymarket prices this contract at 100% YES, which implies the market is treating Dalibor Svrcina’s advancement as fully locked in. On the platform, the position is a USDC-settled conditional token on Polygon, so the only thing that matters at resolution is whether the ATP qualifying match produces a winner before the deadline; if it is not played, is tied, or remains undecided by 7 September, it falls back to 50-50.

The event itself is a US Open qualifying match in New York between Svrcina and Felipe Meligeni Alves, originally listed for 24 August 2026 on Court 15. Comparable qualifying markets can look one-sided once a live scoreline or final result confirms the favourite has progressed, but they can still reprice quickly if a delay, walkover, retirement or scoreboard mismatch leaves the outcome formally unsettled.

For traders, the key catalyst is straightforward: official draw, order-of-play and scoreboard updates from the tournament and score providers. The US Open qualifying schedule runs across 24–27 August, with men’s singles qualifying on the opening days and the final qualifying round on Thursday, so the main dependency is whether this match is confirmed, completed and recorded as a decisive advance before the resolution window closes.
