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

Platform comparison

Market context

Dalibor Svrcina’s qualification match with Felipe Meligeni Alves at the US Open was scheduled for Court 15 in the men’s qualifying draw, with the official draw placing Svrcina at No 8 and Meligeni Alves just below him in the bracket.[12][13] In a market already pricing 100% YES, that kind of setup is best read as a post-event placeholder rather than a live probability: once a first-round qualifying match is listed and then completed, the resolution path is normally binary, while any non-played outcome pushes the market towards the 50-50 fallback by the settlement rules.

The useful comparison case for programmatic traders is simple draw-state handling: once the match is marked finished on live-score feeds, the bot should stop treating schedule risk as active and instead switch to result-confirmation logic, cross-checking the winner across the draw PDF, live scores, and any scoreline aggregator before allowing a final position or auto-settlement. Recent listings also show the match was placed alongside the wider 24–27 August men’s and women’s qualifying window, so the main dependency is whether the Court 15 slot actually converted into an official completed result within the settlement period.[11][1][3]

The practical catalysts to watch are match-status updates, any court reassignment, and whether the scoreline is recorded as a completed advancing result before 7 September 2026, 11:59 PM ET. For tooling, the clean workflow is to set an order or alert on the event ID, monitor live completion flags rather than pre-match odds, and only trigger a directional answer when the official draw and score feed agree; if the fixture is abandoned or never formally completed, the market rule sends it to 50-50.
