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

Platform comparison

Market context

Dalibor Svrcina and Felipe Meligeni Alves met in the US Open men’s qualifying first round on 24 August, with the match listed at Court 15 and later shown as finished 6-3, 6-4 to Svrcina. The market’s 100% yes price is consistent with the result already appearing in live scoreboards and tournament draw pages, leaving little room for uncertainty unless the market is waiting on formal settlement timing rather than the on-court outcome. [1][2][3]

For framing, Svrcina had the clearer ATP ranking edge pre-match, and the draw placed him as the higher seed in this section, which made him the more straightforward favourite before play started. The pair had also met before in US Open qualifying, with Meligeni Alves winning their 2023 meeting, so the head-to-head did not point to an automatic repeat, but the live market still leaned heavily on Svrcina’s stronger ranking and recent form. [4][5][6]

The main catalyst to watch is not a polling swing but the official match status and whether the result is recorded as completed within the settlement window. US Open qualifying schedules and scoreboards showed the fixture as played on 24 August, and contemporary tennis coverage listed it as a straight first-round qualifying match, so any residual risk sits with administrative settlement rather than a missing contest.

UK Frequently Asked Questions

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
