US Open, Qualification ATP: Luca Nardi vs Federico Cina

Platform comparison

Market context

Polymarket has this contract pinned at 0% YES, which means the market is treating Luca Nardi’s advance as effectively impossible at the moment. On Polymarket, the position is settled in USDC on Polygon through conditional tokens, so the live price reflects what traders think is left of the chance that Nardi wins this qualifying match, not the scoreline itself.

The real-world anchor is the US Open men’s qualifying first round between two Italians, originally scheduled for 25 August at Court 13 in New York. A comparable read on these markets comes from the gap between a 0% print and the underlying event still being live or unresolved: if the match is delayed, interrupted, or later marked unfinished before the resolution deadline, the contract can still move away from a pure winner-take-all outcome.

The main catalysts are straightforward: whether the match was completed, whether either player withdrew, and whether the official draw and schedule remain unchanged. Recent listings showed the pair set for qualifying play, while later reporting indicated Nardi retired and Cinà advanced after a knee issue, which would normally settle the market towards Federico Cina if reflected in the final official result. Traders still watch for tournament updates, walkovers, and any correction to the published order of play, because those are the events that determine whether the contract resolves to one side or to 50-50 if no winner is established by the deadline.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
