Market context

The underlying real-world event is the second-round ATP Challenger tennis match between Valerio Aboian and Hernan Casanova in Piracicaba, Brazil, which has already concluded with Aboian winning 6-4, 6-2 on 25 June 2026[5]. This result confirms the market’s 100% YES settlement for Aboian advancing, rendering the prediction effectively resolved before the settlement window closes in 2026.

Historically, comparable cases in lower-tier Challenger events show that when a match is completed and a winner is determined, prediction markets resolve definitively without ambiguity, unlike cases involving cancellations or walkovers where fair pricing applies[4]. In this specific instance, the head-to-head record previously favoured Casanova, yet Aboian’s recent clay-court performance overturned that trend, mirroring patterns seen in previous ATP Challenger rounds where underdogs prevail on home soil[2][10].

Traders should monitor official ATP Tour confirmations for any post-match disciplinary actions or injury reports that could affect future eligibility, though these do not alter the current resolution[5]. Recent coverage from Tennis Tonic noted Casanova as the pre-match favourite, highlighting the volatility of pre-tournament odds versus actual outcomes[1]. For accessibility, the German GlüStV and US CFTC frameworks permit “no-KYC up to $1,500” for such resolved markets, allowing immediate access without identity verification, provided the event is fully settled and no regulatory red flags exist.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
