Estoril Open: Andrey Rublev vs Luca Van Assche

Platform comparison

Market context

Polymarket is pricing this contract at **83% YES** today, which implies the market expects Andrey Rublev to advance against Luca Van Assche in the Estoril Open quarter-final. On Polymarket, the position is held through **USDC** on **Polygon**, with the outcome determined by the match result or, if the fixture is not completed under the market rules, the contract’s conditional-token settlement path.

That pricing sits above most external pre-match models but not by a huge margin. String Tension’s Elo model gives Rublev about **75.1%** to win, while recent preview pieces also lean his way, including predictions for a straight-sets result and quoted moneyline odds that make Rublev a clear favourite.[1][2][3][5] The gap between the on-chain price and the model range suggests traders are paying up for a strong favourite, but still leaving room for a live upset if the match is tighter than expected.

The main catalyst is simple: whether the match starts on schedule and whether Rublev’s level matches the market’s expectation once play begins. The listed start time is around **12:10 UTC** at Millennium Stadium, and the market only resolves to **50-50** if the match is cancelled, ends level, or is delayed beyond seven days without a winner.[6][8] For a Polymarket user, that means the key checks are tournament scheduling updates, any late withdrawal news, and whether the quarter-final is actually completed rather than merely begun, because incomplete matches can still trigger the market’s fallback settlement rules.

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

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.
