Ilkley: Filippo Romano vs Jack Pinnington Jones

Active sub-markets

Market context

The Ilkley tournament in West Yorkshire hosts a grass-court ATP 250 event each June, drawing mid-ranking professionals competing for ranking points before the Wimbledon fortnight. Filippo Romano, an Italian player ranked outside the top 200, faces British qualifier Jack Pinnington Jones in what is scheduled as an early-round match on 11 June 2026. A YES share represents a bet that Romano advances; a NO share bets on Pinnington Jones progressing. The market currently shows 100% implied probability for YES, meaning traders have priced in an expectation of Romano's victory with near-certainty.

Grass-court results at Ilkley have historically favoured British players and those with recent match fitness, though upsets remain common in qualifying and early rounds. Pinnington Jones, competing on home soil, typically draws crowd support that can influence momentum in tight sets. Romano's recent form and seeding status relative to his opponent will be the primary determinants; if either player withdraws due to injury or illness before the match, or if the fixture is postponed beyond seven days without completion, the market resolves to a 50-50 split rather than declaring a winner.

Traders should monitor official ATP and Ilkley tournament announcements for withdrawal notices, weather delays affecting the grass courts, or schedule changes in the week preceding the match. Injury reports on both players' fitness in the days leading to 11 June will be critical signals, as will any late draws or seeding adjustments published by the tournament organisers.

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.
