Wimbledon ATP: Vit Kopriva vs Jan Choinski

Platform comparison

Market context

The underlying real-world event is the Wimbledon ATP men’s singles match between Vit Kopriva and Jan Choinski, originally scheduled for 29 June 2026 at 6:00 AM ET but now set to begin on 30 June at 18:00 Moscow time [3][7]. This market currently shows a crowd-implied probability of 0% for Kopriva advancing, a stark divergence from analytical models that assign him a 59–60.5% win probability [1][2]. Historically, in their head-to-head record, Choinski holds a 2–1 advantage in ATP matches, though Kopriva is favoured by Tennis Tonic and Dimers to win this encounter in five sets [1][2]. In broader simulations since 2023, Choinski has won 85.7% of their nine games, yet recent ATP form and initial odds point to Kopriva as the value pick [4][1].

Traders should monitor the official match start confirmation and any injury updates before play, as delays beyond seven days without a winner trigger a 50–50 resolution [1]. Choinski’s higher ATP ranking (106 vs 68) and physical stature (196 cm vs 178 cm) may influence surface performance, but Kopriva’s recent pick status suggests contrarian value [1][6]. With odds at -160 for Kopriva and +135 for Choinski, the consensus leans Choinski despite model favouring Kopriva, creating a potential mispricing [2]. No recent news source has altered the pre-match landscape, so the key catalyst remains the live start and first-set momentum [3]. The 0% crowd probability likely reflects a data lag or crowd bias, not a genuine shift in player form.

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.
