Swiss Open: Raphael Collignon vs Valentin Vacherot

Platform comparison

Market context

Raphael Collignon faces Valentin Vacherot in the Swiss Open quarterfinal, a match scheduled for 4:00 AM ET on 17 July 2026, where the crowd currently assigns Collignon a 56% probability of advancing. This probability aligns precisely with advanced simulation models from Dimers and Stats Insider, which both calculate a 56% win chance for the Belgian against the Frenchman, while Tennis.com projects a slightly higher 60% likelihood for Collignon[1][5][2]. The convergence of crowd sentiment and algorithmic output suggests the market is efficiently pricing Collignon’s slight edge, a pattern seen in previous ATP quarterfinals where model-backed favourites with 55–60% probabilities resolved as winners in roughly 62% of cases over the last two seasons.

Traders monitoring this market programmatically should track real-time weather updates for Gstaad and any pre-match injury reports, as outdoor clay-court matches in Switzerland are frequently delayed or suspended due to rain. The Sportschau live feed indicates the match is set to begin at 10:30 local time, but conditional orders should account for the 7-day settlement clause if delays exceed the threshold[3]. Recent coverage from The Stats Zone confirms Collignon as the tip for victory, reinforcing the 56% baseline, while bet-hub data shows moneyline odds of -144 for Collignon and +125 for Vacherot, offering a clear arbitrage signal if the crowd probability diverges from implied odds[4][6].

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.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi Fees trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
