Swiss Open: Pedro Martinez vs Yannick Hanfmann

Platform comparison

Market context

Pedro Martinez and Yannick Hanfmann are scheduled to meet in the first round of the Swiss Open on 13 July 2026. The 30% implied probability for Martinez reflects a matchup where Hanfmann enters as the favoured player, though neither competitor ranks among the tour's elite. Recent ATP rankings and tournament seedings will clarify the official designation once draw confirmation arrives in early July; any shift in either player's form or injury status in the fortnight before the event could move the probability meaningfully.

Hanfmann has historically performed well on European clay and grass surfaces, whilst Martinez has shown inconsistent results against top-100 opposition. Head-to-head records between lower-ranked players often matter less than recent tournament performance and surface suitability. The Swiss Open's grass courts favour aggressive serving and net play—a factor that typically advantages players with strong first-serve percentages and volley technique. If either player's recent warm-up results (Wimbledon qualifying or other pre-Swiss events) show notable form shifts, traders should expect probability adjustments.

The settlement window extends to 20 July, providing a seven-day buffer beyond the scheduled date. Traders should monitor official Swiss Open announcements for draw confirmation, any weather-related delays, or last-minute withdrawals. Injury reports from either player's team in the week before 13 July represent the primary catalyst for significant repricing. The grass-court season's compressed schedule means both players will likely compete in multiple events simultaneously, so fatigue or minor injury management could influence match outcomes.

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.
