Wimbledon WTA: Jessica Pegula vs Coco Gauff

Platform comparison

Market context

Jessica Pegula faces Coco Gauff in the Wimbledon Women’s Singles quarter-final on Tuesday, 7 July 2026, with Pegula currently favoured to advance. The crowd-implied probability sits at 61% YES for Pegula, while Stats Insider’s predictive model assigns her a 58% chance, and TAB prices her at $1.61 against Gauff’s $2.30[1]. Historically, Pegula leads the head-to-head 5-3, having won both of their tight encounters, including a three-set victory at the 2025 WTA Finals[3][4]. On grass, the pair are evenly matched with one win each, suggesting the surface offers no clear edge, yet Pegula’s consistency in decisive moments has repeatedly tipped the balance in their favour[10].

Traders should monitor pre-match announcements regarding player fitness, as Gauff needed a deciding-set tiebreak to survive her second-round opponent, raising questions about her stamina[6]. The consensus leans heavily toward Pegula, but value may exist on Gauff at the current odds, particularly if the market overweights Pegula’s historical dominance without accounting for Gauff’s recent resilience. Contrarian angles could focus on total games, with bet365 offering Over 22.5 at -120, reflecting the likelihood of a competitive, multi-set contest[3]. Kalshi’s 57-cent contract for Pegula at -133 American odds equivalent presents a discounted entry point compared to standard sportsbooks pricing her at -163[3].

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.

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 does Polymarket cost to trade?
