Cincinnati Open: Amanda Anisimova vs Jessica Pegula

Platform comparison

Market context

The Cincinnati Open match between Anisimova and Pegula is scheduled for 21 August 2026, with the market currently pricing Anisimova's advancement at 46 per cent. No material changes to player status or draw positioning have emerged in the past 48 hours, though both competitors remain active on the WTA circuit heading into the hard-court season.

Pegula holds a 4–2 head-to-head advantage over Anisimova in completed matches, with their most recent encounter occurring at the 2024 US Open where Pegula prevailed in straight sets. Anisimova's win rate against top-20 opponents has fluctuated considerably depending on surface and tournament context; she performs notably stronger on hard courts than clay, which favours her in Cincinnati's conditions. Pegula's consistency in North American hard-court events—where she has reached multiple finals—typically translates to shorter odds in August fixtures. The 46 per cent probability reflects meaningful uncertainty rather than a clear favourite, consistent with how markets price competitive matchups between players ranked in overlapping tiers.

Traders should monitor official Cincinnati Open draw confirmations and any late injury announcements through mid-August. Pegula's performance at preceding summer events will signal her form trajectory, whilst Anisimova's results on hard courts in the weeks before Cincinnati will indicate whether she enters the match with momentum. Weather delays are possible but unlikely to affect settlement given the seven-day grace period built into the market rules.

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.
