Cincinnati Open: Amanda Anisimova vs Jessica Pegula

Platform comparison

Market context

Amanda Anisimova and Jessica Pegula are scheduled to meet in the second round of the Cincinnati Open on 21 August 2026. The 46% implied probability for Anisimova reflects a slight favourite position for Pegula, though the gap remains narrow enough to suggest meaningful uncertainty about the outcome. Settlement occurs on 28 August, allowing a seven-day window for completion; any cancellation, tie, or unresolved delay beyond that threshold triggers a 50-50 resolution.

Head-to-head records between these players show competitive balance. Pegula holds a marginal advantage in their recent encounters, though Anisimova has demonstrated capacity to compete at the highest level when serving well and controlling baseline rallies. Pegula's consistency on hard courts—her preferred surface—typically translates to stronger performances in North American summer tournaments. Historical Cincinnati Open data suggests first-round exits and early-round upsets occur frequently enough that seeding alone does not determine outcomes; surface conditions and match-day form carry substantial weight.

Traders should monitor first-round results for both players, scheduled immediately before this fixture. Injury reports or withdrawal announcements in the days preceding 21 August would alter settlement prospects materially. Recent WTA rankings fluctuations and any late-tournament scheduling changes announced by the Cincinnati organisers warrant attention. Sportsbook lines from major operators (DraftKings, FanDuel, Betfair) should be cross-referenced against the 46% figure; divergences exceeding 3–4 percentage points may indicate market inefficiency or information asymmetry worth investigating.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
