Cincinnati Open: Coco Gauff vs Marie Bouzkova

Platform comparison

Market context

Coco Gauff is priced as an overwhelming favourite in the contract today, with the market implying a near-certainty that she advances from this Cincinnati Open meeting with Marie Bouzkova. For a Polymarket user, the practical read is straightforward: the contract is already trading at the top end, so the remaining risk is less about pre-match opinion and more about whether the tennis actually takes place and resolves cleanly inside the settlement window.

That framing fits the on-court context. Gauff, the No. 4 seed and 2023 Cincinnati champion, has already worked through Liudmila Samsonova and Ann Li to reach this round, while Bouzkova booked her place by edging Iva Jovic in a tight, straight-sets tiebreak match. Their head-to-head history is competitive enough to matter in theory, but the current price reflects Gauff’s stronger baseline level, the ranking gap, and the fact that she has already handled match pressure in this event this week.

What matters now is scheduling and completion risk. Cincinnati Open women’s play is running from 13 to 23 August 2026, and the market’s settlement rule means a cancellation, a tie, or a delay of more than seven days from the scheduled date would push it to 50-50 rather than a winner. Traders should watch for official order-of-play updates, weather interruptions, retirements, and any rescheduling that could move the match outside the deadline. Under Polymarket mechanics, the contract settles in USDC on Polygon through conditional tokens, so the only thing that changes the outcome is the final on-chain resolution against the event result.

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.
