Market context
Arthur Fery and James Duckworth were due to meet in the Cincinnati Open second round on outdoor hard courts, with Fery having had the bye and Duckworth arriving off a straight-sets first-round win over J.J. Wolf. The current 100% yes price looks like a firm expectation that the match will be played, but the settlement rules still leave room for a push to 50-50 if the fixture is postponed beyond the seven-day window or never starts.
The form line gives Fery the cleaner recent profile. He has put together a strong 2026 hard-court season and arrived in Cincinnati with momentum, while Duckworth’s recent results have been more mixed even though he has already banked a win at the event. Their prior meetings also matter: the matchup has been one-way enough to support Fery as the more likely advance, which helps explain why pre-match models have generally leaned his way.
For traders, the key catalysts are the live schedule and any late court assignment changes, because this was originally set for 15 August and still sits inside a narrow settlement window. Any medical timeout, withdrawal, or rain-related slippage would be material given the market rules, and the only real surprise would be a delay that pushes the match beyond 22 August without a winner.

FAQ
- Are prediction markets better than sports betting?
- Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.
- When do sports markets resolve?
- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- What's the difference between match odds and outright odds?
- Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
- Can I import form data and lineups?
- This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
