Market context
Radu Albot and Constantin Bittoun Kouzmine are scheduled to meet at Roehampton on 18 August 2026, with the match originally set for 9:00 AM ET. The 100% implied probability for Albot reflects significant disparity in their competitive profiles. Albot, a Moldovan ranked in the ATP's upper tier, has competed consistently at Challenger and ATP level across multiple surfaces. Bittoun Kouzmine, a French player, operates primarily on the Challenger circuit and lower-tier professional events. The gap in tour experience and ranking points typically favours Albot in direct matchups, though Roehampton's grass surface introduces variables that merit scrutiny.
The settlement window closes on 25 August, allowing a seven-day buffer beyond the scheduled date. Traders should monitor official tournament draws and any weather delays affecting the grass-court schedule at Roehampton, as the venue's outdoor courts are susceptible to rain interruptions common to August in south-west London. Confirmation of both players' participation in the event remains essential; late withdrawals or injury declarations would trigger the 50-50 resolution clause. Recent form data and head-to-head records between these competitors are sparse at professional level, suggesting limited prior direct encounters. Any announcement regarding surface conditions, court assignments, or scheduling changes should be tracked through the ATP and tournament organisers' official channels.

FAQ
- 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.
- Which sports markets are available?
- Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.
- 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.
