| Outcome | Probability |

| Roehampton: Filip Peliwo vs Nicolas Tepmahc | 100% |
| Completed Match | 100% |
Market context
The Roehampton qualifying draw in August 2026 will feature a match between Filip Peliwo and Nicolas Tepmahc, with the winner advancing in the tournament bracket. The fixture is scheduled for 18 August at 08:00 ET, with settlement contingent on a decisive result by 25 August. Current market pricing at 100% YES reflects either extreme confidence in Peliwo's advancement or a data gap where one player's entry status remains unconfirmed—a common pattern in early-stage qualifying draws where late withdrawals or confirmations shift probability sharply.
Qualifying matches at grass-court events like Roehampton historically favour players with established ranking positions and recent match fitness. Peliwo's career trajectory and recent tournament appearances should anchor baseline expectations; comparable qualifying fixtures at British summer events show that seeded or higher-ranked qualifiers convert at roughly 70–75% rates, whilst unseeded matchups exhibit wider variance. If either player has withdrawn or been replaced in the draw since market creation, the 100% reading becomes a settlement-rule edge rather than a genuine probability assessment.
Traders monitoring this market should track official Roehampton draw confirmations and ATP/WTA entry lists through mid-August. Grass-court form in the weeks prior—particularly results from warm-up events—provides concrete data for recalibration. Weather delays are material given the seven-day completion window; rain forecasts for southwest London during that week warrant conditional order adjustments. Integration with live draw APIs and match-status feeds will flag cancellations or postponements triggering the 50-50 resolution clause.
