Market outcomes
| ITF Monastir: Yacoub Makzoume vs Marcello Serafini | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Yacoub Makzoume faces Marcello Serafini in the ITF Men's tournament at Monastir, scheduled for 3 June 2026. The current order book on Polymarket prices Makzoume's advancement at 16% implied probability, reflecting substantial backing for Serafini among active traders. This pricing emerges from real-time order flow rather than consensus forecasting, meaning the spread between bid and ask prices reveals where marginal traders currently stand on the matchup.
Makzoume, a Moroccan player, and Serafini, an Italian competitor, operate within the ITF circuit where ranking points and tournament structure differ markedly from ATP events. Historical ITF matchups between players of comparable ranking typically show favourites winning 65–75% of the time, though upsets occur more frequently at lower-tier events than on the professional tour. The 16% probability assigned to Makzoume suggests traders view Serafini as a clear favourite, possibly reflecting recent form data, head-to-head records if available, or surface preference on clay courts at Monastir.
Traders should monitor official ITF announcements regarding player withdrawals or injury updates in the week preceding 3 June, as such developments frequently shift market pricing on lower-tier matches. Confirmation of both players' participation and any last-minute schedule changes will be critical; the settlement window extends to 10 June to account for potential delays. Court conditions and weather forecasts for Monastir during the tournament week may also influence trading activity as match day approaches.
This market settles from the official outcome published at https://www.itftennis.com/en/tournament-calendar/. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
