Market outcomes
| ITF Monastir: Rayen Hermassi vs Alberto Barroso Campos | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Rayen Hermassi faces Alberto Barroso Campos in an ITF Men's tournament match at Monastir, scheduled for 3 June 2026. The 0% implied probability on Polymarket's order book reflects minimal trading activity or positioning on this lower-tier professional tennis fixture. ITF events attract sparse liquidity compared to ATP or Grand Slam markets, and matches between players ranked outside the top 200 often see negligible order book depth, meaning the current probability may simply reflect an absence of committed buyers rather than strong conviction about the outcome.
Historical context for ITF Monastir draws from comparable Tunisian ITF tournaments, where seeding and recent form typically drive results more predictably than at higher professional levels. Hermassi, a Tunisian player, would hold a home-court advantage if competing in Monastir, a factor that has historically shifted win probabilities in ITF events by 8–15 percentage points. Barroso Campos, competing as a visitor, faces the standard travel and acclimation variables affecting lower-ranked touring professionals.
Key catalysts include official tournament draw confirmation and any late withdrawals or illness announcements in the week preceding 3 June. The settlement window extends to 10 June, allowing seven days for rescheduling if weather or other disruptions occur. Traders should monitor ITF official channels and player social media for injury updates, as such announcements frequently precede match cancellations at this level.
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.

The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
