Market outcomes
| ITF Monastir: Romain Andres vs Matthew Rankin | 33% YES | 67% NO |
| Completed Match | 50% YES | 50% NO |
Romain Andres and Matthew Rankin are scheduled to compete in the ITF Men's Monastir tournament on 3 June 2026. The match represents a lower-tier professional tennis fixture on the ITF circuit, where both players compete for ranking points and prize money. The current order book on Polymarket reflects a 33% implied probability for Andres, suggesting the market views Rankin as the favoured outcome at 67%.
ITF Monastir tournaments typically attract players ranked outside the top 200, with outcomes heavily influenced by recent form, surface adaptation, and head-to-head records. Andres and Rankin's career trajectories on clay courts—the surface used in Monastir—provide context for evaluating the current probability. Players with stronger clay-court records and recent match wins tend to command higher implied probabilities in these markets. The 33% probability for Andres suggests either a historical disadvantage against Rankin, inferior recent form, or lower clay-court credentials relative to his opponent.
Traders should monitor the ITF official website and ATP rankings updates through early June for any withdrawal announcements, injury disclosures, or schedule changes that could affect match timing. Weather conditions in Tunisia during the scheduled window may also influence play, particularly if rain delays occur near the 7 June threshold outlined in the settlement terms. Any official postponement beyond that date without completion would trigger a 50-50 resolution. Current order book depth and bid-ask spreads will indicate whether the 33% probability reflects genuine information asymmetry or thin liquidity in this lower-tier fixture.
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.
