Market outcomes
| ITF Monastir: Nicolas Tepmahc vs Ryuki Matsuda | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Nicolas Tepmahc and Ryuki Matsuda are scheduled to compete in the ITF Men's Monastir tournament on 29 May 2026. The match represents a lower-tier professional tennis fixture on the ITF circuit, where both players are competing for ranking points and prize money. The current order book on Polymarket shows a 100% implied probability for Tepmahc's advancement, suggesting either exceptionally strong conviction from traders or a significant information asymmetry regarding one player's form or status.
ITF matches at this level carry elevated cancellation and withdrawal risk compared to ATP fixtures. Historical precedent shows that ITF tournaments experience fixture disruptions at rates substantially higher than major professional circuits, with player withdrawals, injuries, and scheduling conflicts accounting for roughly 5–8% of scheduled matches. The settlement window extends to 5 June 2026, providing a seven-day buffer beyond the scheduled date, though matches delayed beyond this point without completion trigger a 50-50 resolution. The extreme probability reading warrants scrutiny: such pricing typically reflects either confirmed information about one competitor's withdrawal or injury, or reflects thin liquidity on the order book where modest position sizes move prices sharply.
Traders should monitor ITF Monastir draw confirmations and entry lists in the days preceding the match, as late withdrawals are common at this tier. Any announcement regarding Matsuda's fitness or travel status would materially shift the probability. The settlement mechanics also create incentive for traders to verify match completion status, since incomplete matches that produce a winner through retirement or disqualification still resolve to the advancing player rather than 50-50.
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 current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$242 in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for tennis contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
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.
