Market outcomes
| ITF Pensacola: Ryan Haviland vs Dan Martin | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Ryan Haviland and Dan Martin are scheduled to compete in the ITF Men's Pensacola tournament on 13 May 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 shows zero volume at any price level, with the implied probability reflecting no meaningful market activity or consensus positioning ahead of the settlement window closing on 20 May.
ITF Men's matches at this tier typically feature players ranked outside the ATP top 200, where form and injury status shift rapidly between tournaments. Historical precedent suggests that matches involving players with limited recent ATP or Challenger exposure often settle based on head-to-head records, surface preference, and recent tournament results rather than pre-match sentiment. The 0% probability reading reflects the absence of trading interest rather than certainty about either player's prospects; such extreme prices commonly appear in niche sports markets where liquidity remains thin until closer to event dates.
Traders monitoring this fixture should track ITF tournament draws and any withdrawal announcements from the official ITF website, as cancellations or schedule delays are material risks given the settlement rule allowing 50-50 resolution if the match extends beyond seven days without completion. Recent injury reports or late-stage withdrawals from either player would shift the probability substantially once trading begins. Current market inactivity suggests opportunity for informed traders with access to player fitness data and recent performance records on hard courts.
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.
