Market outcomes
| Vicenza (Doubles): Ruehl/Veldheer vs Navarro/Lopez | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Ruehl and Veldheer face Navarro and López in a doubles match at the Vicenza tournament on 28 May 2026. The current order book on Polymarket reflects a 100% implied probability for Ruehl/Veldheer, suggesting the market has priced them as heavy favourites or that liquidity constraints are driving the extreme reading. Settlement occurs on 4 June 2026, allowing a week-long window for the match to conclude; any cancellation, tie, or delay beyond seven days triggers a 50-50 resolution.
Historical doubles matchups at Vicenza typically favour established partnerships with recent tournament experience. Ruehl and Veldheer's seeding relative to Navarro and López, along with their recent ATP or Challenger doubles records, would normally anchor the probability distribution. The 100% reading suggests either the market has absorbed significant information about one team's withdrawal, injury, or overwhelming form advantage, or that the order book lacks sufficient depth to reflect genuine uncertainty.
Traders should monitor official tournament announcements through the ATP or Vicenza organisers' channels for any withdrawal notices, schedule changes, or surface condition updates that could affect match play. Injury reports on any of the four players in the days preceding 28 May would be critical catalysts. The seven-day delay clause creates a specific risk: if weather or other disruptions push the match beyond 4 June without completion, the market resolves to 50-50 regardless of match state, which could significantly alter expected value for positions taken at current odds.
This market settles from the official outcome published at https://www.atptour.com/en/scores/current. 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 mechanics for trading "Vicenza (Doubles): Ruehl/Veldheer vs Navarro/Lopez" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$252 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.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
