Market outcomes
| Prostejov (Doubles): Klimas/Vagner vs Karol/Paulson | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
A doubles tennis match between Klimas/Vagner and Karol/Paulson is scheduled for 1 June 2026 at the Prostejov tournament. The current order book on Polymarket shows a 0% implied probability for Klimas/Vagner advancing, reflecting either strong conviction that Karol/Paulson will prevail or minimal trading activity establishing a floor price. With settlement occurring by 8 June 2026, the market has a narrow window to reflect pre-match conditions and any late developments.
Doubles pairings at lower-tier ATP and ITF events often show volatile form, particularly when partnerships are newly formed or players are stepping up in competition level. Historical precedent suggests that 0% probabilities in tennis markets typically indicate either a significant ranking or seeding disparity, recent poor form from the underdog pairing, or simply illiquid order books where no trader has yet tested the bid-ask spread. Without established head-to-head records between these specific pairings, the probability likely reflects the individual players' recent doubles results and tournament seeding rather than match-specific intelligence.
Traders should monitor official Prostejov draw confirmations and any withdrawal announcements through the ATP or tournament website in the days preceding 1 June. Late scratches or partner substitutions are material catalysts at smaller events. Additionally, the resolution clause specifying a 50-50 outcome if the match is delayed beyond seven days without completion introduces tail risk; weather disruptions at Central European venues in early June warrant consideration. Any shift in the order book would signal fresh information entering the market.
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 "Prostejov (Doubles): Klimas/Vagner vs Karol/Paulson" 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.
$220 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.
