Market outcomes
| Prostejov (Doubles): Drzewiecki/Matuszewski vs Mrva/Vales | 65% YES | 35% NO |
| Completed Match | 50% YES | 50% NO |
A doubles tennis match between Polish pairing Drzewiecki/Matuszewski and the Czech team Mrva/Vales is scheduled for Prostejov on 2 June 2026. The market currently reflects 65% implied probability for the Polish pair to advance, as priced across Polymarket's order book. Settlement occurs on 9 June, allowing a one-week window for the match to conclude; any cancellation, tie, or unresolved outcome beyond that period triggers a 50-50 resolution.
Prostejov hosts a lower-tier ATP Challenger event, typically attracting players ranked outside the top 100 in doubles. Historical context suggests that Polish doubles combinations have shown modest performance at this level, whilst Czech pairings have demonstrated competitive strength in regional European tournaments. The 65% probability favours Drzewiecki/Matuszewski, suggesting market participants assess them as the stronger pairing, though the 35% counterweight indicates genuine uncertainty about match outcomes at Challenger level, where form variance and court-specific conditions carry substantial weight.
Traders should monitor player injury announcements and withdrawal notices through the ATP official calendar in the days preceding 2 June. Weather conditions at Prostejov—outdoor clay courts are sensitive to rain delays—represent a material risk to the settlement window. Recent scheduling disruptions at Central European Challenger events have occasionally pushed matches beyond the seven-day threshold, which would trigger the 50-50 resolution clause. Confirmation of final draw seeding and any late-round results from qualifying rounds may shift the order book pricing as match day approaches.
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.

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.
$0 in lifetime turnover and $8 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.
