Market outcomes
| Prostejov (Doubles): Kolar/Vocel vs Dias/Silva | 50% YES | 50% NO |
| Completed Match | 50% YES | 50% NO |
A doubles tennis match between Kolar/Vocel and Dias/Silva is scheduled for 2 June 2026 at the Prostejov tournament. The market currently trades at 50% on Polymarket's order book, reflecting genuine uncertainty about which pairing will advance. Settlement occurs on 9 June, allowing a week for the match to conclude; any cancellation, tie, or delay beyond that window triggers a 50-50 resolution.
Prostejov is a lower-tier ATP Challenger event on the European clay circuit, typically attracting mid-ranking professionals and emerging talents. Historical doubles draws at this venue show competitive balance across pairings, with seeding often determining outcomes rather than dominant favourites. The 50-50 implied probability suggests the market perceives both teams as evenly matched, which aligns with typical Challenger-level doubles dynamics where partnership chemistry and recent form matter more than individual ranking points.
Traders should monitor official tournament draws and any late withdrawals, which occasionally occur at Challenger events. Court conditions on clay can shift match dynamics significantly; Prostejov's surface and weather patterns in early June will influence serving effectiveness and rally length. Recent ATP Challenger results for each player's doubles record—particularly their performance on clay in 2026—would clarify whether the current probability reflects actual form or merely structural uncertainty. Any injury announcements or partnership changes in the days before 2 June could shift the order book meaningfully.
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 current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$0 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.

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.
