Market outcomes
| Completed Match | 50% YES | 50% NO |
| Prostejov (Doubles): Pokorny/Sachko vs Ayeni/Pavlovic | 51% YES | 50% NO |
A doubles match between Pokorny/Sachko and Ayeni/Pavlovic will take place at the Prostejov tournament on 2 June 2026. The market currently reflects a 50-50 split on Polymarket's order book, indicating genuine uncertainty about which pairing advances. Settlement occurs by 9 June 2026, with a seven-day grace period for delayed matches before defaulting to a split resolution.
Doubles pairings at lower-tier ATP Challenger events like Prostejov typically show tighter odds than singles matches, as team chemistry and serve-return dynamics create more volatile outcomes. Pokorny and Sachko represent a Czech pairing with home-court advantage, whilst Ayeni and Pavlovic bring international composition. Historical data from comparable Challenger doubles draws suggests that seeding differentials and recent partnership durability matter significantly; unseeded or newly formed pairings often trade at wider spreads than established combinations. The current 50-50 probability suggests the market lacks clear information about relative rankings or recent form for these specific players.
Traders should monitor official tournament draws and seeding announcements closer to the event date, as these typically release within two weeks of play. Injury withdrawals or late partnership changes remain a material risk, particularly for lower-ranked Challenger events where roster fluidity is higher. Weather conditions in the Czech Republic during early June could also affect scheduling. Any official tournament communications regarding court assignments or match order will influence order book depth and pricing as the match date 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.
The mechanics for trading "Prostejov (Doubles): Pokorny/Sachko vs Ayeni/Pavlovic" 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.
$0 in lifetime turnover and $2 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.
