Market outcomes
| Kosice (Doubles): Karol/Serdarusic vs Mansouri/Neuchrist | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
A doubles tennis match between Karol/Serdarusic and Mansouri/Neuchrist is scheduled for the Kosice tournament on 29 May 2026. The current order book on Polymarket is pricing this event at 100% implied probability for Karol/Serdarusic to advance, reflecting either exceptionally strong conviction about the outcome or minimal liquidity at the current price level. Settlement occurs by 5 June 2026, allowing a seven-day window for the match to conclude.
The 100% pricing suggests either that one pairing is substantially favoured based on recent form and ranking data, or that market participants have not yet engaged meaningfully with this contract. Comparable ATP doubles markets at lower-tier events typically see more balanced pricing when both teams carry legitimate chances, though mismatches between seeding and actual capability do occur. The absence of any probability mass on Mansouri/Neuchrist indicates traders are either confident in the favourite or the market depth remains shallow.
Key variables for traders include confirmation of player availability as the May date approaches, any late withdrawals or injury announcements, and whether either pairing competes in warm-up events beforehand that might shift assessments. The Kosice tournament typically attracts mid-ranking professionals, making form in the weeks immediately preceding the event material to outcome. Traders should monitor ATP tour schedules and official tournament draws once released, as scheduling conflicts or surface-preference mismatches can alter competitive dynamics substantially.
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 "Kosice (Doubles): Karol/Serdarusic vs Mansouri/Neuchrist" are the same as any other PolyGram event contract.

$209 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.
