Market outcomes
| Kosice (Doubles): Bass/Clarke vs Mansouri/Neuchrist | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Bass and Clarke face Mansouri and Neuchrist in a doubles match at the Kosice tournament, scheduled for 26 May 2026. The current order book on Polymarket shows zero probability for Bass/Clarke advancing, reflecting either minimal trading activity on this specific pairing or strong market conviction favouring the opposing team. At this early stage before the event, such extreme probabilities often indicate thin liquidity rather than definitive forecasting power, particularly for lower-profile doubles matches outside the Grand Slam circuit.
Comparable ATP and WTA doubles pairings at secondary tournaments typically see modest trading volumes, with probabilities shifting materially only as match dates approach and player form becomes clearer. Historical precedent suggests that doubles outcomes depend heavily on recent partnership cohesion, surface preference, and head-to-head records. Bass and Clarke's current ranking and recent results against Mansouri and Neuchrist would be critical reference points; if either pairing has limited recent tournament exposure together, the market's confidence level should be treated with caution.
Traders should monitor player injury announcements and tournament draw confirmations through May, as the Kosice event sits within the broader European clay-court season. Any withdrawal or late substitution could trigger resolution under the tie/cancellation clause. Recent ATP and WTA scheduling updates typically appear on official tour websites and player social media accounts. The settlement window closes 2 June 2026, allowing roughly one week post-match for completion, though delays beyond that trigger a 50-50 resolution.
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): Bass/Clarke vs Mansouri/Neuchrist" are the same as any other PolyGram sporting 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.
$5 in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for sports 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.
