Market outcomes
| Parma (Doubles): Detiuc/Tang vs Cho/Cho | 50% YES | 50% NO |
| Completed Match | 50% YES | 51% NO |
The Parma doubles draw features Romanian-American pairing Detiuc/Tang against the Cho brothers in a first-round encounter scheduled for 14 May 2026. The match is part of the ATP 250 event on clay, where doubles draws typically feature a mix of established partnerships and emerging combinations. Current order book depth on Polymarket reflects a 50-50 split, suggesting traders perceive genuine uncertainty about which pairing advances to the second round.
Comparable clay-court doubles matchups at this tier show that seeding disparities and partnership chemistry heavily influence outcomes. Unseeded or lower-seeded pairings frequently upset higher-ranked teams on European clay, particularly when one partnership has limited recent tournament history together. Historical data from similar Parma editions indicates that matches between relatively balanced pairings settle near even odds, with the eventual favourite typically emerging only after draw confirmation and pre-match practice court observations become available.
Traders monitoring this market should track official ATP draw confirmations, which typically arrive 48–72 hours before the event. Recent injury reports or late withdrawals from either pairing would shift probability materially. The settlement window extends to 21 May, allowing seven days beyond the scheduled date for completion—a standard buffer for weather delays common on Italian clay courts. Current liquidity on the order book will likely tighten as match day approaches, particularly if either player's form or fitness becomes a talking point in the wider tennis press.
This market settles from the official outcome published at https://www.wtatennis.com/scores. 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 $119 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.
