Market outcomes
| Oeiras 4 (Doubles): Liutarevich/Pieczonka vs Bayldon/Veldheer | 50% YES | 50% NO |
| Completed Match | 50% YES | 51% NO |
A doubles tennis match between Liutarevich/Pieczonka and Bayldon/Veldheer is scheduled for 14 May 2026 at the Oeiras 4 tournament, with the settlement window closing on 21 May. The current order book on Polymarket reflects a 50-50 split, indicating traders assess both pairings as evenly matched on available information. This even pricing typically emerges when historical head-to-head records are sparse, player form data is limited, or recent ranking movements have not yet been fully priced in by the market.
Doubles outcomes depend heavily on partnership chemistry and recent tournament performance. Liutarevich and Pieczonka's record as a pairing, their individual doubles rankings, and any recent results from ATP or ITF events will inform whether either team has a demonstrable edge. Similarly, Bayldon and Veldheer's recent tournament appearances and win rates in doubles competition provide concrete reference points. Traders should monitor official ATP or tournament draws released closer to the event date, as late withdrawals or substitutions can shift probabilities significantly.
The settlement window extends seven days beyond the scheduled match date, meaning delays within that window still resolve to a winner. Cancellations, ties, or delays exceeding seven days trigger a 50-50 resolution. Weather disruptions at the Oeiras venue or player injury announcements in the days before 14 May would be key catalysts affecting the order book's pricing.
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.

$0 in lifetime turnover and $135 of resting liquidity puts this market in the below the median by volume for games 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.
