Market outcomes
| Centurion 2 (Doubles): Bertrand/Dalmasso vs Santillan/Zheng | 50% YES | 50% NO |
| Completed Match | 62% YES | 39% NO |
A doubles match between Bertrand/Dalmasso and Santillan/Zheng is scheduled for the Centurion 2 tournament on 2 June 2026 at 05:00 ET. The market currently reflects a 50–50 split on Polymarket's order book, indicating genuine uncertainty about which pairing will advance. Settlement occurs on 9 June, allowing a seven-day window for the match to complete; any cancellation, tie, or delay beyond that threshold triggers a 50–50 resolution.
Doubles outcomes at lower-tier professional events typically hinge on serve consistency and net play rather than individual ranking pedigree. Historical precedent suggests that unseeded or mixed-ranking pairings often perform unpredictably, particularly when one player carries significant singles form and the other specialises in doubles. The current 50–50 pricing reflects this inherent volatility rather than a clear favourite emerging from recent head-to-head records or ranking composites.
Traders should monitor tournament draw confirmations and any late withdrawals in the days preceding 2 June. Surface conditions at the Centurion venue—typically hard court—favour aggressive serve-and-volley styles, which may advantage one pairing depending on player profiles. Injury updates or scheduling conflicts affecting either team remain the primary catalyst for repricing before the match begins. The settlement window's seven-day buffer provides sufficient time for completion unless weather or logistical disruptions occur.
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 $1 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.
