Market outcomes
| Completed Match | 50% YES | 50% NO |
| Centurion 2 (Doubles): Montsi/Schalkwyk vs Peliwo/Zhu | 50% YES | 50% NO |
The Centurion 2 doubles match between Montsi/Schalkwyk and Peliwo/Zhu is scheduled for 3 June 2026 at 6:00 AM ET. The market currently reflects a 50-50 split on Polymarket's order book, indicating genuine uncertainty amongst traders regarding which pairing will advance. This even probability suggests neither team commands a clear advantage in the eyes of active participants, with both sides of the order book receiving comparable backing at current price levels.
Doubles tennis outcomes depend heavily on partnership cohesion, recent form, and head-to-head records. Montsi and Schalkwyk's previous performances together, alongside Peliwo and Zhu's track record as a unit, would typically inform baseline expectations. The Centurion tournament has historically featured competitive draws with unpredictable results, particularly in doubles where seeding often fails to predict outcomes. Comparable early-round doubles matches at similar-tier events have shown that unseeded or lower-ranked pairings frequently upset expectations, which may explain why the market has settled at parity rather than favouring the higher-ranked combination.
Traders should monitor official tournament draw confirmations and any late withdrawals or substitutions, which remain possible until match day. Injury reports or scheduling changes affecting either pairing could shift the order book materially. The settlement window closes 10 June 2026, allowing a week for the match to be completed; any cancellation or failure to produce a winner within that timeframe triggers a 50-50 resolution, which is already priced into current market sentiment.
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 "Centurion 2 (Doubles): Montsi/Schalkwyk vs Peliwo/Zhu" are the same as any other PolyGram 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.
$0 in lifetime turnover and $12 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.
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.
