Market outcomes
| Birmingham (Doubles): Jones/Paris vs Ho/Jebens | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
A doubles tennis match between Jones/Paris and Ho/Jebens is scheduled for the Birmingham tournament on 2 June 2026 at 5:00 AM ET. The market currently reflects a 100% implied probability for Jones/Paris to advance, as shown across Polymarket's order book. This extreme probability typically emerges when one pairing is substantially favoured based on ranking, recent form, or head-to-head record, though such certainty in tennis doubles remains unusual given the format's inherent volatility.
Doubles markets at major tournaments historically show wide probability ranges even for seeded pairings, as injury withdrawals, court conditions, and momentum shifts can shift outcomes sharply. The 100% reading here suggests either a significant ranking or seeding advantage for Jones/Paris, or possibly that Ho/Jebens entered the draw as qualifiers or lower-ranked players. Comparable ATP and WTA doubles fixtures rarely trade at such extremes unless one team has withdrawn or a substantial news event has altered expectations materially.
Traders should monitor official Birmingham tournament draws and any injury announcements through the ATP or WTA websites through the settlement window closing 9 June 2026. Court surface conditions at Birmingham's grass courts can favour certain playing styles, and late withdrawals remain a material risk given the compressed professional calendar. The seven-day delay clause means matches must conclude by 9 June to avoid a 50-50 resolution, creating a hard deadline for completion.
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.

$48 in lifetime turnover and $0 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.
