Market outcomes
| WTT - Women's Singles: Rin Mende vs Jia Nan Yuan | 0% YES | 100% NO |
Rin Mende and Jia Nan Yuan are scheduled to meet in a Women's Table Tennis (WTT) singles match on 2 May 2026 at 1:00 PM ET. The current order book on Polymarket shows zero volume at YES, reflecting a 0% implied probability. This extreme positioning suggests either minimal trader interest in the matchup at present, or a technical artefact of early market formation before meaningful liquidity accumulates.
Table tennis prediction markets typically exhibit low trading volumes until 48–72 hours before match time, when player fitness updates, training reports, and draw confirmations drive participation. Mende, a Japanese player, and Yuan, a Chinese competitor, operate within the professional WTT circuit where head-to-head records and recent ranking trajectories heavily influence market sentiment. Historical precedent shows that women's table tennis markets often shift sharply once official tournament brackets are published and player seeding becomes public; current zero probability may simply reflect absence of confirmed scheduling detail rather than consensus view of Mende's chances.
Traders should monitor WTT official announcements regarding final draw confirmation, any withdrawal or injury disclosures from either player, and recent tournament results from both competitors in the weeks preceding 2 May. Court assignments and match order changes can affect player condition on match day. The settlement window closes 2026-05-09 at 17:00 UTC, allowing a seven-day buffer for delayed matches or administrative resolution.
This market settles from the official outcome published at https://www.worldtabletennis.com/. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.

$188 in lifetime turnover and $0 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.
