Market outcomes
| WTT - Women's Singles: Croatia vs Japan | 0% YES | 100% NO |
A Women's Singles table tennis match between Croatia and Japan is scheduled for 4 May at 5:00 AM ET as part of a WTT event. The current order book on Polymarket reflects a 0% implied probability for a Croatian victory, indicating that traders are pricing Japan as the overwhelming favourite. This extreme skew suggests either substantial confidence in Japan's superiority or minimal trading activity establishing a floor price.
Japan has established itself as a dominant force in women's table tennis, with multiple players ranked in the world's top 50 and consistent performances across international competitions. Croatia, whilst competitive at European level, has historically struggled to produce players capable of challenging Asia's elite. Previous matchups between these nations at comparable events have typically favoured Japan, and the current probability distribution aligns with this historical pattern. However, 0% pricing is unusual in sports markets and often reflects thin liquidity rather than absolute certainty.
The settlement window closes on 11 May at 09:00 UTC, providing a six-day buffer beyond the scheduled match date. Traders should monitor WTT's official fixture confirmations and any player injury announcements in the days preceding the match, as withdrawals or postponements could trigger the 50-50 tie-break resolution. Recent WTT scheduling has remained stable, though weather or logistical disruptions occasionally affect early-morning fixtures. The extreme current pricing leaves room for modest position-building if new information emerges regarding player fitness or draw changes.
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.
The mechanics for trading "WTT - Women's Singles: Croatia vs Japan" are the same as any other PolyGram sporting 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.
$20 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.
As of today, traders on Polymarket price this outcome at 0%. The number updates continuously as the order book clears. PolyGram mirrors the same live odds with locale-aware formatting and USDC settlement.
