Market outcomes
| Washington Mystics vs. Toronto Tempo | 100% YES | 0% NO |
The Washington Mystics face the Toronto Tempo on 8 May at 19:30 ET in a regular-season WNBA matchup. The current order book on Polymarket reflects a 100% implied probability for the Mystics, indicating near-certainty among traders that Washington will emerge victorious. This extreme skew suggests either substantial confidence in the Mystics' superiority or minimal liquidity at the extremes of the book, a common feature in niche sports markets where participation remains concentrated.
Historical WNBA matchups between established franchises and expansion teams typically show wide probability spreads, though the Toronto Tempo's inaugural 2024 season performance will inform expectations. The Mystics, a franchise with established roster depth and playoff experience, would ordinarily command favourability, yet a 100% probability leaves no room for variance—injuries, unexpected performance swings, or statistical outliers that occur regularly in professional sport.
Traders should monitor roster announcements through early May, particularly any late injury reports affecting either team's starting lineup. The settlement window closes at 23:30 ET on 8 May, allowing for game completion and official scoring. Postponement would extend the market's duration, whilst cancellation without rescheduling would trigger a 50-50 resolution. Current market depth and whether additional liquidity emerges at alternative price points will determine whether this extreme probability holds or adjusts as game day approaches.
This market settles from the official outcome published at https://www.wnba.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 "Washington Mystics vs. Toronto Tempo" 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.
$100K in lifetime turnover and $0 of resting liquidity puts this market in the top 30% by volume for wnba contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
Last 24 hours alone saw $70K in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.
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 100%. The number updates continuously as the order book clears. PolyGram mirrors the same live odds with locale-aware formatting and USDC settlement.

Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
