Seattle Storm vs. Toronto Tempo

Active sub-markets

Market context

The Seattle Storm face the Toronto Tempo on 30 May 2026 at 1:00 PM ET in a regular-season WNBA matchup. Settlement occurs at 17:00 UTC the same day, allowing roughly sixteen hours post-game for final score confirmation and market resolution. The 0% implied probability suggests either a data error, extreme confidence in one outcome, or insufficient liquidity at current odds—conditions worth stress-testing before committing capital.

Historical WNBA game cancellations remain rare; since 2020, postponements have typically resulted from weather or health protocols rather than outright cancellations. The 50-50 fallback clause matters primarily for conditional order logic: traders automating hedges or cascading bets should flag the cancellation scenario as a tail risk requiring explicit handling. Reviewing the WNBA's 2026 schedule and any venue-specific contingencies (climate, facility status) provides baseline context for assessing true game-day execution risk.

Traders monitoring this market programmatically should track roster updates, injury reports, and travel logistics in the week preceding tip-off. Recent WNBA injury announcements typically surface via official league channels and team social media 24–72 hours before games. For conditional order strategies—such as backing one team only if a key player clears health protocols—setting alerts on official WNBA injury reports and cross-referencing against live odds feeds will flag meaningful shifts before market repricing. Postponement risk, whilst low, justifies a small position buffer if using this market as a hedge component within a broader portfolio.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
