Toronto Tempo vs. Chicago Sky

Platform comparison

Active sub-markets

Market context

The Toronto Tempo will face the Chicago Sky in a WNBA regular-season matchup on 27 May at 8:00 PM ET. The current 100% implied probability on Polymarket suggests near-certainty in the market's assessment, though this extreme reading warrants scrutiny against comparable venues. Kalshi and Betfair typically display decimal odds formats (where 1.01 would represent this probability), making cross-platform comparison straightforward for traders monitoring line movement. The settlement window closes 28 May at midnight UTC, allowing a single-day window for resolution after the scheduled game time.

Historical WNBA game cancellations remain rare; since the league's expansion, postponements due to weather or scheduling conflicts have occurred, but outright cancellations without rescheduling are exceptional. The 50-50 fallback clause embedded in this market's terms reflects that tail risk, though it has seldom been triggered. Traders comparing Polymarket's fee structure (typically 2% on both sides) against Smarkets' commission model should note that extreme probabilities like 100% YES compress potential returns significantly, making arbitrage opportunities between platforms marginal unless one book prices the event materially differently.

Key variables include roster availability, travel logistics, and any last-minute league announcements. Neither team has reported significant injury concerns as of late May. Traders should monitor official WNBA communications and team social media for any schedule changes; such announcements typically surface 24–48 hours before game time. The absence of current news regarding postponement risk supports the market's high confidence, though the single-day settlement window means late-breaking developments could still trigger the postponement clause.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
