Chicago Sky vs. Atlanta Dream

Platform comparison

Market context

The Chicago Sky and Atlanta Dream faced off in a WNBA contest on 19 July 2026, where the Dream secured a 93–91 victory after Jordin Canada’s buzzer-beating layup sealed the win [1]. In prediction markets, a YES share pays out if the market’s condition is met—here, if the Chicago Sky win—while a NO share pays out if they do not. With the game already completed and the Dream victorious, the market’s current 0% YES probability correctly reflects that the Sky did not win, making a YES share worthless and a NO share certain to resolve at full value.

Historically, markets with 0% implied probability after a game’s conclusion typically remain static unless an error in result reporting or a cancellation occurs. In this case, the official game summary confirms the Dream won in regular time, with no indication of postponement or cancellation that would trigger a 50–50 resolution [1]. Comparable cases in WNBA prediction markets show that once a final score is confirmed by official sources like the WNBA or ESPN, probabilities lock in unless a formal correction is issued [2].

Traders should monitor official WNBA communications for any post-game rulings, though none are expected given the clear outcome. The key dependency is the finality of the score, which has been verified across multiple sources including the WNBA’s own game summary and ESPN’s live score archive [1][2]. With the settlement window ending 19 July 2026 at 20:00 UTC and the game already concluded, no further catalysts will alter the resolution.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Prediction Market UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Market UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
