Seattle Storm vs. Chicago Sky

Platform comparison

Market context

The Seattle Storm and Chicago Sky face off in a WNBA match scheduled for 12:00 PM ET on 15 July, with the outcome determining the market resolution. In prediction markets, a YES share pays out if the selected event occurs, while a NO share pays out if it does not. Here, the 11% YES probability implies the crowd believes the Storm have a low chance of winning, despite the game being live or imminent as of the settlement window closing at 16:00 UTC.

Historically, teams with poor seasonal records like the Storm’s 6–19 standing often struggle to secure wins against mid-tier opponents, which aligns with the low implied probability. Comparable WNBA games in recent seasons show that teams with similar away records (2–11) frequently lose by margins exceeding the spread, reinforcing the market’s conservative stance on a Storm victory [1][4].

Traders should monitor the final score including any overtime, as the market resolves strictly on the result after all periods. Key catalysts include any official announcements regarding game postponement or cancellation, which would keep the market open or trigger a 50–50 resolution if no make-up occurs [1]. With the game currently open and the spread set at +2.5 for the Storm, the live score and any late injury reports will be the primary drivers of price movement before the 16:00 UTC deadline [1][3].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Market UK, which mirrors the Polymarket order book directly.

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

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

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.
