Market context

The Phoenix Mercury face the Golden State Valkyries on 9 June at 10:00 PM ET in a regular-season WNBA matchup. Settlement occurs at 02:00 UTC on 10 June, with the outcome determined by final score including overtime. The 0% implied probability reflects either minimal trading volume or a technical issue with market initialisation, as both teams carry genuine win probabilities in any competitive fixture.

Historical WNBA matchup data shows that early-season games between established franchises rarely settle at extreme probabilities unless one roster carries documented injury absences or significant roster turnover. The Mercury and Valkyries represent comparable competitive tiers within their conference structures, making a 0% reading unusual without corresponding news of cancellation or force majeure. Previous markets on similar mid-tier WNBA contests have typically opened between 35–65% ranges depending on home-court advantage and recent form.

Traders monitoring this market should track official WNBA injury reports through 8 June, particularly for key rotation players on either side. Weather conditions affecting travel to the venue, if applicable, warrant attention given the settlement window's tight closure. Deposit and withdrawal friction on prediction platforms often correlates with book depth; markets with shallow liquidity at extreme probabilities tend to see rapid repricing once initial capital flows arrive via Klarna, SEPA transfers, or USDC on-ramps. The current 0% reading suggests minimal early backing, meaning the first meaningful deposit cycle could substantially shift the probability curve before tip-off.

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

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.
