Market context
The Seattle Storm travel to Dallas on 1 June for a WNBA regular-season matchup, with Polymarket currently pricing a Storm victory at 6 cents on the dollar. That implies roughly a 6% win probability for Seattle, leaving 94% of conditional token value distributed across Dallas outcomes. The contract settles on Polygon using USDC, with conditional tokens minting at the moment of resolution; traders holding YES positions (Storm) would see their tokens redeemed at parity only if Seattle wins outright.
Historical context matters here. The Storm have finished below .500 in recent seasons and lack the roster depth of Dallas, which has developed into a playoff contender. Last season's head-to-head records and playoff positioning typically anchor opening-week probabilities in WNBA markets. A 6% price for Seattle reflects not merely the gap in current form but also the structural disadvantage of playing on the road in a league where travel fatigue and home-court shooting percentages remain measurable factors. Comparable underdogs in early-season WNBA fixtures have occasionally traded at 8–12% before injury news or lineup confirmations shifted the market.
Traders should monitor official roster announcements through 31 May, particularly injury status for Seattle's key contributors. The WNBA's condensed schedule means last-minute scratches or load management decisions can move conditional token prices sharply in the final hours before tip-off. Dallas's home record and recent form against sub-.500 teams will also influence whether the 6% floor holds or whether late-session trading pushes the probability higher or lower. Game postponement would leave the market open until completion; cancellation without a make-up would trigger a 50-50 split of USDC reserves.

Methodology
This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Kalshi UK, which mirrors the Polymarket order book directly.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
