Market context
The Golden State Valkyries face the Indiana Fever on 22 May at 7:30PM ET in a regular-season WNBA matchup. Polymarket currently prices this contract at 0% for a Valkyries victory, reflecting either extreme confidence in an Indiana win or minimal liquidity in the order book. The conditional token structure on Polygon means traders holding YES tokens receive full value only if Golden State prevails; NO tokens settle to USDC at parity if Indiana wins. Settlement occurs at 23:30 UTC on the scheduled date, allowing roughly four hours post-game for official confirmation.
Historical precedent suggests 0% pricing on WNBA games typically emerges when one team holds a decisive advantage in strength of schedule, injury status, or head-to-head record. The Fever have established themselves as a competitive force in recent seasons, whilst the Valkyries' inaugural roster construction in 2024 positioned them as developmental. Previous expansion-team matchups against established franchises have occasionally resolved at extreme probabilities, though upsets remain possible within a single-game sample.
Traders should monitor official roster announcements through the WNBA's injury report, typically released 24 hours before tip-off. Recent scheduling changes or postponements affecting either team's rest days could shift the underlying matchup dynamics. The Fever's performance trajectory through May will provide real-time context; any significant injuries to key players would represent a material catalyst. Confirmation of the game proceeding as scheduled remains the baseline assumption, with cancellation risk minimal given standard league protocols.
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 PolyGram, 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.
