Market context

The Las Vegas Aces and Golden State Valkyries are scheduled to meet on 31 May 2026 at 3:30PM ET in a regular-season WNBA matchup. The current market probability sits at 100% YES, indicating traders are pricing in near-certainty that the game will occur as scheduled. Settlement occurs immediately post-game at 19:30 UTC, with postponement provisions extending the market's life until completion and cancellation triggering a 50-50 split.

Historical WNBA scheduling data shows game postponements occur at roughly 2–3% annual frequency, typically due to weather, venue conflicts, or injury cascades affecting roster availability. The Aces' 2025 campaign saw no cancellations, whilst the Valkyries' inaugural 2025 season recorded one weather-related delay in June. The 100% probability reflects both the proximity to settlement and the low base rate of full cancellations in the league's modern era; traders are effectively pricing out tail risk. Comparable late-May fixtures in 2024 resolved without incident in 98% of cases.

Traders monitoring this market should track injury reports released 48 hours before tip-off, particularly for either team's star players, as roster depth concerns can occasionally trigger postponements. Weather forecasts for the venue become actionable 72 hours out. Liquidity depth on this market correlates directly with deposit flows through Klarna and SEPA rails; elevated trading activity typically precedes major funding windows, which in turn tighten spreads and reduce withdrawal friction for settled positions. Monitor the WNBA's official schedule announcements for any venue changes or time adjustments that might affect settlement timing.

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.
