Seattle Storm vs. Phoenix Mercury

Market context

Phoenix Mercury host the Seattle Storm in a WNBA regular-season game, and the scoreboard outcome is the only settlement trigger: overtime counts, postponement keeps the market open, and a cancellation would force a 50-50 result. ESPN lists the game as final, with Phoenix winning 93-73, while the pre-game line had Phoenix around -290 on the moneyline and Seattle at roughly +235, showing the market already favoured the Mercury before tip-off.[1]

A 0% YES price is easiest to read as a settlement artefact rather than a live view of game odds. In comparable WNBA match-ups, especially where the scheduled start time has already passed and a result is posted, the implied probability for the losing side collapses to zero because there is no remaining path to that outcome unless the game is voided or replayed. The key comparator is not form alone but whether the event has cleared settlement conditions; once the final score is in, the book depth around deposit and withdrawal flows matters more than pre-match sentiment, because fresh capital from card, bank transfer, SEPA, Klarna, or USDC rails is what keeps markets liquid when early traders have already exited.

For traders watching similar markets, the main catalysts are operational rather than sporting: a late venue change, an official postponement, or an unexpected cancellation would be the only routes back into uncertainty. Ticketing and game listings confirm the fixture was scheduled for 20 June in Phoenix, and ESPN’s live-game page indicates the result is already recorded, so the practical question is whether any league or venue announcement could alter settlement rather than the basketball itself.[1][4]

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
