Seattle Storm vs. Phoenix Mercury

Active sub-markets

Market context

The Seattle Storm are due to play the Phoenix Mercury in a WNBA regular-season game in Phoenix, with the market resolving on the final score after any overtime. At a crowd-implied **0% YES**, the price is effectively treating a Storm win as a near-impossible outcome, but that should be read cautiously: in live sports markets, extreme prices often reflect stale order books, low liquidity, or a fast-moving game state rather than a clean zero-probability assessment.[1][7]

Comparable framing matters because recent meeting data shows the matchup can swing on form and venue. ESPN’s live game page shows Phoenix listed as the home side for this June 20 fixture, while CBS Sports notes the Mercury already beat Seattle earlier in the month, including a June 3 win at Seattle in which Natasha Mack posted a career-high 16 points.[1][7] For a market like this, German GlüStV issues are mainly about access and enforceability rather than game logic: prediction markets offered into Germany can raise gambling-regulation questions under the GlüStV framework, while US-facing exchange activity may also sit within the CFTC’s jurisdiction depending on venue and product structure.[*]

The main catalysts are straightforward: official injury reports, late line-up changes, and any schedule disruption that could trigger a postponement or cancellation. If the game is postponed, the market stays open until completion; if it is cancelled with no make-up, it resolves 50-50, so traders should watch league and team announcements right up to tip-off and through the final buzzer.[1][2][4] On accessibility, “no-KYC up to $1,500” means a user can usually open and trade up to that cumulative amount without completing identity verification, but larger activity or withdrawals may still require KYC checks, which can affect whether a trader can add size to a market like this near settlement.[*]

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

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.
