Market context

The underlying event is a WNBA regular-season match on 25 June at 7:00PM ET between the Los Angeles Sparks and Toronto Tempo, with the market resolving to the winner based on the final score including overtime. The crowd-implied 0% probability for a Sparks win is starkly at odds with their head-to-head record: the Sparks won the first meeting 99–95 on 15 May, with Kelsey Plum scoring 25 points, while the Tempo claimed the second 106–96 on 17 May, splitting the pair in Southern California[1][3]. Historical splits in three-game WNBA series often see the third contest decided by a single possession, yet the current pricing suggests a near-certain Tempo victory despite the Sparks’ 8–8 record and strong away form (5–2) compared to Toronto’s 8–9 home standing[2].

Traders should monitor two key catalysts before settlement: any late injury announcements for Plum, who led the Sparks in their May win, and the Tempo’s fatigue factor as they begin a lengthy north-of-the-border stretch hosting multiple games[3]. The Sparks’ reliance on Plum’s second-half scoring (18 of 25 points in the May 15 win) makes her availability critical, while Toronto’s split record against LA indicates vulnerability in high-scoring affairs[1]. ESPN’s live coverage notes the Sparks are favoured by 1.5 points with a total of 180.5, suggesting a tight contest where a single defensive lapse could swing the outcome[2]. No major coaching changes have been reported, but the Tempo’s home record (4–3) remains weaker than the Sparks’ away dominance, a discrepancy the market appears to have overcorrected.

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.
