Market context

The Phoenix Mercury face the Toronto Tempo in a WNBA showdown at 2:00pm ET on 27 June, with the market currently pricing a Mercury win at 42% YES. This contest is the second meeting between the sides this season, following a decisive 98–90 Tempo victory on 19 May where Brittney Sykes and Marina Mabrey combined for 61 points, including Mabrey’s six three-pointers[1][3]. That result saw Toronto cover a +7.5 line as favourites, with the game finishing well over the 169.5 total, suggesting the Tempo’s high-octane offence can overwhelm the Mercury even when playing away[1].

Historical parallels to this 42% probability include matchups where a team lost its first meeting by eight points but entered the rematch with a slight home advantage; in such cases, the home side’s win probability typically hovered between 38–45%, often resolving to the away team if key offensive players remained fully fit[1][4]. The current line implies the Mercury are not expected to replicate their May performance, particularly given Toronto’s 3–2 record and superior away form (2–1) compared to Phoenix’s 2–3 home record[1]. Traders should monitor pre-game announcements on Sykes and Mabrey’s availability, as their absence would significantly shift the probability, alongside any late injury updates from the Mercury’s backcourt[2]. The settlement window closes at 18:00 UTC on 27 June, with the market remaining open if the game is postponed but resolving 50–50 if cancelled entirely[5].

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.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
