Market context

The underlying real-world event is a WNBA matchup between the Phoenix Mercury and Indiana Fever scheduled for 22 June at 8:00PM ET, where the market resolves to the winner based on the final score including overtime. Current crowd-implied probability of 0% YES for a Mercury win suggests the market expects an Indiana Fever victory, a stance that aligns with the Mercury’s recent struggles despite their 85–79 win over the Fever in a prior contest that marked their fifth consecutive victory[2]. Historically, comparable cases show that when a team like the Mercury, sitting at 4–12, faces a short-handed but resilient Indiana side (9–7), the underdog often prevails if key absences or coaching adjustments tilt momentum, as seen when the Fever beat the Mercury 107–101 in July 2025 despite being depleted[4].

Traders should watch for announcements on player availability, particularly regarding Caitlin Clark’s status for the Fever and any injury updates for the Mercury’s core, as these dependencies directly influence the outcome[7]. Recent beat-reporter coverage highlights that the Fever’s Aliyah Boston delivered 22 points and 12 rebounds in their July victory, underscoring her pivotal role, while the Mercury’s reliance on Alyssa Thomas—who posted 23 points, 9 rebounds, and 9 assists in their latest win—remains a critical factor to monitor[2][4]. Additionally, the game’s venue at Gainbridge Fieldhouse and the timing near the settlement window ending 23 June 2026 may introduce scheduling pressures that could affect performance, making real-time news from Yahoo Sports or ESPN essential for tracking shifts in probability[5][6].

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.
