Indiana Fever vs. Phoenix Mercury

Platform comparison

Market context

An upcoming WNBA matchup between the Indiana Fever and Phoenix Mercury, scheduled for 9 July at 10:00PM ET, is the real-world event driving the 66% YES probability favouring the Fever. The market resolves to the winner based on the final score, including overtime, with a 50-50 split if the game is cancelled outright.

Historically, the Fever have held a slight edge in this pairing, winning three of the last five encounters, including a decisive 86-77 victory on 22 June where Caitlin Clark scored 24 points and Kelsey Mitchell added 22[1][5]. That win came despite Clark leaving the previous game on 24 June due to a back injury, a factor that previously saw the Mercury edge them 111-109[7][10]. The 66% implied probability aligns with the Fever’s superior home record (7-3) compared to the Mercury’s away struggles (3-7), echoing their 107-101 win in July 2025 when playing short-handed[1][5].

Traders must monitor Clark’s fitness status ahead of the game, as her availability directly impacts the Fever’s offensive ceiling[7]. The Mercury, led by Kahleah Copper’s 28-point performance in their June 24 win, will seek to exploit any defensive gaps if Clark is limited[7]. With the settlement window ending 10 July at 02:00:00Z, any postponement will keep the market open until completion, making injury updates from the WNBA official site critical before the 10:00PM ET start[7].

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
