Market context
The Indiana Fever face the Portland Fire on 30 May at 8:00 PM ET in a regular-season WNBA matchup. Polymarket currently prices Indiana's victory at zero, reflecting either extreme confidence in Portland or minimal trading volume on this particular contract. The settlement window closes at midnight UTC on 31 May, allowing one full day for the game to conclude before resolution. On-chain, this conditional token pair lives on Polygon, denominated in USDC, with the standard mechanics: a YES resolution to "Indiana Fever" triggers payout of the full notional to Indiana backers, whilst PortlandFire holders receive nothing, and vice versa.
The Fever have finished below .500 in recent seasons but made the playoffs in 2023 after a 13-year drought, whilst Portland has cycled through roster changes and coaching transitions. Direct head-to-head records between these franchises offer limited predictive power given annual roster turnover, though both teams' mid-season form and injury status typically drive market repricing in the days before tip-off. The zero probability on Polymarket likely reflects low liquidity rather than settled conviction; similar low-volume WNBA games often see probability shifts once casual traders or sharp syndicates enter.
Traders should monitor official WNBA injury reports released 24–48 hours before the game, particularly for star players or key rotation pieces. Schedule congestion—whether either team played the previous night—affects rest and fatigue metrics. Recent news from WNBA sources on roster moves or coaching decisions can shift expectations. Postponement risk remains low but non-zero; weather or unforeseen circumstances would keep the market open past the settlement window, triggering a make-up game clause.
Live Data & Statistics
Live stats load when the match begins. Current market odds are shown above. Trading volume: $281K.
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.
FAQ
- Is this market available outside the US?
- Kalshi UK is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.
- 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, Kalshi UK 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.
