Market context
Connecticut Sun played Indiana Fever in a WNBA regular-season game at Gainbridge Fieldhouse, and the listed market can only resolve from the final score once any overtime is accounted for. The fixture has already finished, with 365Scores recording Indiana as the 60-36 winner, which means the contract should be set to **Indiana Fever** rather than remaining open or going to a cancellation fallback.[2]
The current 0% YES price is best read as a stale or fully discounted state rather than a live uncertainty measure. In comparable WNBA head-to-heads, recent form and venue have mattered, but a completed game removes that forward-looking pricing risk; the June meeting between these teams also went Indiana’s way, 85-75, underlining that the Fever have had the stronger recent result in this pairing.[1] For on-chain settlement, the key point is that this market is tied to a discrete sporting outcome, so USDC-denominated positions should move to resolution once the oracle or market operator confirms the final official score.
For traders watching the last mile, the material catalysts are not betting-market chatter but event administration: postponement notices, schedule changes, or an official abandonment decision. If a game is played to completion, the market follows the result; if it is cancelled outright with no make-up, the contract rules say it resolves 50-50. With no evidence of a postponement here, the practical dependency is simply whether the final official score is accepted as the settlement reference.[2]

Methodology
This page reads Connecticut Sun vs. Indiana Fever on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.
Resolution & payout
Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.
Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.
FAQ
- What are crypto prediction markets?
- Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.
- What does a transaction cost on Polygon?
- Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.
- Can I use Bitcoin directly?
- No, Polymarket operates exclusively in USDC on Polygon. You can bridge BTC to USDC via an exchange or bridge service and deposit on Polygon — typically 10-30 minutes processing time.
- How does UMA secure the resolution?
- The UMA Optimistic Oracle uses a bond system: a proposer posts a bond, a two-hour challenge window opens. On dispute the losing side forfeits the bond — financial incentive for honest resolution.
- How volatile are crypto prediction markets?
- Crypto markets react to spot prices — a 5% BTC move typically shifts a "BTC above X by date" market 10-20%. Polymarket crypto market liquidity is usually six-figure USD, sufficient for active trading.
