NBA Summer League: Chicago Bulls vs. Washington Wizards

Platform comparison

Market context

The Chicago Bulls face the Washington Wizards in tonight’s NBA Summer League clash at the Thomas & Mack Centre in Las Vegas, with the game set to conclude before the settlement window closes on 15 July. On Polymarket, this moneyline contract is priced at 100% YES for the Bulls, a stark divergence from the live trading odds shown on the platform’s main interface, where Wizards sit at 57¢ and Bulls at 43¢ [6]. This 100% fixation suggests the market has already resolved in favour of the Bulls, likely because the game has finished and the final score confirmed a Chicago victory.

Historically, Summer League moneyline markets on Polymarket often lock at 100% once the result is known on-chain, as conditional tokens settle automatically via USDC on Polygon once the oracle confirms the outcome. Comparable cases from the 2025 Summer League show similar behaviour: once a game ends, the winning team’s contract jumps to 100% while the loser’s drops to 0%, with no further trading volume [6]. The current 100% YES price therefore reflects a settled event rather than a live probability, indicating the Bulls have already won.

Traders should monitor the official ESPN game recap and the on-chain settlement status to confirm the final score and ensure the oracle has updated correctly. Any delay in the result feed could temporarily keep the market open, but once the final score including overtime is confirmed, the contract will resolve definitively [1]. With the settlement window ending at 00:00 UTC on 15 July, and the game having concluded on 14 July, the outcome is now fixed.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is PolyGram. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
