NBA Summer League: Golden State Warriors vs. Memphis Grizzlies

Platform comparison

Market context

The Golden State Warriors and Memphis Grizzlies faced off in the 2026 NBA Summer League at Cox Pavilion in Las Vegas on 14 July, with the game already completed under the 5:00 PM PDT slot. On Polymarket, this USDC contract on the Polygon chain currently prices the Warriors’ win at 0% YES, implying the market has already resolved to Memphis Grizzlies based on the final score including any overtime. The conditional tokens reflect a settled outcome rather than an open probability, as the settlement window closes at 23:00 UTC on 14 July, matching the game’s actual completion time.

In past Summer League markets, 0% probabilities typically appear only after a result is confirmed on-chain, not as a pre-game forecast. Comparable cases from the 2024 and 2025 Las Vegas tournaments show that when a team loses outright, the opposing share collapses to zero once the official score is posted, with no further volatility. This mirrors the current pricing, where the Grizzlies’ victory has locked the contract, leaving no room for the Warriors to win.

Traders should monitor the official NBA scorebook and any on-chain resolution announcements on Polygon to confirm the final tally. While the game has passed, late adjustments to the official result—such as scoring corrections or forfeit rulings—could theoretically reopen the market, though such events are rare in Summer League. No recent news sources indicate a postponement or cancellation, and the 2026 schedule confirms the match took place as planned [1][2].
