NBA Summer League: Boston Celtics vs. Charlotte Hornets

Platform comparison

Market context

The Boston Celtics defeated the Charlotte Hornets 89–84 in their NBA Summer League clash on 12 July 2026, confirming the 100% YES price on the Polymarket contract for a Celtics win [1]. This on-chain outcome, settled in USDC on Polygon via conditional tokens, leaves no ambiguity: the market resolves to “Boston Celtics” as the final score included no overtime and the game was not postponed or cancelled [1][3].

Historically, Summer League markets with 100% implied probability have resolved cleanly when the game occurs without disruption, mirroring past cases where early-season exhibition wins locked in full settlement without 50–50 splits [1][5]. The Celtics’ 1–0 Summer League record versus Hornets’ 1–1 further supports the certainty of this resolution, as the defending champions entered the contest with sharper form behind players like Liam McNeeley and Hannes Steinbach [2][3].

Traders should monitor official NBA Summer League schedules for any late cancellations, though the Pavilion in Las Vegas hosted the game live on ESPN2 with no indication of postponement [7]. With the settlement window closing on 12 July at 21:00 UTC and the result already confirmed, no further catalysts remain to alter the outcome [1][3].
