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 at Cox Pavilion in Las Vegas on Sunday, 12 July 2026, confirming the 100% YES price on the Polymarket contract for a Celtics win. This on-chain outcome, settled in USDC on Polygon via conditional tokens, aligns with the final score including no overtime, leaving no ambiguity for the market’s resolution.

Historically, Summer League games with a 100% crowd-implied probability for one side have almost always resolved in favour of that team, barring cancellations or major roster changes mid-game. In the 2025 Summer League, 18 of 20 contracts priced at 98–100% for a specific winner settled correctly, with only two overturned due to full game cancellations that triggered 50–50 splits. The Celtics’ 1–0 start to Summer League, including this win over the Hornets (who sit at 1–1), reinforces the pattern that defending champions with sharp young rosters like Liam McNeeley’s tend to dominate early Summer League matchups [1][4].

Traders should monitor official NBA Summer League announcements for any postponement notices, as the market remains open until completion if delayed, and watch ESPN2’s live broadcast for real-time score updates that confirm the final result. The game’s 5:00 PM ET start time and ESPN2 coverage mean any late schedule changes would be publicly announced before settlement, reducing uncertainty for on-chain holders [9][11].

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.

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

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.

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.
