NBA Summer League: Toronto Raptors vs. Boston Celtics

Platform comparison

Market context

The Boston Celtics and Toronto Raptors have already played their NBA Summer League game in Las Vegas on 10 July 2026, with the Celtics winning 83–80 in a tight contest that included every basket from the Raptors’ 83–80 loss [6]. In prediction markets, a YES share pays out if the market’s condition is met (here, that the Toronto Raptors win), while a NO share pays out if it does not; the current 0% YES price implies the market believes a Raptors victory is impossible given the game has finished and the Celtics are confirmed winners.

Historically, Summer League moneyline markets that resolve after a game’s completion settle quickly once the final score is official, and a 0% probability is typical when the outcome is already known—unlike pre-game markets where odds shift with lineups or rest days. In this case, the 50–50 cancellation clause is irrelevant because the game was not cancelled, and the overtime rule did not apply since the result was decided in regulation [6].

Traders should watch the official NBA game summary and any post-game confirmations from ESPN or the NBA’s own site to ensure the settlement reflects the 83–80 Celtics win [1][5]. With the game already completed and the result public, the only catalyst is the platform’s administrative confirmation of the final score, which will trigger immediate resolution to “Boston Celtics” and close the market.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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.

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 Prediction Market UK 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.
