Pronóstico: NBA Summer League: Toronto Raptors vs. Boston Celtics

Platform comparison

Market context

The Boston Celtics defeated the Toronto Raptors 83–80 in their NBA Summer League clash on Friday, 10 July, confirming the outcome before the Polymarket settlement window closes. Despite the game being completed, the contract for “Toronto Raptors win” remains priced at 0% YES, reflecting the on-chain reality that the conditional tokens for the Raptors outcome are now worthless on the Polygon network. Traders holding USDC in this market see the resolution locked to Boston, with no path to a 50–50 split cancellation since the match was played and finished in Las Vegas.

Historically, Summer League moneyline markets with 0% implied probability post-game mirror the behaviour of settled conditional tokens where the losing side’s shares are redeemed at zero. Comparable cases from the 2024 and 2025 Las Vegas Summer Leagues show that once a final score is recorded, Polymarket prices collapse to 0% or 100% within minutes, regardless of lingering settlement windows. The current 0% YES price for the Raptors aligns with this pattern, as the 80–83 loss removes any uncertainty about the winner.

Traders should monitor the official Polymarket resolution timestamp and any delay notices from the NBA regarding score verification, though the ESPN and YouTube recaps already confirm the 83–80 result. No further announcements are expected, as the game dependency is satisfied and the conditional token mechanism will automatically settle the market to Boston Celtics. The only remaining variable is the exact UTC time of resolution, which typically occurs within 24 hours of the final whistle.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
