NBA Summer League: LA Clippers vs. Washington Wizards

Platform comparison

Market context

The underlying event is the NBA Summer League match between the LA Clippers and Washington Wizards in Las Vegas on 15 July, which the Clippers won 100–92 to move to a 2–1 record while the Wizards fell to 1–2[1][2]. For a trader running a polymarket-bot.co.uk script, the 100% YES probability reflects a settled outcome rather than a live forecast, meaning any conditional order tied to pre-game entry would have executed at a stale price before the result was known.

Historically, Summer League markets with 100% implied probability at settlement time almost always correspond to games already completed, as the resolution window closes shortly after the final buzzer; comparable cases from the 2024 and 2025 Summer Leagues show that bots scanning for “arbitrage” on such markets typically return zero profit because the price has already converged to the true outcome[1]. Programmatic approaches should filter out any market where the settlement timestamp precedes the current UTC time, as these are effectively closed loops for automation.

Key catalysts to monitor include the official NBA Summer League schedule updates and any post-game injury reports for rookie players, though these do not alter the resolved outcome[1]. Since the game concluded on 15 July, the only dependency for the bot is confirming the final score via the ESPN live feed to validate the 100% resolution, with no further announcements expected before the 16 July settlement deadline[1][2].

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.
