"Spider-Man: Brand New Day" 2nd Weekend Box Office (Lower Strikes)

Platform comparison

Market context

Polymarket has this contract at **1% YES**, which implies the market is treating a second-weekend domestic gross in the selected lower-strike band as a very unlikely outcome. For a Polymarket user holding USDC on Polygon, the position only settles into conditional tokens if The Numbers posts a final, non-estimate 3-day total for 7–9 August that lands in the bracket specified by the market rules.

That pricing sits far below the current public box-office conversation. Trade and media forecasts ahead of the second weekend have clustered around roughly **$135 million to $160 million** domestically, with Forbes citing Deadline’s $135 million to $140 million call and Box Office Theory giving a $142 million to $160 million range[3][5]. After a record-setting opening of about **$355 million** domestically, the film has already shown exceptional front-loading, but second-weekend drops on event films can still vary sharply depending on walk-up demand and midweek spillover[7][18].

For a trader, the key catalysts are the final Friday-to-Sunday trajectory, premium-format retention, and whether any late reporting revision shifts the official weekend total used by The Numbers. The market settles only on that site’s final domestic weekend figure, not studio estimates, and the window closes after the 9 August frame is fully finalised[3][6]. With final numbers typically arriving on Monday, the practical watchpoints are Monday trade updates, any revised weekend estimate versus actuals, and whether IMAX and other premium screens continue to cushion the drop into the second frame[3][1].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

UK Frequently Asked Questions

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.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
