Market context
Polymarket is pricing this contract at **1% YES**, which means the market is effectively saying a very low domestic second weekend for *Spider-Man: Brand New Day* is already close to impossible. On Polymarket, that 1% sits inside a USDC-settled position on Polygon, with outcome exposure handled through conditional tokens rather than a direct bet on the film’s business; the only number that matters at resolution is The Numbers’ final domestic 3-day weekend figure for 7–9 August, once it is no longer a studio estimate.
That reading sits against a run of unusually strong opening-weekend comparables. The film reportedly opened at about $360 million domestically, a level that is already record-breaking territory and leaves even a steep second-weekend fall likely to clear many lower brackets. Independent forecasts cited after launch clustered around roughly $142 million to $160 million for the second frame, while some broader models pointed to a final domestic range that still implied a very large hold after opening. The practical lesson for traders is that a 1% price is not about whether the film is popular; it is about whether the second weekend lands in a far smaller tail than the market expects.
The key catalysts are the daily actuals through Friday, Saturday and Sunday, because The Numbers will resolve on the final weekend total rather than estimates. Traders should watch for any shifts in theatre count, premium-format playability such as IMAX, and weekday front-loading that could depress the hold into the lower brackets. If a reputable box-office tracker revises its weekend range sharply before Sunday night, that can move Polymarket pricing even before The Numbers publishes the final domestic figure.
Methodology
This page reviews "Spider-Man: Brand New Day" 2nd Weekend Box Office (Lower Strikes) across five venues. The live probability is the Polymarket mid-price, sourced directly from the on-chain Polygon order book; the comparison columns benchmark each venue on fee structure, KYC, settlement currency and payment rails. Every CTA routes to PolyGram, which mirrors the Polymarket order book at 0% fees.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
FAQ
- 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.
- 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.
- What does Polymarket cost to trade?
- Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.
- 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.
