Will Spider-Man: Brand New Day beat Avengers: Endgame's opening weekend record?

Platform comparison

Market context

*Spider-Man: Brand New Day* has opened with unusually strong advance sales, and that is the main catalyst behind the market’s 66% yes price. Variety and CNBC both report domestic opening-weekend tracking in the roughly $260 million to $280 million range, with some analysts even floating $300 million-plus, while Sony’s own stance is much more conservative at about $190 million to $195 million.[1][2][14] That spread matters because the settlement line is $357.1 million, so the film would need an exceptional overperformance, not just a normal superhero hit, to beat *Avengers: Endgame*’s domestic opening record.[1][9]

The historical frame is straightforward: *Endgame*’s $357.1 million debut remains the high-water mark, while *Spider-Man: No Way Home* is the relevant franchise comparator at $260.1 million domestically.[1][9] On pre-release tracking alone, the current market sits above the level implied by Sony’s internal forecast but below the consensus of the most aggressive internet chatter, which is why the price is not closer to certainty despite all the momentum. The pattern suggests traders are leaning on pre-sales and preview strength rather than on a proven path to $357 million, because even the highest credible third-party ranges cited so far fall short of that threshold.[1][3][8]

The next catalyst is the first final The Numbers three-day opening figure for the July 31 to August 2 window, since that is the settlement basis for this market. Until then, traders will be watching whether post-preview grosses and Saturday-to-Sunday holds are strong enough to keep the film inside the upper end of tracking, with CNBC noting robust premium-format sales and analysts still expecting a very large debut.[2] If the final The Numbers total lands near the $260 million to $280 million band, the market should continue to lean yes; if the actuals converge towards Sony’s lower guidance, the probability likely compresses quickly.[1][2]

FAQ

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
