Spider-Man: Brand New Day Just Set the Biggest Opening Day in History — Here’s the Real Math

Spider-Man: Brand New Day opened on Friday, 31 July 2026, and by lunchtime the film had already rewritten the single biggest day in box office history.

Deadline reported an opening-day figure of $167 million to $173 million including previews. Avengers: Endgame’s first-day record of $157.4 million, set in 2019 and widely assumed to be untouchable, is gone.

But the number is more complicated than the headline suggests — and the far bigger record, Endgame’s $357.1 million opening weekend, has not fallen yet. Here is exactly what happened, what the figure actually includes, and the math that decides the rest of the weekend.

Quick answer: Spider-Man: Brand New Day earned an estimated $167–$173 million on its opening day, 31 July 2026, including a record $72 million in previews. That beats Avengers: Endgame’s $157.4 million first-day record. The three-day domestic estimate is above $330 million, which would be the second-biggest opening weekend ever, behind Endgame’s $357.1 million.

The Numbers So Far

Previews: $72 million. Variety, CNBC and The Hollywood Reporter all reported the same figure, which comfortably beats the $60 million Endgame took in Thursday previews in 2019. It is the largest preview haul any domestic release has ever recorded. Deadline reported that late-evening walk-up business was so heavy that Sony revised its own count upward.

Opening day: $167–$173 million including previews, per Deadline’s Friday estimate. For scale, Spider-Man: No Way Home managed $121.96 million on its first Friday in December 2021, and that film went on to the second-biggest opening weekend of all time.

Three-day projection: north of $330 million domestically from 4,487 North American theatres, according to industry sources cited by Deadline. Forbes, reporting on the same projection, put the estimate at $330 million or more through Sunday.

Theatre count and demand: Deadline noted individual venues running the film 40 to 44 times in a single day in Los Angeles.

Why “Biggest Opening Day Ever” Needs an Asterisk

This is the part almost no coverage is spelling out, and it matters if you want to understand what actually happened.

Opening day now includes previews. The $167–$173 million figure is Friday’s business plus Thursday’s previews plus Wednesday night’s Amazon Prime member early-access screening. That is three separate windows of ticket sales counted as one “day.”

The preview windows are not comparable. Endgame’s preview showtimes started at 6pm on its Thursday in 2019. Brand New Day’s Thursday showtimes began at noon, on top of a Wednesday Prime screening. That is many additional hours of selling time folded into the same record.

Ticket prices are not comparable either. Seven years separate the two films, and premium-format surcharges — 4DX, ScreenX, recliner and large-format pricing — have climbed considerably in that window. Box office records are measured in dollars, not admissions, so newer films carry a structural advantage over older ones.

None of this makes the achievement fake. Brand New Day is genuinely, enormously ahead of pace. But “biggest opening day in history” is a dollar record with a moving definition, and anyone telling you it means more people watched Spider-Man on Friday than watched Endgame on its Friday is guessing.

The Record That Actually Matters: $357.1 Million

Endgame’s opening weekend of $357.1 million domestic — and $1.2 billion worldwide — is the number the industry is watching this weekend.

Here is the math.

Brand New Day needs roughly $185 million across Saturday and Sunday combined to pass it. That sounds achievable after a $170 million Friday. It is harder than it looks, for one reason: front-loading.

When a film sells $80 million in advance tickets and $72 million in previews, it has already served a large share of its most motivated audience before the weekend properly starts. Those fans do not buy a second ticket on Saturday. Paul Dergarabedian of Rentrak flagged exactly this risk in comments to CNBC, noting that huge pre-show numbers can indicate a heavily front-loaded opening driven by opening-weekend urgency.

Endgame had the opposite shape. It converted a smaller preview number into an enormous Saturday, which is what pushed it past $357 million.

So the honest read as of Saturday morning: Brand New Day is close, the projection sits above $330 million, and whether the record falls depends almost entirely on how Saturday holds up rather than on Friday’s headline.

Why Every Prediction Was Wrong

Bolly Flixu covered the forecasts twice before release, and it is worth being straight about how far off the industry was.

Sony’s own projection was a $195 million domestic opening from around 4,300 theatres, in line with third-party tracking, as The Hollywood Reporter reported before release. Tracking firm NRG had the same $195 million low estimate, per Deadline, while rival studios and some analysts argued the real number was closer to $250 million. A handful suggested a start above $300 million was possible. The Washington Times noted a pre-release range of $195 million to $280 million across studio estimates and third-party trackers.

The actual trajectory is above all of it.

Three things tracking underestimated:

1. Advance sales signalled it and nobody adjusted enough. North American presales stood at roughly $80 million, per Deadline — around the level No Way Home posted before its $260 million opening.
2. Reviews landed strong. The film is running around 90–91% with critics; TheWrap reported 91% from critics alongside a 98% audience score.
3. The audience skewed wider than Marvel films usually do. Deadline reported pre-release expectations that women under 25 — typically the last demographic to turn up for a Marvel release — would show up in force, with Zendaya and Stranger Things’ Sadie Sink joining the cast.

The Reception Numbers Are Just as Strong

Box office openings are bought by marketing. Second weekends are earned by word of mouth, and every early indicator here is green.

• CinemaScore: A. Opening-night exit polling.
• PostTrak: five stars from general audiences, from parents, and from children under 12 — reported by Deadline.
• Rotten Tomatoes: around 90–91% from critics, with a 98% audience score, per TheWrap.

The under-12 and parent scores are the ones to watch. A superhero film that plays for families does not collapse in week two, and that is what turns a record opening into a $1 billion run.

The Whole Marketplace Is Setting Records Too

This is the detail that gets lost in single-film coverage. It is not just Spider-Man having a big weekend — the entire North American box office is.

Estimates point to a total domestic weekend somewhere between $407 million and $412 million across all films, which would beat the $402 million the whole market generated during Endgame’s opening weekend in 2019. TheWrap noted that a result on that scale would push the year-to-date domestic total past $6 billion and make $10 billion by year-end look close to certain — a level not reached since before the pandemic.

Format records are falling as well. Reports point to 4DX heading for a record opening weekend of around $4.5 million after all-time high previews, and ScreenX — the format Brand New Day was specifically shot for — tracking toward roughly $4 million.

Internationally, the film posted the biggest superhero opening day China has seen in seven years.

What This Does to The Odyssey

Christopher Nolan’s The Odyssey, which opened 17 July, has been the summer’s story until now — and it is still performing. The film has passed $334 million domestically, making it Nolan’s third-highest domestic grosser, and Showbiz411 reported a worldwide total around $707 million.

Crucially, the two films are not really competing. Brand New Day is drawing a younger, broader, family-inclusive audience; The Odyssey holds the adult IMAX crowd. Their combined pull is a large part of why the overall weekend record

What We Still Don’t Know

Being honest about the gaps is the whole point:

• Saturday’s actual gross. Everything above turns on it.
• Sony’s official weekend figure. Studio estimates arrive Sunday morning; Comscore actuals follow Monday.
• The true worldwide opening. Global figures were projected at $465 million before release and that now looks conservative, but the confirmed number is not in yet.
• Whether it holds. A record opening is not a record run. No Way Home’s $260.1 million debut turned into $1.9 billion globally because it held for months.

Key Takeaways

• Opening day: an estimated $167–$173 million including previews, breaking Endgame’s $157.4 million first-day record.
• Previews alone hit $72 million, the biggest of all time, past Endgame’s $60 million.
• The comparison is not like-for-like — the figure folds in Wednesday Prime screenings and a noon Thursday start, and ticket prices have risen since 2019.
• The three-day estimate is above $330 million, which would be the second-biggest opening weekend ever behind Endgame’s $357.1 million.
• It needs roughly $185 million across Saturday and Sunday to take the all-time weekend record, and front-loading is the main risk.
• Reception is exceptional — an A CinemaScore, five-star PostTrak exits, and a 98% audience score.
• The whole market may set a record, with weekend estimates of $407–$412 million against the $402 million set during Endgame’s debut.
