Spidey Tracker, Hulk Theories & Plot Details: The Complete Guide to Spider-Man: Brand New Day

Sony Pictures has turned a plot point from Spider-Man: Brand New Day into a real-world interactive campaign. The Spidey Tracker, launched on June 15, 2026, lets fans track Spider-Man sightings worldwide and unlock exclusive content . The campaign arrives alongside a wave of fan speculation about the Hulk's role in the film, driven by toy leaks, production stills, and a long-standing memory-spell loophole theory. Here's what's confirmed, what's rumored, and what we actually know about the movie's plot and July 31, 2026 release date .

The Spidey Tracker Campaign: Sony's 35-Country ARG

Sony Pictures and Samsung launched the Spidey Tracker on June 15, 2026, as an interactive alternate-reality game (ARG) tied directly to Spider-Man: Brand New Day . It brings a plot point from the film into the real world: in the movie, Ned Leeds (Jacob Batalon) builds a custom website on a Samsung Galaxy device to track Spider-Man's whereabouts — and now fans can use the real version at SpideyTracker.com .

How it works:

• The site features a stylized world map where "sightings" of Spider-Man — both confirmed appearances and rumored ones — light up across the globe as the press tour and promotional events roll out .
• Each pin or stop unlocks exclusive content tied to the film, such as behind-the-scenes clips, trailers, or character teases .
• The tracker is also tied to the film's press tour, letting fans see where cast appearances and premieres are happening in real time .
• It launched across 35 countries and is powered by Samsung Galaxy .

A separate Ned memory twist leak emerged from the campaign's technical code, suggesting Ned may regain memories of Peter Parker through the tracker — though this is an unconfirmed fan interpretation from code-diving, not official canon .

Hulk Fan Speculation: The Evidence (and What's Actually Confirmed)

Mark Ruffalo has been confirmed to return as Bruce Banner in the film . The speculation about his role comes from several converging clues, though none of it has been officially confirmed by Marvel or Sony beyond Ruffalo's casting.

• Memory spell loophole theory: Fans have long argued that Bruce Banner was "present" as the Hulk during the events of Avengers: Infinity War and Endgame, and that the Hulk's unique physiology might make him immune to Doctor Strange's memory wipe from No Way Home, meaning Banner could be the one person who still remembers Peter Parker is Spider-Man .
• Toy leaks: A leaked toy description for Brand New Day appeared to reveal a major storyline involving Banner and potential trouble for both him and Peter Parker . One Hasbro Hulk figure description reportedly references the memory spell loophole directly .
• Production stills: Newly released stills showed Spider-Man working alongside Bruce Banner in a lab setting, with Spidey appearing to repair an inhibitor device Banner uses to suppress the Hulk — implying the Savage Hulk may be on the loose in the film .
• Teaser clip: One teaser showed Spider-Man struggling to hold back a powerful force with his webs, which many fans interpret as the Hulk bursting through .
• Scooper reports: Industry scooper Alex Perez (via The Cosmic Circus) reported that Bruce Banner is "at his wits' end" in the film, setting up both a team-up and a potential clash with Spider-Man, with some suggesting it could lay groundwork for a World War Hulk storyline .
• Fan theory — Hulk & Punisher connection: A prominent theory, outlined by Screen Rant, suggests the Hulk is hunting down criminals connected to a gamma-related underground operation that Frank Castle (The Punisher) is also targeting, creating a three-way collision — all triggered by a lingering symbiote fragment fragment affecting Peter .

None of this is officially confirmed by Marvel or Sony beyond Mark Ruffalo's casting. The exact nature of the Hulk's appearance — whether as Smart Hulk, Savage Hulk, or a different form — remains unconfirmed, though the toy leak and production stills suggest a regression to the Savage Hulk form.

Plot: What We Know From the Official Synopsis

The official synopsis from Sony and Rotten Tomatoes and ELLE describes:

"Fighting crime full-time as Spider-Man in a world that doesn't remember him — and the pressure of seeing his old friends move on without him — sparks a change in Peter he may not be able to come back from."

Key plot points confirmed from various sources:

• Four years after the events of Spider-Man: No Way Home, the world has forgotten Peter Parker exists due to Doctor Strange's memory spell .
• Peter Parker is now an adult living entirely alone, protecting New York City anonymously as a full-time Spider-Man .
• Ned Leeds (Jacob Batalon) creates the Spidey Tracker app in the film to locate Spider-Man so he can thank him for saving his life in high school .
• Peter's superpowers undergo a "surprising and potentially dangerous evolution" .
• A new powerful threat emerges that endangers his friends, forcing him to team up with unexpected allies — including Bruce Banner / Hulk (Mark Ruffalo) and The Punisher (Jon Bernthal) .
• Tom Holland has described the film as a "fresh start" following No Way Home .
