Who is Sadie Sink Playing in Spider-man?
Sadie Sink’s exact character in Spider-Man: Brand New Day has not been announced, and she has said she is not allowed to reveal it yet. In recent interviews, including one on The Tonight Show Starring Jimmy Fallon aired in the U.S. on the night of January 6, 2026, she talked about how secretive Marvel is and even described it as “torture” that she cannot say who she is playing.
Reports confirm only a few solid facts so far:
-
She is part of the main cast of Spider-Man: Brand New Day alongside Tom Holland and Zendaya.
-
Her role is important enough that trade outlets expect the character to appear again in Avengers: Secret Wars.
So, the honest answer right now: the character’s name is not official, and any precise label (Jean Grey, Rachel Summers, etc.) is still in rumor territory, not confirmed canon.
Sadie Sink Spider-man Role
Sadie Sink is confirmed to have a key, recurring role in the MCU starting with Spider-Man: Brand New Day, but Marvel is keeping the character “under wraps” for marketing and story reasons.
Entertainment account Culture Crave (@CultureCrave) even noted on X that Sadie Sink actually discovered she had a role in Spider-Man: Brand New Day from the internet, which fits perfectly with how wild and fast the casting rumor cycle moves now.
Industry reports say the part is substantial, not just a cameo, with direct ties to future Avengers movies.
Around the fandom and scoop world, a few ideas keep coming up:
-
Some insiders and commentators keep pushing the idea that she might be Jean Grey, with a version that fits into Marvel’s multiverse and Secret Wars plans.
-
Others say she could be Rachel Summers, a powerful telepathic character from the X-Men side, based on rumor posts and social media “leaks.”
-
Set photo breakdowns have also sparked theories that she could be Rachel Cole, a Punisher-connected character, because of tactical outfits and the grounded tone of Brand New Day.
Right now, these are educated guesses and fan theories, not official confirmations. The only solid, on-the-record information is that she has a major, secret role in Spider-Man: Brand New Day, tied to bigger MCU events.
Latest Updates and Timing
As of today, Wednesday, January 7, 2026 (with U.S. entertainment outlets updating late on January 6, 2026), Sadie Sink is still publicly calling the character a secret. The most recent pieces of news include:
-
A January 5–6, 2026 wave of interviews where she explained she found out about being cast by stumbling across online rumors and then getting it confirmed, which fans loved because it sounded very “modern internet.”
-
Coverage from major entertainment sites noting again that Marvel has not let her say the character’s name, even while promoting Spider-Man: Brand New Day.
Spider-Man: Brand New Day itself is scheduled to release in theaters on July 31, 2026, positioned as the start of a new Spider-Man trilogy and a late chapter in the Multiverse Saga.
Filming and set-spotting through 2025 showed Sadie Sink on set in long coats and low-key outfits, which only fueled more speculation about whether she is playing a street-level ally, a mutant, or someone linked to the Punisher or X-Men.Rumors vs confirmed facts (quick view)

Why Fans Are So Focused on This Role
Fans are paying close attention because Sadie Sink already has a strong reputation for playing intense, emotionally grounded characters in projects like Stranger Things.
A grounded Spider-Man movie that still connects to multiverse stories makes her casting feel like a bridge between street-level drama and big, cosmic stakes, which is why theories swing back and forth between “street vigilante” guesses and “mutant powerhouse” guesses.
For viewers searching “who is Sadie Sink playing in Spider-Man,” the most useful, accurate answer right now is: the studio has confirmed the casting, the film, and the importance of her role, but not the character’s name, and any specific label is still speculative until Marvel or Sony officially speak.
