Established actress (2024–present)
In 2024, Sweeney had a supporting role in the superhero film Madame Web, set in Sony's Spider-Man Universe franchise. It was released in February and received negative reviews, bombing at the box office. Of the film's commercial and critical failure, Sweeney said, "I was just hired as an actress in it, so I was just along for the ride for whatever was going to happen." In March 2024, Sweeney hosted an episode of Saturday Night Live. After her appearance, the conservative Canadian newspaper National Post ran an article titled "Are Sydney Sweeney's breasts double-D harbingers of the death of woke?" and right-wing political scientist Richard Hanania tweeted "Wokeness is dead" alongside a clip of Sweeney centered on her bust. Sweeney called the obsession with her appearance "this weird relationship that people have with me that I have no control over".
Sweeney then produced and starred in the psychological horror film Immaculate. She originally auditioned for the project in 2014. Years later, she purchased the rights to the screenplay and hired frequent collaborator Michael Mohan to direct. Sweeney has said that she considered producing a way to create opportunities for herself. Later in 2024, she co-starred in Eden, directed by Ron Howard. Reviewing the film for TheWrap, critic Chase Hutchinson wrote that Sweeney "runs away with the whole thing ... it's her subtle looks and a growing agency that turns Eden into something more ... every moment with her at the forefront is Eden at its best."
In June 2025, Sweeney starred alongside Julianne Moore in Echo Valley. She learned how to ride horses for the role. Americana was released in just over 1,000 theaters in August and was labeled a flop by the media, although Deadline predicted it would be profitable for an independent film.
Christy, a biopic about boxer Christy Martin, had its world premiere at the 2025 Toronto International Film Festival. Sweeney starred as Martin and also produced the film. Commenting on the role, Sweeney said she was inspired by Martin's strength and perseverance. She said that playing a character "that has so many layers and depths, that's a dream as an actor ... I'm a very outdoorsy, athletic person, so to play a character that [required me] to transform myself was a dream". Critic Owen Gleiberman wrote that Sweeney gave a "potent, true-note, game-changing knockout of a performance ... She fully expresses the soul of a movie star, which is this: She completely becomes the character, and in doing so becomes us." Though the film was well received critically, it was a box-office disappointment. In the aftermath, Sweeney said: "I am so deeply proud of this movie ... We don't always just make art for numbers, we make it for impact. And Christy has been the most impactful project of my life."
In December 2025, Sweeney co-starred opposite Amanda Seyfried in The Housemaid, an adaptation of the bestselling novel of the same name. The film was successful at the box office, and a sequel is in development with Sweeney set to return in her role. In April 2026, she reprised her role of Cassie in the third season of HBO's psychological drama series Euphoria.
Sweeney will next star in The Custom of the Country, written and directed by Josie Rourke. Sweeney will also star in Gundam, adapted from the Japanese science fiction anime of the same name, alongside Noah Centineo. Sweeney will also reprise her role as Millie in the Paul Feig-helmed sequel The Housemaid's Secret, with Kirsten Dunst co-starring.
Sweeney is also attached to play Kim Novak in Scandalous!, a romantic drama to be directed by Colman Domingo, and Hollow, a reimagining of the 1820 short story The Legend of Sleepy Hollow, directed by Lindsey Anderson Beer.
In June 2026, Sweeney and producer Kaylee McGregor launched Honey Trap, a film and television production company. The company signed a first-look deal with Sony Pictures, under which Sweeney is expected to develop and produce multiple projects.
