Sophie Bathsheba Thatcher was born on October 18, 2000 in Chicago, Illinois. She has an older brother named Alexander, a writer; an older sister named Emma, a filmmaker; and an identical twin sister named Ellie, a visual artist. She started singing at a young age, and wrote her first song later at 14. She has described her family as musical, with her mother being a piano teacher. She herself was classically trained into her teens and started voice lessons at age 9, also at one point singing in a choir. Her parents divorced when she was 14, and she has described her father as "out of the equation."

Thatcher spent her early childhood in Chicago's Hyde Park neighborhood and later grew up in Lake Forest, Illinois. She began acting at age four, entering a performing arts school to pursue musical theater and Broadway. In eighth grade, she moved to Evanston, Illinois where she attended Nichols Middle School, also spending time in homeschooling due to her acting schedule. She later went to Evanston Township High School for one year before completing her high school education in homeschooling. Afterwards, she moved to New York City in order to take Meisner technique classes.

Thatcher began acting professionally at age 11 in a 2012 production of The Secret Garden at Music Theater Works in Chicago. She was later involved in stage productions of Oliver! and Seussical. She also portrayed Anne Frank in a 2015 production of The Diary of Anne Frank. On screen, Thatcher first appeared in the short film Growing Strong (2015). In 2016, she guested on the police procedural series Chicago P.D., an installment in the Chicago franchise. That same year, she and her sister Ellie appeared in a music video for the Lincoln Squares' song "Brighter Days". Later, she made another guest appearance in the horror series The Exorcist (2016), where she played a younger version of Regan MacNeil.

Thatcher made her feature film debut in the science fiction film Prospect (2018), starring alongside Pedro Pascal and Jay Duplass, the latter of whom plays her father. Her performance was praised, with Variety describing her as "a fresh face who tricks us into assuming she's just a callow teen, when in fact, she proves to be the film's toughest character." Later in 2018, Thatcher had a recurring role in the third season of the medical drama series Chicago Med, another entry in the Chicago franchise.

The following year, she appeared in Noble Jones' directorial debut The Tomorrow Man. During this time, Thatcher landed the role of Natalie in Yellowjackets. Regarding the process, creator Bart Nickerson said the casting department was searching for "someone who was really free-spirited and unique who could play both a sort of wildness and a vulnerability." Though most of the auditions were held in-person, Thatcher submitted a self-recorded audition tape and was cast as Natalie before Juliette Lewis, who portrays the character's adult counterpart. The pilot episode was greenlit in September and shot in Los Angeles in November 2019.

In 2020, Thatcher starred in When the Streetlights Go On, a short-form streaming series directed by Rebecca Thomas, which debuted on Quibi on April 6. In November 2020, Thatcher was rumored to be joining the Star Wars franchise but it was unknown in which series she would appear. In December 2020, Showtime gave Yellowjackets a series order; it premiered in November 2021 to rave reviews and became the second-most streamed series in Showtime's history behind Dexter: New Blood.

In early 2022, Thatcher appeared in the Star Wars streaming series The Book of Boba Fett on Disney+. In March, she appeared in the music video for rock band Pavement's 1999 song "Harness Your Hopes." Also that month, she starred in the horror short film Blink, which premiered at SXSW and was made available on YouTube soon thereafter. Later that year, she served as an executive producer on her older sister Emma's film Provo. She next starred in the horror film The Boogeyman (2023), based on Stephen King's short story of the same name.
