With all of King's acting projects, she's amassed a pretty high net worth for a 21-year-old. According to Celebrity Net Worth, King has a fortune of $3 million. That's a lot of zeroes, but it looks like King's net worth is only going to grow. In 2019, she was nominated for an Emmy for her performance as Gypsy Rose Blanchard in the Hulu series The Act. With success comes more high profile projects. King recently signed on to star with Brad Pitt in the upcoming action thriller Bullet Train (via People). 

King could use her significant Instagram following to get serious ad revenue; USA Today reports that people with over a million followers can earn up to $100,000 per promoted post. For now, she seems content to focus on using her social media to promote her acting projects. She's also had a few modeling gigs in her past. In 2019, she was one of the faces for the make-up brand Urban Decay's "Pretty Different" campaign (via Teen Vogue).
