He has gained distinction and acclaim for his blending of various genres including hip hop, pop, R&B, trap, and country.

Malone began his musical career in 2011, and gained recognition with his 2015 debut single "White Iverson", which peaked at number 14 on the U.S. Billboard Hot 100. He signed with Republic Records to release his debut studio album Stoney (2016), which peaked at number four on the Billboard 200 and spawned the diamond-certified single "Congratulations" (featuring Quavo). His second album, Beerbongs & Bentleys (2018) debuted atop the Billboard 200 and set numerous streaming records. It contained the Billboard Hot 100 number-one singles "Rockstar" (featuring 21 Savage) and "Psycho" (featuring Ty Dolla Sign), and was nominated for Album of the Year at the 61st Grammy Awards. His third Billboard Hot 100-number one single, "Sunflower" (with Swae Lee), was released for the accompanying soundtrack to the 2018 animated film Spider-Man: Into the Spider-Verse; it became the highest-certified song in RIAA history as the first to receive double diamond (20-times platinum) certification.

"Sunflower" was also included on Malone's third album, Hollywood's Bleeding (2019), which became his second to peak atop the Billboard 200 and received his second nomination for Album of the Year at the 63rd Grammy Awards. It spawned the single "Circles", which became his fourth number-one song on the Billboard Hot 100, and spent 61 weeks on the chart. His fourth and fifth albums, Twelve Carat Toothache (2022) and Austin (2023), both peaked at number two on the Billboard 200 and saw continued success; the former spawned the top ten singles "I Like You (A Happier Song)" (featuring Doja Cat) and "One Right Now" (with the Weeknd), while the latter explored pop rock and spawned the top 15 single, "Chemical". Two of his 2024 singles debuted atop the Billboard Hot 100: his guest appearance on Taylor Swift's "Fortnight", and his first country pop song, "I Had Some Help" (featuring Morgan Wallen). The latter served as lead single for his sixth album, F-1 Trillion (2024), which further experimented with the genre and became his third non-consecutive number one album on the Billboard 200.

Malone is among the best-selling music artists, with over 80 million records sold. His accolades include eleven Billboard Music Awards, three American Music Awards, six MTV Video Music Awards, and eighteen Grammy Award nominations .
