Malone has gained distinction and acclaim for his blending of various genres including hip hop, pop, R&B, and trap. His stage name was derived from inputting his birth name into a rap name generator.

Malone began his musical career in 2011, and gained recognition with his 2015 debut single "White Iverson", which peaked at number 14 on the US 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).

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 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 included on Malone's third album Hollywood's Bleeding (2019), which became his second to peak the Billboard 200. It spawned the single "Circles", which was his fourth number-one song on the Billboard Hot 100 and spent 61 weeks on the chart. It was also nominated for Album of the Year at the 63rd Grammy Awards. His fourth album, Twelve Carat Toothache (2022) was supported by the top-ten singles "I Like You (A Happier Song)" (featuring Doja Cat) and "One Right Now" (with the Weeknd). His fifth album, Austin (2023) explored pop rock and reached similar success, supported by the lead 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).
