Elba, 41, self-confirmed his appearance at Somerset's Worthy Farm via a Spotify talk at Advertising Week Europe, where he spoke about the "character albums" he focuses on producing.
After completing work as a character in his acting career, he then channels that particular role into music. Following his portrayal of Nelson Mandela, he created Mi Mandela about the late South African politician.
Also performing with Elba in June are Lana Del Rey, Disclosure, Blondie and Warpaint.
Metallica and Prince are joint favourites to headline the Pyramid Stage, despite co-organiser Emily Eavis saying the latter "wasn't booked this year".
