It comes after the organiser said he wanted to book acts to appeal to younger people.
Eavis told BBC Somerset he wanted to "break with tradition this time and put on something totally different".
He said of Jay-Z: "He will appeal to the young people and under-25s for sure, so that's a big pull for them.
"It's not like the traditional one we do, like Radiohead, Coldplay and Muse and Oasis."
The news makes it unlikely Kanye West will perform, as had been rumoured.
Registration for the festival has now started and those who want to attend must register their details by March 15. Tickets will go on sale on April 6.
