Predicting 100 years ahead is extremely difficult. Just look at authors from 100 years ago.
Toni Morrison is close to a safe bet but sadly doesn’t meet your criteria any longer.
So Pynchon seems like the clear winner. He’s the James Joyce of postmodernism so I’d be very surprised if he isn’t read in 100 years. If you want more accessible literature there is Franzen and Chabon.
