He is the highest !

They should update this list on the main chess.com page:
Even for the bullet expert, thats just incredible. He surely can't really go any higher, and will do well just to sustain the 3100+ ? I don't think its feasible (or possible), to go much higher because theres no one else in that grading region. It would need quite a few 3000+ players up there with him?
