The charity auction site Charity Buzz is hosting a listing for a one-on-one meeting with Cook at Apple's Cupertino headquarters.
At one point Wednesday, the highest bid was at $100,000, more than the amount the experience is valued at, which is $50,000.
The winner and a guest will get to sit down with Cook.
Those interested have until May 14 to bid.
Proceeds will benefit the Robert F. Kennedy Center for Justice and Human Rights.
