Celebrity bakeoff: Jay Leno, $7,250. Dave Letterman, $7,500. Apple’s Tim Cook, $180,000.

FORTUNE — Talk about two worlds colliding.

On Monday, a Forbes blogger, a Palm Beach hedge fund manager and a paid consultant for IBM, Microsoft and Dell thought Apple’s (AAPL) share price might go up if they spread rumors that CEO Tim Cook was on his way out.

On Wednesday, the Robert F. Kennedy Center for Justice and Human Rights opened bidding on a chance to have coffee with Cook on Apple’s Cupertino campus.

By Thursday morning, Cook had raised more money for the RFK Center than all the other celebrities combined.

Here’s where the bidding stood at 6 a.m:

  • Tim Cook: $180,000
  • David Letterman: $7,500
  • Jay Leno: $7,250
  • Payton Manning: $5,250
  • Francis Ford Coppola: $4,250
  • Robin Williams: $2,500
  • John Mayer: $2,100
  • Tim McGraw: $2,000
  • Alec Baldwin: $2,000
  • David Axelrod: $2,000
  • Alison Sweeney: $2,000
  • Robert DeNiro: $2,000

And so on down the B list.

“Right now, our record for experiences is $255,000 to shadow President Clinton for a day,” says a spokesperson for Charitybuzz, which is running the auction. “We think Cook will break Clinton’s record.”
