Was the pledge to give away most of us while still alive? I know Warren Buffett's original plan was to give away nothing until death and then give away all of it and his wife or something convinced him to at least give away some while still alive. Note that while I think most of the other replies are not necessarily pertinent in that giving away trickles is clearly not "most," the Gates Foundation has given a total of $65.6 billion to date, which is more than half of the Gates family's current net worth, but it isn't funded solely by him. That also means he can't decide unilaterally what to spend the money on, though. I was under the impression it was mostly global health until recently. The education initiatives are relatively new. He could easily still be on track to give away some amount equal to whatever his net worth is on death by his death, though, and still meet a pledge to do it while alive. I don't know that anyone of extremely high net worth has ever tried to give away 50% all at once. I'm not sure that's even feasible in terms of finding organizations that could take and use that much money in a single year, other than donating directly to the US Treasury general fund.
