Giving USA 2026 reports 2025 philanthropy at a record $617 billion, up 3% in inflation-adjusted terms. Bequests and megagifts from a handful of ultra-wealthy donors drive the rise, with MacKenzie Scott contributing about a third of megagift dollars and Warren Buffett, Bill Gates and Michael Bloomberg among top benefactors. The stock market boom underpins broader giving across individuals, foundations, and corporations.
