MacKenzie Scott donated over $7 billion in 2025, nearly double the top donor Michael Bloomberg's $4.3 billion, but was excluded from the 2026 Philanthropy 50 list by the Chronicle of Philanthropy. The exclusion stems from the publication's strict criteria, which track funds entering philanthropic vehicles rather than direct donations to nonprofits, and Scott's refusal to provide official receipts. Despite this, Scott remains committed to philanthropy, having donated over 75% of her original Amazon shares through her Giving Pledge.
