MacKenzie Scott's net worth was $28.6 billion, according to Forbes' 2026 World's Billionaires List, dated 10 March 2026, where she ranked 84th in the world. The Bloomberg Billionaires Index, in figures cited through 2026, has put her considerably higher, at $39.2 billion, a gap of roughly $10.6 billion, or about 37% of the smaller figure, one of the widest disagreements this series has found. What makes it stranger than most: unlike a private conglomerate with no public price, almost all of Scott's fortune is a single, continuously traded stock, and she has spent the last five years actively giving and selling large chunks of it away.

A roughly $10.6 billion gap between two trackers pricing the same, mostly-public stock is unusual. For comparison, this series found Jeff Bezos's Forbes and Bloomberg figures about 5.9% apart, and Warren Buffett's about 2-3% apart, both fortunes concentrated in one continuously priced company much like Scott's. Neither Forbes nor Bloomberg publishes a full breakdown of what sits behind the difference for Scott specifically.
Scott's fortune traces to a single event: her 2019 divorce from Amazon founder Jeff Bezos, which gave her roughly a 4% stake in Amazon, reported at the time to be worth about $36 billion. Since then she has both donated stock outright and sold shares, and the pace has picked up. Per a regulatory filing reported by Bloomberg on 14 October 2025, Scott held 81.1 million Amazon shares as of 30 September 2025, down 58 million shares, about 42%, from a year earlier, a reduction Bloomberg valued at roughly $12.6 billion at that day's closing price. The filing itself doesn't break out how much of that came from stock sales versus direct donations. Bezos still files the disclosure under his own name and retains voting authority over Scott's shares, a term carried over from the divorce agreement.
AMZN is confirmed on NetWort's screener: /asset/AMZN. For scale, Jeff Bezos's own published profile put his stake at 950 million shares, 8.8% of the company, per Amazon's 2026 proxy statement, more than eleven times Scott's remaining share count.
The giving accelerated too. CNBC, reporting 13 December 2025, said Scott had donated $7.17 billion in 2025 to roughly 225 organizations through her giving platform, Yield Giving, bringing her total given away since 2019 to $26.3 billion across more than 2,700 organizations. CNBC, citing Forbes, said the updated total puts her giving behind only Warren Buffett and Bill Gates among the biggest lifetime philanthropic totals tracked.
The contrast with her ex-husband's own giving is stark and independently sourced on both sides. Fortune, 26 February 2026, reported that Scott's $7.2 billion given in a single year alone exceeded what Jeff Bezos has donated in his lifetime. Separately, Fortune, 15 April 2026, cited a Forbes estimate that Bezos and his wife, Lauren Sánchez Bezos, have given about $4.7 billion total, under 2% of his own net worth, mostly through the Bezos Earth Fund's climate pledge.
Yet Scott's own net worth hasn't fallen in step with any of this. Fortune's 16 July 2026 report, "The MacKenzie Scott paradox," described how a sustained Amazon rally has let her give away and sell tens of billions in stock while her remaining shares simply become worth more, faster than she can distribute them, a dynamic Fortune attributed to Amazon's own share-price gains over the same stretch rather than to anything Scott has done differently.
Structurally, this should be one of the most knowable fortunes in the series, closer to Warren Buffett's fully public, single-company Berkshire stake than to a private conglomerate. Amazon reports its share count every quarter, and Scott's own reductions have shown up in dated regulatory filings, not vague estimates. That makes the roughly 37% gap between Forbes and Bloomberg genuinely puzzling by this series' standards: it's wider than either Buffett's or Bezos's tracker gap, despite Scott's holding being no less transparent than theirs. The likely explanation is not the Amazon stake itself but everything else, the cash and other assets built up from five years of periodic share sales and donations, a moving total that a snapshot estimate has to guess at freshly each time, and one that neither publisher has broken out in public.
Scott has spent five years both selling and donating a concentrated stock position, arguably the most active de-risking effort this series has profiled, and her fortune has still grown in dollar terms because the stock she kept rose faster than she could reduce it. That's the sharpest version yet of a lesson Warren Buffett's profile raised earlier in this series: a strong bull market can outrun even a deliberate, well-publicized effort to shrink a single position. NetWort's portfolio concentration risk piece covers what that kind of exposure actually costs in a portfolio much smaller than a former Amazon shareholder's, and the Explore screener shows how concentrated your own holdings are today.
