The numbers come first.
MacKenzie Scott, novelist and ex-wife of Amazon founder Jeff Bezos, has distributed more than $26 billion in charitable giving over a matter of a few years — and has stated she will not stop until 'the safe is empty.' That pace stands in sharp contrast to the broader pattern among America's wealthiest donors.
According to research from the Bridgespan Group, a global consulting firm for nonprofits and philanthropy, families with more than $500 million in assets gave away roughly 1.2% of those assets in 2017. When Bridgespan ran the same calculation for 2023, the figure was essentially unchanged — even as those fortunes had been compounding at rates at or above the S&P 500's long-run average of roughly 9%. In absolute dollars, giving grew. As a share of wealth, it stood still.
Bridgespan cofounder Jeffrey Bradach has labeled this pattern 'slow philanthropy,' arguing in an essay published by the Stanford Social Innovation Review on Thursday that the giving of many ultra-wealthy individuals lags far behind the aspirations they publicly express.
The data on formal giving pledges is no more flattering. The Institute for Policy Studies (IPS) contends the Giving Pledge is 'unfulfilled, unfulfillable, and not our ticket to a fairer, better future.' According to IPS, three-quarters of the original U.S. Giving Pledgers who are still alive remain billionaires today, and just eight of 22 deceased Pledgers fulfilled their pledges.
Melinda French Gates has not been quiet about the gap. 'Have they given enough? No,' she said in an interview with Wired published in late 2025. More recently, French Gates praised Scott's approach, telling Fortune's Most Powerful Women Editor Emma Hinchliffe: 'I look back at the giving MacKenzie [Scott] has done in the last year. Look at what she has said about historically Black colleges in the United States and the importance of them. People are maybe not always speaking about their grant-making, but boy, they are doing it behind the scenes.'
Bradach identifies Scott as the 'most generous individual philanthropist of this century,' pointing specifically to her practice of trust-based, unrestricted giving — releasing funds with minimal oversight and no lengthy application requirements. Noni Ramos, CEO of Housing Trust Silicon Valley, described the model after her organization received a $30 million gift from Scott in late 2024: 'Her style empowers organizations like ours to determine how best to direct funds quickly and innovatively to address pressing issues.'
By contrast, Bradach writes, slow philanthropists fixate on overhead, struggle to delegate, and often underestimate how much capital a nonprofit can actually deploy. 'Every nonprofit seeking support from a philanthropist is not just competing with other nonprofits, but with a donor's option to leave the money in the bank — and maybe give later,' he wrote. 'In the absence of a forcing function, delay is costless to the donor and easy to rationalize.'

CEO Times reads this clearly. Scott's model — high trust, fast deployment, no bureaucratic gatekeeping — mirrors the logic of private capital at its best: get resources to operators who know how to use them, then get out of the way. The slow philanthropy Bradach documents is, at its core, a principal-agent problem dressed in altruistic language. Wealth compounds; the pledge letter collects dust; the nonprofit waits.
Free enterprise rewards decisive allocation. The same principle applies when the asset being deployed is a charitable dollar. The market has already voted on Scott's approach — and the scoreboard reads $26 billion.
