Bezos Earth Fund's $7.6B Gap Means Triple the Giving Pace

Lauren Sánchez has taken a more public role steering Jeff Bezos's $10 billion climate fund, Fortune reported. The Bezos Earth Fund has deployed $2.4 billion across 335 grants since its 2020 launch. With roughly five years left to give away the remaining $7.6 billion, the annual spending rate needs to more than triple.

Sánchez, the fund's vice chair, announced three major grant batches in late 2025. In September, she committed $37.5 million to protect 835,000 square miles of Pacific Ocean around a dozen island nations. In October, she awarded $30 million to 15 teams using artificial intelligence for conservation and food security. Each team got $2 million. In December, she and her husband committed $102.5 million to homeless services through the separate Day One Families Fund, which has donated more than $850 million to organizations in all 50 states, Washington D.C., Puerto Rico and Guam.

The $10 billion pledge is the largest individual environmental donation on record, Northeastern University said. The pace so far implies annual spending of roughly $480 million. To exhaust the fund by 2030, the fund needs to award about $1.5 billion per year.

Bezos's overall philanthropy remains modest compared with peers. MacKenzie Scott, his ex-wife, has donated $26.4 billion over seven years, 46% of her estimated $35.4 billion net worth, Forbes reported. Bezos has given $4.6 billion, less than 2% of his $266 billion fortune, according to the Bloomberg Billionaires Index. He has not signed the Giving Pledge, a campaign by Warren Buffett, Bill Gates and Melinda French Gates urging billionaires to give away most of their wealth.

Scott has signed the pledge. Asked about the gap, Bezos told CNN in 2022 that efficient philanthropy is difficult. "Building Amazon was not easy. It took a lot of hard work, a bunch of very smart teammates, hard-working teammates, and I'm finding – and I think Lauren is finding the same thing – that charity, philanthropy, is very similar," he said.

The Earth Fund's accelerated spending may increase selling pressure on Bezos's Amazon shares. Bezos funds his philanthropy largely by liquidating stock. He sold roughly $8.5 billion of Amazon shares in 2024 alone, according to SEC filings tracked by Bloomberg. The remaining $7.6 billion in commitments would require additional sales at a rate investors may watch.

The fund's website lists 335 grants totaling $2.4 billion through late 2025. No detailed plan for the remaining $7.6 billion has been made public.
