A movement aimed at preserving Jewish philanthropy across generations has crossed a major threshold, with more than 200,000 people now promising to direct a significant share of their future charitable giving toward Jewish causes and the State of Israel.

Jewish Future Promise says its signers represent an estimated $6.821 billion in future philanthropic commitments. Its website currently lists more than 200,100 “Promisers,” marking dramatic growth for an initiative that began with a relatively small circle of major Jewish philanthropists just six years ago.

The promise is deliberately simple. Signers commit that if they leave money to charity after their death, at least 50% of that charitable giving will go toward organizations or causes serving the Jewish people and/or Israel. There is no required donation amount, and the commitment does not mean giving away half of a person’s estate.

Crucially, it is also not legally binding. Jewish Future Promise describes it as a moral commitment rather than a contract, designed as much to spark conversations within families about Jewish identity, values and responsibility as it is to influence where future philanthropic dollars ultimately go.

“Every Promise represents a conversation about the future,” founder Mike Leven said as the organization announced the milestone.

The numbers show how rapidly the idea has expanded. Jewish Future Promise reported 175,186 signers in February, surpassed 184,000 by May and reached more than 195,000 by July before crossing 200,000. In May, the organization said its estimated future commitments already exceeded $6.65 billion.

Leven, a veteran businessman and philanthropist who previously held senior roles at Las Vegas Sands, Holiday Inn and the Georgia Aquarium, launched the initiative with Amy Holtz in 2020. The concept was partly inspired by Bill Gates and Warren Buffett’s Giving Pledge, but adapted around a specifically Jewish concern: ensuring that the enormous transfer of wealth from older generations does not result in Jewish philanthropy disappearing with them.

That concern is becoming increasingly significant. Research firm Cerulli Associates estimates that roughly $124 trillion will change hands in the United States through 2048, including approximately $18 trillion expected to ultimately flow to charities. Much of the wealth currently controlled by Baby Boomers and older Americans will pass to younger generations, potentially reshaping the philanthropic landscape for decades.

Jewish Future Promise argues that the stakes are particularly high for Jewish institutions and Israel as communities confront rising antisemitism, increasing security costs and changing giving priorities among younger donors. The organization is attempting to make support for Jewish causes an explicit part of estate and family conversations before that historic wealth transfer takes place.

Its roster of public supporters includes figures such as Alan Dershowitz, Noa Tishby and prominent Jewish philanthropists, while its broader strategy increasingly focuses on ordinary families rather than only major donors.

The $6.821 billion figure remains an estimate rather than money already donated or legally guaranteed. But with more than 200,000 people now signed on, the movement has grown into a potentially significant effort to influence where billions of dollars in future Jewish philanthropy ultimately go and whether the next generation continues directing substantial resources toward Jewish life and Israel.
