In 2010, Bill Gates, Melinda French Gates, and Warren Buffett launched a bold initiative: they promised to donate the majority of their wealth to philanthropy. They invited other billionaires to do the same.

The effort, known as The Giving Pledge, quickly attracted 40 of America’s wealthiest individuals and families, including names like Michael Bloomberg and David Rockefeller. Within two months, it seemed to signal a new golden age of giving.

But 15 years later, CNBC reports that the momentum has faded. So what happened?

The rise and stall of The Giving Pledge

At its peak in 2010, The Giving Pledge had 57 signatories, representing 14% of America’s billionaires at the time.

Today, it has 256 signatories globally — including 110 from the U.S. — but that now accounts for just 12% of the U.S. billionaire population, according to the Institute for Policy Studies (IPS).

Enrollment has slowed significantly. Only four new members joined in 2024. Although the number ticked slightly upward in 2025 with 11 new pledgers, it remains far from the initiative’s early momentum.

Meanwhile, billionaire wealth has ballooned. According to Oxfam International, billionaires gained $2 trillion in 2024 alone, bringing their total combined wealth to $15 trillion.

So why are fewer of the world’s wealthiest getting on board?

According to Chuck Collins of the IPS, some billionaires may be overwhelmed by how fast their wealth has accumulated.

“Some of this is fairly sudden, the wealth growth,” Collins told CNBC. “So you got to give people… a decade of slack, if you just land in the billionaire class to figure it out.”

Still, the IPS report criticized The Giving Pledge as “unfulfilled” and “unfulfillable,” with only one living couple — John and Laura Arnold — confirmed to have fulfilled their pledge.

A Giving Pledge spokesperson pushed back, calling the report “misleading” because it ignored donations through private foundations and other channels. They argue the pledge has helped “create new norms of generosity” and foster a global philanthropic community.

A shift in giving or a shift in values?

Younger billionaires aren’t necessarily hoarding wealth — but many are embracing different approaches to giving.

Amir Pasic, dean of Indiana University’s Lilly Family School of Philanthropy, notes that initiatives like Blue Meridian Partners represent a shift toward collective, results-oriented philanthropy.

Others are exploring impact investing or funding tech research. Oracle co-founder Larry Ellison, for instance, launched the Ellison Institute of Technology in 2024 to tackle global challenges — a move consistent with his broader philanthropic interests.

In 2023, venture capitalist Marc Andreessen famously argued that creating world-changing technology is philanthropy in itself — even if the creator pockets billions.

“I think there’s a little more blurring between for profit and nonprofit, charity versus impact investing,” Collins told CNBC.

This evolution reflects broader shifts in how wealth — especially tech-driven wealth — is perceived. Where Buffett and Gates once stood as models of philanthropic responsibility, newer billionaires often see market innovation as their most significant contribution.

While most people will never face the challenge of giving away billions, The Giving Pledge raises important questions about values, legacy, and social responsibility. Whether through time, money, or skills, the lesson remains: giving is about impact.
