Of the wealthiest people in the world, about 250 have pledged to give away the majority of their fortune—an effort coined the Giving Pledge. It was started by Bill Gates, Melinda French Gates, and Warren Buffett in 2010, and billionaires including Mark Zuckerberg, Elon Musk, Larry Ellison, and Bill Ackman have signed on.
Although it’s often also referred to as the Billionaire’s Pledge, other wealthy donors have committed to the endeavor. One of the latest signatories is Craigslist founder Craig Newmark, who announced on LinkedIn this weekend he’s officially joining the Giving Pledge.
“Okay, I’ve formally signed up for the Giving Pledge, sometimes considered the Billionaire’s Pledge, though I’ve never been a billionaire, particularly after I gave away all my Craigslist equity to my charitable foundation,” Newmark wrote. “Seems like a good way to officially enter my middle seventies, which I’ve done today.”
Newark built his fortune by founding popular online marketplace Craiglist in 1995. It started as an email list for local San Francisco residents but turned into an online classifieds page the following year. Today, Craigslist is estimated to be worth about $3 billion.
“This all feels like a follow-up to my decision in early 1999 to monetize Craigslist as little as possible,” Newmark said of signing the Giving Pledge. “The best estimate so far is that I turned down around $11B that bankers and VCs wanted to throw at me. I still made plenty after that.”
In 2020, Forbes estimated Newmark’s net worth at $1.3 billion, although in 2022 he said he’d give away most of his fortune to charitable causes. There aren’t more recent estimates of his net worth, but he emphasized in his LinkedIn post he is not a billionaire.
His foundation, Craig Newmark Philanthropies, mostly supports cybersecurity and veterans causes. And in his post committing to the Giving Pledge, Newmark said he’d continue making similar donations.
“My focus is where I can do some actual good in neglected areas, like for military families and vets, like fighting cyberattacks and preventing scams,” he wrote. “Also, a little for pigeon rescue.”
Wait, what?
Newmark is also dedicated to rescuing pigeons.
“I love birds, have a sense of humor, and I suspect that pigeons may become our replacement species,” he told the Associated Press in 2023.
His favorite neighborhood pigeon is named Ghostface Killah, who is featured in a painting on Newmark’s mantle at home.
He said he developed his love for pigeons in the mid-1980s when he lived in Detroit. Pigeons are “the underdog,” he told NYU’s student newspaper Washington Square News.
“They’re the grassroots, most prominent bird and possibly our successor species,” Newmark said. “But pigeons are, well, I identify with them as well. I grew up with no money, living across the street from a junkyard.”
Early this year, Newmark donated $30,000 to San Francisco–based pigeon rescue Palomacy, which was the largest donation the organization had ever received.
“Craig Newmark is many things: the founder of craigslist, an ‘accidental entrepreneur,’ a self-proclaimed old-school nerd, a full-time philanthropist, and a lifelong lover of pigeons,” Palomacy said in January. “We so appreciate the support they provide our feathered friends.”
With Newmark’s donation, Palomacy can continue to “save hundreds of pigeons and doves through hands-on rescue, rehabilitation, and rehoming in Northern California,” according to the organization. “We are reversing the unfair stigma against pigeons and showing the world they deserve our respect and protection.”
Recent criticisms of the Giving Pledge
Although there undoubtedly are some billionaires and other high-net-worth individuals who are genuinely committed to the Giving Pledge, there has been recent criticism many of the signatories aren’t living up to the pledge. Even Melinda French Gates, one of its founders, recently said people could be doing more.
“Have they given enough? No,” she said in a recent interview with Wired.
Treasury Secretary Scott Bessent last week also called the Giving Pledge a failure—but for different reasons. He said it was “well intentioned,” but was “very amorphous” and claimed wealthy people made the commitment out of fear that the public would “come at it with pitchforks.” Bessent also pointed out that not many billionaires have actually delivered on their promise to donate their fortunes.
Warren Buffett, another Giving Pledge founder, also recently admitted he had to rethink some of his original philanthropic plans.
“Early on, I contemplated various grand philanthropic plans. Though I was stubborn, these did not prove feasible,” he wrote in a recent letter to shareholders. “During my many years, I’ve also watched ill-conceived wealth transfers by political hacks, dynastic choices, and, yes, inept or quirky philanthropists.”
Several studies have also poked holes in the Giving Pledge, showing how it has benefitted billionaires by presenting themselves as generous and public‑spirited, but doesn’t question inequalities and tax rules that led to such massive wealth in the first place.
The Institute for Policy Studies (IPS) argues the Giving Pledge is “unfulfilled, unfulfillable, and not our ticket to a fairer, better future.”
To be sure, many wealthy signatories like Newmark appear to be genuinely committed to the cause.
“Like I say, a nerd’s gotta do what a nerd’s gotta do, and a nerd should practice what he preaches,” Newmark wrote over the weekend.
