OpenAI CEO Sam Altman and his husband have become the youngest billionaires to sign the Giving Pledge, a charity that encourages the ultra-rich to donate their wealth to philanthropic causes.
In their letter, released Tuesday, Altman and husband Oliver Mulherin praised "the hard work, brilliance, generosity and dedication to improving the world of the many people who built the scaffolding of society that allowed us to get here."
"There's nothing we can do but feel immense gratitude and commit to paying it forward, and doing what we can to build the scaffolding a little higher," the pair added.
Bloomberg reports that Altman is worth at least $2 billion, with much of his wealth derived from early stage investments, including a sizeable investment in Reddit. He does not own a stake in OpenAI, the technology company at the forefront of artificial intelligence.
The Giving Pledge was started in 2010 by billionaire Warren Buffett and former married couple Bill and Melinda French Gates to get the world's richest to commit to giving away at least half of their wealth to charities and causes philanthropy, either during their lifetime or in their wills.
This donation is not a legally binding contract, but rather a moral commitment. The aim of the campaign is to "inspire conversation, discussion and action, not only about how much [to give] but also for what purposes and for what results," according to the website. There are currently more than 245 couples and individuals from 30 countries who have signed.
Earlier on Tuesday, Melinda French Gates, who is one of the world's richest and most prominent philanthropists, announced that she would donate $1 billion by 2026 to advance women's rights around the world through the organization her, Pivotal Ventures.
She recently resigned from the Bill & Melinda Gates Foundation earlier this month following her divorce from Bill. As part of her divorce settlement, she received $12.5 billion from the Gates Foundation for her work after her resignation.
