• Elon Musk says "money becomes irrelevant" if he's right about what the future holds.
• The Tesla and SpaceX CEO said AI and robots will be better than humans at everything.
• The world's richest man said his fortune could be virtually gone within a few generations.

Elon Musk says money could be meaningless one day, and the vast majority of his wealth will likely be gone within a few generations.

The world's richest person predicted that advances in robotics and space travel will create a multiplanetary economy, at which point "money becomes irrelevant" and "conventional currency will not matter."

Value will be measured in mass and power or energy, he continued. "So that's my guess," he said, adding that it seemed a "pretty obvious" outcome to him.

The Tesla and SpaceX CEO shared his vision of a post-money future and his outlook on his personal fortune with his biographer, Walter Isaacson, on "The Builders" podcast. The interview was taped in early August and released on Tuesday.

Musk recommended earlier this year that people stop saving for retirement in 10 or 20 years, as he expects AI and other technologies to supercharge productivity and usher in an age of abundance where people can have "whatever stuff they want."

He made a similar argument to Isaacson, saying "there won't be anything that humans can do that the AI and the robots can't do better." People will likely turn to hobbies like growing their own fruits and vegetables, or making art, to find purpose in life, he said.

Musk's plans for his own money

Musk, who briefly became a trillionaire after SpaceX went public in June, topped the Bloomberg Billionaire Index at Monday's close with an estimated $920 billion net worth.

He defended his personal wealth on the podcast, saying that it mostly reflects his ownership of SpaceX and Tesla, and he needs large stakes in both companies to retain voting power and remain in charge.

His fortune is "going to be taxed quite heavily," Musk said, adding that there isn't "some magical way to avoid taxes" because "if there were, I would know about it."

Musk said his wealth will "get whittled down and a few generations from now — if money still matters, which I don't think it will — my descendants would have a tiny fraction of what I have."

He also outlined what he hopes his foundation will spend his fortune on after he's gone: "Continue the goals. Make life multi-planetary, extend consciousness to the stars, improve sustainable energy on Earth."

Notably, Musk pledged on Monday to gift a share of SpaceX to every child in the US next year, a contribution worth over $10 billion today.

His announcement has won praise from President Donald Trump, who hailed Musk's "incredible generosity" and labeled him a "legendary friend" in an X post.

Musk teased a charitable pledge in late July after Nobel economist Daron Acemoglu publicly challenged him over his prediction of a post-money future.

"If money won't matter in 2036, why don't you pledge to donate your current wealth of approximately $1 trillion to charity no later than 2036," Acemoglu wrote on X.

"I am actually going to do something along these lines!" Musk responded.

• Elon Musk says he'll give a SpaceX share to every child in the US next year.
• That would be a $10.5 billion gift based on SpaceX's stock price and roughly 72 million recipients.
• Musk said this would be the "first of many" SpaceX share giveaways but didn't offer further details.

Elon Musk says he'll give every child in the US a piece of his space company, a gift worth around $10.5 billion today.

"Next year, I will give one of my SpaceX shares to every kid in America," Musk wrote in an early Monday post on X. "This will be the first of many."

There are roughly 72 million children in the US based on 2025 census data, and SpaceX stock closed at $146 on Friday. If Musk donated 72 million shares right now they would be worth around $10.5 billion.

Musk didn't provide any further details on how the giveaway would work, such as eligibility criteria or specific timing, or whether the shares will be transferred to Trump Accounts.

The Tesla and SpaceX CEO is the world's richest person, with an estimated net worth of $904 billion as of Friday's close, per the Bloomberg Billionaires Index.

SpaceX — the company behind Falcon rockets, Starship launch vehicles, Starlink satellites, the AI chatbot Grok, and X — went public this summer and has a market capitalization of about $2 trillion.

Excluding restricted shares and options, Musk owns 4.77 billion SpaceX shares for about a 36% stake, worth just under $700 billion at Friday's close. The rest of his fortune largely comprises his stakes in his other companies, including Tesla, Neuralink, and The Boring Company.

Donating 72 million shares would reduce Musk's number of SpaceX shares by 1.5%. If, as indicated in his X post, he follows that up with further giveaways, his stake could shrink significantly.

Musk's pledge is part of a broader trend of gifting shares to America's children, aimed at ensuring they all own a piece of the stock market and reap its gains over time, and benefit from a lifetime of compounding wealth.

The Trump administration launched Trump Accounts — tax-advantaged investment accounts — for eligible children this summer, with those born between 2025 and 2028 receiving a $1,000 federal seed deposit. Numerous companies have agreed to contribute to them as well.

Michael and Susan Dell contributed $250 to 25 million American children's Trump Accounts earlier this month, a gift totaling $6.25 billion that was allocated first to those in the lowest-income ZIP codes.

SpaceX President Gwynne Shotwell and her husband pledged in July to give shares of SpaceX to more than 2 million children.

Musk shared his SpaceX gift idea after Anthropic pledged to commit 5% of its shares to a public benefit fund.

"I recommend giving shares directly to the public," he replied on X. "This is what I will be doing."

Another X user described Anthropic and Musk's pledges as "the beginning of universal basic income." Musk corrected him, writing *universal high income."

Musk has predicted that advances in AI, robotics, and other technologies will usher in an age of abundance in which everyone can have "whatever stuff they want."

He's recommended people stop saving for retirement in 10 or 20 years as their nest eggs will be "irrelevant," and has proposed government checks for all as the best response to job losses from AI.

Correction: October 19, 2026 — An earlier version of this story incorrectly described SpaceX as a private company. It went public in June 2026.
