In a post early Monday, Musk wrote: "Next year, I will give one of my SpaceX shares to every kid in America. This will be the first of many."
According to US Census Bureau data, there are just over 72 million people under 18 in the country. SpaceX shares closed at $146.03 on Friday, meaning the donation would be worth approximately $10.5 billion. Axios put the value at around $11 billion based on the same figures.
Musk owns billions of SpaceX shares. Multiple sources put his stake at more than 4.8 billion shares, representing about a 10.5% to 36% ownership depending on the class of shares, with the higher figure including unvested awards and options.
The announcement came hours after rival artificial intelligence company Anthropic said it would commit 5% of its shares to a new public benefit fund. Musk replied to Anthropic's post on X: "I recommend giving the shares directly to the public." He later added: "This is what I will be doing."
Musk's pledge follows a pattern of wealthy donors contributing stock to Trump Accounts, tax-advantaged investment accounts for children launched by the Trump administration this year. SpaceX president Gwynne Shotwell pledged shares to 2 million Trump Accounts in July, and Michael Dell contributed $6.25 billion to the accounts earlier this month.
The timing and mechanics of the share transfer remain unclear. Musk did not say whether the shares would be placed in Trump Accounts or distributed by another method, nor whether 'every kid' includes only citizens or all children present in the US.
Musk has previously argued that advances in AI and robotics will create an age of abundance, and has suggested that direct share ownership could function as a form of universal high income.
SpaceX went public in June 2026 and has a market capitalisation around $2 trillion. The company's rocket business remains relatively small compared with its valuation, which investors have tied largely to its AI ambitions through subsidiary xAI.
