SpaceX founder and CEO Elon Musk said on Monday he'll give every child a share in the company in 2027. 

"This will be the first of many," Musk said in the post on X. 

Musk currently owns approximately 4.8 billion shares in SpaceX, CNBC reported, citing an August SEC filing. 

There are 72 million children under 18 in the U.S., according to U.S. Census data. Handing a share to every one of them would amount to about $10.5 billion worth of shares, based on the stock price at closing on Friday. 

Musk had a net worth estimated at $929.2 billion on Monday, according to Forbes.
