Elon Musk said Monday he'd give one of his shares in SpaceX to every "kid" in America next year.

Why it matters: It'd be a roughly $11 billion giveaway at current stock prices, nearly double Michael Dell's record-breaking Trump accounts gift.

What they're saying: " Next year, I will give one of my SpaceX shares to every kid in America. This will be the first of many," Musk said in a post to X just before 4 a.m. ET Monday.

He did not specify if "kid" meant all minors under 18 or some other status, nor did he elaborate on what "first of many" meant.

He also did not reply to X accounts asking if he meant all kids present in the U.S., or just citizens.

By the numbers: Per the Census Bureau, there are just over 72 million people under 18 in the U.S.

If each got one SpaceX share, at Friday's closing price of $146.03, that'd be a market value of a little over $10.5 billion.

Musk owns billions of SpaceX shares, so the giveaway would make only a small dent in his holdings.
