The biggest IPO ever is here. From Marketplace in New York, I'm Kimberly Adams. SpaceX makes its market

debut today. The company says it has raised the $75 billion it was seeking. It's a record-breaking

initial public offering, valuing SpaceX at $1.77 trillion.

CEO Elon Musk, who will retain voting control, is poised to become the world's first trillionaire.

The stock will debut with a number of unknowns, though, and Marketplace's Nova Saffo is here to

break those down for us.

Good morning, Nova.

Good morning, Kimberly.

Let's start with the biggest unknown. Is the stock

actually worth what the company says it's worth? Yeah, and SpaceX says it's worth $135 per share,

and it confirmed it got that price at public offering. That's how it raised $75 billion. And here's the

issue. The company's sidesteped the typical IPO process, or it makes the case to investors about what its valuation should be.

Instead, SpaceX went directly and just said, take it or leave it, $135. So considering the company is currently losing money, is it really worth more right now than, say, J.P. Morgan Chase, for example.

Well, we're going to find out that in

real time because the company's assertions didn't get tested in the IPO process.

There's also the unknown of how retail investors will affect the stock. Can you explain that?

Yeah, retail investors, meaning individuals can buy the stock before it's public. This typically

is limited to about 10% of shares being issued.

SpaceX, though, set aside a lot more, reportedly 30%.

Here's the thing, though, retail investors can be quick to buy and sell,

so we'll see that get tested in the next few days in the form of whether it's going to cause more volatility than you typically see.

Marketplace is Nova Sopho. Thank you, Nova.
