SpaceX has confidentially filed for what could become the largest IPO in history, targeting a valuation between $1.75 trillion and $2 trillion. If they hit the high end, it would blow past Saudi Arabia's Aramco as the biggest public offering ever. The roadshow is expected in early June, with a listing shortly after.

Let me translate what that valuation actually means: at $2 trillion, you're paying somewhere between 50 to 100 times estimated revenue. For context, that's the kind of multiple that makes Tesla's valuation look conservative. And speaking of Elon Musk, here's the part that should make you nervous—according to the S-1 filing, he retains board control even after the IPO. You're not just buying SpaceX, you're buying whatever Elon decides to do with it.

The bull case is pretty straightforward. Starlink is printing money. The satellite internet business has become massively profitable and generates the majority of SpaceX's cash flow. Throw in the recent merger with xAI—Musk's AI company—and you've got a space-plus-AI story that Wall Street is salivating over. Starship is advancing through testing, and if it works, it changes the economics of getting to orbit entirely.

But here's what worries me. The valuation assumes Starlink continues to dominate, that Starship actually delivers on the Moon and Mars timeline, and that nothing goes sideways with Elon's, shall we say, eclectic management style. We've seen this movie before with Tesla—massive hype, visionary promises, and a stock price that moves more on tweets than fundamentals.

For retail investors, this is going to be tempting. The biggest IPO ever! Space! AI! But remember: IPOs are designed to make early investors rich, not you. By the time shares hit your brokerage account, the easy money has already been made. If you're going to jump in, at least wait to see how it trades in the first few weeks. If they can't explain why it's worth $2 trillion without using the words "revolutionary" or "moonshot," maybe sit this one out.
