SpaceX's $75 Billion IPO Will Be the Biggest in History — But Here's Why It's Not Really About Rockets Anymore

I've been watching SpaceX since the early Falcon 9 days, and I never thought I'd be writing about them the same way I write about cloud computing companies. But here we are. SpaceX just announced plans to raise $75 billion in its IPO — the biggest in the history of the stock market — and when you read the fine print, it's clear this company has transformed into something much bigger than a rocket company.

The Numbers First: This Is Historic

Let's set the stage. SpaceX plans to sell 555.6 million shares at $135 per share, valuing the company at approximately $1.77 trillion. For context, the previous record for the biggest IPO ever was Saudi Aramco's $29.4 billion raise in 2019. SpaceX is targeting more than double that amount. It's not just a new record — it's a different category entirely.

Trading is set to start next Friday. If you've been waiting for this, the wait is almost over.

It's an AI Company Now (Sort Of)

Here's where it gets interesting. The IPO documents don't just talk about rockets and Starlink satellites. They explicitly emphasize SpaceX's plans for artificial intelligence and putting data centers in space. Yes, you read that right. Space-based AI data centers.

The logic makes a strange kind of sense when you think about it. Earth-based data centers have massive constraints: land costs, cooling requirements, power infrastructure, regulatory hurdles. A data center in low Earth orbit has none of those problems. SpaceX already has the launch capability, the orbital infrastructure from Starlink, and the manufacturing scale to make this viable in a way no other company can match.

The company plans to use IPO proceeds to "feed the massive capital expenditure needs of both its space and AI businesses." That's direct language from the filing. SpaceX isn't being coy about where this is going.

Musk's Control — And His Staggering Net Worth

After the IPO, Elon Musk will control 82.4% of the voting power. That's an extraordinary level of control for a public company of this size, but given how SpaceX has performed under his leadership, it's hard to argue with the track record.

On a personal finance note that's almost surreal to type: Musk's stake in SpaceX at the IPO price would be worth $841 billion. Add his Tesla stake of roughly $300 billion, and his net worth could approach $1.1 trillion. That would make him the first person in history with a 13-figure net worth. Say what you want about Musk — and people say a lot — but that number is genuinely unprecedented in human history.

What This Means for the Broader Tech Ecosystem

A $75 billion IPO doesn't happen in a vacuum. This is going to move markets, suck oxygen from other tech IPOs, and potentially accelerate investment in the whole space-plus-AI infrastructure thesis. We already saw Alphabet announce an $80 billion stock sale explicitly earmarked for AI compute. Microsoft is pushing into on-device AI agents. And now SpaceX is positioning itself as a space-based AI infrastructure play.

The pattern is clear: the biggest companies in tech are all making massive bets on AI infrastructure. The question is who builds the picks and shovels for the AI economy — and SpaceX just made its bid to be one of them, from orbit.

Should You Buy?

I'm not a financial advisor, and this isn't financial advice. But I'll say this: the SpaceX story is unlike anything we've seen in public markets. The combination of launch dominance, Starlink's growing revenue base, and this emerging AI infrastructure angle creates a genuinely unique investment thesis. The $1.77 trillion valuation is steep — but so was Amazon at every stage of its growth, and so was Tesla.

If the space-based AI data center vision works even halfway, the current valuation might look cheap in five years. If it doesn't, you're still owning the world's most capable launch company and a satellite internet business growing faster than almost anything else in tech.

Next Friday is going to be a very interesting day in the markets.
