Musk Says SpaceX Hits $100 Trillion in 10 Years. That's 48x Today's Value.

Elon Musk says SpaceX will probably be worth $100 trillion within 10 years.

He posted that on X on October 15. His only caveat? A major world war. That's it. No mention of regulators, competition, launch failures, or the fact that Starship hasn't locked in a full orbital refueling cadence yet.

Here's the number that should stop you cold. SpaceX closed October 14 at a $2.07 trillion valuation. Musk's target is roughly 48 times that. For scale, $100 trillion is bigger than the entire S&P 500 right now. Not one company beating the index. One company being worth more than every company in it.

Musk made the call in reply to a clip of Baron Capital founder Ron Baron, who'd forecast up to $50 trillion. So Musk took the over. Late last year he described a $100 trillion SpaceX as merely "possible." Now it's "probably." That's an upgrade, and upgrades from the CEO tend to move secondary market chatter fast.

JUST IN: the guy who runs the company thinks the company is going to be enormous. File that under things we already knew.

But don't dismiss it outright. Starlink is already the cash engine, and it's the part Wall Street actually understands. Falcon 9 hauls more mass to orbit than every other operator on the planet combined. If Starship hits a real reusable cadence, launch stops being a niche service and starts looking like freight.

So can a private company really 48x in a decade? Nvidia did something close to that in about two years. Wild things happen when a business owns the infrastructure everyone else needs.

The market's verdict on Musk's math is still out, mostly because there's no public ticker to argue with. Watch the next Starship flight and any Starlink revenue disclosure. Traders are watching closely. If private secondary marks keep climbing toward that number, the IPO talk gets loud in a hurry.
