Elon Musk says SpaceX could one day be worth vastly more than Earth's economy. Here's what that would take.

Elon Musk has made an astonishing claim that SpaceX could one day be worth orders of magnitude more than the entire global economy. This would put its market capitalization at over $12 quadrillion, or roughly 5,500 times its current valuation of $2.2 trillion. The International Monetary Fund estimates the total value of the global economy at $126 trillion for 2022.

Elon Musk, known for his ambitious predictions, tweeted this bold statement on October 8, 2026. While Musk concedes it's a "super crazy" idea, he believes there's a plausible path to achieving it. Achieving this valuation would require SpaceX's stock price to increase by a factor of 5,500. Even if SpaceX reaches $1 trillion in revenue by 2030 and then grows 100-fold, it would still represent less than 1% of Musk's envisioned valuation.

Experts suggest that significant risks and expenses, such as operating in space or on other planets, could hinder this vision. Critics argue that Musk is using "classic Musk hype and theatre" to attract attention, and investors should treat this statement with caution.
