Elon Musk has floated an extreme long-term valuation for SpaceX.
He posted on X on Oct. 8 that he sees a path to the company being worth orders of magnitude more than the current Earth economy. That is a big claim, even by Musk standards. The comparison is tricky because GDP measures yearly output, while a valuation reflects what investors think a company is worth.
A $1 Quadrillion Outcome?
A day later, Musk gave the idea a number. He said a valuation above $1 quadrillion, or $1,000 trillion, now looks like a possible outcome. He added that he once thought that was not possible. He also said the probability is rising from a very small base. At the same time, he said seeing a path does not mean he is extremely confident. That nuance matters. Global output was estimated at about $126.3 trillion for 2026 by the IMF in April. So Musk is talking about a scale that goes well beyond normal market comparisons.
Solar Power and Reusable Rockets
Musk’s argument rests on moving heavy computing into orbit. In a June 8 discussion filed with the SEC, he described solar-powered AI computing in space. The idea is to put computers on satellites and let them process AI workloads. He listed three needs: launch capacity, solar power, and chips. Lower launch costs would make that easier. SpaceX’s Starship is central to the plan. It needs to reuse both stages with short turnaround times. On Sept. 28, Starship completed its first orbital flight and deployed 26 Starlink satellites, according to the article. Musk also talked about lunar manufacturing, including making solar panels and radiators on the moon. An electromagnetic launcher could then send AI satellites into space. The moon’s lower gravity and lack of atmosphere would help, he argued.
Saylor Replies With Bitcoin Symbol
Michael Saylor, executive chairman of Strategy Inc., responded with one word on Oct. 8: “₿ullish.” The bitcoin symbol replaced the B, tying his reaction to crypto. Saylor has linked SpaceX to corporate bitcoin ownership before. On June 13, he congratulated Musk on SpaceX’s public listing and grouped it with Tesla as major tech firms holding bitcoin. He called the group “Mag8,” adding SpaceX to the Magnificent Seven. SpaceX’s balance sheet also matters here. Its quarterly filing disclosed 18,712 bitcoin as of June 30, unchanged from Dec. 31, 2025. The cost basis was $661 million. The fair value on June 30 was about $1.098 billion. So the valuation talk is not happening in a vacuum. It sits alongside SpaceX’s rocket plans, its AI ambitions, and its bitcoin holdings. Whether any of it reaches Musk’s upper estimate is, of course, far from certain.
