Elon Musk said on October 8 that he sees a path for SpaceX to be worth several orders of magnitude more than the current terrestrial economy, a claim he himself flagged as sounding completely crazy. Cointribune reported that the phrase implies at least a hundredfold increase and, read literally against an International Monetary Fund estimate of global gross domestic product near $126,300 trillion for 2026, would put SpaceX above $12 million trillion.
Musk then offered a lower benchmark. He said a value above 1,000 trillion dollars now seems to him to be among the set of possible outcomes, where previously he did not think so. He did not present the amount as a target or a prediction, adding that seeing a path is not a statement of extreme confidence in the ability to achieve it. The probability, in his framing, is simply no longer zero.

Key facts
- Musk posted the claim on X on October 8, describing a path to a SpaceX valuation several orders of magnitude above the terrestrial economy.
- The IMF puts 2026 global GDP at about $126,300 trillion, which Cointribune notes would place a literal reading of Musk’s remark beyond $12 million trillion.
- SpaceX is worth roughly $2,200 billion on the market after its June Nasdaq listing, less than 2% of estimated 2026 global GDP.
- Reaching $1,000 quadrillion would require multiplying SpaceX’s capitalization by more than 450, according to Cointribune.
- Cryptobriefing reported that Musk also indicated a 65% likelihood of a Tesla and SpaceX merger before 2028.
Two outlets, two valuations
The reports differ on the current size of the company. Cointribune puts SpaceX at about $2,200 billion following its June Nasdaq listing. Cryptobriefing cites approximately $2.15 trillion after a 2026 IPO and notes the stock trades under the ticker $SPCX. Both figures sit well below the quadrillion-dollar figure Musk floated.
Cointribune points out that comparing a market capitalization with GDP mixes two different measures: capitalization is the value investors assign to all shares at a moment in time, while GDP measures a year of goods and services produced. A company can be worth more than a country’s annual output without holding wealth equal to that economy, and Apple, Microsoft and Nvidia have already passed that mark. No conventional financial model justifies a quadrillion-dollar valuation on SpaceX’s current revenue, profit or activity, Cointribune added.

Orbital data centers and a lunar supply chain
Musk’s scenario rests on more than rocket launches and Starlink subscriptions. It imagines an industrial economy off Earth, with satellites hosting artificial-intelligence chips and data centers drawing solar power in orbit, where panels receive more consistent sunlight and avoid land and grid constraints. Launch costs would have to fall sharply, with Starship becoming rapidly and fully reusable to lift equipment in bulk. Musk then envisions solar panels, radiators and satellites built on the Moon, where lower gravity reduces the energy needed to send hardware into space.
Maintenance of orbital infrastructure, data transmission, component cooling and space debris remain unresolved problems, and Cointribune notes that the lunar industries Musk describes do not yet exist at commercial scale.
Why it matters
The claim arrived alongside a second, more concrete number. Cryptobriefing reported that Musk indicated a 65% likelihood of a Tesla and SpaceX merger before 2028, reviving speculation about how the two companies relate even though no formal merger plans have been confirmed. Cryptobriefing said current market activity appears to reflect increased speculation on that possibility. Musk has previously mentioned synergy between Tesla and SpaceX.
Michael Saylor, executive chairman of Strategy, replied to the post with a single word, replacing the first letter of “bullish” with the bitcoin symbol. Cointribune read the reaction as symbolic rather than an investment announcement, noting that SpaceX itself reported holding 18,712 BTC as of June 30, acquired for $661 million and worth nearly $1.1 billion at that date. Saylor has long argued that growth in the digital economy raises demand for a scarce asset independent of national currencies. Neither outlet reported any new bitcoin purchase by either company.
Nothing in the quadrillion-dollar framing is a forecast, and the valuation gap between Musk’s scenario and the current market price means the discussion remains speculative. This is not financial advice, and crypto and equity markets are volatile and uncertain.
What to watch
Cryptobriefing said official communications from Tesla and SpaceX that confirm or refute the merger speculation will be closely monitored, with formal announcements, SEC filings and statements on earnings calls as the key indicators. Further commentary from Musk or either company’s board could shift how the market prices that likelihood.
