Talk of a Tesla-SpaceX merger has resurfaced this week, and with it a fresh round of speculation about how much Bitcoin a combined Musk empire would hold. Elon Musk's two companies have never disclosed a joint crypto treasury, but industry watchers are running the numbers—and the estimates run into the billions.
Where the numbers come from
Tesla's public filings show the carmaker still holds a significant stack of Bitcoin, though the exact size shifts with market moves and occasional sales. SpaceX's holdings have never been confirmed publicly. Musk has hinted in the past that the rocket company owns Bitcoin, but he's never said how much. The speculation now is about what happens if both piles land under one roof.
Why now
The merger idea isn't new. Musk has floated it before, but this week's chatter picked up after a series of cryptic posts on X. No formal proposal has been filed, and neither company's board has commented. Still, the crypto corner of the internet is watching closely. A combined entity would instantly become one of the largest corporate Bitcoin holders on the planet—potentially rivaling MicroStrategy's stash.
What it could mean for the market
If the merger goes through, the new company would have a lot of discretion over that Bitcoin. Musk could sell, hold, or even move it onto a public balance sheet in a way that forces disclosure. For now, it's all speculation. But the rumor alone was enough to get traders talking about a possible overhang—or a bullish vote of confidence, depending on who you ask.
Neither Tesla nor SpaceX responded to requests for comment. The next concrete event to watch is Tesla's annual shareholder meeting next month, where Musk might face questions about the rumor directly.
