Elon Musk’s recent considerations of potential mergers involving SpaceX, Tesla, or his artificial intelligence firm, xAI, have sparked renewed focus on a lesser-known aspect of his business empire: substantial corporate Bitcoin holdings. Collectively, SpaceX and Tesla hold nearly 20,000 Bitcoin, currently valued at approximately $1.7 billion. This positions the joint entities as the seventh-largest holder of Bitcoin globally, trailing only behind Bullish, the owner of CoinDesk, which possesses about 24,300 Bitcoin.
While discussions around a potential merger are still in the preliminary stages and could ultimately fall apart, such a combination would centralize Bitcoin assets under a unified corporate structure, particularly significant at a time when Bitcoin prices are experiencing volatility and heightened investor scrutiny.
Since early 2021, SpaceX has amassed a Bitcoin reserve of about 8,285 BTC, worth around $680 million. Tesla, on the other hand, holds approximately 11,509 BTC valued close to $1 billion, and there have been no reported changes to this position in the fourth quarter of 2025. However, Tesla’s involvement in Bitcoin has had its challenges; the company recently reported a $239 million after-tax loss on its digital asset holdings as prices fell from approximately $114,000 to the high $80,000 range.
A merger would not alter Bitcoin’s fundamental characteristics; however, it could significantly impact how one of the largest corporate Bitcoin holdings is managed, accounted for, and potentially accessed for financing. Tesla, being a public company, adheres to fair-value accounting standards, meaning fluctuations in Bitcoin prices directly affect its earnings reports. SpaceX, remaining private, has thus far been insulated from this kind of financial visibility.
This distinction is crucial as SpaceX contemplates an initial public offering (IPO) that could value the company at around $1.5 trillion. Institutional investors, many of whom approach digital assets with caution, may factor in crypto exposure during their due diligence process.
Tesla’s historical interactions with Bitcoin remain a key point of consideration. In early 2021, the company disclosed a $1.5 billion investment in Bitcoin, subsequently selling a portion shortly thereafter and liquidating roughly 75% of its holdings in 2022 during a bear market. This series of events has cast Tesla as an inconsistent corporate holder of Bitcoin, amplifying scrutiny on any renewed focus involving Musk’s connections to Bitcoin reserves.
As discussions unfold, neither SpaceX nor Tesla has indicated intentions to alter their Bitcoin positions as part of the merger talks. The companies’ combined holdings constitute a minor portion of daily Bitcoin trading volumes. Nonetheless, the concentration of these corporate assets may influence market perceptions, especially given the ongoing debate regarding Bitcoin’s role as a balance-sheet asset amid the surge of gold and broader risk-off financial trends.
Regardless of whether SpaceX aligns with Tesla, partners with xAI, or maintains its independence, the discussions illuminate the quiet yet significant role Bitcoin has come to play in some of the world’s leading technology firms. Even when it isn’t the main topic of conversation, Bitcoin remains embedded within the balance sheets of these corporate giants, continuously drawing the attention of investors.
