Elon Musk’s recent contemplation of a potential merger involving SpaceX, Tesla, or his artificial intelligence firm, xAI, is drawing attention to a critical yet less-publicized aspect of his business ventures: their substantial corporate bitcoin holdings. Together, SpaceX and Tesla reportedly control nearly 20,000 bitcoin, estimated to be worth approximately $1.7 billion based on current market prices. This positions them as the seventh-largest Bitcoin holder globally, trailing behind CoinDesk-owner Bullish, which holds around 24,300 BTC.
While discussions regarding a merger are in the preliminary stages, and may ultimately not materialize, such a move would centralize these significant bitcoin assets under a single corporate umbrella amidst an environment of fluctuating bitcoin prices and heightened investor scrutiny. SpaceX has been in possession of bitcoin since early 2021 and currently holds about 8,285 BTC, equating to around $680 million. Tesla, on the other hand, maintains a larger stake of 11,509 BTC valued at nearly $1 billion. The electric vehicle manufacturer reported no changes to its bitcoin holdings in the fourth quarter of 2025 but did note a $239 million after-tax loss on its digital assets last quarter, as bitcoin’s value dipped from approximately $114,000 to the low $80,000s.
A potential merger between these companies would not alter the fundamental dynamics of bitcoin itself but would redefine the governance, accounting, and potential financing of this significant corporate asset. Tesla, as a publicly traded company, is obliged to adhere to fair-value accounting rules, which means fluctuations in bitcoin prices directly affect its earnings. Conversely, SpaceX, being a private entity, has been insulated from this kind of quarter-to-quarter financial transparency up to this point.
This distinction is particularly salient as SpaceX is contemplating an initial public offering (IPO), which could value the company at around $1.5 trillion. Institutional investors often conduct thorough due diligence before assessing crypto exposure, even when it is passive, making caution a prevailing sentiment in the context of digital assets on corporate balance sheets.
Tesla’s prior interactions with bitcoin have left a significant mark. The company notably disclosed a $1.5 billion investment in early 2021, sold part of its holdings soon after, and subsequently liquidated approximately 75% of its bitcoin assets in 2022 at bear-market lows. This history has framed Tesla’s reputation as a high-profile yet inconsistent corporate player in the bitcoin arena, making any renewed discussions about Musk-associated bitcoin reserves particularly sensitive.
Despite the ongoing merger talks, neither SpaceX nor Tesla has indicated intentions to buy or sell bitcoin in conjunction with these discussions, and their current holdings constitute a minor part of daily trading volumes. However, the importance of corporate concentration in bitcoin holdings is becoming increasingly relevant, especially amid renewed conversations about the asset’s role on balance sheets, coinciding with gold’s market surge and a broader trend of risk-averse investment strategies.
Regardless of whether SpaceX ultimately merges with Tesla, collaborates with xAI, or opts to remain independent, these discussions underscore how bitcoin has quietly woven itself into the fabric of some of the highest-valued technology companies worldwide. Even when bitcoin does not dominate headlines, it remains a crucial part of the corporate balance sheet—a factor keenly observed by investors.
