Elon Musk’s SpaceX has disclosed a far larger Bitcoin position than outside trackers had estimated, placing the rocket and satellite company among the most significant corporate holders of the cryptocurrency as it prepares for a closely watched market debut.The company’s registration filing with the US Securities and Exchange Commission shows that SpaceX held 18,712 Bitcoin at the end of the first quarter of 2026. The holding had a fair value of about $1.29 billion as of March 31, with market prices lifting its value to roughly $1.45 billion days after the filing became public. The disclosure is materially above earlier wallet-based estimates that placed SpaceX’s Bitcoin exposure at about 8,000 coins.
The filing gives investors a clearer view of a crypto position that had been the subject of speculation since Musk confirmed in 2021 that SpaceX owned Bitcoin. It also shows that the company’s holding is larger than Tesla’s reported Bitcoin balance, underlining how digital assets remain embedded across parts of Musk’s corporate empire despite earlier market volatility and accounting losses.
SpaceX said its Bitcoin was acquired at a total cost of about $661 million, implying an average purchase price of roughly $35,300 per coin. At the values disclosed in the filing, the company was sitting on a substantial paper gain, though the figure remains exposed to sharp price swings. Bitcoin has traded through repeated boom-and-bust cycles since Tesla’s $1.5 billion purchase in 2021 helped accelerate institutional interest in the asset.
The disclosure comes as SpaceX’s planned listing is drawing heavy attention from investors seeking exposure to launch services, satellite broadband, defence-linked space systems and the Starlink network. The company reported 2025 revenue of about $18.7 billion, up from around $14 billion a year earlier, while continuing to fund capital-intensive programmes including Starship, satellite deployment and ground infrastructure.
Bitcoin is not central to SpaceX’s operating story, but it introduces a further variable into an already complex valuation debate. Investors assessing the listing will have to consider not only launch cadence, Starlink subscriber growth, regulatory risk and government contract exposure, but also the way volatile digital assets may affect reported earnings, balance sheet movements and market perception.
The filing states that SpaceX has ownership and control over its digital assets, which consist of Bitcoin, and uses third-party custodians to hold them. That arrangement is common among large institutional holders, but it also places custody, counterparty arrangements and asset security within the risk framework that public investors will scrutinise after listing.
The Bitcoin disclosure also highlights the limits of blockchain-based estimates. Wallet trackers can identify visible holdings linked to known addresses, but they may miss assets held through custodians, newly identified wallets or institutional arrangements that are not publicly tagged. SpaceX’s filing has therefore reset the market’s view of its crypto treasury from an assumed side position to a sizeable balance sheet asset.
Tesla’s history remains the closest comparison. The electric vehicle maker bought Bitcoin in 2021, briefly accepted it for vehicle purchases, then later sold a large portion of its holding. Musk has continued to speak favourably about Bitcoin and Dogecoin, but his companies have taken a more measured public posture toward crypto since the 2022 market downturn exposed the accounting and reputational risks of digital asset holdings.
SpaceX’s position is still far smaller than that of Strategy, the software company that has made Bitcoin accumulation the core of its corporate identity. Yet SpaceX differs because its valuation rests primarily on operational dominance in space launch, satellite internet and future space infrastructure rather than a crypto investment thesis. The Bitcoin balance is therefore likely to be treated as a financial disclosure rather than a strategic pivot.
For the crypto market, the filing carries symbolic weight. A large private technology company moving toward public ownership has confirmed a billion-dollar Bitcoin stake at a time when institutional products, corporate treasury discussions and regulatory scrutiny are reshaping the asset class. The disclosure may strengthen the argument that Bitcoin has moved deeper into mainstream corporate finance, even if most large companies remain cautious about adding it to their books.
For SpaceX, the holding adds both upside and risk. A rising Bitcoin price could lift reported asset values and reinforce perceptions of Musk’s long-running conviction in digital assets. A sharp fall could create earnings noise or revive questions over whether a company with vast capital needs should keep a volatile asset on its balance sheet.
