Elon Musk’s SpaceX finally announced a huge amount of Bitcoin in its long-anticipated SEC IPO prospectus. The firm holds nearly $1.45 billion worth of Bitcoin on its balance sheet. Elon Musk’s SpaceX Doubles Down On Bitcoin Holdings As of December 31, the company held 18,712 BTC valued at approximately $1.45 billion, the disclosure revealed. The filing also said Elon Musk’s space firm has retained its Bitcoin holdings since it first recorded the asset in its balance sheet in 2021. The purchase price for the stash was about $661 million. Moreover, the reserve was held constant at the end of 2025, the company said. The SEC disclosure also revealed SpaceX recorded an $112 million unrealized loss stemming from its investments in Bitcoin last year as BTC price dropped. The opposite occurred throughout 2024, when the prices of cryptocurrencies spiked, and the company posted a paper profit of $955 million. Meanwhile, it’s worth noting that the company stores the Bitcoin reserve with outside custodians, according to the filing. The quantity makes SpaceX one of the world’s biggest corporate Bitcoin holders. Previously, SpaceX confidentially filed for an IPO in April 2026, according to reports. Now, with the public SEC filing, the claims can be confirmed. Company’s History With Bitcoin Earlier, Bitcoin tracking platform Bitcoin Treasuries had estimated that SpaceX had purchased over 25,000 BTC in the initial phase of the crypto “bubble.” In the most recent filing, the company appears to have cut off some of that staff in previous years. Last year, blockchain researchers noticed wallet activity for almost $143 million in Bitcoin linked to Elon Musk’s SpaceX. At the time, many thought that the firm held approximately 8,285 BTC. But that new filing suggests that researchers may not have uncovered all of company’s wallets. In the past, Elon Musk has been publicly pro-Bitcoin. He has appeared in the Clubhouse in 2021 and at the time gave it a “good thing” rating. Tesla used to accept Bitcoin payments, but has since changed its stance due to environmental concerns associated with the mining process. Even though Musk has been a long time backer of Dogecoin, the aforementioned filing did not include any mention of the meme coin.
