Key Highlights
- SpaceX disclosed a massive Bitcoin reserve worth approximately $1.45 billion in its latest IPO filing.
- The company reported holding 18,712 BTC by the end of 2025.
- Elon Musk’s aerospace firm maintained the same Bitcoin position throughout the past year.
Elon Musk’s SpaceX has officially confirmed its significant Bitcoin exposure in a long-awaited SEC IPO filing, revealing that the company currently holds nearly $1.45 billion worth of BTC on its balance sheet.
According to the filing, SpaceX owned 18,712 Bitcoin as of December 31, 2025. The company also stated that it has continued holding Bitcoin since first adding the asset to its corporate treasury back in 2021.
The original acquisition cost for the Bitcoin reserve was reportedly around $661 million. SpaceX further noted that the size of its Bitcoin holdings remained unchanged throughout 2025.
The SEC filing also highlighted the impact of crypto market volatility on the company’s financial statements. SpaceX recorded an unrealized loss of approximately $112 million tied to its Bitcoin investment during periods of price decline. In contrast, the previous year saw strong crypto market gains, allowing the company to report an estimated paper profit of $955 million.
The company stated that its Bitcoin assets are stored with third-party custodians. With nearly 19,000 BTC on its books, SpaceX now ranks among the world’s largest corporate Bitcoin holders.
Reports earlier this year suggested that SpaceX had confidentially submitted IPO paperwork in April 2026. The newly released SEC prospectus now confirms those earlier claims.
SpaceX’s Bitcoin History
Blockchain analytics platform Bitcoin Treasuries had previously estimated that SpaceX once accumulated more than 25,000 BTC during the early stages of the crypto market boom. However, the latest filing indicates the company reduced part of its holdings in prior years.
Last year, blockchain analysts identified wallet activity involving roughly $143 million worth of Bitcoin connected to SpaceX. At the time, many believed the company controlled around 8,285 BTC, though the latest disclosure suggests a much larger reserve than previously known.
Elon Musk has publicly supported Bitcoin on multiple occasions. During a 2021 Clubhouse appearance, Musk described Bitcoin as “a good thing.” Tesla previously accepted Bitcoin as payment before suspending the option over concerns related to the environmental impact of crypto mining.
Despite Musk’s long-standing support for Dogecoin, the latest SpaceX filing made no mention of any DOGE holdings.
