SpaceX's official IPO filing with the SEC on Wednesday disclosed a Bitcoin position worth $1.45 billion, comprising 18,712 Bitcoin purchased for $661 million. The holding remains unchanged from the end of 2024, placing SpaceX among the top 10 largest corporate Bitcoin holders. The stash is held with third-party custodians. The filing shows a $112 million unrealized loss in 2025, following a $955 million unrealized gain in 2024. Earlier on-chain movements suggested SpaceX had reduced its holdings, with $143 million in Bitcoin consolidated into a single wallet, leading to estimates of about 8,285 Bitcoin. However, the filing indicates the position was not reduced after 2024, suggesting previous reductions occurred earlier. Tesla, also led by Elon Musk, holds 11,509 Bitcoin. Musk has been a vocal Bitcoin supporter, though Tesla briefly accepted Bitcoin payments in 2021 before reversing due to environmental concerns. He is also known for promoting Dogecoin, which inspired the DOGE government efficiency initiative.
