SpaceX has officially disclosed its Bitcoin holdings for the first time in an S-1 registration statement filed with the U.S. Securities and Exchange Commission (SEC). The aerospace giant, led by Elon Musk, revealed it holds 18,712 BTC, purchased at an average cost of approximately $35,324 per coin for a total investment of $661 million. As of March 31, 2026, the fair value of those holdings stood at $1.293 billion, representing an unrealized gain of nearly 119%. The filing marks the first formal acknowledgment of the company's digital asset treasury and places SpaceX among the world's largest corporate Bitcoin holders, surpassing Tesla’s 11,509 BTC and ranking seventh globally according to BitcoinTreasuries.net.
The disclosure came just days after the Tema Space Innovators ETF (NASA) hit $1 billion in assets under management in a record 37 trading days following its March 31 launch. The fund, now at $1.27 billion AUM, is the only space-themed ETF with exposure to SpaceX via a Special Purpose Vehicle (SPV). Demand for NASA has been turbocharged by excitement around SpaceX’s upcoming IPO, which is expected to raise $75 billion at a valuation between $1.75 trillion and $2 trillion, listing on Nasdaq under ticker SPCX. On a single day, NASA pulled in $375 million in inflows as the SpaceX IPO buzz intensified.
Despite the fund’s popularity, the structure has led to a dilution of SpaceX exposure. Last week, SpaceX made up 10.3% of the ETF; by the filing date, it had fallen to 4.6% as new cash flowed into other publicly traded holdings, because additional private SpaceX shares cannot be simply bought on the open market. Nevertheless, the ETF has gained 46% since inception, outperforming rivals UFO (+32%) and ARKX (+17%).
The SpaceX filing also notes that Musk will retain 85.1% voting control after the IPO. For the crypto market, the revelation of a major institution like SpaceX holding nearly $1.3 billion in Bitcoin is a strong bullish signal, reinforcing the trend of corporate Bitcoin adoption.
