SpaceX Reports $1.293B Bitcoin Position in SEC Filing Ahead of Planned IPO

SpaceX has disclosed in an S-1 registration statement filed with the U.S. Securities and Exchange Commission that it holds $1.293 billion of Bitcoin (BTC) on its balance sheet, marking the company's first public breakdown of its crypto treasury as it prepares for an initial public offering. The filing states SpaceX owns 18,712 BTC, purchased at an average price of about $35,324 per coin, for a total cost basis of roughly $661 million. As of March 31, 2026, the company reported a fair value of $1.293 billion for the position, implying an unrealized gain of nearly 119%. "The company has ownership of and control over its digital assets, which consists of Bitcoin, and utilizes, and expects to continue to utilize thirdparty custodians to hold its Bitcoin," the filing said. Elon Musk has long signaled interest in digital assets through social media, but the S-1 is the first formal acknowledgment that SpaceX holds BTC. Earlier estimates had been largely speculative; analysts monitoring Arkham-linked wallets had pegged the company's holdings at about 8,285 BTC. The disclosure places SpaceX among the largest corporate Bitcoin holders globally and ahead of Tesla. BitcoinTreasuries.net data show SpaceX now ranks seventh worldwide, while Tesla stands 13th with 11,509 BTC. Strategy remains the largest corporate BTC holder, having recently bought 24,869 BTC in a multibillion-dollar purchase, lifting its total to 843,738 BTC. SpaceX said it plans to list on the Nasdaq under the ticker SPCX next month. The company is targeting about $75 billion in proceeds, with an expected valuation of $1.75 trillion to $2 trillion. If completed at that scale, the offering would top Saudi Aramco's 2019 IPO, which raised $29.4 billion and remains the largest on record. In its Wednesday prospectus, SpaceX estimated a total addressable market of roughly $28.5 trillion and said its strategy is to identify opportunities that fit its repeatable business model. The document also indicates Musk will retain about 85.1% of voting power after the listing, preserving significant control over key decisions. The filing comes after last year's high-profile IPO from Circle, the USDC issuer, which raised more than $1 billion and drew heavy institutional demand, with ARK Investment and BlackRock among participants and shares reported to be oversubscribed by more than 25 times.
