SpaceX has formally disclosed that it holds 18,712 Bitcoin on its balance sheet, valued at approximately $1.293 billion as of March 31, 2026, according to an S-1 registration statement filed with the U.S. Securities and Exchange Commission. The filing, submitted ahead of the company’s planned initial public offering, marks the first time the aerospace firm has publicly confirmed the size of its cryptocurrency reserves.

First Official Disclosure of SpaceX Bitcoin Holdings

The SEC filing reveals that SpaceX acquired its 18,712 BTC at an average cost of approximately $35,324 per coin, representing a total investment of roughly $661 million. Based on the March 31 fair value assessment of $1.293 billion, the position reflects an unrealized gain of approximately 96 percent. The filing states that SpaceX “has ownership of and control over its digital assets, which consists of Bitcoin,” and that it “utilizes, and expects to continue to utilize third-party custodians to hold its Bitcoin.”

The disclosure resolves years of speculation about the company’s digital asset exposure. Prior to the filing, on-chain analytics firm Arkham Intelligence had estimated SpaceX’s holdings at approximately 8,285 BTC, a figure that proved to be significantly below the actual amount. The confirmed holdings place SpaceX among the largest corporate Bitcoin holders globally, ranking approximately seventh according to data from BitcoinTreasuries.net, and surpassing Tesla, which holds 11,509 BTC.

SpaceX IPO and Corporate Strategy

SpaceX plans to list on the Nasdaq under the ticker SPCX, with the company reportedly targeting a raise of approximately $75 billion at a valuation between $1.75 trillion and $2 trillion. If achieved, the offering would surpass Saudi Aramco’s 2019 IPO, which raised $29.4 billion and remains the largest public debut on record. The prospectus indicates that CEO Elon Musk would retain approximately 85.1 percent of voting power following the listing, maintaining substantial control over corporate decisions.

The filing describes a total addressable market of approximately $28.5 trillion, encompassing the company’s satellite internet, launch services, and space exploration operations. The Bitcoin disclosure adds another dimension to the company’s financial profile ahead of what would be a landmark public offering in both the aerospace and financial markets.

Broader Corporate Bitcoin Adoption Context

SpaceX’s disclosure arrives amid a broader trend of corporate Bitcoin treasury adoption. Strategy, formerly MicroStrategy, remains the largest corporate holder with 843,738 BTC following a recent purchase of 24,869 coins. The growing list of public and soon-to-be-public companies holding Bitcoin on their balance sheets reflects an evolving corporate treasury landscape where digital assets are increasingly treated as reserve instruments.

The timing of the disclosure is also notable given the current regulatory environment in the United States. The SEC’s fair value accounting framework, adopted under ASU 2023-08, now requires companies to report digital asset holdings at market value rather than historical cost, providing greater transparency into the actual financial exposure these positions represent.

Risks and Uncertainties

Several factors warrant caution when evaluating the significance of SpaceX’s Bitcoin position. The cryptocurrency market remains inherently volatile, and the unrealized gain recorded at March 31 could shift materially depending on Bitcoin’s price at the time of the IPO. Corporate Bitcoin holdings carry concentration risk, and a prolonged downturn in digital asset markets could affect investor sentiment around the offering.

The accuracy of the Arkham Intelligence estimate, which significantly understated the actual holdings, also raises questions about the reliability of on-chain analytics for estimating corporate positions that may use multiple custodians or proprietary wallet structures. Additionally, the IPO valuation targets of $1.75 trillion to $2 trillion remain ambitious, and market conditions at the time of listing could affect pricing and demand. The combination of a record-breaking IPO with a substantial Bitcoin treasury position introduces multiple variables that prospective investors will need to evaluate independently.
