SpaceX’s S-1 filing with the SEC has revealed the aerospace giant holds 18,712 BTC, worth approximately $1.45 billion, marking the company’s first official acknowledgment of digital asset holdings and positioning it among the world’s largest corporate Bitcoin treasury holders as it prepares for what could become the largest IPO in history.
The disclosure, filed on May 20, 2026, shows SpaceX acquired its Bitcoin position for roughly $661 million, implying an average cost basis of approximately $35,300 per BTC. The filing reported a fair value of $1.293 billion as of March 31, 2026, with the position appreciating to around $1.45 billion by the filing date. This represents an unrealized gain of approximately $790 million, or roughly 120 percent above cost basis, demonstrating substantial appreciation despite Bitcoin’s well-documented volatility over recent years.
The revelation places SpaceX in an elite cohort of public companies with significant Bitcoin exposure.
Strategy (MSTR) remains the undisputed leader with over 843,700 BTC, but SpaceX’s holdings now exceed those of Coinbase Global (approximately 15,000 BTC) and rival positions held by major Bitcoin mining companies and dedicated treasury vehicles. The disclosure is particularly notable given that SpaceX’s stack surpasses that of Tesla, another Elon Musk-controlled entity, which holds an estimated 11,500 BTC after previous partial sales.

The S-1 filing comes as SpaceX prepares for a Nasdaq listing under the ticker SPCX, with a targeted valuation approaching $1.75 trillion. While the Bitcoin holdings represent less than one percent of the company’s implied enterprise value, the disclosure adds a new dimension to SpaceX’s investment thesis, blending aerospace innovation, artificial intelligence infrastructure, and digital asset exposure under one corporate umbrella. The filing also revealed that Musk will retain approximately 85 percent voting control post-IPO through a dual-class share structure, alongside disclosures of significant AI-related investments and operational losses in 2025.
Other notable holders of BTC
Other public company’s with hefty BTC treasuries include Twenty One Capital (XXI), holding ~43,000 BTC and having positioned itself as a pure-play Bitcoin treasury company following its SPAC listing. Japan-listed Metaplanet maintains roughly 30,000 to 35,000 BTC, representing one of Asia’s largest corporate positions. Bullish (BLSH), a public cryptocurrency exchange, reports around 23,000 BTC on its balance sheet, while dedicated Bitcoin mining companies Marathon Digital (MARA) and Riot Platforms (RIOT) hold ~35,300, and 15,600 respectively.
Newer entrants to the Bitcoin treasury space include Strive (ASST), which has accumulated approximately 14,000 BTC through equity-for-Bitcoin transactions and cash-rich acquisitions, and mining operators Hut 8 (HUT) and CleanSpark (CLSK), each holding between 13,000 and 16,000 BTC. Even culturally significant names like Trump Media & Technology Group (DJT) and GameStop (GME) now appear on corporate Bitcoin holder lists with approximately 9,000 and 4,000 BTC respectively, broadening the narrative beyond traditional technology and financial services sectors.
The strategic rationale for corporate Bitcoin treasuries varies across these entities. For Strategy, Bitcoin represents the primary treasury reserve asset, with the company continuously raising capital through convertible debt and equity offerings to acquire additional coins. Mining companies like Marathon and CleanSpark view their Bitcoin holdings as both operational inventory and strategic reserves, though operational pressures occasionally force partial sales. For SpaceX, the Bitcoin position appears to function as a diversified treasury asset alongside traditional cash and short-term investments, rather than a core business focus.
BTC Backdrop
The macro backdrop for corporate Bitcoin strategies has shifted considerably since the initial wave of adoption in 2020-2021. Inflation concerns, central bank policy uncertainty, and questions about the long-term trajectory of fiat currency purchasing power initially motivated many corporate Bitcoin allocations. However, the subsequent Federal Reserve tightening cycle, cryptocurrency market volatility, and high-profile industry failures in 2022 tested the conviction of corporate holders. Companies that maintained or expanded their positions through this period (including SpaceX, based on its disclosed cost basis) demonstrated sustained commitment to the strategy despite adverse near-term conditions. Many of which have been rewarded over time.
For equity markets, the emergence of a distinct “Bitcoin treasury” category creates opportunities and challenges for portfolio managers and analysts. Traditional valuation frameworks struggle to appropriately value companies where a significant portion of assets consists of a volatile, non-cash-flowing digital commodity. Some analysts apply net asset value approaches that mark Bitcoin holdings to market and assess operating businesses separately, while others incorporate Bitcoin price sensitivity into earnings models through fair value adjustments. The lack of standardized methodology creates dispersion in price targets and recommendations across the sector, contributing to elevated volatility in share prices relative to underlying Bitcoin moves.
Looking at the broader cryptocurrency market structure, corporate treasury demand represents a fundamentally different source of Bitcoin buying pressure compared to retail speculation or trading activity. Treasury allocations tend to be long-term holds with low turnover, effectively removing coins from liquid supply and potentially supporting prices during periods of weak retail demand. The aggregate holdings of the top 20 corporate Bitcoin treasuries now exceed 1 million BTC, roughly five percent of the total supply, creating a meaningful supply constraint that could amplify price movement in either direction.
What Next For SpaceX
SpaceX stands at the intersection of multiple transformative technology narratives: commercial space exploration, artificial intelligence infrastructure, and digital asset adoption. The company’s Bitcoin holdings add another dimension to an already complex investment story, appealing to investors who view these trends as complementary expressions of technological progress and institutional change. However, this complexity also creates analytical challenges, as investors must weigh the relative importance of launch cadence, satellite deployment, AI computing capacity, and Bitcoin appreciation within a unified valuation framework.
As the latest soon to be listed holder of BTC valued above $1B, SpaceX is in rare company. The path forward for SpaceX’s Bitcoin strategy post-IPO remains uncertain, with public company dynamics differing from private ownership, although with Elon Musk’s substantial ownership, any change that may come in future is likely to be driven by his own views rather than that of markets.
