Michael Saylor Says 25% of the Mag8 Now Holds Bitcoin After SpaceX Reveals 18,712 BTC

• SpaceX disclosed 18,712 BTC through its IPO filing, making it one of the world’s largest corporate Bitcoin holders.
• Tesla holds 11,509 BTC, bringing the combined Bitcoin reserves of the two companies to 30,221 BTC.
• Michael Saylor highlighted that 25% of the Magnificent 8 technology companies now hold Bitcoin on their balance sheets.
• Most major technology firms remain absent from corporate Bitcoin treasury adoption despite growing institutional interest.

SpaceX IPO Filing Expands Bitcoin’s Presence Among Major Technology Companies

Bitcoin has gained a larger foothold among the world’s most valuable technology companies following SpaceX’s public market debut and the disclosure of its Bitcoin treasury holdings.

On June 13, Strategy Executive Chairman Michael Saylor pointed out that two of the eight companies in the so-called Magnificent 8 technology group now hold Bitcoin as a treasury asset. His comments came after SpaceX officially disclosed its Bitcoin position through IPO documentation.

According to the filing, SpaceX holds 18,712 BTC on its balance sheet, representing one of the largest corporate Bitcoin positions globally. The disclosure provided the first official confirmation of the company’s Bitcoin holdings and placed the value of the treasury at approximately $1.29 billion as of March 31, 2026.

The revelation immediately positioned SpaceX ahead of Tesla among publicly traded technology companies with Bitcoin exposure and strengthened Bitcoin’s presence within the elite group of mega-cap technology firms.

Tesla and SpaceX Account for Bitcoin Exposure Within the Mag8

The Magnificent 8, commonly referred to as the Mag8, includes Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, Tesla, and SpaceX.

Among those companies, only Tesla and SpaceX have publicly disclosed Bitcoin holdings. Tesla currently holds 11,509 BTC, while SpaceX reported ownership of 18,712 BTC, bringing their combined holdings to 30,221 BTC.

Tesla first added Bitcoin to its balance sheet in 2021 and remains one of the earliest major technology firms to adopt the asset as part of its treasury strategy. Although the company sold a portion of its holdings in 2022, it has retained a substantial Bitcoin position.

SpaceX also began accumulating Bitcoin during the same period. According to its IPO filing, the company acquired its Bitcoin treasury at an average purchase price of approximately $35,320 per BTC and has continued to hold the asset on its balance sheet.

The combined holdings make Tesla and SpaceX the only Mag8 members with direct Bitcoin treasury exposure, drawing renewed attention from investors monitoring corporate adoption of digital assets.

Big Tech Remains Largely Absent From Bitcoin Treasuries

Despite SpaceX’s disclosure, most members of the Magnificent 8 have yet to report any Bitcoin holdings. Alphabet, Amazon, Apple, Meta, Microsoft, and Nvidia have not publicly disclosed Bitcoin as a treasury asset.

The situation highlights a growing divide between companies that have embraced Bitcoin as part of treasury management strategies and those that continue relying on traditional cash reserves and investment portfolios.

While institutional interest in Bitcoin has expanded significantly in recent years, the largest technology companies have largely remained on the sidelines. Microsoft shareholders have previously considered proposals related to Bitcoin treasury adoption, but the company has not announced any direct Bitcoin holdings. As a result, Tesla and SpaceX remain the only confirmed Bitcoin holders within the Mag8 group.

Corporate Bitcoin Holdings Reach New Milestones

SpaceX’s disclosure comes amid continued growth in corporate Bitcoin adoption worldwide. According to BitcoinTreasuries data, publicly traded companies collectively hold approximately 1.26 million BTC, valued at roughly $80.56 billion based on current market prices. The number of public companies holding Bitcoin has increased to 199, while aggregate corporate holdings have risen by approximately 3% over the past 30 days.

The figures reflect a broader trend of corporations incorporating Bitcoin into treasury management strategies as institutional participation in digital assets continues to expand.

Strategy remains the largest corporate Bitcoin holder with 845,256 BTC. Other significant holders include Twenty One Capital with 43,514 BTC, Metaplanet with 40,177 BTC, and MARA Holdings with 35,303 BTC.

The combined holdings of public companies now account for a meaningful portion of Bitcoin’s fixed maximum supply of 21 million coins, underscoring the growing role of corporate treasuries within the broader Bitcoin ecosystem.

SpaceX Disclosure Marks Another Milestone for Corporate Bitcoin Adoption

SpaceX’s IPO filing has provided investors with one of the clearest disclosures yet of Bitcoin ownership among major technology-related companies.

The filing not only expanded Bitcoin’s representation within the Magnificent 8 but also increased transparency around corporate digital asset ownership. Together, Tesla and SpaceX now hold more than 30,000 BTC, making them the only members of the group with publicly disclosed Bitcoin reserves.

As public companies continue increasing their Bitcoin exposure, SpaceX’s disclosure represents another significant milestone in the evolution of corporate Bitcoin adoption. The development also prompted Michael Saylor to note that 25% of the Magnificent 8 now holds Bitcoin on corporate balance sheets.
