Strategy co-founder Michael Saylor congratulated Elon Musk after SpaceX’s historic Nasdaq debut on Friday, declaring that 25% of what he calls the “Mag8” now hold bitcoin on their balance sheets.
Saylor wrote on X:
“Thanks to you, 25% of the Mag8 now holds bitcoin on the balance sheet.”
Saylor’s expanded magnificent seven
The “Mag8” appears to be Saylor’s expansion of the widely tracked Magnificent Seven group — Apple, Microsoft, Nvidia, Alphabet, Amazon, Meta, and Tesla — with SpaceX added as the eighth member following its $1.75 trillion IPO, the largest public offering in history.
Both Musk-led companies in the group, Tesla and SpaceX, already held bitcoin before the listing went live.
SpaceX already a top bitcoin holder
SpaceX entered the public markets as the eighth-largest corporate bitcoin holder, with 18,712 BTC on its balance sheet.
Tesla holds 11,509 BTC.
Strategy remains the dominant leader among public companies, holding 845,256 BTC worth over $54 billion.
What it signals for corporate adoption
Saylor’s framing of a “Mag8” underscores how bitcoin treasury strategies have moved from niche corporate experiments to a feature of the world’s most valuable public companies.
With two of the eight largest firms now holding bitcoin, the pressure on remaining mega-caps to consider similar allocations could intensify.
