Saylor congratulated Elon Musk on SpaceX’s public listing and used the moment to point out that two Musk-led companies in his expanded “Mag8” group already hold bitcoin. He said that leaves 25% of the group with BTC on the balance sheet.
Saylor said two of Elon Musk’s big companies already keep bitcoin like a company piggy bank. Since SpaceX went public, that means 1 out of 4 of his “Mag8” group now has bitcoin too.
Analysis
What happened
Strategy chairman Michael Saylor used X to congratulate Elon Musk after SpaceX’s Nasdaq debut and to make a broader point about corporate bitcoin adoption. In Saylor’s framing, 25% of the firms in his expanded “Mag8” group now hold bitcoin on their balance sheets.
What is the “Mag8”
Saylor appears to be extending the widely used “Magnificent Seven” label by adding SpaceX as an eighth member. The group he is referring to includes Apple, Microsoft, Nvidia, Alphabet, Amazon, Meta, Tesla, and now SpaceX.
The bitcoin angle
According to the article, both Tesla and SpaceX already held bitcoin before SpaceX’s IPO. CoinDesk cites BitcoinTreasuries.net for the figures: SpaceX holds 18,712 BTC, while Tesla holds 11,509 BTC. That makes SpaceX the eighth-largest public bitcoin holder, and Strategy remains by far the largest public holder with 845,256 BTC worth more than $54 billion.
Why Saylor’s post matters
The post is less about a single tweet and more about the normalization of bitcoin on corporate balance sheets. Saylor has long argued that bitcoin is a treasury asset, and here he is linking that idea to some of the most visible companies associated with Musk and the U.S. tech market.
The article does not claim that other Mag8 members are moving toward bitcoin. It only shows that, within Saylor’s version of the group, two companies already have exposure and one of them just entered the public markets.
Key points
- Michael Saylor congratulated Elon Musk on SpaceX’s Nasdaq debut.
- Saylor said 25% of his expanded “Mag8” group now holds bitcoin.
- The article says Tesla and SpaceX already had bitcoin before SpaceX went public.
- CoinDesk cites 18,712 BTC for SpaceX and 11,509 BTC for Tesla.
- Strategy remains the largest public bitcoin holder at 845,256 BTC.
If more high-profile companies follow Tesla and SpaceX, bitcoin could gain even more legitimacy as a treasury asset. That may encourage other public firms to study or copy the approach.
The story is still based on a small number of companies, so it does not prove broad corporate adoption. If bitcoin prices fall sharply, holding it on a balance sheet could become a bigger source of risk rather than a sign of strength.
