Michael Saylor congratulated Elon Musk after SpaceX’s historic IPO and said 25% of the Mag8 now holds bitcoin on corporate balance sheets. His comments underscored bitcoin’s expanding presence within the upper ranks of the technology sector as more major companies add BTC to their treasuries.

Key Takeaways:

• • Strategy’s Michael Saylor said 25% of the Mag8 now holds bitcoin on corporate balance sheets.

• • Corporate bitcoin treasury strategies continue expanding across public and private firms.

SpaceX IPO Puts Saylor’s Mag8 Bitcoin View in Focus

Michael Saylor congratulated Elon Musk after SpaceX (Nasdaq: SPCX) completed a historic public listing, tying the IPO to bitcoin ownership among mega-cap technology companies. The Strategy (Nasdaq: MSTR) executive chairman posted the message on X on June 13. His post linked SpaceX’s market debut to the growing number of major companies holding bitcoin on their balance sheets.

Saylor wrote:

“Congratulations Elon Musk and $SPCX on a historic IPO. Thanks to you, 25% of the Mag8 now holds Bitcoin on the balance sheet.”

SpaceX entered public markets after extraordinary demand for its shares. The record IPO reportedly drew more than $350 billion in demand against a planned $75 billion offering. The listing made Musk the world’s first trillionaire and valued SpaceX at about $2.1 trillion, placing it among the world’s largest technology companies.

The Mag8 expands on the Magnificent Seven, or Mag7, a group consisting of Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, and Tesla. Saylor’s post effectively added SpaceX to that lineup following its historic IPO, reflecting the company’s emergence as one of the market’s largest and most closely watched technology businesses.

Strategy, Tesla, and SpaceX Lead the Bitcoin Treasury Spotlight

Corporate bitcoin treasuries now include public companies, private firms, miners, exchanges, and balance-sheet-focused vehicles. A recent ranking showed the top 100 bitcoin treasuries holding a combined 1,258,090 BTC. Major names include Strategy, Tesla, SpaceX, Coinbase, Riot Platforms, Block, Galaxy Digital, and Hut 8.

Strategy remains the largest corporate holder of bitcoin, with 845,256 BTC on its balance sheet. The company has funded its bitcoin purchases through debt, equity, and preferred-stock offerings.

Tesla and SpaceX rank among the largest corporate bitcoin holders, and Saylor counted both companies within his Mag8 framing. Tesla holds 11,509 BTC, while SpaceX holds 18,712 BTC worth roughly $1.2 billion at current prices.

Treasury-company concerns have centered on leverage, dividend obligations, and potential BTC selling during weaker markets. Capriole Investments founder Charles Edwards warned that bitcoin treasury companies are “levering up at record rates.” Grayscale separately warned Strategy may face constraints on future bitcoin purchases if market conditions weaken.

Saylor has continued to describe bitcoin through a broad institutional framework. He outlined four bitcoin ideologies: Maximalists, Capitalists, Technologists, and Fundamentalists. His framework presented BTC as corporate capital, bank collateral, national reserves, and infrastructure for financial markets.
