MicroStrategy co-founder and executive chairman Michael Saylor announced that a quarter of the so-called “Mag8” companies now hold Bitcoin on their balance sheets, a milestone he tied to the historic initial public offering of Elon Musk’s SpaceX.
The Mag8 is Saylor’s extension of the well-known “Magnificent 7” tech stocks – Apple, Microsoft, Alphabet, Amazon, Nvidia, Meta, and Tesla – adding SpaceX, which went public on June 13, 2026. The listing was the largest in history, with a $75 billion offering at $135 per share.
In a post on X, Saylor congratulated Musk on the IPO and highlighted that 25% of the Mag8 now carry BTC. While he did not name the specific firms or disclose holdings, it is publicly known that Tesla and SpaceX are among the corporate Bitcoin holders. MicroStrategy itself remains the largest public holder with over 214,000 BTC.
The statement underscores the accelerating institutional adoption of Bitcoin as a treasury asset, a trend that began in earnest with MicroStrategy’s purchases in 2020. When top-tier technology companies allocate balance sheet reserves to Bitcoin, it signals confidence in the digital asset’s store-of-value properties and can further legitimize crypto in corporate finance, potentially attracting more institutional capital.
