Michael Saylor has lost over $4 billion of personal wealth in the past six months as MicroStrategy (MSTR) stock and Bitcoin prices have slid.
According to an analysis of public data, his net worth is now roughly $5.9 billion as of November 18, 2025, a significant decrease from about $10.1 billion in mid-May.
This decline reflects a 52% plunge in MSTR stock during that period and weaker cryptocurrency markets. Forbes’s real-time tracker listed Saylor’s net worth as $10.1 billion on May 13, 2025, implying a roughly 40% drop by late November.
MSTR Stock Slump Drains Saylor’s Fortune
Saylor’s 19.640 million Class B MSTR shares remain his largest asset. These supervoting shares, each carrying 10 votes per share, grant him controlling power over MicroStrategy, now operating as Strategy Inc.
As of May 2, 2025, Saylor held exactly 19,616,680 Class B shares. At recent MSTR stock prices, that stake is valued at approximately $3.9 billion, roughly half of its value from six months prior.
In other words, the decline in MSTR stock has erased about $4.1 billion of value from Saylor’s stake. Despite this drop, his Class B position continues to dominate his net worth.
MSTR stock closed sharply lower in November 2025, extending its six-month slide. The stock has lost over half of its peak value, mirroring broader market pressures on Bitcoin-related stocks.
MicroStrategy (MSTR) shares are now trading at a significant discount to the value of the company’s Bitcoin treasury, reversing much of the "Bitcoin premium" they once commanded.
Beyond the company’s stock, Saylor holds a substantial personal Bitcoin position. He publicly disclosed in 2020 that he personally acquired 17,732 BTC for approximately $175 million.
This amount appears to be unchanged; in August 2024, Saylor confirmed he still held 17,732 BTC. At current prices, those coins are worth roughly $1.6 billion. This personal crypto holding is separate from Strategy Inc’s corporate treasury.
Saylor also owns numerous private assets. He reportedly controls tens of millions of dollars in real estate and luxury yachts, as well as valuable Internet domain names.
These non-public holdings, along with any private equity or art, are more difficult to value but bolster his wealth beyond his stock and Bitcoin holdings. Forbes’s latest estimate likely includes these assets, given that it places his overall net worth at $5.9 billion.
Strategy Insider Sales and Net Worth Outlook
Notably, Saylor has not sold any MSTR stock in recent quarters. He did exercise and sell company stock under a previously disclosed plan in April 2024, but since then, he has not filed any Form 3 or 4 to disclose insider trades.
This absence of new sales implies his 19.616 million Class B shares are still intact. In short, his stake and voting power in the company appear unchanged.
Putting the pieces together, Saylor’s wealth today comes chiefly from his remaining MSTR stake and Bitcoin. Forbes’s November 2025 estimate of $5.9 billion essentially matches the sum of $3.9 billion (stock) plus $1.6 billion (personal BTC), plus modest gains from real estate and other assets.
In practical terms, his net worth is roughly half of what it was in May, driven largely by the 52% drop in MSTR stock and a slide in Bitcoin price.
Despite the steep losses, Saylor’s public outlook and ownership haven’t wavered. He continues to hold the same positions, and Strategy Inc’s Bitcoin strategy remains central to the company.
Strategy reported on November 17 that it had added 8,178 BTC to its treasury in a deal worth about $835 million—its largest purchase since July 29, when it acquired 21,021 coins.
With the latest transaction, the Virginia-based firm’s total Bitcoin investment rose to $59.40 billion, giving it an average purchase price of $74,433 per coin. The company now holds 649,870 BTC, representing roughly 3.1% of Bitcoin’s eventual fixed supply.
