Michael Saylor Joins Billionaire Club
Michael Saylor, strategy co-founder and executive chairman, has made his first appearance on the Bloomberg Billionaires Index. This milestone comes as his net worth has risen by $1 billion since the start of the year to $7.37 billion, ranking 491st globally.
Wealth Surge and Bitcoin Accumulation
The wealth surge coincides with Strategy’s continued Bitcoin accumulation strategy and the cryptocurrency’s price movements throughout 2025. With 636,505 BTC as of September 2025, the firm has the most extensive corporate crypto treasury on record. 
Saylor’s Net Worth Breakdown
Saylor, who founded Strategy (previously known as MicroStrategy) in 1989, has $650 million in cash and $6.72 billion tied up in company stock, according to Bloomberg’s tracking methodology. The direct correlation between his wealth and cryptocurrency markets makes him one of the most Bitcoin-exposed billionaires globally.
Bitcoin Price and Strategy’s Purchases
Saylor’s debut comes as Bitcoin trades around $111,000, down about 4.3% over the last 30 days. Strategy’s first bitcoin purchase was in 2020. As of August 2025, it has accumulated 628,946 BTC — valued at roughly $76 billion — acquired at an average price of $73,288 per coin for a total investment of about $46.1 billion.
Recent Purchases
The most recent major purchase occurred on Sept. 2, when Strategy acquired 4,048 Bitcoin at an average cost of $110,981 per coin, spending $449.25 million. Earlier purchases in August included 3,081 BTC on Aug. 25 at $115,829 per coin for $356.87 million and 430 BTC on Aug. 18 at $119,666 each for $51.46 million. 
Crypto Billionaire Club
The company also bought 155 BTC on Aug. 11 at $116,401 per coin for $18.04 million. Saylor’s inclusion places him among other prominent cryptocurrency billionaires on Bloomberg’s list. Coinbase CEO Brian Armstrong ranks 234th with a net worth of $12.8 billion, while Binance founder Changpeng “CZ” Zhao holds the 40th spot with $44.5 billion.
Changes in the Crypto Billionaire Club
The crypto billionaire club has seen changes over time. Former FTX CEO Sam Bankman-Fried was previously on the list before his exchange collapsed in November 2022, wiping out his fortune and leading to criminal charges. Strategy’s aggressive accumulation strategy has made it a proxy for Bitcoin exposure among traditional investors.
Challenges and Lawsuits
Yet, it was also notably left out of the S&P 500 index inclusion in August. The company is also involved in a lawsuit with investors who allege that the company misled shareholders about the risks and financial impact of its strategy. Despite these challenges, Saylor’s debut on the Bloomberg Billionaires Index marks a significant milestone for the executive chairman and Strategy.
