Michael Saylor Joins Bloomberg Billionaires Index With $7.37 Billion Net Worth

Michael Saylor has finally made his way into the Bloomberg Billionaires Index, joining the ranks of global billionaires with wealth tied directly to Bitcoin.

Good to Know

• Saylor’s net worth reached $7.37 billion in September 2025, placing him at 491st worldwide.
• His fortune is closely linked to Strategy’s 636,505 BTC treasury, the largest corporate stash of Bitcoin.
• Strategy has invested $46.1 billion in Bitcoin since 2020 at an average cost of $73,288 per coin.

The co-founder and executive chairman of Strategy, among the Bitcoin community known for his “21 Rules of Bitcoin,” has seen his wealth climb by $1 billion since January 2025. Bloomberg’s data shows Saylor controls around $650 million in cash and holds $6.72 billion worth of company stock.

His fortune moves in sync with Bitcoin, making him one of the most crypto-exposed billionaires on the planet. At present, Bitcoin trades near $111,000, down 4.3% in the past 30 days, a price swing that directly impacts Saylor’s ranking.

A Fortune Built on Bitcoin

Saylor founded Strategy (originally MicroStrategy) back in 1989, but it was the firm’s decision to pivot toward Bitcoin in 2020 that reshaped both the company’s profile and his own net worth.

As of August 2025, Strategy had acquired 628,946 BTC valued at around $76 billion, spending roughly $46.1 billion to build its treasury. With the most recent purchases in August and September, the total now sits at 636,505 BTC.

Recent Buying Spree

Strategy hasn’t slowed down in 2025. The company made several large purchases in recent months:

1. Sept. 2: 4,048 BTC at $110,981 each ($449.25M)
2. Aug. 25: 3,081 BTC at $115,829 each ($356.87M)
3. Aug. 18: 430 BTC at $119,666 each ($51.46M)
4. Aug. 11: 155 BTC at $116,401 each ($18.04M)

It’s buying spree surely won’t be over, as there will be plenty of opportunities left this year for the firm.
