Saylor's Strategy Sees $1.8 Billion Unrealized Gain on Bitcoin Holdings

As of September 18, 2026, Michael Saylor's Strategy (MSTR.US) has seen significant growth in its Bitcoin holdings. The company disclosed that it now holds approximately 845,050 BTC, acquired at a total cost of around $64.27 billion. This puts the average cost per BTC at around $76,052.

With the current price of Bitcoin (BTC.CC) standing at $78,182, Strategy's unrealized gain comes out to around $1.80 billion. This represents a 2.8% increase over the company's cost basis.

This development is significant because it means that the current price of BTC has climbed above MSTR's overall BTC cost basis, which was around $76k. For every $1,000 rise in BTC, the book value of MSTR's BTC holdings increases by approximately $845 million.
