Bitcoin treasury firm Strategy, formerly MicroStrategy, added another 15,355 BTC to its balance sheet over the past week.

The company spent about $1.42 billion at an average price of $92,737 per Bitcoin, according to an SEC filing Monday.

The purchase brings Strategy’s total Bitcoin (BTC) holdings to 553,555 BTC, worth over $52 billion at Bitcoin’s current price of just above $95,000. 

The company’s cumulative average purchase price now stands at $68,459 per Bitcoin, reflecting a total investment of around $37.9 billion, including fees. 

Strategy’s holdings account for more than 2.6% of Bitcoin’s fixed 21 million supply.

Meanwhile, competition in corporate Bitcoin accumulation is heating up. Firms such as Cantor Fitzgerald, SoftBank, Bitfinex, and Tether recently announced a $3.6 billion Bitcoin venture, while new entrants like Twenty One Capital, led by Strike CEO Jack Mallers, are launching with a Bitcoin-native strategy. 

Shares of Strategy’s MSTR closed 5.2% higher at $368.71 on Friday and are up another 1.42% in pre-market trading Monday. The stock has gained nearly 23% year-to-date, supported by Bitcoin’s price rebound and rising institutional interest in companies focused on Bitcoin.

Acquisition funding

Proceeds from the sale of its Class A common stock and perpetual preferred stock funded the latest acquisitions. Between April 21 and April 27, Strategy sold approximately 4 million shares of MSTR for about $1.4 billion, while also selling over 435,000 STRK shares for $37.5 million. 

Only $128.7 million worth of MSTR shares remain available for issuance under the company’s existing program.

The move comes a week after Strategy added 6,556 BTC for $555 million, signaling the company’s continued aggressive approach to growing its Bitcoin treasury.
