Strategy purchased 334 Bitcoin for $28.7 million in the four days through Oct. 4, lifting its total holdings to 848,000 BTC, the company disclosed Monday in its routine treasury update.

The acquisition deepens the firm's position as the largest corporate holder of Bitcoin and extends its ongoing capital-rotation program, which converts proceeds from equity issuance into digital-asset reserves.

How did Strategy fund the purchase?

The company split the funding between two sources:

• $15.7 million in net proceeds from sales of MSTR stock under its ATM (at-the-market) equity programs
• $13.0 million from its USD Cash position

Following the transactions, Strategy's aggregate cost basis for its Bitcoin holdings reached $63.97 billion. That equates to an average purchase price of $75,440.70 per BTC across the entire position — a benchmark the company reports each week under its disclosure practice.

What else moved on the balance sheet?

In the same reporting period, Strategy repurchased 740,634 shares of its STRC preferred stock for $73.7 million, according to the disclosure. The buyback points to active management of the firm's layered capital structure, which now spans common equity, preferred instruments and Bitcoin-backed credit.

As of Oct. 4, the company held:

• $4.88 billion in its USD Reserve
• $833.4 million in USD Cash

The combination gives Strategy roughly $5.7 billion in readily deployable liquidity for future Bitcoin purchases, debt service or additional STRC repurchases.

What does the growing stack mean for the company?

The enlarged 848,000 BTC position strengthens Strategy's influence in Bitcoin market structure — the company routinely accounts for a meaningful share of visible spot demand when its buying pace accelerates. It also raises the operational stakes.

A larger treasury means the firm's balance sheet carries proportionally greater exposure to Bitcoin's price volatility, which flows through to its earnings via fair-value accounting on digital assets. The average cost of $75,440.70 per BTC serves as a reference point for unrealized gains or losses on the position.

The concurrent STRC repurchase suggests management is balancing new Bitcoin accumulation with capital-return and liability-management considerations, rather than pursuing accumulation exclusively.

Investors should expect the next scheduled disclosure to reveal whether the pace of purchases — modest in this four-day window — accelerates as equity issuance proceeds rebuild.

This is a developing story.
