Strategy bitcoin holdings climbed to 847,666 BTC after the company bought 1,665 coins last week. The firm, formerly MicroStrategy, paid about $142.7 million for them.
The purchases took place between 21 and 27 September, according to a Form 8-K filing on 28 September. Strategy paid an average of $85,681 per bitcoin, including fees.
Across all its holdings, the company has now spent $63.95 billion. That puts its average cost at $75,437 per coin.
It was the second weekly purchase in a row. In the prior week, Strategy bought 950 BTC at an average of $79,670, based on its 21 September filing.
How Strategy bitcoin buying resumed
The recent buying follows a notable pause. In early August, Strategy sold bitcoin in two straight weeks. It sold 1,638 BTC in the week to 2 August and 1,690 BTC the following week.
Those sales came at prices near $64,000. Then, in the week to 30 August, the company bought back 4,603 BTC at an average of $80,318.
Consequently, holdings have climbed back above their late July level of 843,775 BTC. They had dipped to 840,447 BTC in mid-August.
The company also tracks its purchases on its website dashboard. That page matched the filing’s figures for the latest week.
How Strategy paid for the coins
Strategy funded the bitcoin with sales of its common stock. It sold 1,469,165 MSTR shares through its at-the-market programme, raising $246.2 million in net proceeds.
Of that, $142.7 million went to bitcoin. The remaining $103.5 million went toward buying back its STRC preferred stock.
Based on those figures, Strategy sold its shares at an average of about $167.60 each, a Catenaa estimate. The stock closed at $157.14 on Monday.
Notably, the company sold no preferred shares at all during the week. Its STRF, STRC, STRK and STRD programmes were all idle.
In addition, the preferred programmes still hold large unused capacity. STRC alone has about $17.5 billion left, while STRD has about $4.0 billion.
Plenty of capacity remains. Strategy still has about $18.8 billion available to sell under its common stock programme.
Buying back its own preferred stock
Strategy repurchased 1,534,530 STRC shares for $151.7 million. That works out at about $98.86 per share, slightly below the $100 stated amount.
To fund the buyback, it used the $103.5 million from share sales plus $48.1 million of cash. As a result, its USD Cash balance fell to $1.00 billion.
That cash pile has shrunk steadily. It stood at $1.59 billion in late August, so it has fallen by about $590 million in five weeks.
Why buy back preferred stock? STRC currently pays a 12.00% dividend rate. Therefore, retiring shares below their $100 stated amount cuts a costly stream of payments.
Buybacks have become a weekly habit. Strategy has repurchased between $136 million and $177 million of STRC in each of the past six weeks.
Dividends remain a steady drain as well. During the week, Strategy used $22.1 million from its USD Reserve to pay preferred dividends.
Meanwhile, $723.5 million remains under its preferred stock repurchase programme. Separately, its USD Reserve for dividends stood at $5.02 billion.
The company also plans to move to daily dividend record dates for its preferred shares. A special shareholder meeting on the change is expected on 28 October.
What the numbers mean
The latest Strategy bitcoin purchases cost far more than its average. The company paid $85,681 per bitcoin, about 14% above its average cost.
Even so, the whole stack still shows a paper profit. At Monday’s Kraken close of $83,463, the holdings were worth about $70.8 billion, a Catenaa calculation.
That is roughly $6.8 billion, or about 11%, above what Strategy paid. However, the cushion is far thinner than it was when bitcoin traded near its January high.
Bitcoin itself has been choppy. It closed at $83,463 on Monday, below the average price Strategy paid during the week. In other words, the new coins already show a small paper loss.
Investors have noticed the pressure. MSTR shares closed at $157.14 on Monday, down 0.9% on the day. A week earlier, they had closed at $168.50, according to Nasdaq data.
Over the full year, the stock has held up better. It is about 3% above its end-2025 close of $151.95, although it has traded between $82.31 and $195.94.
