Strategy, the bitcoin treasury company formerly known as MicroStrategy, bought 4,603 BTC for $369.7 million between August 24 and August 30, ending a 10-week buying pause that had been the firm’s longest hiatus since 2023.
The average purchase price was $80,318 per coin inclusive of fees, according to an SEC filing disclosed on Monday. Holdings rose from 840,447 to 845,050 BTC, acquired over time for $63.73 billion at a blended average cost of $75,412 per coin. At current prices near $82,000, the stockpile carries an unrealized profit of roughly $5.6 billion.
How it was funded
The $369.7 million bitcoin purchase was part of a four-way allocation. Another $151.8 million went to repurchase 1,557,177 shares of variable-rate STRC preferred stock. $50.7 million covered STRC dividend payments, and roughly $30 million went into the USD cash account. All of it was funded through MSTR stock issuance, not operating cash flow.
The STRC preferred buyback still has about $365 million of remaining capacity. An MSTR repurchase authorization of $1 billion sits unused on the balance sheet, giving the company flexibility for future operations. Michael Saylor, the company’s executive chairman, said in a post on X that USD duration – a measure of how long dollar assets can cover preferred dividends – rose 23 days to 4.0 years. STRC’s bitcoin credit tightened by 3 basis points to 56. The purchase did not come at the expense of the cash buffer built over the summer.
Strategy’s dollar duration metric has become a closely watched indicator for preferred shareholders. A duration of 4.0 years means the company’s liquid dollar assets can cover preferred dividend obligations for roughly four years at the current pace. The 23-day improvement came partly from the cash allocation and partly from the reduced STRC share count after the buyback.
The pause and what broke it
Strategy’s last confirmed purchase before this one was in late June, making the 10-week gap its longest since the company began its systematic bitcoin accumulation program in 2020. During the pause, bitcoin traded in a range between roughly $75,000 and $80,000, and the broader market contended with geopolitical uncertainty from the Iran war and its impact on oil prices.
The resumption coincided with a broader uptick in institutional demand. U.S. spot bitcoin ETFs recorded $731 million in net inflows on Wednesday, their strongest single day since January, with BlackRock’s IBIT drawing $454 million alone. The combined force of corporate treasury buying and ETF inflows pushed bitcoin above $82,000, its highest level since May.
The timing also reflects improved conditions for MSTR stock issuance. Strategy funds its purchases by selling shares into the market, and the stock has recovered from recent lows as bitcoin prices stabilized above $75,000. The model still depends on equity markets remaining open to ATM issuance, and MSTR saw some premarket selling pressure on the disclosure day – a reminder that each purchase announcement carries a short-term cost in equity dilution.
Where Strategy stands among corporate buyers
With 845,050 BTC on its balance sheet, Strategy remains by far the largest corporate holder of bitcoin. The firm’s next nearest competitor is Twenty One Capital, which holds a fraction of Strategy’s stockpile. Strive Asset Management, another bitcoin treasury firm, has signaled ambitions to become the second-largest public bitcoin holder but has not yet matched Strategy’s scale.
The blended cost basis of $75,412 per coin means Strategy is profitable at current prices, though not by as wide a margin as during the August peak when bitcoin touched $82,000. The company’s average acquisition cost has risen over the past year as it bought at progressively higher prices, narrowing the cushion against any pullback. A sustained drop below $75,000 would push the portfolio underwater on a mark-to-market basis, though Saylor has repeatedly said the company has no intention of selling.
The STRC preferred program, launched in late March 2026, raised about $21 billion and has become the primary funding vehicle for new purchases. The structure carries fixed dividend obligations, which is why the cash buffer and USD duration metric matter to Saylor. If bitcoin prices fall below the $75,000 range, the unrealized profit cushion thins and the preferred dividends become a larger share of the company’s financial commitments.
What it means for the market
Strategy’s buying pattern matters for more than one reason. The firm’s purchases are large enough to move the market on disclosure days, and the 10-week pause had been read by some traders as a signal that even the most committed corporate buyer had hit limits. The resumption argues against that reading, though the modest size of the purchase – $369.7 million is small relative to the firm’s prior quarterly buys – suggests caution rather than aggression.
For bitcoin holders, the story is straightforward: a major buyer is back in the market. For skeptics, the equity-funded model remains a leveraged bet on continued access to capital markets. The $75,412 average cost basis is the line in the sand – below it, the strategy gets uncomfortable. Above it, Saylor keeps buying. For now, the market is above it.
The broader question is whether Strategy’s return to buying will draw other corporate treasuries into the space. Several firms have explored bitcoin reserves since 2024, but none have matched Strategy’s commitment. The 10-week pause may have discouraged imitators, and the resumption may reassure them. Either way, Strategy’s filing this week sets the tone for how the corporate bitcoin narrative unfolds through the rest of 2026.
