Bitcoin's price has climbed back to $85,000, marking its highest level since January and representing a rebound of nearly 30% from its August lows. Against this backdrop, Strategy (ASX: MSTR) and Strive (ASX: ASST) collectively deployed $183 million into Bitcoin purchases last week, standing out as the most significant corporate treasury allocation move in the current cycle.

This buying spree signals not only an aggressive accumulation strategy following the recent price correction but also reaffirms the dominant position of leading players amid a broader slowdown in corporate Bitcoin acquisition activity. As BTC breaks through this critical psychological level, balance sheets that had been under pressure from earlier price declines are now positioned for recovery. The counter-cyclical purchases by Strategy (ASX: MSTR) and Strive (ASX: ASST) represent a clear response to the ongoing revaluation of market prices and offer a directional signal for future capital flows.

Looking at the transaction specifics, Strategy (ASX: MSTR) acquired 950 BTC between September 14 and 20 at an average price of $79,670 per coin, totaling $75.7 million. This move brings its total holdings back to 846,000 BTC, with an aggregate cost basis of $63.8 billion and an average acquisition price of $75,416 per coin. Meanwhile, Strive (ASX: ASST) purchased 1,355 BTC between September 14 and 18 at an average price of $79,475 per coin, spending $107.7 million and lifting its total position to 26,355 BTC. Notably, Strive (ASX: ASST) also saw its cash and equivalents balance rise to $229.6 million during the same period, reflecting an approach that maintains liquidity while expanding its asset base.

Data shows that publicly listed companies added roughly 5,900 BTC over the past three months, a figure far below the 89,000 BTC acquired in a single month back in July 2025, with the industry average purchase price sitting near $80,500. At the time of reporting, BTC's price had been trading below that cost line, leaving corporate holdings in an aggregate loss position. However, Monday's breakthrough above $85,000 has completely reversed that situation, pushing asset values back above the average acquisition cost.

The balance sheet transformation at Strategy (ASX: MSTR) has been particularly dramatic. At the end of the second quarter, when BTC stood at $58,714, the company recorded a loss of $8.32 billion, with $8.31 billion of that representing unrealized losses. Based on a price of $85,000, its 846,000 BTC holdings would be valued at approximately $71.9 billion, exceeding the total acquisition cost by roughly $8.1 billion and surpassing the value corresponding to its June 30 closing price by more than $2.2 billion. While frequent buying and selling activity within the quarter causes fair value changes to be marked to market in real time, making it difficult to directly reflect final accounting profits, there is no doubt that the price rebound has delivered a massive restorative effect on the balance sheet.

To manage the securities supporting its BTC assets, Strategy (ASX: MSTR) spent $174 million last week to repurchase 1.77 million shares of its floating-rate STRC preferred stock and drew $57.4 million from reserves to cover dividends and interest payments. As of September 20, its reserves stood at $5.04 billion, with an additional $1.05 billion in cash. The CEO stated in July that buying back shares below par value would ease dividend pressure and support the sustainability of the preferred stock market. Since then, the company has spent approximately $1.1 billion in cumulative STRC repurchases. Having gone two weeks without mentioning Bitcoin purchases, with holdings at 845,050 coins as of September 13, this latest acquisition suggests Strategy (ASX: MSTR) has found a new equilibrium between balance sheet management and BTC accumulation.

The operations at Strive (ASX: ASST) reveal a different financing logic. Prior to the latest round of purchases, the company had already acquired 469 BTC last week and 1,375 BTC in early September, demonstrating a heavy reliance on SATA preferred stock financing. Warrant exercises brought in approximately $21.2 million in capital flows last week, with SATA preferred shares rising to 57.7% of total fundraising. On the equity side, SATA outstanding shares increased by 786,194 to 11.18 million shares, while Class A shares grew by roughly 2.07 million. Strive (ASX: ASST) purchased its latest BTC at a price nearly $5,500 below $85,000, meaning its asset values sit closer to historical cost. This model becomes more sustainable when Bitcoin's price appreciation outpaces the cost of its securities.

Market analysis indicates that while tens of thousands of BTC were being purchased by corporations monthly in 2025, buying activity has now become concentrated among a handful of companies. With BTC rebounding above the $80,500 industry average cost, the renewed entry of Strategy (ASX: MSTR) and Strive (ASX: ASST) could trigger a chain reaction, prompting other corporate buyers who have been waiting on the sidelines to rejoin the purchasing wave and thereby unlocking further market liquidity.
