Strategy Inc, the business intelligence company that has become synonymous with corporate bitcoin accumulation, told the Securities and Exchange Commission in an 8-K filed October 5, 2026 that it purchased 334 bitcoin between October 1 and October 4 for approximately $28.7 million, pushing its total holdings to 848,000 BTC acquired at an aggregate cost of $63.97 billion.
The filing also disclosed a $20.91 billion gain on digital assets for the three months ended September 30, 2026, a figure reflecting the mark-to-market accounting treatment Strategy applies to its bitcoin holdings under current accounting standards, which require the company to record both unrealized gains and losses on its treasury each quarter as bitcoin’s price moves.
Alongside the bitcoin purchase, Strategy repurchased shares of its STRC variable-rate preferred stock in two tranches: 1,033,168 shares for $102.6 million between September 28 and September 30, followed by 740,634 shares for $73.7 million between October 1 and October 4, for a combined $176.3 million in buybacks during the reporting period. The repurchases are part of Strategy’s broader capital management toolkit, which blends bitcoin purchases funded by new capital raises with opportunistic buybacks of its various preferred stock classes when market pricing presents an opening.
Strategy’s weekly disclosure cadence has made it the most closely watched name in the corporate bitcoin treasury sector, with analysts and investors parsing each filing for signals about the pace of accumulation, the average purchase price, and how the company is managing its growing stack of preferred equity instruments alongside its common stock. The $20.91 billion quarterly gain highlights just how sensitive the company’s reported earnings have become to bitcoin’s price swings, since the mark-to-market rules mean even modest percentage moves in bitcoin translate into multibillion-dollar swings on Strategy’s income statement given the size of its holdings.
With 848,000 BTC now on its balance sheet, Strategy remains by far the largest corporate holder of bitcoin globally, a position it has built over several years through a combination of convertible debt, equity offerings, and preferred stock issuances. The latest purchase and buyback activity suggests the company continues to run both sides of its playbook simultaneously, adding to its core bitcoin position while also managing the capital structure that funds it.
