Strategy Inc. has funded its latest $1 billion weekly Bitcoin purchase entirely through the sale of its "Stretch" perpetual preferred shares, marking a milestone for Michael Saylor's aggressive crypto treasury strategy. The company completed its 13th consecutive weekly purchase under this model, reinforcing its position as the largest corporate Bitcoin holder.

For the first time since launching the high-yield securities in July, Strategy relied solely on the Stretch preferred shares to fund the acquisition. The perpetual preferred shares, designed to offer investors ongoing yields without maturity dates, have become the company's primary vehicle for raising capital to buy Bitcoin.

The all-Stretch funding approach signals growing investor appetite for the hybrid securities structure. By financing the entire purchase through perpetual preferred shares rather than convertible notes or common stock, Strategy demonstrates the market's willingness to back its Bitcoin-focused treasury model at scale.

This milestone validates Saylor's strategy of using hybrid securities to fund Bitcoin acquisitions. The success of the Stretch preferred shares suggests investors are comfortable with the perpetual yield structure and confident in Strategy's ability to continue accumulating Bitcoin.
