Strategy, the Nasdaq-listed bitcoin treasury company, has established a new U.S. dollar cash reserve that it may use to buy bitcoin, according to a Monday filing.

The company said it increased its usual cash buffer, the USD Reserve, to $5.10 billion and created an additional pool of $1.59 billion — designated as USD Cash — which it may deploy toward bitcoin and stock purchases.

Michael Saylor, the company's co-founder, announced the moves on X:

Strategy increased USD Reserve to $5.10B, established additional USD Cash of $1.59B, and repurchased $136M of $STRC . As of 8/23/26: Strategy holds ~4% of Total BTC Supply and has ~0% Net Leverage. $MSTR

The filing defined the new pool as follows: "USD Cash is a separately designated pool of U.S. dollar liquidity that the Company may retain for future deployment for general Bitcoin Treasury Company purposes, which may include acquiring bitcoin, paying declared cash dividends on Strategy's preferred stock and interest on its outstanding indebtedness, repurchasing Strategy's MSTR Stock or preferred stock, repaying, repurchasing or redeeming Strategy's outstanding convertible notes, increasing the USD Reserve, and other similar Bitcoin Treasury Company purposes." The filing does not set a timetable for when the pool might be deployed.

Strategy has not purchased bitcoin since June. Instead, it has focused on stock buy-backs and building a cash cushion, while occasionally selling bitcoin. The pause is a break from the steady stream of purchase announcements that marked much of the company's run since 2020 — buys that have been closely tracked in bitcoin markets as a gauge of corporate demand. The company has said its buyback plan, approved in July, is about balance-sheet strength rather than retreat, and President and CEO Phong Le has said Strategy intends to remain a long-term bitcoin buyer.

According to the filing, Strategy sold roughly $2 billion in common shares last week and repurchased $136.4 million of its Stretch preferred shares. Stretch (STRC) is one of the dividend-paying preferred instruments Strategy has issued to investors.

Shares of Strategy (Nasdaq: MSTR) were trading higher Monday morning in New York. The stock rallied last week as the price of bitcoin rose. Bitcoin recently stood at $79,031, up 25% over a seven-day period.

Strategy — the corporate software company formerly known as MicroStrategy, a name it retired in a 2025 rebrand — began buying bitcoin in August 2020 as a way to protect shareholder returns. It has since spent nearly $64 billion on the cryptocurrency, largely using leverage, and now holds 840,447 BTC worth $66.4 billion at current prices, making it the largest corporate holder of the digital coin. Because bitcoin's supply is capped at 21 million coins by its protocol, that stash works out to roughly 4% of all the bitcoin that will ever exist — the share Saylor cited in his post. Other listed companies have since adopted similar bitcoin treasury strategies. Investors can gain exposure to bitcoin through the stock and dividend-paying instruments that Strategy has issued.
