Strategy Boosts USD Reserves by $300M, Adds 520 BTC

Strategy, the best-known corporate Bitcoin holder, has continued adding to its Treasury and bolstering its liquidity at the same time. According to a Monday 8‑K filing with the U.S. Securities and Exchange Commission, the company purchased an additional 520 Bitcoin for $34.9 million between June 15 and Sunday, bringing its total holdings to 847,363 BTC.

The same filing also points to a larger funding goal beyond the Bitcoin purchase: Strategy said it added $300 million to its U.S. dollar reserve, bringing that buffer to $1.4 billion. Investors have been watching both moves closely because Strategy’s capital-raising approach—especially its use of equity sales—has become a reference point for other Bitcoin treasury companies.

Key takeaways

• Strategy bought 520 BTC for $34.9 million at an average price of $67,068 per Bitcoin, lifting total holdings to 847,363 BTC.
• Cumulative Bitcoin purchases now total $64.1 billion, implying an average acquisition cost of $75,651 per BTC.
• The company increased its U.S. dollar reserve by $300 million to $1.4 billion, with the balance including expected proceeds from unsettled ATM share sales.
• Strategy’s latest funding came from sales of its Class A common stock via its at-the-market (ATM) program, with $335.5 million raised during the reporting period.
• Strategy’s perpetual preferred stock (STRC), designed to trade around $100, slipped below $90 last week and remained volatile alongside MSTR shares.

New Bitcoin buy and updated treasury math

Strategy’s latest disclosed purchase appears as part of its ongoing Bitcoin accumulation program. In the 8‑K filing, the company states that it bought 520 BTC for $34.9 million during the period from June 15 through Sunday. The average price works out to $67,068 per Bitcoin.

That addition expands Strategy’s Bitcoin treasury to 847,363 BTC. Strategy also provided updated aggregate figures: its cumulative purchases total $64.1 billion, resulting in an average acquisition cost of $75,651 per Bitcoin. Those averages matter because they shape how investors think about the downside resilience of the company’s balance sheet and how efficiently Strategy is acquiring Bitcoin relative to prevailing market levels.

Beyond the immediate purchase, the filing underscores that Strategy continues to pair accumulation with liquidity management—an approach that can be as important as the Bitcoin number itself when corporate financing conditions or market volatility change.

Liquidity build: $300 million to the USD reserve

Alongside the Bitcoin purchase, Strategy said it added $300 million to its U.S. dollar reserve, raising the total to $1.4 billion. The company’s statement on X aligns with the 8‑K details, which specify that the USD reserve figure includes expected cash proceeds from its at-the-market (ATM) share sales that had not yet settled.

Strategy characterizes the reserve as a tool to support credit-related obligations, including dividend payments and debt coverage. In the 8‑K, the company said it plans to keep replenishing the USD reserve over time based on market conditions, with the objective of supporting the credit quality of its Digital Credit securities.

For holders and traders, this matters because reserve levels can influence how comfortable markets feel about Strategy’s ability to meet obligations during periods when equity funding becomes more expensive or when crypto prices swing sharply.

ATM share sales supply the cash for both goals

Strategy’s latest funding mechanics, as described in the filing, rely on its Class A common stock sales through an ATM equity program. The company raised $335.5 million during the reporting period, and the proceeds were split between the Bitcoin purchase and reserve build.

Of the $335.5 million, Strategy used $34.9 million to buy 520 BTC and allocated $300 million to the USD reserve. This structure keeps Strategy’s treasury growth closely tied to equity-market access, rather than depending solely on direct crypto-related financing.

Strategy’s financing decisions tend to draw attention precisely because it is one of the most active corporate buyers of Bitcoin and the largest listed corporate Bitcoin holder. As the firm has scaled its approach, it has effectively created a playbook for other Bitcoin treasury companies that want to combine crypto exposure with a tradable equity base.

STRC and MSTR volatility returns to focus

While Strategy’s filings provide the fundamentals, market pricing has also been part of the narrative. Ongoing volatility in Strategy’s share complex has remained in focus, particularly after the company’s perpetual preferred stock STRC—intended to trade near $100—fell below $90 last week.

Market data cited in the report shows MSTR shares down 3.46% to $112.53 at Thursday’s close, ahead of Friday’s market holiday, based on Yahoo Finance data. STRC declined 0.46% to $88.59 at Thursday’s close, and it traded at $90.59 during Monday’s premarket session.

Bitcoin advocate Samson Mow commented on X that STRC has a “self-repairing mechanism” that activates when the security trades below its $100 reference level. He said the process includes a stop in issuing new shares through the ATM program when the price falls under that threshold, effectively limiting new supply. Mow also argued that lower prices can increase the relative yield for buyers versus their entry price, which may encourage demand and help move STRC back toward $100.

The substance investors are likely watching is whether the structure’s incentives translate into sustained stabilization as market conditions evolve. If STRC pricing continues to deviate materially from the intended reference zone, traders may focus less on the theoretical mechanism and more on how quickly the market absorbs limited supply and whether equity-market conditions remain supportive.

Why this funding package matters to Bitcoin markets

Strategy’s combination of new Bitcoin purchases and reserve replenishment is more than an internal balance-sheet update. For the wider market, it signals ongoing corporate appetite for Bitcoin, even as equity prices and preferred-share pricing swing. At the same time, the company’s reliance on ATM equity sales highlights a key dependency: continued BTC accumulation is increasingly tied to how quickly and cheaply Strategy can access public markets.

That linkage becomes especially relevant when the company’s own share-linked instruments—like MSTR and STRC—show volatility. The latest disclosures and market moves together reinforce a central theme for corporate Bitcoin: treasury strategies can be durable, but their execution depends on liquidity and funding channels that may fluctuate with sentiment and broader market conditions.

Next, readers should watch whether Strategy’s reserve build translates into steadier market confidence around its Digital Credit-related objectives, and whether STRC’s “self-repairing” incentives prove effective as its trading price interacts with the $100 reference level.
