How Strategy’s $64B Bitcoin Buying Plan Uses High-Yield Funding to Target BTC Upside

Strategy, the firm formerly known as MicroStrategy, has quietly set up one of the largest potential Bitcoin buying war chests in public markets. A new at-the-market (ATM) securities filing expands its active issuance capacity to more than $64 billion, largely anchored by high-yield preferred stock that could both fuel aggressive BTC accumulation and increase long-term capital strain.

Inside Strategy’s expanded $64B issuance capacity

On March 23, Strategy filed an 8-K that reconfigured its equity and preferred stock funding channels, taking its total active securities issuance capacity to roughly $64.15 billion. The company did not raise this amount upfront; instead, it created the ability to “issue and sell” this volume over time as funding needs and market conditions evolve.

The new structure adds fresh capacity on top of existing prospectuses:

• Up to $21 billion of Class A common stock (MSTR)
• Up to $21 billion of STRC preferred stock
• Up to $2.1 billion of STRK preferred stock

These new lines sit alongside earlier ATM programs that Strategy intends to keep using until exhausted: about $15.85 billion in common stock capacity and $4.2 billion in STRC preferred stock capacity. A previous STRK line covering roughly $20.34 billion was terminated on March 22.

Aggregated, the still-active common equity and STRC programs, plus the new STRK line, bring Strategy’s total runway to more than $64 billion. The company also broadened its sales syndicate, adding Moelis, A.G.P./Alliance Global Partners, and StoneX to its omnibus agreement, which could support more flexible and diversified execution.

Given Strategy’s track record, the filing is widely interpreted as a roadmap for the next phase of its Bitcoin treasury strategy rather than a generic capital-raising exercise. The firm is already the largest public holder of Bitcoin, with 762,099 BTC acquired for about $57.7 billion, implying an average purchase price near $75,700 per coin. At current levels, data from SaylorTracker shows the position sitting on unrealized losses of more than $3 billion, underscoring the firm’s continued willingness to lean into volatility.

STRC vs. STRK: rebalancing the Bitcoin funding mix

The March 23 filing also marks a notable shift in how Strategy wants to finance future Bitcoin buys, significantly elevating STRC while slimming down STRK.

For STRC, Strategy filed to increase authorized shares of its Variable Rate Series A Perpetual Stretch preferred stock from 70,435,353 to 282,556,565 – an increase of 212,121,212 shares. STRC has become the centerpiece of Strategy’s preferred funding engine, offering a variable dividend yield of 11.5% and trading with deep liquidity since its 2025 launch.

In contrast, authorized STRK preferred shares were reduced sharply – from 269,800,000 to 40,270,744, a cut of 229,529,256 shares. The company also wound down the much larger prior STRK issuance program and replaced it with a smaller $2.1 billion capacity.

The divergence is significant because STRC and STRK sit differently in the capital structure. STRK is Strategy’s 8.00% Series A Perpetual Strike preferred stock, with a conversion feature allowing each STRK share to convert into 0.1000 shares of MSTR at an initial $1,000 per-share conversion price, subject to adjustment. That embedded call option on the common stock is unique among the company’s preferred offerings (STRD, STRK, STRE, STRC).

Previously, this convertibility helped drive speculative interest. STRK even traded as high as $129 in July 2025 – 29% above its $100 liquidation preference, on which Strategy pays an 8% dividend – before declining to $77 as of the time of the latest filing. By reducing both authorized STRK and its active issuance envelope, Strategy is dialing back a channel that mixes yield with upside participation in favor of an instrument that is more purely income-focused for investors.

This reweighting suggests a preference for STRC’s characteristics – high coupon, strong liquidity, and no equity conversion overhang – as the primary conduit for future Bitcoin funding.

Why STRC is becoming the engine of Bitcoin accumulation

Since its introduction, STRC has evolved into one of the most actively traded preferred securities in the market. According to data shared by Strategy chairman Michael Saylor, STRC now posts average daily trading volume of about $295.9 million. That liquidity exceeds the combined average daily volume of the seven closest competing preferred issues, including those from large traditional issuers such as Boeing, KKR & Co., and Four Corners Property Trust.

STRC offers a variable dividend yielding 11.5%, which has attracted institutional capital. Reported holders include BlackRock’s iShares Preferred and Income Securities ETF, Anchorage, and asset manager Strive. That depth of institutional participation stabilizes issuance and secondary trading, giving Strategy a scalable, repeatable way to raise cash for Bitcoin purchases.

Data from STRC.live indicates the program has already financed the acquisition of more than 50,000 BTC since inception. In effect, STRC functions as a high-yield financing tap: investors accept double-digit income in exchange for exposure to Strategy’s leveraged Bitcoin strategy via a preferred claim on cash flows, while the company channels proceeds directly into BTC.

By dramatically expanding authorized STRC shares and opening a fresh $21 billion issuance envelope, Strategy is signaling that this preferred stock has become its preferred engine for further Bitcoin accumulation.

How issuance math could translate into Bitcoin buying power

Beyond the headline totals, the structure of Strategy’s balance sheet means that preferred issuance alone does not tell the whole story. Bitcoin analyst Adam Livingston argues that the expanded STRC program could enable significantly more BTC buying than its face value implies when combined with common stock issuance.

On his analysis, Strategy seeks to keep a particular “amplification ratio” between its equity and preferred funding. At current settings, every $1 of STRC issuance would require about $1.94 of MSTR common stock issuance to hold that ratio roughly constant.

If STRC issuance were to continue at its recent pace of around $2 billion per month, maintaining the ratio would imply roughly $3.9 billion per month of incremental common equity issuance. Combined, that would translate into nearly $5.9 billion per month of potential Bitcoin purchases at current deployment patterns.

Under this framework, fully utilizing the new $21 billion STRC and $21 billion MSTR programs could finance the acquisition of more than 450,000 BTC over approximately five to seven months. Livingston notes that the common-stock leg would likely act as the bottleneck, limiting how fast this theoretical capacity could be tapped in practice.

Even if actual execution ends up materially smaller or slower, the scale of the envelope matters for markets. Strategy already owns over 762,000 BTC; a path to hundreds of thousands more coins, if pursued, would extend its role as a persistent structural buyer in spot markets.

High-yield funding, dividend drag, and capital structure risk

The same features that make STRC such a powerful funding tool also create growing obligations for Strategy’s capital structure. At an 11.5% variable dividend, a fully deployed $21 billion STRC program would carry a significant cash cost. Analyst Ivan Wu of The Block estimates that maxing out the STRC envelope would add roughly $2.4 billion in annual dividend obligations.

Strategy has attempted to mitigate this near-term by accumulating approximately $2.25 billion in USD reserves earmarked to fund preferred dividends. This buffer offers some protection against rising capital costs and Bitcoin price volatility, and it buys time for the thesis that long-term BTC appreciation will more than offset funding expenses.

However, credit-focused observers remain wary. Jeff Dorman, chief investment officer at Arca, argues that looking only at assets versus liabilities paints an incomplete picture. On his assessment, Strategy generates essentially zero earnings before interest and taxes, meaning it fails a core credit metric: interest coverage.

Without meaningful operating cash flow, the company’s ability to service debt and preferred dividends hinges on one of three paths: issuing more equity, selling Bitcoin, or defaulting on obligations. Dorman frames the trade-offs starkly: if Strategy never sells BTC, the debt and preferreds will eventually default; if it issues ever more stock to fund interest and dividends, existing shareholders are diluted; if it sells Bitcoin to support its capital structure, the very asset backing the thesis is drawn down.

Summarizing the dilemma, he notes that the bills – interest and dividends – require cash flow, and that cash must ultimately come from somewhere beyond paper gains on a volatile asset.

What this means for Bitcoin markets and investors

For crypto investors tracking institutional Bitcoin accumulation, Strategy’s latest filing reinforces two parallel dynamics: sustained potential buy-side pressure on BTC and rising financing risk concentrated in a single, highly visible actor.

On the supportive side, the more than $64 billion in active issuance capacity, anchored by an expanded STRC program, gives Strategy a clear roadmap to continue scaling its Bitcoin holdings. Even partial deployment of this capacity would imply sizable incremental demand, particularly in an environment where new BTC supply is structurally constrained by halving cycles.

At the same time, the model’s reliance on high-yield funding with limited operating cash flow introduces fragility. Elevated dividend obligations, sensitivity to equity market conditions for further ATM issuance, and the possibility of having to liquidate BTC to service the capital stack all represent important risk vectors.

For holders of Bitcoin, the near- to medium-term effect of Strategy’s approach could be supportive if the firm continues to act as a large, price-insensitive buyer. For holders of Strategy’s equity and preferreds, the bet is more complex: it effectively combines conviction in long-term BTC appreciation with tolerance for balance-sheet leverage, dilution risk, and the possibility that capital markets may not always remain open on favorable terms.

Strategy’s expanded plan does not guarantee $64 billion of fresh capital will flow into Bitcoin. But it does clarify the firm’s intent and gives a detailed glimpse of the mechanisms it is prepared to use. For market participants, the key questions now center on execution speed, investor appetite for high-yield preferred exposure, and whether Bitcoin’s price path will validate or strain one of the most aggressive corporate treasury strategies in modern markets.
