STRC In-Depth Analysis: How Strategy Builds a Bitcoin Financing Cycle Using Perpetual Preferred Shares

A unique structural phenomenon has emerged in the crypto market in 2026: the ex-dividend date of a Nasdaq-listed company’s preferred stock is becoming an unmissable date on Bitcoin traders’ calendars. Behind this phenomenon is a financial product called STRC.

According to K33 Research analysis, Strategy (formerly MicroStrategy) uses STRC perpetual preferred stock to fund routine Bitcoin purchases in mid-month, driving the company to complete its largest number of additional buys in 2026 so far. In March, STRC funded the purchase of 22,131 BTC; in April, it funded 46,872 BTC. During certain statistical periods, the scale of Bitcoin acquisitions driven by STRC has approached or even exceeded the net inflow of some U.S. spot Bitcoin ETFs during the same period.

As of May 18, 2026, Bitcoin’s latest price was $77,021.1, down 1.06% in 24 hours, up 11.76% over the past 30 days. Strategy’s total holdings have reached 818,869 BTC, forming a key force within Bitcoin’s approximately $1.54 trillion market cap. The company’s average cost basis is $75,540.

However, the significance of STRC goes far beyond a financing tool. It essentially marks a deeper shift: Bitcoin is beginning to evolve from a “purchased asset” to an “underlying asset supporting long-term credit structures.”

Overview of STRC

STRC is a Series A variable-rate perpetual preferred stock launched by Strategy in July 2025, traded on Nasdaq under the ticker STRC. Its core parameters are as follows:

• Face value: $100
• Dividend type: Floating rate, paid monthly in cash
• Current annualized dividend yield: 11.5%
• Dividend adjustment mechanism: Can be adjusted within ±0.25 percentage points monthly
• Perpetual structure: No maturity date, no redemption obligation, holders cannot demand redemption
• Non-convertible: STRC cannot be converted into MSTR common stock

Since its launch, this product has rapidly expanded its fundraising scale. The company’s Q1 financial report disclosed that STRC’s asset management reached $8.5 billion within nine months, making it the largest preferred stock globally by market value. Year-to-date, Strategy has raised $5.58 billion via STRC, a growth rate of 189%. Recent strong market reactions have further pushed STRC’s market cap to about $8.5 billion.

In terms of price performance, STRC’s Sharpe ratio is 2.53, with a volatility of about 3%, exhibiting typical fixed-income product characteristics. Q1 financials show an average daily trading volume of $375 million, with the market viewing it as a low-volatility, high-yield, highly liquid fixed-income product. Its core reason is that the product design achieves the seemingly contradictory features of “high dividend yield” and “low volatility.”

From Orange Dots to Perpetual Financing Engine

Intergenerational Shift in Financing Structure

Strategy’s Bitcoin purchase funding has gone through three clear phases.

First phase (August 2020 to late 2023): A leverage trial-and-error period. The company mainly increased holdings through convertible bonds and common stock issuance, with convertible bond coupons as low as 0.625% to 2.25%, resulting in extremely low financing costs.

Second phase (2024 to mid-2025): An acceleration expansion period. Approval of Bitcoin spot ETFs brought structural liquidity improvements to the market, with MSTR’s stock premium over Bitcoin net asset value (mNAV) exceeding 100%, creating significant arbitrage opportunities for financed Bitcoin purchases.

Third phase (from late 2025 to now): The era of perpetual equity financing led by STRC. On March 23, 2026, Strategy announced a new ATM issuance plan totaling $42 billion—$21 billion allocated to MSTR common stock, $21 billion to STRC preferred stock, and an additional $2.1 billion STRK preferred stock plan. CEO Phong Le explicitly stated that the company is shifting from reliance on common stock issuance to using preferred stocks as the main financing tool for Bitcoin purchases.

Data & Structural Analysis: Dissecting the Capital Cycle Mechanism

Core mechanism: a three-step cycle

The logic behind STRC-driven Bitcoin purchases can be summarized as a three-step cycle.

Step 1: Demand anchoring. STRC offers a floating annual dividend yield of 11.5%, paid monthly in cash. This yield can be adjusted within ±0.25 percentage points monthly based on market conditions, keeping STRC’s trading price near its $100 face value. When the market price approaches or reaches face value, institutional investors, seeking high-yield fixed cash flows, generate buying demand.

Step 2: ATM issuance trigger. When STRC’s price reaches or exceeds $100 per share, Strategy issues new STRC shares via the ATM plan. This mechanism allows the company to gradually sell shares directly in the open market without underwritten offerings each time.

Step 3: Funds converted into BTC. Strategy uses the proceeds from STRC issuance directly to buy Bitcoin in the market, completing the “equity capital → Bitcoin asset” transformation.

The uniqueness of this cycle lies in the tight temporal coupling between STRC’s financing and Bitcoin’s purchase. K33’s research reveals a rhythm: the dividend qualification date is usually around the 15th of each month. To qualify for dividends, investors tend to buy STRC before ex-dividend date, pushing its price above face value, activating ATM issuance, and ultimately concentrating Bitcoin buying in the middle of the month. On the eve of the May 15 ex-dividend date, STRC’s single-day trading volume hit a record $1.53 billion, over four times the average of the past 30 days, with many trades at or above $100 face value, providing direct evidence of this rhythm.

Structural safety design: “Dividend Blocker”

A key feature in STRC’s design is the “Dividend Blocker.” If STRC’s dividend is missed, until all overdue dividends are fully paid, subordinate securities (including other preferred stocks and MSTR common stock) are barred from receiving any dividends. This design places STRC holders just below debt in the capital structure, effectively using Bitcoin holdings as implicit collateral, creating a hybrid product with both equity and debt priority attributes.

Quantitative comparison of financing efficiency

The core difference between STRC and common stock financing is dilution effect. STRC issuance does not affect the number of MSTR common shares, avoiding dilution of NAV per share. Meanwhile, it is estimated that every $1 of STRC raised, combined with $2 of MSTR equity financing, can leverage approximately $3 of Bitcoin purchasing power, creating roughly a 3x leverage effect.

Based on current data: Strategy’s annual dividend obligation is about $1.49 billion. If the $21 billion STRC plan is fully executed, at an 11.5% yield, Strategy would incur about $2.4 billion in annual dividend obligations. This is a fixed cash outflow, unaffected by Bitcoin price fluctuations.

As of May 2026, Strategy’s balance sheet shows about $2.25 billion in cash reserves. The company discloses that this reserve can cover over 2.5 years of dividends and interest payments. Regarding Bitcoin holdings, the annual dividend obligation accounts for only about 0.18% of the total Bitcoin assets, indicating a very high coverage multiple.

Public Opinion Perspectives: Four-Sided Discourse

Regarding STRC and Strategy’s overall model, four distinct viewpoints have formed.

Optimists: “Perpetual Bitcoin Absorption Device”

Michael Saylor describes STRC as a “never-ending Bitcoin absorption device.” The core logic is that as long as Bitcoin’s long-term return exceeds STRC’s overall financing costs, the system can theoretically operate continuously.

In recent interviews, Saylor elaborated: in his envisioned financing cycle, even if some BTC are sold in the future to pay dividends, the company could continue expanding its net holdings through new financing. He cites Bitcoin’s liquidity (Saylor mentioned daily liquidity of $20–50 billion), describing potential sell-offs as “almost unpredictable.” Note that this liquidity figure is from management’s verbal statement, with no independent third-party verification. This narrative attempts to reframe selling as “market liquidity testing” rather than “strategic shift.”

Institutional support includes Citigroup holding a position of about $138 million in Strategy, repeatedly reaffirming a buy rating. Although Citi lowered its target price from $325 to $260 on March 18, it still maintains a buy recommendation.

Skeptics: Concerns over “Ponzi-like Risks”

Market commentators like Coffeezilla question STRC, SATA, and similar enterprise preferred stock products, raising “Ponzi-like risk” concerns. The core argument is that multiple Bitcoin-holding companies are cross-subscribing each other’s preferred stocks. For example, Strive used $50 million (about one-third of its treasury) to buy Strategy’s STRC preferred stock, while issuing its own high-yield (13%) preferred stock SATA. The concern is that a Bitcoin-holding company is using a third of its cash to buy another company’s preferred stock, with both relying ultimately on the same underlying asset—Bitcoin—creating layered credit commitments.

Strive’s Chief Risk Officer Jeff Walton publicly defended STRC as a “high-quality credit product with risk-return advantages over traditional fixed income,” engaging in a 90-minute debate.

Veteran investor Peter Schiff also publicly criticized the STRC model, arguing that investors chasing the roughly 11.5% annualized yield are shifting funds from Bitcoin itself to this product.

The core question: when each layer promises double-digit returns, and all interest payments depend on the same underlying—Bitcoin’s price not falling persistently—does this multi-layered credit structure pose systemic risks?

Neutral Analysis: K33’s Rhythm Model

K33 Research’s stance leans toward structural analysis. Lead researcher Vetle Lunde notes that STRC’s ex-dividend mechanism is becoming a key driver of Bitcoin’s mid-month price movements. Investors buy STRC before ex-dividend dates to qualify for dividends, pushing its price above face value, activating ATM issuance, and increasing Bitcoin market inflows.

However, K33 also signals a noteworthy trend: since May 2026, the pace at which STRC’s price returns above face value has slowed, suggesting market demand may be approaching a plateau. This provides a critical data point for assessing the sustainability of the STRC model—the financing engine is not infinitely powerful.

Narrative Shift in Market Discourse

A deeper impact is on the narrative level. “Never selling Bitcoin” was once Strategy’s core identity differentiating it from other listed companies. On May 5, 2026, during the Q1 earnings call, Saylor tentatively loosened this stance, suggesting the company might sell some Bitcoin to pay dividends, aiming to “gradually get the market used to it and send a clear signal: we will do this.”

Saylor later clarified that this is not a strategic shift but an attempt to “vaccinate the shorts.” Regardless of intent, this statement already modifies the five-year core narrative. Market data from Polymarket shows that as of May 18, 2026, the probability of Strategy selling Bitcoin before December 31 is 85%. Benzinga reports a 79% probability of sale before June 30, and 92% before year-end.

Industry Impact Analysis

Impact 1: Bitcoin shifting from an asset to a credit underpinning

The most profound significance of STRC is not just providing a new financing channel for corporate Bitcoin purchases. It marks a deeper structural change: Bitcoin is beginning to evolve from a “purchased reserve asset” to an “underlying asset supporting long-term credit structures.”

This shift manifests on multiple levels. In capital structure, Bitcoin holdings become implicit collateral for preferred stock interest commitments, tying a listed company’s credit expansion capacity to its Bitcoin exposure. In fixed income, STRC’s 11.5% yield offers investors a return source that, while not directly from Bitcoin, is deeply dependent on Bitcoin’s price. In financialization, Bitcoin is no longer just passively held but actively integrated into corporate capital structure design, playing a role similar to collateral in traditional finance.

This transformation relies on Strategy holding over 818,869 BTC, transparent disclosure of holdings, and ongoing regulatory reporting—forming the minimum trust foundation for Bitcoin as a bottom-layer asset in credit markets.

Impact 2: Structural reshaping of corporate Bitcoin purchases

The STRC model elevates corporate Bitcoin buying from “self-funded” to “credit market-driven.” Traditionally, companies buy Bitcoin using cash on their balance sheets or through equity dilution. STRC opens a fixed-income funding pipeline—preferred stock investors seeking 11.5% annual yield indirectly channel billions of dollars into Bitcoin markets.

Since early 2026, the Bitcoin purchase volume driven by STRC has been significant, surpassing the net purchase of about 8,000 BTC by U.S. spot ETFs during the same period. This comparison reveals that corporate structured financing channels can, under certain conditions, outperform passive products like ETFs in raising Bitcoin.

However, a parallel concern is that corporate Bitcoin holdings are now highly concentrated in Strategy. Saylor disclosed on May 17 that Strategy holds about 76% of the company’s Bitcoin treasury, with other corporate holdings dropping from a peak of 95% to around 2%. This indicates that the previously promoted “broadening institutional holdings” trend has effectively become a high-concentration risk for a single company.

Impact 3: Changes in Bitcoin market supply and demand

Placing Strategy’s purchase volume in the context of total network supply helps understand its scale. The daily new Bitcoin issuance is about 450 BTC. K33 estimates Strategy’s monthly purchase at roughly 36,137 BTC, about 2.7 times the total new Bitcoin mined in a month. This means that one company’s monthly buying volume is roughly equivalent to 80 days of total miner output.

STRC institutionalizes this demand—forming a regular buy rhythm around ex-dividend dates, providing cyclical demand support. But it also creates a structural risk: if STRC financing slows or halts, this demand disappears, and market supply-demand balance will need to recalibrate.

Impact 4: Emergence of a crypto corporate credit network

An important trend is the cross-subscription among leading Bitcoin-holding companies, building a “digital capital loop” outside traditional banking.

Strive used $50 million (about one-third of its treasury) to buy Strategy’s STRC preferred stock, while issuing its own high-yield (13%) preferred stock SATA. This milestone indicates that Bitcoin-holding firms are no longer just competing over Bitcoin prices but are beginning to leverage each other’s credit tools to optimize their balance sheets.

Saylor also revealed that several DeFi platforms (including Pendle and Saturn) are tokenizing dividend exposure linked to STRC, enabling on-chain trading. He believes this trend could spawn digital banking products offering Bitcoin collateralized yields. From an evolutionary perspective, STRC is not just a financing tool but could become a bridge linking traditional credit markets with crypto-native finance.

Impact 5: Expansion of institutional capital entry pathways

Citi has accumulated about $138 million in Strategy, reflecting recognition from traditional financial institutions. JPMorgan estimates that if Strategy maintains its current growth rate, total Bitcoin purchases in 2026 could reach $30 billion.

More fundamentally, STRC offers a pathway for institutions constrained by regulation—such as pension funds, insurers, and bank trusts—to gain indirect exposure to Bitcoin. By holding a Nasdaq-listed preferred stock product, they can legally access high yields linked indirectly to Bitcoin prices. If sustainable, this could lead to more similar structured products, further broadening institutional access to crypto markets.

Conclusion

STRC is not merely a financing tool. It represents a financial experiment that elevates Bitcoin from a “reserve asset” to a “credit market underlying asset.”

Its true structural significance lies not just in enabling companies to buy more Bitcoin, but in demonstrating, on a large, regulated, and transparent scale, that Bitcoin can serve as the underlying asset supporting long-term credit—beginning to underpin fixed-income repayment commitments, entering corporate capital structures, and fostering credit expansion and collateral cycles.

The sustainability of this experiment depends on three observable structural parameters: whether Bitcoin’s long-term price trend can cover the preferred stock’s financing costs; whether demand for STRC in credit markets can continue to grow beyond phase-specific “interest rate chasing”; and whether the company has sufficient tools and flexibility to manage potential mismatches between financing and purchase cycles without triggering forced asset sales.
