MicroStrategy Holds $531 Billion in Bitcoin but Faces $17.1 Billion in Annual Interest Obligations

Author: Chain Research Society

As of June 3, 2026, MicroStrategy (MSTR) holds 843,706 bitcoins (with a market value of approximately $53.1 billion), while carrying $6.7 billion in convertible debt and $15.5 billion in perpetual preferred shares, resulting in annualized interest obligations of approximately $1.712 billion. Just the STRC preferred share alone amounts to $10.5 billion, with annualized dividend payments of about $1.2 billion, while the company’s software business generates annual revenue of only around $500 million—leaving barely enough to cover interest expenses.

I. The golden body's protection has been broken

From May 26 to 31, 2026, MicroStrategy sold 32 bitcoins at an average price of $77,135 per coin, totaling approximately $2.5 million. This transaction represented only 0.004% of its total holdings of 843,738 bitcoins, prompting the market to price in the risk of MicroStrategy’s cash flow collapse.

After the news broke, Bitcoin fell below $70,000 within 24 hours and is currently at $63,000; MSTR's stock price has dropped 17% over the past two days. On Polymarket, the probability of MicroStrategy selling more Bitcoin before the end of 2026 has surged to approximately 90%, as the company is forced to sell Bitcoin to cover interest payments amid dwindling cash flow.

$2.5 million is negligible for a company with a $44 billion market cap. But Michael Saylor’s repeated three-year pledge to never sell Bitcoin has been broken.

Saylor had already hinted at this during the Q1 earnings call on May 5. His exact words were: "We may sell some Bitcoin to pay dividends, with the aim of desensitizing the market and sending a clear signal that we are indeed doing so." CEO Phong Le put it more bluntly: the company will sell Bitcoin when it makes sense for them, rather than simply sitting idle saying, "We'll never sell."

Saying this indicates that MicroStrategy's own financial situation is already in grave danger.

II. The Full Picture of Debt: How Much Does MicroStrategy Owe?

MicroStrategy’s capital structure can be simplified into three layers: the bottom layer consists of 843,706 bitcoins held as reserves (asset side); the middle layer comprises convertible bonds (traditional debt); and the top layer is perpetual preferred stock (new financing layer).

2.1 Convertible Bond Structure: A Low-Interest Debt Matrix of RMB 8.2 Billion → RMB 6.7 Billion

MicroStrategy accumulated approximately $42.6 billion in convertible debt prior to 2024 (as of Q3 2024), followed by the issuance of $3 billion in 0% convertible notes maturing in 2029 in November 2024, and an additional $2 billion in 0% convertible notes maturing in 2030 in Q1 2026. At its peak, the total convertible debt amounted to approximately $92.6 billion.

On May 15, 2026, MicroStrategy used approximately $1.38 billion in cash to repurchase $1.5 billion in face value of its 0% convertible notes due 2029 at an 8% discount. After the repurchase, the total convertible note outstanding decreased to approximately $6.754 billion (Source: strategy.com Dashboard).

The current details for each batch of convertible bonds are as follows:

This batch of convertible bonds shares several common characteristics: they are all unsecured senior debt, with Bitcoin never used as collateral; the coupon rates are extremely low, with a weighted average of only 0.42%; holders have the right to convert the bonds into MSTR common shares at a predetermined price, while MicroStrategy holds the option to settle in cash, shares, or a combination thereof; most tranches include a holder put option (Put Option), a mechanism that will be explained later as a way to deflate bubbles.

It is the safest layer of the entire debt structure—not for creditors, but for MicroStrategy. The extremely low interest cost means only about $34.6 million in annual interest payments are required, while the principal repayment burden is spread out across the timeline from 2027 to 2032, with a $1 billion payment due in February 2027.

2.2 Perpetual Preferred Shares: $15.5 billion in perpetual loans

Starting in January 2025, MicroStrategy launched a new financing pathway: perpetual preferred stock. As of June 3, 2026, the total size of preferred stock had reached an impressive $15.482 billion (source: strategy.com Dashboard), 2.3 times the size of its convertible bonds.

There are currently five publicly traded series of preferred shares:

Among the five preferred shares, STRC is not only the largest in scale but also the core source of conflict within the entire debt structure.

2.3 Annualized Interest Payment Data

MicroStrategy’s software business generates annual revenue of only about $500 million, while the annual dividend on a single share of STRC preferred stock is nearly $1 billion—enough to consume all of MicroStrategy’s cash flow, which is why they are forced to sell their bitcoins.

III. STRC: How does the $8.5 billion perpetual loan work?

3.1 Product Design Logic

STRC stands for Series A Perpetual Stretch Preferred Stock, listed in July 2025, raising $2.521 billion in its IPO with an initial monthly dividend yield of 9%. Thaler refers to it as the company’s “iPhone moment,” with its core selling point being the ability to significantly expand holdings without selling a single bitcoin.

The legal nature of STRC is perpetual preferred stock, not a bond. This means:

• No maturity date: Investors can never require MicroStrategy to repay the principal. STRC carries no principal repayment pressure.

• No mandatory redemption clause: The company retains the right to redeem at $101, but this is optional, not obligatory.

• Dividends are not guaranteed: If the company decides to suspend dividend payments, the dividend blocker clause will simultaneously freeze distributions to all subordinate shares (including MSTR common shares) until STRC has made up the missed dividends.

• Not backed by Bitcoin: The official statement clearly indicates that preferred shares such as STRC are not secured by the company’s Bitcoin holdings and have priority claims only on residual assets.

In short: Buyers of STRC hand over their money to MicroStrategy and can never recover their principal; they can only exit by selling on the secondary market or, if the company chooses to redeem, at $101 per share. MicroStrategy essentially uses the capital raised from retail and institutional investors—funds that do not require principal repayment—to purchase more Bitcoin and repay maturing debts.

The current face value of STRC is only $94, a level it also reached in February this year.

Buyers of STRC are not crypto-native Bitcoin believers, but fixed-income investors seeking stable, high-yield returns. They are not investing in spot BTC, but in high-yield bonds. What they want is the 11.5% monthly cash flow, not appreciation in BTC’s price.

3.2 Three-Legged Cycle

STRC does not rely on operating cash flow; it operates in a circular loop of relying on itself:

Leg One: New investors purchase STRC, with funds flowing into MicroStrategy's account.

Second leg: Split the funds—most into Bitcoin (increasing BTC reserves), a small portion into USD reserves.

Third leg: Dollar reserves pay STRC dividends monthly; Bitcoin reserves appreciate on the secondary market.

As long as this cycle keeps running, MicroStrategy won’t need to sell any bitcoins from its holdings to pay interest.

3.3 Critical value of 2.3%

Saylor provided a key threshold calculation during the earnings call: as long as Bitcoin’s annualized appreciation rate reaches 2.3%, the annual dollar value growth of the BTC position equals or exceeds the $1.5 billion annual obligation total.

Recalculated using data as of June 3, 2026: 843,706 BTC × $63,409 × 2.3% ≈ $1.23 billion, which is lower than the current annualized obligation of $1.712 billion. At current price levels, BTC would need a higher annualized appreciation rate to fully cover all obligations. Considering the price drop from approximately $81,000 in March to around $63,000 in June (a 22% decline), the debt pressure is evident.

3.4 Timeline from Interest Accrual to Coin Sale Declaration

By mapping out the timeline from STRC's listing to the sell-coin announcement, a clear signal chain emerges:

• July 2025: STRC listing with an initial dividend yield of 9%

• December 2025: MicroStrategy quietly establishes a $1.44 billion reserve (preparing for the cessation of STRC token issuance)

• March 2026: The STRC dividend yield is increased from 9% to 11.5% (a signal of higher yield demands in the secondary market)

• April 17, 2026: Change to semi-monthly dividends (to reduce dividend date volatility)

• May 5, 2026: Celer officially acknowledges the possibility of selling BTC to pay dividends.

In nine months, STRC went from an iPhone moment to a dividend burden.

Four Exit Mechanisms for MicroStrategy's Debts

MicroStrategy’s debt strategy leverages the high premium of its MSTR stock and its preferred stock financing capacity to address principal and interest payments on its debt. For these obligations, the Seyler team primarily manages them through four key approaches.

4.1 Path One: Debt-to-Equity Conversion (The Core Exit Mechanism)

These are the underlying terms for all of MicroStrategy's convertible bonds. According to the indenture, upon maturity or conversion triggered by the holders, MicroStrategy has the option to settle in full cash, full MSTR common stock, or a combination of cash and stock.

In practice, as long as MSTR’s stock price exceeds the conversion price set at the time of bond issuance, creditors typically choose to convert their bonds into shares (since selling the shares yields a higher return than receiving cash repayment). This means that, as long as market sentiment remains optimistic, these debts will ultimately not require repayment in actual cash—they will be absorbed by the liquidity of the secondary stock market, at the cost of modest dilution of existing equity. This is precisely why MicroStrategy’s convertible bonds were so heavily oversubscribed previously.

4.2 Path Two: Cash Discount Buyback (Bursting the Bubble)

When bonds trade at a discount in the secondary market, MicroStrategy directly uses cash to repurchase the debt early.

Latest case (May 15, 2026): MicroStrategy used approximately $1.38 billion in cash to directly repurchase $1.5 billion face value of 0% convertible notes due in 2029 at an 8% discount. The conversion price of these bonds was $672.40 per share, significantly higher than the then-current MSTR stock price, rendering the conversion option nearly worthless and causing the bonds to trade at a market price of $88.93 per $100 face value. By repurchasing the bonds at a price slightly above market value, MicroStrategy not only reduced its future debt repayment burden but also recorded an immediate book gain.

To support this operation, MicroStrategy established a dedicated U.S. dollar reserve to manage liquidity. The reserve was initially set at $1.44 billion when established in December 2025, peaked at approximately $2.21 billion by the end of Q1, and then dropped sharply to about $900 million following the May repurchase (as of the June 3 dashboard data, it stands at $900 million).

4.3 Path Three: Rolling Over Debt and Debt Restructuring

During the low-interest rate window, MicroStrategy issues new bonds with larger sizes and longer maturities to redeem older bonds that are nearing maturity or subject to restrictive terms.

Classic Case (September 2024): MicroStrategy issued $1.01 billion in 2028 convertible notes (coupon rate of 0.625%), and immediately used the proceeds to redeem $500 million in senior secured notes. This refinancing move achieved two key outcomes: first, it extended the maturity profile (pushing out the repayment date); second, and most importantly, it freed up 69,080 bitcoins that had been pledged as collateral for the old bonds, returning all bitcoins to the company as unencumbered, high-quality assets.

4.4 Path Four: Transition to Perpetual Preferred Shares (ATM Offering)

This is the most obvious strategic shift by MicroStrategy in 2025–2026. To avoid the risk of a concentrated debt maturity wall from convertible bonds, MicroStrategy aggressively issued two products through its ATM program last year: MSTR (digital equity) and STRC (digital credit/preferrred stock).

The key advantage of perpetual preferred shares like STRC is that they have no maturity date and thus no principal repayment obligation. MicroStrategy is effectively using funds raised from retail and institutional investors—funds that don’t require principal repayment—to pay off traditional debt with fixed maturity dates, which carries high interest costs.

Since 2026, the preferred stock STRC alone has raised approximately $5.58 billion through ATM offerings, bringing the total amount to around $8.5 billion. A significant portion of these funds has been used to purchase Bitcoin and replenish U.S. dollar reserves.

Five: Why MicroStrategy Triggers Selling Bitcoin to Pay Interest

5.1 Trigger Chain

STRC has set up the option of selling coins to pay interest; the complete triggering chain is:

STRC issuance halted → Dollar reserves depleted → BTC must be sold to fulfill obligations before reserves are exhausted

In its daily operations, MicroStrategy pays approximately $125 million per month in dividends and interest (equivalent to an annual obligation of $1.5–1.7 billion). This amount is funded through two sources:

• 1. Funds raised from the new issuance of STRC. Investors purchase STRC, with a portion of the funds directly entering the operating account, sufficient to cover monthly payouts. This is the standard approach.

• 2. $2.25 billion in U.S. dollar reserves. When the STRC issuance rate slows and monthly fundraising falls below monthly obligations, the shortfall is covered from the reserves.

Based on current reserves of $900 million divided by monthly obligations of $125 million, coverage is approximately 7.2 months. This reflects the reduced coverage capacity compared to the previously stated 18 months, as the $1.4 billion buyback in May consumed a large portion of the reserves.

5.2 How many coins do you want to sell?

If STRC cannot be sold at all, the USD reserves are exhausted, and the price of BTC stops rising, how many BTC from MicroStrategy’s position of 843,706 BTC would need to be sold to cover annual obligations?

Formula: Annual interest payment in USD ÷ BTC price = Quantity to sell

Based on an annual obligation of $17.12 billion and a current BTC price of $63,409, approximately 27,000 BTC need to be sold annually, representing about 3.2% of the total position.

If BTC rebounds to $81,000 (the early May level), the annual selling requirement decreases to approximately 21,100 coins (2.5% of the total position).

At $63,409, and without accounting for BTC appreciation, the entire position can sustain approximately 31 years—this is how the number "BTC Dividend Coverage Years = 31.2" on the strategy.com Dashboard is derived.

5.3 Why Is Market Desensitization Necessary?

Saylor said on the May 5th earnings call that de-sensitizing the market wasn’t an offhand remark. Recently, he sold 32 coins (0.004% of the total position) to signal to the market that nothing collapsed, so future sales would cause less panic. Instead, the market crashed dramatically!

CEO Phong Le described the purpose of selling Bitcoin as strengthening the balance sheet and increasing BTC per share; MicroStrategy’s actions signify that selling Bitcoin has been redefined from a crisis-era safety net to a routine operational tool.

Six: Scenario Analysis: Could MicroStrategy Collapse?

6.1 Ponzi Scheme?

Wall Street renowned short seller Peter Schiff has repeatedly publicly called MicroStrategy a classic centralized Ponzi scheme, described STRC as an unsustainable scam, and predicted the company is on the verge of bankruptcy.

Conclusion: The judgment of a Ponzi scheme lacks data support. However, it must also be noted that MicroStrategy is not a value investment. It is a leveraged exposure instrument to Bitcoin with a premium; an mNAV of 1.23 means the stock trades at a 23% premium to Bitcoin’s net asset value, not at a price below its intrinsic value.

6.2 Real Risk Ranking (from highest to lowest)

⚠️ Risk 1: mNAV Premium Disappears → Funding Capacity Dries Up

This is MicroStrategy's most critical risk: without collateralizing its Bitcoin holdings, MicroStrategy now finds it extremely difficult to raise funds.

MicroStrategy's core financing logic leverages the premium of MSTR's stock price over BTC's net asset value by issuing shares or preferred stock to arbitrage. As long as mNAV > 1, the company receives more cash in equivalent BTC value for each share of MSTR or unit of STRC issued. If mNAV falls below 1 (i.e., the stock price drops below the value of the BTC held per share), this arbitrage mechanism ceases to function.

The current mNAV is 1.23, having narrowed significantly from the earlier range of 1.5–2.0. If it continues to converge toward 1, STRC’s ATM financing will become unsustainable, dollar reserves cannot be replenished, and the sell-coin pathway will ultimately be triggered.

⚠️ Risk 2: BTC remains stagnant for an extended period + STRC cannot be sold → Forced selling cycle

This is a vicious cycle of positive feedback and the worst-case scenario for current market expectations.

• BTC doesn't rise → New STRC buyers hold off (don't want to take on depreciating assets)

• STRC isn't selling → USD reserves continue to be drained

• Reserves depleted → Forced to sell BTC to pay interest

• Sell BTC → depress BTC price, further weakening STRC's appeal

• Loop back to step one

At the current rate of consumption of the $900 million reserve (~$125 million per month), the reserve can sustain operations for approximately seven months. This means that if the issuance of STRC remains stagnant, early 2027 will be a critical tipping point, with cash reserves depleted.

⚠️ Risk Three: Deferred Preferred Dividends → Collapse of Market Confidence

The prospectus for STRD explicitly states that dividends are non-cumulative, meaning the company may suspend payments at any time without obligation to make up missed dividends. Although STRC’s dividends are not explicitly labeled as non-cumulative, they fall under the board’s discretionary authority. Legally, MicroStrategy could suspend all preferred stock dividends.

However, suspending dividends comes at an extremely high cost: it would immediately trigger a repricing of all series of preferred shares, destroy STRC’s positioning as a savings account alternative, and effectively dismantle the entire preferred share financing program.

6.3 What risks are not present? Will Bitcoin be liquidated?

❌ Forced liquidation risk: MicroStrategy's convertible bonds are all unsecured debt, and Bitcoin has never been used as collateral. A sharp drop in Bitcoin's price will not trigger the forced sale of reserved Bitcoin. Rumors of liquidation in early June 2026 have been officially clarified as routine balance sheet adjustments.

❌ Risk of Default on Maturing Debt: The $1.05 billion convertible bond maturing in February 2027 is the most recent tranche. At that time, MicroStrategy has several options: repaying in cash, issuing new debt to refinance, or encouraging bondholders to convert to equity. With $900 million in cash reserves and ongoing preferred stock financing, a technical default is unlikely in the short term.

❌ Interest expenses crush the income statement: The annual interest on convertible bonds is only $34.6 million, which is negligible compared to the company's $44 billion market cap. The real burden lies in preferred stock dividends ($1.712 billion), but these dividends are deferred and not a contractual obligation.

From February 2027 to September 2028, MicroStrategy faces a concentrated period of bond redemptions, with over $5.9 billion in convertible bonds due for repurchase or maturity within a 12-month window; repaying the principal is the primary challenge.

Seven: What happens to Bitcoin if the worst-case scenario occurs?

7.1 Bitcoin will not be subject to forced liquidation

First, it is essential to clarify one fact: MicroStrategy’s holdings of 843,706 bitcoins have never been used as collateral for any debt. All convertible bonds are unsecured obligations, and preferred shares are purely equity instruments. This means:

• No creditor has the right to force MicroStrategy to sell its Bitcoin to repay debt, regardless of how low the price of Bitcoin falls.

• Even if MicroStrategy enters bankruptcy proceedings (an extremely unlikely scenario), Bitcoin would be distributed to creditors as a corporate asset during liquidation and would not be sold on the market.

7.2 Estimation of Selling Pressure Under Worst-Case Scenario

Even if MicroStrategy is forced to sell coins to pay interest (due to STRC being unsellable and reserves being depleted), the amount that needs to be sold is far lower than what market panic might suggest:

• Annual sales required: Approximately 27,000 BTC/year at $63,409/BTC

• Percentage of total position: 3.2%

• Daily average sell requirement: approximately 74 BTC

• Comparison: Bitcoin's average daily trading volume typically ranges from 200,000 to 500,000 BTC.

This means that, in the worst-case scenario, MicroStrategy’s coin selling would have a marginal market impact of approximately 0.02% to 0.04% of daily trading volume—insufficient to trigger a systemic sell-off.

7.3 The real market impact lies not in selling pressure, but in confidence.

The sale of 32 BTC in early June 2026 ($2.5 million) caused BTC to drop from approximately $73,000 to $63,000 within 48 hours, wiping out about $60 billion in market capitalization—24,000 times the actual sale amount.

The real pricing factor in the market is the possibility that MicroStrategy might sell; the most valuable story is the one of never selling—and now, just 32 bitcoins have shattered it.

Eight: MicroStrategy did not betray Bitcoin; it simply finally acknowledged that Bitcoin comes with costs.

If the story of MicroStrategy from 2020 to 2024 could be summed up in one sentence, it’s a software company that decided to convert all its cash into Bitcoin. But the story from 2025 to 2026 is entirely different.

MicroStrategy is no longer just a simple HODL machine. What it is doing is essentially no different from banking—transforming Bitcoin, the underlying asset, into financial products with varying risk-return profiles and selling them to different types of capital:

• MSTR common stock → Sold to equity investors seeking directional leverage exposure to BTC

• STRK (convertible preferred shares) → Sold to hedge funds seeking downside protection combined with upside participation

• STRF/STRD (High-Yield Preferred Shares) → Sell to fixed-income investors seeking high returns

• STRC (Dynamic Rate Preferred Shares) → Sold to stability capital seeking a "savings account alternative"

• Convertible bonds → Sold to institutions engaged in volatility arbitrage

Saler aims to establish a private Bitcoin bank with Bitcoin as the underlying reserve, the U.S. stock market as the funding entry point, and preferred shares as a vehicle to deliver yield products to the fixed-income market.

The premise of this machine:

• BTC has long-term upward growth (at least an annualized return of 2-3% covering dividends).

• mNAV maintains a premium (preserving arbitrage opportunities and funding capacity)

• The preferred stock market remains open (STRC is sellable).

If all three conditions hold true, Saylor may have truly transformed a software company into Berkshire Hathaway of the digital age. But if any one condition fails—especially if the mNAV premium disappears—the story quickly returns to reality.

Short-term assessment (second half of 2026): No risk of default. The $900 million cash reserve can cover approximately seven months of interest obligations, and the 31-year BTC coverage provides substantial buffer. The key monitoring window is 2027; if the nNAV premium remains below 1.1 and STRC issuance stagnates, MicroStrategy will be forced to shift from a net buyer to a net seller.

Long-term assessment: It’s playing a sophisticated, public, asset-backed credit leverage game. It has real Bitcoin assets (843,706 BTC), genuine software business revenue (~$500 million annually), and proven fundraising capability ($11.7 billion raised by 2026). But its vulnerability lies in the same place—it’s highly sensitive to market sentiment and financing premiums, which evaporate faster than Bitcoin’s price during bear markets.
