STRC: How Strategy's Digital Credit Reaches Bitcoin

PART 1 — THE INSTRUMENT AND THE ENGINE

Download the full report here.

STRC, Strategy's variable-rate perpetual preferred stock paying 11.5% in monthly cash dividends, has reached $10.5bn outstanding in under nine months — roughly 2.5x the largest US bank preferred and the largest tradable monthly-paying preferred listed in the US. Strategy calls STRC “digital credit”: a category of capital-markets instruments built on a Bitcoin balance sheet, which Saylor argues will sit alongside conventional fixed income for a generation of yield-seeking allocators. This analysis takes that framing at face value and tests it: how the instrument works, what funds the dividend (and what doesn't), what Q1 2026 revealed when the structure was first stressed, and what ecosystem is now building on top of it. Part 1 covers the instrument and the engine. Part 2 covers the ecosystem, the patterns, and the outlook.

A CAPITAL STACK BUILT ON BITCOIN

As of May 2026, Strategy holds approximately 843,738 BTC. On top of that asset, Strategy has deliberately created a layered capital structure to give different audiences different exposures. MSTR common equity offers leveraged price exposure. Four perpetual preferreds offer income with seniority ranks above the common. Starting in 2025, an ecosystem of wrappers, ETPs and DeFi protocols has begun layering further products on top of those preferreds. The whole structure is the practical expression of what Strategy now markets as “digital credit”: capital-markets credit instruments collateralised by, and economically tied to, Bitcoin. STRC is the first of those instruments to reach mainstream institutional scale.

The preferred stack as of May 2026. STRC is roughly four-fifths of the preferred notional and the most aggressively yielding piece of the stack. STRF (the most senior) pays contractual cumulative dividends; STRK adds optional convertibility into MSTR common; STRD is non-cumulative and the most junior of the preferreds.

Across all four preferreds the implied annual dividend bill is roughly $1.3bn. STRC alone carries about three-quarters of that. So when this analysis refers to “the dividend,” it is mostly referring to STRC.

STRC, PLAINLY

STRC is a perpetual preferred stock listed on NASDAQ. It has a stated amount of $100 per share and currently pays a variable dividend of 11.5% per annum in monthly cash, initially set at 9.00% when it priced in July 2025. Strategy may, at its sole discretion, adjust the rate on a monthly basis in 0.25% increments. The stated intention is to use those adjustments to keep STRC's market price at o​r near $100. If the price drifts below par, Strategy can raise the rate to attract buyers; if it drifts above, it can lower the rate or tap their ATM programme. The adjustment is therefore a tool, not an automatic mechanism.

Dividend cadence in plain terms. On each 15th of a month, Strategy records who holds STRC (at the record date), and will be entitled for the payment of the upcoming dividend (on the payment date). On the record date the stock goes ex-dividend, and the price drops by roughly the dividend amount (~$0.45). Over the next two weeks the STRC price typically recovers toward the stated value of $100 as new buyers come in to capture the next monthly dividend. On the payment date, the dividend is then paid in cash to whoever held the stock on the previous record date. The cycle repeats.

A design feature that matters more than the headline rate: tax treatment. For US federal income tax purposes, 100% of Strategy's preferred distributions in 2025 were classified as Return of Capital (ROC), reported in Box 3 of Form 1099-DIV rather than Box 1. ROC distributions are not immediately taxable; they reduce the holder's cost basis, deferring the tax until the position is sold (or, in some cases, indefinitely). Strategy expects ROC treatment to continue “for the foreseeable future,” explicitly mentioning a ten-year-plus horizon. For a taxable US investor, that turns the gross 11.5% into a meaningfully higher after-tax yield than a 1099-DIV Box 1 dividend at the same rate. It is a structural attribute of STRC, not a marketing claim, and it is one of the reasons demand has been so strong.

TWO ATMS, TWO FLOWS, ONE BITCOIN BALANCE SHEET

What an ATM is. An at-the-market (ATM) programme lets an issuer sell new shares in small parcels at prevailing market prices, day after day, instead of doing a single large secondary offering. The point is to issue as accretively as possible (selling only when prices are favourable) and to keep the funding rail open continuously rather than in episodic chunks. Strategy's ultimate goal across all of its capital-markets activity is to grow BTC per diluted share. The ATM is the tool. It only works if the issuance is accretive in BTC-per-share terms, which is why pricing matters so much in the discussion that follows.

The mechanism is cleaner than it first appears, and the cleanest way to see it is to keep two flows separate.

Flow 1: the STRC ATM funds Bitcoin purchases. When STRC trades at or above par, Strategy issues new STRC shares through its Omnibus Sales Agreement, an ATM facility with TD Securities, Barclays, Benchmark and other broker-dealers acting as sales agents (running the issuance, not principal trading). Proceeds from STRC ATM sales are routed almost entirely into Bitcoin. In Q1 2026 alone, ATM proceeds across all Strategy programmes totalled approximately $7.37bn, with a further $4.32bn in April through May 3. STRC issuance has financed approximately 77,000 BTC since launch.

Flow 2: the MSTR common ATM funds the preferred dividends. Strategy runs a separate MSTR common ATM programme. Proceeds from common-share issuance are channelled into a USD reserve (more on that below), which is what services the contractual preferred dividends across all four series. STRC issuance therefore does not directly dilute MSTR common. MSTR common is diluted separately to fund the dividends that STRC and the other preferreds owe. Diluted share count rose roughly 12% in four months, from ~294m at year-end 2025 to ~331m by late April 2026.

Why the distinction matters. A common misreading conflates the two flows: STRC's dividend is not paid out of STRC's own ATM proceeds. The STRC ATM buys Bitcoin; the MSTR common ATM (via the cash reserve) pays the dividend. The two are linked reciprocally — strong STRC demand widens the BTC funding rail, which raises the asset base behind the preferreds, which makes MSTR common ATM issuance more accretive — but they are operationally distinct.

A scheduled tweak: from monthly to semi-monthly payouts. In April 2026 the board opened a shareholder vote to move STRC distributions to a semi-monthly schedule. The change is not yet effective. The stated rationale is to halve the size of each ex-dividend drop and shorten the recovery window during which the STRC ATM is constrained, smoothing the rhythm at which Strategy can issue and accumulate Bitcoin. It is a small operational improvement, but a meaningful one if the vote passes.

Bitcoin generates no cash flow. So a Bitcoin treasury company paying 11.5% in monthly cash on $10.5bn of preferred stock is, mechanically, in a position that needs explaining.

At $10.5bn outstanding and 11.50% annualised, the cash obligation is ~$1.21bn per year, or ~$101m per month. That figure rises as Strategy issues more STRC; STRC's "Total Program Authorization" was originally capped at $7bn, and although a recent Certificate of Increase raised authorised preferred shares from ~70m to ~280m, effectively lifting the practical ceiling to $28.3bn.

THE ENGINE, DEFINED AND FRAMED

Throughout this analysis, “the engine” refers to the set of processes and instruments through which Strategy follows its accumulation strategy: how capital is raised across the preferred and common stacks, how that capital is deployed into Bitcoin, and how the resulting balance sheet feeds back into the conditions that make further capital raising possible. The engine is not a single number. It is the interaction between demand for STRC, equity-market valuation of MSTR, the Bitcoin balance sheet that backs both, and the issuance windows that open and close as prices move.

With that definition in place, the engine question splits in two. STRC's own engine is preferred dividend supply and demand: yield-seeking allocators buy STRC, the rate adjusts to keep the price at par, and the proceeds buy Bitcoin. That side is straightforward to read off the par-peg and the issuance pace.

The harder side to read is the engine that funds the preferred dividends. It has two numbers, and it is best measured from the perspective of an MSTR common shareholder, because they are the ones bearing the dilution.

mNAV is the premium. mNAV is MSTR's enterprise value divided by the dollar value of its Bitcoin. At 1.2x, the market pays $1.20 for every $1 of Bitcoin Strategy holds. Above 1.0x, MSTR common issuance is accretive: the cash raised exceeds the Bitcoin those new shares effectively represent, and the surplus can fund dividends or buy more BTC without leaving common holders worse off in BTC-per-share terms. Below 1.0x, MSTR common issuance is dilutive; the company would be transferring Bitcoin to the market for less than it is worth.

BTC Yield is the score. Bitcoin per diluted MSTR share, year-to-date. If BTC Yield is +9.4%, every MSTR share represents 9.4% more Bitcoin than on January 1, after all dilution. This is the metric Strategy uses to tell common holders the engine is working for them in net terms.

How the two combine. When MSTR common issues 1% more shares at an mNAV of 1.2x, the cash raised funds Bitcoin purchases (or dividend payments backed by the BTC stack) worth roughly 1.2% of the existing stack. Net BTC-per-share accretion is roughly 0.2% per turn. At an mNAV of 2.0x, the same 1% dilution funds 2.0% in Bitcoin: net accretion ~1.0%. The engine that supports the preferred dividends does not have a single speed. Its throughput is a function of the MSTR premium at the moment of issuance.

Reading the chart. The green line tracks BTC Yield, the rate at which Strategy is adding Bitcoin per share. Because it is reported year-to-date, it resets to zero every January - that's the sharp drop visible in Jan 26, not a real change in the business. The blue line tracks the mNAV premium, the multiple at which the market values Strategy relative to its Bitcoin holdings. The red dotted line marks the current mNAV at 1.22x; values above it mean MSTR can issue new shares accretively to buy more Bitcoin.

Q1 2026: THE STRESS TEST, NAMED OUT LOUD

Three pressure points. Before walking through Q1, it helps to name the three points at which the engine can bend. The first is the par-peg: if STRC sits below $100 for an extended period, the STRC ATM cannot issue at par and accumulation slows. The second is mNAV: if MSTR's premium compresses below ~1.0x, MSTR common issuance stops being accretive and management has to choose between dilution and dividend cuts. The third is the cash buffer: if issuance stalls and the reserve thins, the only remaining option is to sell Bitcoin to cover the dividend.

The Q1 2026 choke. In Q1 2026, Bitcoin fell from ~$87,000 to ~$68,000, a 23.8% drawdown. Strategy posted a $12.54bn Q1 unrealised loss. mNAV compressed below 1.0x, STRC slipped below par for stretches, and Saylor — who told Bloomberg in January 2022 that Strategy would “never” sell its Bitcoin — told analysts on the Q1 call the company would “probably sell some Bitcoin” to fund the dividend, framing it as “1 BTC sold to buy 10-20 more” once issuance reopened. It was the first time the third pressure point (Bitcoin sales) was named out loud by the issuer.

The structure held for two reasons. The first is design: STRC ATM kept selling whenever the par-peg allowed it, financing the Bitcoin purchases that supported the asset base, while the MSTR common engine stalled and the USD reserve covered the contractual dividend payments. The second is trust: investors stayed convinced of the model through the drawdown and kept demand for STRC firm at par, so the first pressure point never fully closed. Smaller Bitcoin-treasury issuers facing the same conditions would likely not have weathered the stress in the same way, and most public BTC-treasury vehicles outside Strategy now trade below the value of their own holdings. Strategy is in a unique position because it has both the asset base and the holder base to absorb a multi-quarter pause in MSTR-common issuance. Bitcoin has since recovered toward $80,000, mNAV is at 1.29x, BTC Yield at 9.4% YTD. The structure restarted; the reserve was the backup. Saylor has since clarified his position as “never be a net seller,” which leaves a small but explicit door open.

THE $1.44BN USD RESERVE

On December 1, 2025, Strategy disclosed in an 8-K that it had established a $1.44bn USD Reserve, funded with proceeds from the MSTR common ATM, to carry preferred dividends and interest. This reserve has now grown to $2.25bn. The company's stated intention is to maintain at least 12 months of coverage and to extend that to 24+ months over time. The reserve is discretionary.

This is what made the Q1 outcome possible without forced Bitcoin sales. The reserve absorbs multi-quarter windows in which mNAV-based dilution would itself be value-destructive. It also makes the apparent trade-off less binary than the “dilute common or sell Bitcoin” framing suggests: when STRC demand stays strong (the par-peg holds, STRC ATM keeps buying BTC), the asset base behind the preferreds grows even while the reserve carries the dividend. The two flows interact constructively, not just defensively.

CONCLUSION: THE DAWN OF 'DIGITAL CREDIT'

The traditional wall between fixed income and digital assets has officially breached. Through STRC, the market is witnessing the birth of a new asset class: digital credit. Far from a mere corporate experiment, this framework represents a structurally coherent, highly liquid category designed to give yield-seeking allocators access to Bitcoin's economic upside without direct asset ownership. As other issuers rush to replicate this model and regulatory filings accumulate, the naming of this category signals a major shift in capital markets. Once "digital credit" is codified into standard indices, allocation will transition from a discretionary bet into a benchmark default.

However, this sophisticated financial engine requires clear-eyed evaluation. The structural integrity of STRC rests on a single load-bearing wall: maintaining an mNAV above 1.22x. While its cash-flow mechanics rely on a circular issuance model that requires the market flywheel to stay open, its resilient design has already defended this threshold through real-world market stress. Ultimately, STRC is no longer just an isolated instrument to analyze; it is an established macro infrastructure. The foundational mechanics are now fully understood—how the broader market chooses to scale, trade, and stress-test this new credit paradigm is what comes next.

FROM THE INSTRUMENT TO THE ECOSYSTEM

Part 1 has set out the instrument itself, the two-flow engine that powers it, the stress test it passed in Q1 2026, and the design choices (USD Reserve, discretionary rate adjustments) that made the test survivable. The structurally interesting question for the next twelve months is no longer how STRC works in isolation. It is what the market builds on top of it, and what that build-out implies for Bitcoin's marginal demand, for capital-markets price formation, and for the risk surfaces introduced by the products being layered on. Part 2 maps the ecosystem in detail: who is building, what they are building, why structural complexity escalates as exposure moves into peer-to-peer composable formats, and where Strategy's digital credit category goes from here.
