Between March 9 and March 15, Strategy acquired 22,337 BTC for approximately $1.57 billion at an average of $70,194 per coin, ranking as the company's fifth-largest buying window to date, according to a Form 8-K filed on March 16.

Total holdings now stand at 761,068 BTC, more than 3.5% of Bitcoin's fixed supply. The cost basis is roughly $57.6 billion, or about $75,696 per coin on average. At current prices, the position is worth approximately $56 billion an unrealized loss of about $1.6 billion, per GN Crypto.

The stock closed at $139.67 on March 13, up 3.5% for the week even as it remains 69% below its all-time highs. Bitcoin rose about 8% over the same period, GN Crypto reported. Six weeks earlier, MSTR shed 17% in a single week when Bitcoin pulled back 25%, according to Finterra analysis via Wedbush.

The mechanism is not complicated, but the math matters.

If MSTR trades at a 50% premium to the per-share value of its Bitcoin holdings, issuing new shares at that valuation raises capital that buys spot Bitcoin at market price while existing shareholders are diluted by only their proportional share of the Bitcoin already held. When the premium exists, each new share sale can increase the Bitcoin-per-diluted-share ratio for everyone who was already in. When the premium compresses to zero or inverts, the math runs the other way: selling stock to buy Bitcoin at those terms destroys value for existing holders. The premium is not incidental to the strategy; it is the strategy, as Finterra analysis via Wedbush noted in February.

The March purchase ran two channels simultaneously. Strategy sold approximately 2.83 million common shares for about $396 million, and issued roughly 11.82 million STRC variable-rate preferred shares for approximately $1.18 billion, with around $1.96 billion of STRC capacity still remaining. STRC-driven accumulation ran 281% above the four-week average in the week before filing, per GN Crypto. No single instrument carries the full load; the model runs parallel channels targeting different investor types.

Those channels sit within Strategy's "42/42 Plan," an $84 billion capital-raising framework split equally between equity and fixed-income instruments through 2027, according to GN Crypto. As of a June 2025 SEC presentation, the overall plan was 36% complete, with the equity bucket roughly 44% deployed. Remaining authorized ATM capacity included $18.6 billion for MSTR common shares, $20.97 billion for STRK convertible preferred, and additional programs for STRF, STRC, and STRD instruments (SEC FWP, June 2025; SEC 8-K, April 2025).

That runway is narrowing faster than the 2027 end date implies. In Q1 2025 alone, Strategy deployed $7.66 billion across all four channels to purchase 80,715 BTC, per SEC filings.

The fixed-income side of the structure was deliberately built to minimize cash burden. Strategy's weighted average fixed rate across its convertible notes is 0.421% annually, with maturities extending to 2032, per the June 2025 SEC presentation. In Q4 2024, the company raised $15.09 billion through ATM equity sales and $2.97 billion through zero-coupon convertible notes due 2029, generating substantial Bitcoin purchasing capacity with minimal interest obligations, according to SEC filings.

Common stock buyers are not valuing MSTR as a software company. Market behavior and company filings indicate they are primarily buying amplified Bitcoin exposure. Because the stock has historically traded at a premium to its underlying Bitcoin-per-share value, MSTR delivers more upside than a spot ETF in a rising Bitcoin market and more downside when Bitcoin falls. From the day before Strategy's first Bitcoin purchase in August 2020 through early January 2025, the stock climbed from $12.36 to $339.66, per SEC filings. Spot Bitcoin ETPs launched in January 2024 with $4.6 billion in first-day trading volume, but that has not eliminated MSTR demand, the same filing notes. For buyers who want used Bitcoin exposure without a derivatives account, the stock still serves a purpose.

Preferred stock buyers are a different audience. They want income, and Strategy's growing preferred family STRK, STRF, STRC, and STRD targets institutional investors seeking fixed or variable dividends. Company materials presented in June 2025 claimed that at then-current Bitcoin prices, the Bitcoin stack provided approximately 290 years of preferred dividend coverage, and that even a 75% Bitcoin price collapse would leave 37 years of coverage intact, per the SEC FWP filing. Those figures come from company investor materials and should be read as such. Still, the performance record to date has attracted buyers: STRK gained 29% from its launch price and STRF gained 22% by mid-2025, outperforming the broader preferred stock market over the same window, per the same presentation.

The preferred instruments also serve a structural function that common equity cannot: they raise capital without diluting common shareholders' claims. STRD specifically was pitched as a way to access high-yield markets without touching the common stock ATM, per the June 2025 SEC filing. The tradeoff is that preferred dividends create real recurring obligations some cumulative, meaning missed payments accrue while common stock dilution does not.

Management's answer to the dilution question is a KPI called "BTC Yield," defined in SEC filings as the period-over-period percentage change in the ratio of Bitcoin holdings to fully diluted shares outstanding. Strategy explicitly discloses that this is not yield in any conventional financial sense, per SEC filings. Full-year 2024 BTC Yield was 74.3%; 2025 delivered 22.8% (SEC 8-K, January 2025; Finterra analysis via Wedbush). By that measure, the dilutive issuance grew Bitcoin per diluted share in both years.

But BTC Yield tells you nothing about whether the premium funding the mechanism is still intact, or whether the Bitcoin accumulated was worth what was paid. It measures accretion; it does not validate the economics underpinning the purchases.

Between January and July 2025, Strategy issued over 20 million Class A common shares, 5 million STRK preferred shares, and 4 million STRF preferred shares. The STRC IPO alone reduced pre-IPO ownership percentages by more than 15%, per AInvest reporting from August 2025. Whether that dilution was worthwhile depends entirely on whether the securities were issued at prices that kept BTC per diluted share growing which returns to the premium question.

Signal 1: Premium-to-NAV. This is the governing metric. If MSTR trades at or below the per-share value of its Bitcoin holdings, new common-stock issuance stops being accretive. ATM programs lose their economic justification. A sustained discount to NAV would be the clearest signal that the accumulation machine has stalled. Check this number against live market data before drawing conclusions it is the single most important data point for assessing the strategy's current status.

Signal 2: ATM issuance pace and gaps. The pace of weekly and monthly issuance is publicly observable through SEC filings. The April 2025 example is worth noting: between March 31 and April 6, 2025, Strategy made no purchases and sold no securities at all, per SEC filings. That particular pause may have been tactical. But sustained slowdowns in common or preferred ATM usage measured against the four-week averages already being tracked in the market would signal either thinning buyer appetite or deteriorating issuance economics.

Signal 3: Preferred obligations versus the cash buffer. The convertible debt side carries almost no cash cost, at 0.421% weighted average fixed interest, per SEC filings. The preferred stock family is a different kind of obligation. Strategy held approximately $8.2 billion in convertible debt and a $2.25 billion cash buffer designed to cover interest through 2028, per Finterra analysis via Wedbush. But preferred dividends some of them cumulative grow as issuance expands. If the cash buffer narrows while ATM markets tighten, preferred dividend coverage shifts from theoretical to actual constraint.

Signal 4: Remaining 42/42 Plan runway versus deployment pace. The plan targets $84 billion through 2027. At Q1 2025's deployment rate of $7.66 billion per quarter, per SEC filings, authorized capacity could be substantially consumed well ahead of schedule. The question is not whether Strategy runs out of authorization it is whether the investor base absorbing each new instrument class continues doing so on terms that keep issuance accretive. Analyst Bitcoin price forecasts in company materials averaged $225,000 for 2026, per the June 2025 SEC presentation those are company-curated projections, not independent estimates, and a prolonged Bitcoin downturn would put the entire bull case under pressure.

Strategy is no longer a software company that owns Bitcoin. It is a capital-markets structure that converts investor demand across common equity, convertible notes, and a growing family of preferred instruments into Bitcoin at scale. The software business with subscription revenue up 62% year-over-year but total software revenue essentially flat at $123 million for the quarter, per Finterra analysis via Wedbush is secondary to the financing operation.

The Q4 2025 net loss of $12.4 billion and the Q1 2025 unrealized digital-asset loss of $5.91 billion now flowing directly through the income statement under the FASB accounting standard adopted January 1, 2025 demonstrate that conventional earnings are the wrong frame for evaluating this company, per SEC filings. BTC Yield of 74.3% in 2024 and 22.8% in 2025 demonstrates that the dilutive issuance grew Bitcoin per diluted share in both years. Neither number answers the underlying question.

With 761,068 BTC representing more than 3.5% of all Bitcoin that will ever exist, per GN Crypto, Strategy is the dominant case study in corporate Bitcoin treasury construction. The next observable test is the current NAV premium. If Strategy can still issue above NAV, the mechanism runs and BTC Yield is a meaningful performance metric. If it cannot, BTC Yield stops mattering because the funding loop that generates it has closed. Watch the next ATM filings.
