Strategy bought 24,869 BTC last week. The May 18 8-K makes it official.

The purchase ran from May 11 through May 17, 2026, at an average price of $80,985 per BTC, costing $2.01 billion in aggregate. Funding came entirely from ATM equity sales. That brings aggregate holdings to 843,738 BTC, with a blended cost basis of $75,700 per BTC and a total aggregate purchase price of $63.87 billion across all acquisitions.

For context on the position's current value: Strategy disclosed aggregate fair market value of approximately $64.04 billion as of April 26, 2026, per the May 5 10-Q. The May 17 holdings figure is larger than the April 26 snapshot by 24,869 BTC, so the disclosed fair value understates the current position size.

The ATM Is Doing the Heavy Lifting

Every BTC acquired in this period came through ATM equity issuance. That is the pattern Strategy has run consistently, and this week's filing confirms it held through a purchase of more than $2 billion in a single week. The filing notes that net proceeds are presented after sales commissions, so the gross equity raised was modestly higher than the $2.01 billion acquisition cost.

The ATM capacity question matters here. On March 23, 2026, Strategy announced a new $21.0 billion $MSTR stock offering, which the filing calls the $MSTR Increase. That capacity does not activate until the existing ATM is substantially depleted. The 8-K discloses that the aggregate remaining capacity reflects both the current offering and the $MSTR Increase combined. That structure means Strategy has a deep reserve of equity issuance capacity queued behind the current program, and the transition between the two does not require a new capital markets announcement.

843,738 BTC and a Cost Basis That Still Trails the Purchase Price

The blended cost basis of $75,700 per BTC against a $80,985 average for last week's tranche shows Strategy is still adding at prices above its historical average. That gap has been narrowing as the company accumulates at higher prices. The aggregate purchase price of $63.87 billion against the April 26 fair market value of $64.04 billion (snapshot date April 26, per the 10-Q) shows the position was barely above water on a cost basis at that point. Price movement since April 26 affects that relationship, but the filed figure is the only disclosed position value available.

Filing Risk and Disclosure Cadence

$MSTR's Filing Risk Score sits at 100, driven by the density of capital markets and Bitcoin acquisition disclosures the company generates. The BTC Exposure Score is 85, anchored on the size of the Bitcoin position relative to enterprise value. Both scores reflect the same underlying reality: this company files constantly because it is constantly transacting, and the Bitcoin position is the dominant equity variable.

The elevated disclosure cadence is a feature of the strategy, not a warning about financial condition. Strategy files an 8-K every time it updates Bitcoin holdings or completes a capital markets transaction. At the current acquisition pace, that means frequent filings.

Price Context Against the Acquisition Pace

$MSTR has gained roughly 28% over the past 90 days but sits about 3% lower over the past 30 days, per cached price data as of May 20. The stock trades above its 50-day moving average but below its 20-day and 200-day moving averages. That split reflects a short-term uptrend sitting inside a longer-term drawdown from the mid-2025 highs. The 52-week high was $457.22 on July 16, 2025. The stock is roughly 60% below that level.

The crypto Fear and Greed index read 29 (fear) at the time of this filing, and Bitcoin's 30-day realized volatility was running at approximately 25% annualized, a calm regime by historical standards. That backdrop made last week's $2 billion ATM-funded purchase operationally straightforward. A higher-volatility or lower-sentiment environment would test whether the ATM can absorb that volume without meaningful price impact on $MSTR shares.

What Changes the Read

The next material disclosure to watch is the pace at which the current ATM capacity depletes. Once it is substantially exhausted, the $MSTR Increase activates and Strategy gains access to the full $21 billion reserve. The timing of that transition will appear in subsequent 8-K filings. A second watch item is whether the average purchase price per BTC continues to run above the blended cost basis, which would gradually compress the unrealized gain disclosed in quarterly fair-value accounting.
