Strategy adds 24,869 BTC in a week and pushes its stack to 843,738

Strategy bought another 24,869 BTC last week. The purchase ran from May 11 through May 17, 2026, at an average price of $80,985 per coin, and the company funded it entirely through ATM equity sales. The 8-K filed May 18 makes that explicit: proceeds from the sale of shares under the ATM.

The stack now sits at 843,738 BTC. Cumulative average purchase price is $75,700 per coin across the full position.

The ATM Is Still the Engine

This purchase follows the same playbook Strategy has run repeatedly. Sell equity through the ATM, convert proceeds to Bitcoin, file the weekly update. The 8-K footnotes confirm net proceeds are presented after sales commissions, which is standard ATM mechanics, and that the $MSTR Stock amount available reflects aggregate remaining capacity across the current offering and the March 23 expansion.

That expansion is the more consequential disclosure sitting inside this filing. On March 23, 2026, Strategy announced a new $21.0 billion $MSTR Stock offering, labeled the $MSTR Increase. The filing states that sales under the $MSTR Increase may begin once capacity under the existing offering is substantially depleted. The company has not disclosed how much capacity remains under the current program, so the precise timing of the handoff is not yet visible. What is visible is that the company has pre-staged a large reload before the current program runs dry.

What the Stack Looks Like Against the Filed Value

Strategy disclosed aggregate fair market value of approximately $64.04 billion as of April 26, 2026, per the May 6 10-Q, at $78,258 per BTC. The 24,869 BTC added in the May 11 to May 17 window came in above that per-coin reference price, at $80,985 average. The company is still adding at prices above the April 26 snapshot level, which means the cost basis on the incremental tranche sits above the most recently filed fair value per coin.

That gap is not alarming at this scale, but it is worth tracking as the company continues to add. The cumulative average of $75,700 across 843,738 BTC remains below the April 26 snapshot price, so the aggregate position still reflects an unrealized gain relative to that disclosed fair value.

Filing Risk and Event Density

Strategy's Filing Risk Score sits at 100 and Event Momentum matches it, both reflecting the density and recency of capital markets filings the company generates. These are not distress signals. They reflect a company that files material disclosures at a pace most public companies do not approach, because the acquisition program itself generates a continuous stream of 8-Ks.

The BTC Exposure Score of 85 captures what the filing confirms: Bitcoin is the central variable in the equity story. The direct balance-sheet exposure means that Bitcoin price movement, ATM execution pace, and available offering capacity are the three levers that matter most for anyone modeling the equity.

The Crypto Tape Adds Context

Bitcoin dominance stood at 58.2% and 30-day realized volatility was running at approximately 25% annualized as of the macro snapshot captured May 21. That is a calm realized-volatility regime relative to Bitcoin's historical range. A calm tape makes ATM execution easier: lower realized volatility generally means tighter equity spreads and more predictable dilution math for the company. The crypto Fear and Greed index sat at 29, classified as fear, which creates an interesting backdrop for a company actively adding at these price levels.

$MSTR's own price context shows the stock down roughly 3% over the trailing month and up about 28% over the trailing 90 days, sitting above its 50-day moving average but below its 20-day and 200-day averages. The short-term trend is classified as an uptrend against a longer-term downtrend, a split that reflects the sharp recovery from the February 2026 lows without yet reclaiming the highs from mid-2025.

What Comes Next

The next read is the depletion pace of the current ATM program. Once Strategy signals that existing capacity is substantially depleted, the $21 billion $MSTR Increase activates. That handoff filing, whenever it comes, will set the scale of the next acquisition phase. Watch for an 8-K or prospectus supplement that references the $MSTR Increase becoming active. That document will define the next chapter of the acquisition runway.
