Strategy filed another Bitcoin purchase update on May 18. The company bought 24,869 BTC in the seven days ending May 17, 2026, spending approximately $2.01 billion at an average price of $80,985 per coin. The funding source was ATM equity sales, the same mechanism Strategy has leaned on through most of 2026.

Aggregate holdings reached 843,738 BTC as of May 17, 2026, with a cumulative average purchase price of $75,700 per BTC, per the May 18 8-K. For context, Strategy disclosed aggregate fair market value of approximately $64.04 billion as of April 26, 2026, per the May 5 10-Q, when the per-BTC price used for that valuation was $78,258. The May 17 snapshot does not carry a new fair market value disclosure, so the April 26 figure remains the most recent SEC-filed position value.

The ATM Engine and What Comes Next

The 8-K filing makes clear that the current ATM offering is not the last tool in the kit. On March 23, 2026, Strategy announced a new $21.0 billion $MSTR Stock offering, referred to in the filing as the $MSTR Increase. That capacity cannot be drawn until the existing offering is substantially depleted. The sequencing matters: Strategy is running two stacked ATM programs, with the larger one held in reserve.

Net proceeds in the filing are presented after sales commissions, which is standard ATM mechanics. The filing does not specify any particular use of proceeds beyond the disclosed Bitcoin purchase activity for the current period.

Disclosure Cadence at the Ceiling

Strategy's Filing Risk Score sits at 100, and Event Momentum matches it. Both reflect the density of capital markets filings the company generates, not a judgment about financial health. A company that files Bitcoin purchase updates, ATM drawdown notices, and Regulation FD disclosures on a near-weekly basis will naturally carry elevated scores on both dimensions. The 8-K filed May 18 includes both Item 7.01 (Regulation FD Disclosure) and Item 8.01 (Other Events), which is the standard dual-item structure Strategy uses for these purchase announcements.

The BTC Exposure Score of 85 reflects what the filing confirms: Bitcoin acquisition is the central capital allocation activity, and ATM equity issuance is the primary funding mechanism. Those two facts together make $MSTR's equity performance tightly coupled to Bitcoin price movements in a way that few other public companies replicate.

Price Context Against the Purchase Price

$MSTR has gained roughly 26% over the past three months through May 20, 2026, but sits about 60% below its one-year-ago level, per cached price data. The stock trades below its 20-day and 200-day moving averages but above its 50-day, a split that reflects the short-term recovery off February lows without erasing the longer drawdown from the mid-2025 peak near $457.

The average purchase price on this week's tranche, $80,985 per BTC, sits above the cumulative portfolio average of $75,700. Strategy is still adding at prices above its blended cost basis, which is a consistent feature of the accumulation strategy rather than a deviation from it.

The Macro Backdrop Adds Texture

The crypto Fear and Greed index sat at 29, classified as fear, at the time of this filing. Bitcoin dominance was 58.2%, indicating the broader crypto tape is Bitcoin-led rather than altcoin-driven. Realized Bitcoin volatility over the prior 30 days was approximately 25%, a calm reading relative to historical norms. Strategy is adding aggressively into a fear-regime tape with low realized volatility, which is a different risk profile than buying into a greed-regime spike.

The next disclosure to watch is whether Strategy files another weekly purchase update before the current ATM capacity is exhausted, and whether the $MSTR Increase program gets formally activated in a subsequent 8-K. Activation of the $21 billion reserve offering would signal that the existing capacity has run down and that the accumulation pace is set to continue at scale.
