Strategy bought 24,869 Bitcoin between May 11 and May 17, 2026. The company paid an average of $80,985 per coin, spending $2.01 billion in aggregate. Every dollar came from ATM share sales.

The May 18 8-K makes the cumulative picture plain. Strategy now holds 843,738 BTC at an average cost of $75,700 per coin, with a total acquisition cost of $63.87 billion.

The New Tranche Was Bought Above the Last Filed Fair Value

The timing creates a concrete reference point. Strategy disclosed aggregate fair market value of approximately $64.04 billion as of April 26, 2026, per the May 6 10-Q, when the per-coin price used in that valuation was $78,258. The new tranche was acquired at $80,985 per coin, above that snapshot level. The cost basis on last week's purchase is higher than the price embedded in the most recent filed fair-value figure. Whether that gap has closed or widened depends on where Bitcoin trades when Strategy next files a quarterly report.

The $21 Billion Reserve Has Not Moved Yet

The 8-K includes a disclosure that matters beyond the weekly purchase number. Strategy announced a new $21.0 billion ATM offering for $MSTR common stock on March 23, 2026, called the $MSTR Increase. That capacity has not yet been drawn. The filing states that sales under the $MSTR Increase may begin once capacity under the existing offering is substantially depleted. The existing offering is still active. When it runs dry, the $MSTR Increase becomes the next funding vehicle. That sequencing means Strategy's near-term acquisition pace is bounded by how fast the current ATM depletes, not by any capital constraint.

Net proceeds in the filing are presented after sales commissions, which is standard ATM mechanics. The filing does not specify what the proceeds will be used for beyond the disclosed Bitcoin purchases already made during the reporting period.

Filing Cadence Reflects the Strategy Model

$MSTR's Filing Risk Score sits at 100, driven by the density of capital markets disclosures the company generates. This is not a distress signal. It reflects how Strategy operates: frequent ATM activity, regular BTC update 8-Ks, and ongoing capital structure changes produce a high-intensity disclosure cadence by design. The Event Momentum score is also at the ceiling for the same reason.

The BTC Exposure Score of 85 captures what the equity actually is. Bitcoin holdings at 843,738 BTC dominate the balance sheet. The software segment is present but no longer the primary driver of how investors or analysts read the stock.

Price context adds some texture. $MSTR is up roughly 28% over the past 90 days but down about 60% from its level a year ago, sitting below its 200-day moving average while holding above its 50-day. The stock is in a short-term uptrend inside a longer-term drawdown from the mid-2025 highs. That combination reflects how tightly the equity tracks Bitcoin price direction across different time horizons.

The Macro Backdrop Is Calm but Sentiment Is Not

The broader crypto environment at the time of the filing shows a split picture. Bitcoin dominance was 58.2%, meaning Bitcoin is pulling a larger share of total crypto market capitalization than altcoins. Realized volatility over the past 30 days was approximately 25%, a relatively calm regime. But the crypto Fear and Greed index sat at 29, in fear territory. A calm volatility reading alongside a fear sentiment reading means the market is not panicking, but it is not confident either. For a company buying Bitcoin at $80,985 per coin with ATM proceeds, that sentiment backdrop is the operating environment.

The next read on this story is the next weekly 8-K. Strategy files these BTC update disclosures regularly. The number to watch is whether the existing ATM capacity runs low enough to trigger the $MSTR Increase, which would signal the pace of acquisition is accelerating faster than the current offering can support.
