Strategy just crossed 843,000 BTC. The May 18 8-K makes it official.

The company acquired 24,869 BTC in the seven days ending May 17, spending approximately $2.01 billion at an average price of $80,985 per coin. The purchases were funded through proceeds from ATM share sales under the existing $MSTR equity offering. That is the same mechanism Strategy has used for every recent acquisition: sell equity, buy Bitcoin, file the 8-K.

The Holdings Number That Matters

Aggregate holdings now sit at 843,738 BTC, acquired at a total cost of $63.87 billion and an average purchase price of $75,700 per BTC. For position-value context, Strategy's most recent SEC-disclosed fair market value was approximately $64.04 billion as of April 26, 2026, per the May 5 10-Q. That snapshot predates this week's purchase, so the disclosed figure does not yet reflect the full 843,738 BTC stack.

The gap between the average cost basis of $75,700 and the $80,985 average paid last week tells a directional story about acquisition pace: Strategy is still adding at prices above its portfolio average, which compresses the blended cost advantage over time. Whether that matters depends entirely on where Bitcoin trades over the holding period, but the arithmetic is worth tracking.

The $21 Billion Reserve Sitting Idle

The 8-K includes a detail that deserves more attention than the headline BTC number. On March 23, 2026, Strategy announced a new $21.0 billion offering of $MSTR stock, labeled the $MSTR Increase. That capacity cannot be deployed until the existing ATM offering is substantially depleted. The filing does not disclose the remaining balance of the current facility, so the precise trigger point is not public. What is clear is that Strategy has staged a second, larger reload behind the current one.

That structure means the capital markets engine has more runway than the current ATM balance alone implies. When the existing offering runs low, the $MSTR Increase activates. The acquisition pace does not have to pause for a new capital markets transaction.

Disclosure Cadence Drives the Scores

$MSTR'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. Strategy files 8-Ks at a pace that few public companies match, because each weekly Bitcoin purchase triggers a Regulation FD disclosure and an Other Events item. The elevated disclosure cadence is a feature of the strategy, not a warning sign.

Insider Activity at 50 is the one dimension where $MSTR looks like a median public company. No unusual cluster is driving that reading.

Price Context Around the Filing

$MSTR has gained roughly 28% over the past 90 days but sits about 3% lower over the past month, trading below its 20-day moving average while holding above its 50-day. The stock is down approximately 60% from its level a year ago. Sawse analytical market-activity data showed a move of roughly 2% in the session following the filing, within normal range for a weekly BTC update. The crypto Fear and Greed index registered 29 at the time of the filing, a fear reading, while Bitcoin's 30-day realized volatility was running at approximately 25.5% annualized, a calm regime by recent standards.

The combination of a fear-regime sentiment backdrop and calm realized volatility is the environment in which Strategy is deploying ATM proceeds. Whether that timing proves advantageous depends on Bitcoin's path from here, which the filing does not address and neither does this article.

What Changes the Read

The next meaningful disclosure is the depletion notice for the existing ATM facility, which would trigger the $MSTR Increase and signal how quickly Strategy is burning through current capacity. A follow-on 8-K showing another large weekly purchase at prices above $80,000 would confirm the pace is holding. A pause or a smaller acquisition would be the first sign that ATM capacity is tightening or that management is adjusting the cadence.
