Strategy bought 24,869 BTC last week and its ATM capacity is nearly gone

Strategy bought 24,869 BTC in a single week. The May 18, 2026 8-K makes the number plain: $2.01 billion spent between May 11 and May 17, all of it funded through ATM equity sales, at an average price of $80,985 per coin.

That is a meaningful acceleration. The purchase pushed aggregate holdings to 843,738 BTC at a blended average cost of $75,700. The last SEC-disclosed fair market value sits at approximately $64.04 billion as of April 26, 2026, per the May 5 10-Q, which means the position was marked at a price below the week's average purchase price. Strategy bought aggressively into a price level above its own last disclosed mark.

The ATM Is Almost Empty

The 8-K filing includes a disclosure that carries more weight than the purchase size alone. The $21.0 billion $MSTR Increase offering, announced March 23, 2026, does not activate until the existing ATM offering is substantially depleted. Strategy is close enough to that threshold that the company felt it necessary to flag the sequencing in the filing footnotes.

843,738 BTC and a Cost Basis That Still Has Room

The blended average cost of $75,700 per BTC across 843,738 coins reflects years of purchases at varying prices. The week's average of $80,985 is above that blended basis, which means recent buying is pulling the aggregate cost upward. That is the natural consequence of a strategy that keeps buying regardless of price level.

Strategy's Filing Risk Score sits at 100, driven by the density and cadence of capital markets filings the company generates. Event Momentum matches it at the ceiling. Both reflect how frequently material disclosures arrive, not a judgment on financial condition. The elevated disclosure cadence is the product of the strategy itself: each ATM sale, each BTC update, each offering amendment generates a filing.

Price Context Adds Tension

$MSTR's price is down roughly 7% over the past week and about 3% over the past month as of May 20, per cached price context. The stock sits below its 20-day and 200-day moving averages while holding above its 50-day. The short-term trend is up, the long-term trend is down, and the stock remains more than 60% below its 52-week high set in July 2025. That gap matters because the ATM program issues equity into whatever the current price is. Selling shares at current levels to buy BTC at $80,985 is a different capital allocation decision than it was when the stock was trading near its highs.

The crypto Fear and Greed index sat at 29, classified as fear, at the time of the macro snapshot. Bitcoin dominance was 58.1%, indicating a Bitcoin-led tape. Neither reading changes the mechanics of what Strategy filed, but the fear reading is a useful backdrop: Strategy accelerated purchases during a week when broader crypto sentiment was negative.

The Sequencing Question

The filing raises a question the 8-K does not answer directly. Once the existing ATM capacity is substantially depleted and the $MSTR Increase activates, will the pace of purchases hold, slow, or accelerate? The $21 billion authorization is large. Whether Strategy deploys it at the same weekly rate, or whether the cadence reflects opportunistic timing around price levels, will become visible in subsequent 8-K BTC updates.

The next concrete read is the filing that announces the $MSTR Increase has become active. That disclosure will confirm the existing offering is exhausted and set the scale of the next accumulation phase.
