A fresh estimate suggests Michael Saylor's Strategy added more Bitcoin shortly after the market opened, putting BTC accumulation back in focus.

Michael Saylor’s Strategy added 6,556 Bitcoin  BTC +0.00% to its treasury in a single week, spending $555.8 million at an average price of $84,785 per coin, according to a Form 8-K filed with the U.S. Securities and Exchange Commission on April 21, 2025.

What the SEC Filing Reveals About Strategy’s Latest Purchase

The Form 8-K disclosure shows Strategy acquired the 6,556 BTC between April 14 and April 20, 2025. The purchase brought the company’s total Bitcoin holdings to 538,200 BTC, accumulated at an aggregate cost of $36.47 billion and an average price of $67,766 per coin.

Strategy funded the acquisition through its at-the-market issuance programs. The company sold 1,755,000 shares of MSTR common stock for $547.7 million and 91,213 shares of STRK preferred stock for $7.8 million to finance the buy.

The filing also noted that Strategy uses its website dashboard as a Regulation FD disclosure channel, reinforcing the company’s commitment to transparency around its Bitcoin treasury operations. At the time Cointelegraph covered the announcement, BTC was trading near $85,000.

Why the Timing Drew Immediate Attention

Initial reports framed the purchase estimate as surfacing less than an hour after U.S. market open, according to unconfirmed social media reports. That timing matters because early-session institutional activity often sets the narrative for the rest of the trading day, particularly for assets correlated with MSTR’s stock price.

Large Strategy purchases have historically amplified short-term Bitcoin sentiment. Traders tracking Bitcoin ETF inflows and corporate treasury moves treat each new filing as a signal of sustained institutional demand. The pattern reinforces a feedback loop where public accumulation announcements attract additional buyer interest.

Bitcoin was trading at $73,264 at press time, up roughly 1.26% over the prior 24 hours, with a market cap near $1.47 trillion and daily trading volume around $39.3 billion.

The Fear and Greed Index sat at 16, deep in “Extreme Fear” territory. That reading contrasts sharply with Strategy’s willingness to deploy over half a billion dollars at prices well above current spot levels.

What This Means for Strategy’s Bitcoin Accumulation Story

With 538,200 BTC on its balance sheet, Strategy remains the largest publicly traded corporate holder of Bitcoin by a wide margin. The $36.47 billion aggregate cost basis at an average of $67,766 per coin means the company is currently underwater relative to the press-time spot price of $73,264, though still above its blended average.

Each new purchase filing renews debate over corporate treasury exposure to BTC. For investors watching how broader crypto markets are positioning, Strategy’s continued accumulation during a period of extreme fear signals conviction that contrasts with prevailing retail sentiment.

The dual-ATM funding structure, using both MSTR common shares and STRK preferred shares, gives Strategy flexible capital access without taking on traditional debt for these purchases. That mechanism has allowed Saylor’s team to execute repeated large buys across varying market conditions.

Institutional accumulation trends, including developments like protocol-level revenue innovations across the broader crypto ecosystem, continue to draw attention from market participants gauging whether corporate demand can sustain Bitcoin’s price floor through periods of weak sentiment.

The next scheduled SEC filing window will reveal whether Strategy continued buying after April 20 or paused as Bitcoin moved lower in subsequent sessions.
