MicroStrategy’s Latest Bitcoin Buy Is Its Smallest of 2026, and the Slowdown May Be Structural

MicroStrategy bought just 535 Bitcoin (BTC) between May 5 and May 11, its smallest weekly purchase of 2026 and the latest data point in a clear deceleration of corporate accumulation.

The $43 million transaction lifted total holdings to 818,869 BTC at a blended cost of $75,540 per coin. BTC Yield, the firm’s per-share Bitcoin growth metric, stalled near 9.4% year-to-date despite continued buying.

A Clear Deceleration in Weekly Buys

The trajectory has bent sharply over four weeks. Strategy bought 34,164 BTC for the week ending April 20. That dropped to 3,273 BTC the next week, then paused entirely before Q1 2026 earnings on May 5. This week’s 535 BTC purchase confirms a return to buying, at a fraction of recent pace.

Across all purchases, the firm’s blended cost basis now sits at approximately $75,543 per coin, with cumulative spending reaching $61.86 billion.

BTC Yield reached 5.6% year-to-date in mid-April. It then jumped to 9.5% after the April mega-buy, but has since edged down to 9.4%.

Smaller purchases no longer outrun equity dilution from ongoing ATM offerings and $STRC preferred stock issuance.

That math, not Bitcoin’s spot price, now governs how aggressive MicroStrategy can be each week.

From Accumulation to Active Management

During the May 5 earnings call, CEO Phong Le and Saylor disclosed specific conditions under which they would sell Bitcoin for the first time. The criteria include funding $STRC dividends and tax management, when sales beat issuing new equity.

Shares dropped roughly 3% after the comments, reflecting the symbolic break from Saylor’s prior absolute stance against selling.

We’ll probably sell some Bitcoin to fund a dividend just to inoculate the market and send the message that we did it,” Michael Saylor, via Strategy earnings remarks.

Paired with this week’s small buy, the disclosure points to a transition from one-directional accumulation toward active balance-sheet management.

Executives still expect to be net buyers, targeting 10 to 20 BTC bought per coin sold.

The signals to watch in coming weeks are whether purchases recover, whether the company executes its first tactical sale, and how $STRC issuance evolves alongside its growing dividend obligations.
