Recent data shows the firm purchased roughly 45,000 BTC in the past 30 days, while all other treasury companies combined bought just around 1,000 BTC. That marks a near-total collapse in participation across the sector.

This shift signals a sharp change in market structure. What was once framed as a growing corporate trend now depends almost entirely on a single company.

MicroStrategy now accounts for an estimated 76% of total Bitcoin holdings among treasury firms, highlighting how concentrated the strategy has become.

At the same time, cracks are beginning to show in MicroStrategy’s own model. The company’s mNAV (multiple to net asset value) remains below 1, sitting around 0.97x.

This means the stock trades at a discount to the value of its Bitcoin holdings when accounting for dilution.

That matters because MicroStrategy’s strategy relies heavily on market confidence. When the stock trades at a premium, the company can raise capital more efficiently to buy more Bitcoin.

A discount weakens that engine and signals reduced investor appetite for the structure.

Meanwhile, MicroStrategy shares have fallen about 14% year-to-date, compared to Bitcoin’s 22% decline over the same period.

While that relative outperformance may seem positive, it reflects a more cautious interpretation. Investors still value the company’s ability to accumulate Bitcoin, but they are no longer assigning a strong premium to its model.

Taken together, the data points to a fragile setup. Bitcoin treasury demand has not expanded across corporations. Instead, it has narrowed to one dominant player.

As a result, the broader narrative of institutional adoption through corporate treasuries appears weaker than expected.

The market now relies on MicroStrategy’s continued buying activity rather than a diversified base of corporate demand.

If that dynamic changes, the impact on Bitcoin demand could be immediate and significant.
