Historically, Bitcoin's price was driven by a mix of demand from retail investors, institutions, speculators, and ETF capital. Today, however, the capital structure of the crypto market appears to be becoming more concentrated than ever. The latest data indicates that Strategy (MSTR.US) is emerging as the most pivotal force supporting Bitcoin's price.

Currently, Bitcoin is priced at approximately $77.5K, down nearly 30% from a year ago. Despite this overall market weakness, Strategy, led by Michael Saylor, continues its large-scale Bitcoin acquisition. According to company disclosures, Strategy has purchased a cumulative total of 171,238 Bitcoins so far this year. This volume even surpasses the roughly 62,000 new Bitcoins produced by the global miner network during the same period.

Benchmark-StoneX analyst Mark Palmer noted that Strategy currently appears to account for the majority of net corporate and ETF-related Bitcoin buying expected through 2026. Research firm 10x Research stated more bluntly that if investors are still looking to Federal Reserve commentary, macroeconomic data, or ETF flows to gauge Bitcoin's direction, "they might be misreading the real trend."

Strategy primarily raises funds through a perpetual preferred stock financing instrument called STR C. This product offers investors an 11.5% annual cash dividend, and Strategy uses the proceeds to continuously purchase spot Bitcoin. Market data shows that in the past three weeks alone, Strategy accounted for about 12% of all Bitcoin trading activity, with its share exceeding 20% in some weekly trading periods.

Markus Thielen, CEO of 10x Research, believes that Bitcoin demand is increasingly reliant on "financial engineering" rather than organic market demand. Concurrently, key forces that drove the 2024 Bitcoin bull market—ETF arbitrage capital, retail investors, and long-term holding by miners—are significantly weakening.

Reports indicate that U.S. Bitcoin ETF flows have recently slowed markedly, and retail trading volumes in Asian markets like South Korea continue to decline. Furthermore, mining companies are also beginning to sell more Bitcoin to pivot towards AI data center and AI computing infrastructure businesses. This suggests the Bitcoin market is becoming increasingly dependent on a single buyer for support.

This concentration raises market concerns. If Strategy's future financing capacity diminishes or it ceases its continuous buying, Bitcoin's price could face heightened volatility risk. Strategy currently holds approximately 843,700 Bitcoins, with an average purchase cost of around $75,700—only slightly below the current market price. A further decline in Bitcoin's price would not only impact Strategy's balance sheet but could also erode market confidence in the STR C financing model, potentially creating a negative feedback loop.

Meanwhile, Strategy's management has recently hinted for the first time at the future possibility of "not ruling out the sale of some Bitcoin." Saylor even likened the company to a real estate developer, suggesting that selling some Bitcoin might be considered if it helps improve the capital structure or enhance the "Bitcoin per share value."

Nevertheless, analysts generally believe Strategy will continue its large-scale accumulation strategy in the short term. However, a growing market concern is whether the crypto asset market, now valued at around $1.5 trillion, has become overly reliant on a single buyer for support.
