MicroStrategy Adds Nearly 18K Bitcoin, Boosting Corporate Treasury Dominance

• MicroStrategy buys nearly 18K BTC, showing strong confidence despite Bitcoin trading below its cost basis.
• Corporate BTC accumulation tightens supply, shifting liquidity and giving long-term holders more market influence.
• Institutional buying rises fast; 193 firms now hold over 5% of Bitcoin, reshaping market dynamics.

MicroStrategy is making headlines again after the world’s largest public Bitcoin holder added a massive 17,994 BTC to its treasury last week. The purchase, totaling $1.28 billion at an average price of $70,946 per Bitcoin, pushes the company’s reserves above 738,000 BTC.

According to a US Securities and Exchange Commission filing on Monday, this move comes as BTC traded mostly around $67,000, signaling confidence despite temporary below-cost conditions. Michael Saylor’s strategy demonstrates continued institutional commitment to Bitcoin accumulation. Moreover, the purchase represents the company’s largest acquisition since January, when it bought 22,305 BTC for $2.13 billion at an average price of $95,284.

Besides reinforcing MicroStrategy’s dominance, this purchase affects Bitcoin’s circulating supply and market liquidity. The nearly 18,000 BTC acquired equals roughly five weeks of newly mined Bitcoin, given daily BTC production of 450 coins. Hence, corporate accumulation is steadily tightening supply in circulation.

Strategy now holds about 3.7% of total BTC, which is expected to reach 20 million coins this week. Consequently, large institutional buyers like MicroStrategy, MARA, and Metaplanet are reshaping the supply-demand dynamics of Bitcoin markets.

Institutional Demand Reshapes Bitcoin Markets

Adoption by corporate entities has seen tremendous growth in recent years, especially after 2020, as many publicly traded firms have started to hold it as a treasury reserve asset. By March 2026, there are currently 193 firms that hold 1.138 million BTC, representing over 5.4% of the total supply, up from only 74 in 2024.

Further, large accumulators play a significant role in supporting this trend by moving their coins into long-term storage, away from active trading. The reduction in exchange liquidity is a natural consequence, resulting in a reduction in tradable Bitcoins.

Additionally, institutional accumulation supports the overall scarcity trend, which in turn affects price volatility. For instance, in the past, MicroStrategy was careful not to acquire coins when the price was below its cost. However, in recent times, there have been five acquisitions totaling 25,229 BTC since February 9.

“Since Feb. 9, Strategy’s average cost basis has dropped from $76,052 to $75,862,” noted SaylorTracker, highlighting careful but decisive buying. Consequently, corporate demand is gradually redefining how liquidity moves across Bitcoin markets.
