MicroStrategy, the world's largest public Bitcoin holder, has once again made a massive purchase. The company acquired 17,994 BTC last week for approximately $1.28 billion, at an average price of $70,946 per coin. This move pushes its total holdings past 738,000 BTC, cementing its dominance in corporate treasury accumulation.
According to a US SEC filing on Monday, the purchase was executed while BTC traded around $67,000, below MicroStrategy's average cost. Despite the temporary below-cost condition, the company showed conviction. In January, it had bought 22,305 BTC at $95,284 each for $2.13 billion — meaning the latest buy came at a noticeably lower average price.
Cost Basis Drops to $75,862 as Buying Accelerates
The 17,994 BTC acquisition equals roughly five weeks of newly mined Bitcoin (450 coins per day), highlighting how corporate hoarding tightens circulating supply. SaylorTracker data reveals that since February 9, MicroStrategy has made five purchases totaling 25,229 BTC, bringing the company's average cost basis from $76,052 down to $75,862. “Since Feb. 9, Strategy’s average cost basis has dropped from $76,052 to $75,862,” the tracker noted, indicating deliberate accumulation at favorable levels.
Now MicroStrategy holds about 3.7% of all Bitcoin, as total supply is expected to hit 20 million coins this week. Other large players like MARA and Metaplanet are following similar strategies, collectively reshaping supply-demand dynamics.
Institutional Holdings Double: 193 Firms Hold 5.4% of Total Supply
Corporate adoption of Bitcoin as a treasury asset has surged since 2020. By March 2026, 193 publicly listed firms hold a combined 1.138 million BTC, representing 5.4% of the total supply — up from just 74 firms in 2024. These large accumulators tend to move coins into long-term storage, reducing sell-side liquidity. Exchange balances are shrinking as tradable Bitcoin becomes scarcer.
Historically, MicroStrategy avoided buying when prices dipped below its cost basis, but recent activity shows a change. Since February 9, it has made five acquisitions totaling 25,229 BTC, signaling that institutional focus on long-term scarcity now outweighs near-term price sensitivity. Corporate demand is steadily redefining how liquidity flows across Bitcoin markets.
