Institutional Bitcoin accumulation accelerated sharply in April 2026, with corporate reserves snapping up over 64,000 BTC in a single month — one of the largest buying periods since mid-2025. According to multiple data sources, publicly traded companies and institutional reserve vehicles added a gross 64,722 BTC in April, with a net increase of approximately 57,791 BTC.
The overwhelming majority of these purchases came from Strategy, the firm led by Michael Saylor, which alone bought 56,235 BTC during the month. The buying spree was largely financed through an at-the-market (ATM) share issuance model, using STRC and MSTR stock. A standout was the STRC side, which raised $3.3 billion in financing between April 1 and May 3 — about 80% of Strategy’s total $4.1 billion in ATM funding over the same period — setting a new company record.
Separately, Bitwise’s Q1 2026 Corporate Bitcoin Adoption report showed that public firms added a net 50,351 BTC in the first quarter, pushing aggregate corporate holdings to 1.15 million BTC, or 5.47% of Bitcoin’s fixed 21 million supply. The dollar value of those holdings stood at roughly $77 billion across 187 public companies, though the portfolio value dropped 18.96% from the prior quarter as Bitcoin traded around $67,805.
Strategy maintained its position as the dominant corporate holder with 818,334 BTC as of May 2026. It is closely trailed by BlackRock’s iShares Bitcoin Trust (IBIT), which held approximately 818,147 BTC. Other significant corporate holders include XXI (43,514 BTC), Metaplanet (40,177 BTC), MARA Holdings (38,689 BTC), and Bitcoin Standard Treasury Company (30,021 BTC).
The data also highlights a growing institutional interest beyond Bitcoin. Institutional companies’ total altcoin reserves reached roughly $22 billion, with $16.2 billion in Ethereum holdings, pointing to a broader corporate adoption of digital assets. The sustained buying trend, even amid a price decline, reinforces the narrative of Bitcoin as a long-term treasury asset.
