Key points

  • Publicly traded companies added about 5,900 BTC over the past three months, according to Glassnode data cited by CoinDesk.
  • The comparable period a year earlier brought more than 100,000 BTC of corporate accumulation, including roughly 89,000 BTC in July 2025.
  • Corporate treasuries' estimated average acquisition cost of about $80,500 was above bitcoin's reported spot price near $76,400.

Corporate accumulation loses momentum

Publicly listed companies added about 5,900 bitcoin to their balance sheets over the past three months, according to Glassnode data reported by CoinDesk on September 18. At a reported spot price near $76,400, the increase was worth roughly $451 million. The total marks a pronounced slowdown for a buyer group that supplied an important source of incremental demand during the 2024–25 market advance. It does not mean every company stopped buying, but it shows that aggregate corporate accumulation has become much less forceful.

The year-over-year comparison is stark

During the corresponding period a year earlier, public companies accumulated more than 100,000 BTC, including approximately 89,000 BTC in July 2025 alone. The latest three-month addition is therefore less than 6% of that earlier total and below 7% of July 2025's reported amount. That comparison is more informative than a single weekly purchase because it smooths out announcement timing and shows how substantially the corporate-treasury cycle has cooled. The figures remain estimates assembled from public disclosures and market data rather than a centrally reported regulatory series.

Strategy still dominates the category

The public-company sector remains highly concentrated. Bitcoin Treasuries lists roughly 1.22 million BTC across 181 public companies, while Strategy accounts for about 845,050 BTC of that total. That leaves the category sensitive to the acquisition schedule of one company. CoinDesk noted that Strategy supplied most of the recent additions, including a late-August purchase of 4,603 BTC. A quieter period for Strategy can therefore make the broader corporate total look weak even when smaller holders continue to add modest amounts.

Average cost sits above spot

Glassnode's estimate places corporate treasuries' average acquisition cost near $80,500, around 5% above the reported spot price of approximately $76,400. That gap leaves the group underwater on an aggregate cost-basis measure, although individual companies have very different entry prices, financing structures and accounting treatment. A lower market price can encourage new purchases, but it can also restrain companies that rely on equity issuance, convertible debt or a premium valuation to fund additional bitcoin. The data does not establish which consideration is driving current decisions.

Other demand gauges remain mixed

The corporate slowdown arrives alongside uneven institutional signals. CoinDesk reported that U.S. spot bitcoin exchange-traded funds had received billions of dollars since early August but remained about $1 billion short of returning to positive net flows for 2026, based on SoSoValue data. The Coinbase premium, which compares U.S. dollar pricing with offshore markets, has also been mostly negative since May apart from September 5, according to CoinGlass. Meanwhile, stablecoin supply has stayed broadly between $300 billion and $310 billion this year. None of those indicators measures demand perfectly, but together they suggest that a broad expansion in crypto liquidity has yet to take hold.

What the slowdown means

Corporate treasuries are only one part of the bitcoin market, alongside ETFs, private funds, miners, governments and individual investors. Their slower buying is therefore a constraint on marginal demand, not a forecast of price direction. The more consequential question is whether purchases remain concentrated in Strategy or broaden across other listed companies. A sustained increase across several buyers would provide stronger evidence of renewed treasury demand than one large transaction. Until that happens, the latest figures point to caution among public companies rather than a return to the accumulation pace seen in 2025.
