Strategy ($MSTR) and Bitmine ($BMNR) Add to Bitcoin (BTC) and Ethereum (ETH) Holdings Amid Iran Tensions and AI Uncertainty

Corporate digital asset treasury firms kept expanding their positions even as bitcoin and the wider crypto market opened the week with a modest pullback. The buying underscores a structural trend that has persisted through 2026: publicly listed companies treating bitcoin and ether as core balance-sheet assets rather than short-term trades.

Strategy (NASDAQ: MSTR), the company chaired by Michael Saylor, disclosed that it acquired 1,665 bitcoin between September 21 and 27 at an average price of roughly $85,681, bringing its total holdings to 847,666 BTC.

The same filing showed the firm also retired about $152 million of its STRC preferred stock and held $6.02 billion in dollar assets as of September 27.

The purchases were funded through sales of common stock under an existing at-the-market program.

Bitmine Immersion Technologies (NYSE: BMNR), chaired by Tom Lee, reported a parallel move on the ether side.

The firm added 17,362 ETH last week, lifting its holdings to just over 6 million tokens—approximately 4.9 percent of circulating supply and 98 percent of the way toward its stated “Alchemy of 5 percent” target.

Combined with cash, bitcoin, and other investments, Bitmine’s total holdings now stand near $17.2 billion.
