Corporate crypto focused treasuries kept adding BTC and ETH this week, with Strategy’s (NASDAQ: MSTR) bitcoin stack crossing a new threshold, Strive (NASDAQ:ASST) narrowing the gap with MARA Holdings, and Bitmine Immersion Technologies (NYSE: BMNR) pushing its ether position to 6.02 million tokens.Strategy, the Michael Saylor-led firm that remains the largest publicly traded bitcoin holder, bought 334 BTC between late September and October 4 for about $28.7 million.
The coins were acquired at an average price of roughly $85,839. The purchase, disclosed in a Monday filing with the Securities and Exchange Commission (SEC), lifted total holdings to 848,000 BTC.
That stack was acquired for about $64 billion including fees, at an average cost near $75,441 per coin, and was valued around $73 billion at recent prices, implying paper gains on the order of $9 billion.
The latest buy was funded with proceeds from sales of Class A common stock and the company’s dollar cash balance.
Strategy sold about 92,894 MSTR shares for roughly $15.7 million and covered the rest of the purchase with about $13 million in cash.
The position now represents more than 4 percent of bitcoin’s 21 million-coin supply cap.
Alongside the accumulation, the company repurchased preferred shares and used part of its dollar reserve for dividends and debt interest, ending the period with a multi-billion-dollar reserve and hundreds of millions still held as cash.Strive moved faster in absolute terms.
The firm purchased 2,000 BTC between September 28 and October 2 at an average of about $84,422, spending roughly $169 million.
It was Strive’s largest addition since a 2,500-coin buy in early June and brought holdings to 29,462 BTC, worth about $2.55 billion.
That leaves the company roughly 6,115 BTC behind MARA Holdings, which holds 35,577 BTC and currently ranks as the fourth-largest public bitcoin treasury.
Funding came mainly from sales of SATA preferred shares, which accounted for a majority of capital raised, with warrant exercises contributing tens of millions more.
The purchase puts Strive within striking distance of MARA, even as the race for the second spot grew more crowded after Japan’s Metaplanet finished the quarter near 44,000 BTC.
On the ether side, Bitmine Immersion Technologies said its combined crypto, cash, marketable securities, and other investments totaled $17.4 billion as of October 4.
The core of that figure is 6,016,414 ETH, marked at $2,726 per token, or about 4.9 percent of an estimated 122.1 million-token supply.
The company described itself as 99 percent of the way toward its “Alchemy of 5%” target after about 15 months of accumulation.
It also holds 214 bitcoin, $643 million in cash and marketable securities, a $180 million stake in Beast Industries, and a $117 million position in Eightco Holdings.
Bitmine added 15,112 ETH over the past week and said it has bought ether every week since launching the treasury strategy on June 30, 2025.
About 5.07 million ETH, or 84 percent of the balance, is staked, with annualized staking revenue projected near $363 million on a recent seven-day yield of 2.63 percent.
Chairman Tom Lee framed the quarter’s price action as evidence that ether is pulling away from traditional benchmarks.
He said ether’s outperformance of the S&P 500 by 6,832 basis points in the third quarter of 2026 was notable given a hawkish Federal Reserve, higher oil prices, rising global bond yields, and tighter financial conditions, adding that the gap was “dwarfing other macro assets.”
