Corporate Ether Holdings Surge to $13B as Price Breaks $4,300

Corporate treasuries are deepening their bet on Ethereum, with total holdings now valued at roughly $13 billion following a fresh rally in the world’s second-largest cryptocurrency.

According to data from Strategic ETH Reserve (SER), companies collectively hold 3.04 million ETH, a figure that has swelled in tandem with Ether’s climb past $4,300. The token has surged more than 20% in the past week, briefly touching $4,332 on Monday before settling near $4,290 at press time.

Big Movers Drive the Surge

Three firms, BitMine Immersion Technologies, SharpLink Gaming, and The Ether Machine, now account for more than half of the top 10 corporate ETH treasuries, holding a combined 1.7 million ETH worth over $7 billion.

BitMine Immersion Technologies saw the most dramatic growth, expanding its holdings by over 410% in the past month to 833,100 ETH. That stash, worth about $2.9 billion at $3,700 just last week, has now jumped to more than $3.58 billion, making BitMine the first company with over $3 billion in Ether on its balance sheet.
SharpLink Gaming increased its treasury by nearly 142% to 521,900 ETH. The position has risen in value from $1.91 billion to over $2.23 billion, with SER data showing more than $670 million in unrealized gains.
The Ether Machine marked Ethereum’s 10th anniversary earlier this month with a 15,000 ETH purchase, later adding another 10,600 ETH over the weekend. It now holds 345,362 ETH worth nearly $1.5 billion.

Wider Institutional Participation

While the largest players dominate the headlines, smaller acquisitions are also contributing to the total. Last Friday, Hong Kong–listed IVD Medical purchased approximately $19 million in Ether via the HashKey exchange, though the exact token amount was not disclosed.

In total, SER tracks 64 companies with Ether in their treasuries, underscoring a growing trend: corporations are not just holding Bitcoin, they are increasingly turning to Ethereum as a strategic asset.

The surge in holdings and valuations mirrors a broader shift in institutional crypto adoption, with regulated ETFs, clearer compliance frameworks, and Ethereum’s growing role in decentralized finance helping to cement its place in corporate portfolios.
