Ethereum treasuries and spot ETFs now hold over 10% of ETH supply

Institutional and corporate accumulation of Ethereum has reached a milestone, with treasury companies and spot exchange-traded funds collectively holding more than 10% of ETH's total supply.

According to data from StrategicETHReserve, the combined holdings have climbed to 12.48 million ETH, representing 10.31% of Ethereum's supply. 

Specifically, Ethereum treasury companies collectively hold around 5.66 million ETH, equivalent to 4.68% of supply. Meanwhile, spot Ethereum ETFs hold roughly 6.81 million ETH, or 5.63% of the total.

The data reflects growing confidence in Ethereum as a yield-generating asset and the continued institutionalization of its market infrastructure. The surge in ETF inflows in recent months has coincided with public companies such as BitMine and SharpLink adding ETH to their balance sheets — a trend often compared to the Bitcoin treasury movement led by Strategy.

In October, U.S. spot ether ETFs recorded $621.4 million in monthly net inflows, compared to inflows of $285.7 million in September and $3.9 billion in August, according to SoSoValue data .

On Monday, SharpLink said it has seen its unrealized profits surge past $900 million since launching its ETH treasury strategy in early June.
