Institutional and corporate accumulation of Ethereum has hit a milestone. Treasury companies and spot exchange-traded funds now collectively hold 12.48 million ETH, equal to 10.31% of the network’s supply, according to StrategicETHReserve.
Treasury holders account for about 5.66 million ETH (4.68%), while spot ether ETFs hold roughly 6.81 million ETH (5.63%).
ETF demand and corporate treasuries
Spot ether ETFs have been a major driver. Inflows totaled $621.4 million in October, up from $285.7 million in September, after a record $3.9 billion in August.
The flows have coincided with a growing list of public companies adding ETH to balance sheets, including BitMine and SharpLink, a pattern often compared to the Bitcoin treasury playbook popularized by Strategy.
On Monday, SharpLink said unrealized profits from its ETH treasury strategy, launched in early June, have surpassed $900 million. For corporates, ETFs and custody providers, the combination of liquidity, staking yield, and clearer rules has made Ethereum a more practical treasury asset than in prior cycles.
Why it matters and what to watch
Crossing the 10% mark concentrates a meaningful share of supply in long-term vehicles that typically rebalance on schedule rather than react to short-term price swings.
That can stabilize flows during stress, but it also increases the market’s sensitivity to ETF subscriptions and redemptions.
Into year end, the key variables are the pace of ETF inflows, staking participation from corporate wallets, and any changes in U.S. and EU disclosure rules that govern token holdings.
If allocations broaden beyond early adopters, ETH’s held-off-exchange share could rise further, tightening liquid supply across spot and derivatives venues.
