Key takeaways:
-
Around 70% of all ETH is held by just 10 addresses, but most belong to staking contracts, exchanges or funds, not individual whales.
-
Nearly half of all ETH sits in a single smart contract: the Beacon Deposit Contract that powers Ethereum’s proof-of-stake system.
-
Big institutions like BlackRock, Fidelity and listed companies now hold millions of ETH, turning Ether into a serious treasury asset.
-
ETH ownership has moved on from early adopters. Today, it’s all about the platforms and services building on top of it.
As of August 2025, onchain data shows that the top 10 Ether (ETH) holders control around 83.9 million ETH (about 70% of the total circulating supply).
So, the community has started asking: Who actually holds the majority of ETH? The answer points to protocol-level smart contracts, major exchanges, exchange-traded fund (ETF) trusts and even public companies.
This article explores the Ether rich list of 2025, from the Beacon staking contract and Coinbase’s hot wallets to BlackRock’s ETHA trust and Vitalik Buterin’s legendary holdings.
Top Ether addresses by balance
Ether’s circulating supply as of mid‑2025 stands at approximately 120.71 million ETH. Following the Pectra upgrade in May, issuance has stabilized near net zero. This provides the backdrop for understanding Ether ownership distribution.
As briefly explored, the top 10 Ether addresses hold 83.9 million ETH as of Aug. 4, 2025 (roughly 70% of the total supply).
Looking wider, the top 200 wallets account for over 52%, holding more than 62.76 million ETH (most of these holdings are tied to staking contracts, exchange liquidity, token bridges or custodial funds). Unlike inactive Bitcoin whale addresses, these Ether whale addresses are actively used infrastructure, which reflects ETH’s ability to adequately power staking, decentralized finance (DeFi) and institutional operations.
Who owns the most Ether in 2025?
As of Aug. 4, 2025, the Beacon Deposit Contract holds approximately 65.88 million ETH, representing about 54.58% of the total circulating supply of 120.71 million ETH.
These figures are broadly consistent with March 2025 reports, which estimated the share at around 55.6% (see figure below).
This smart contract is the entry point for Ethereum validators, each of whom must deposit at least 32 ETH to participate in securing the network.
Even after withdrawal functionality was enabled in 2023, funds aren’t instantly liquid. Validators must exit the active set, wait around 27 hours for the unbonding period and then rely on a protocol-controlled sweep to release ETH.
This makes the Beacon contract the largest ETH holder — not a person, but the network itself.
With slashing penalties and structured exits, it ensures validator accountability. Still, some critics argue that concentrating half the supply in a single contract introduces systemic risks in the event of coordinated exits or protocol-level bugs.
Did you know? The Wrapped Ether (WETH) smart contract also ranks as one of the largest ETH holders, currently holding over 2.26 million ETH (around 1.87% of the circulating supply).
The second-largest ETH wallets
As of Aug. 22, 2025, these exchanges and custodians rank among the largest ETH holders:
-
Coinbase: 4.93 million ETH (around 4.09% of supply)
-
Binance: 4.23 million ETH (around 3.51%)
-
Bitfinex: 3.28 million ETH (around 2.72%)
-
Base Network bridge: 1.71 million ETH (around 1.4%)
-
Robinhood: 1.66 million ETH (around 1.37%)
-
Upbit: 1.36 million ETH (around 1.13%).
These addresses represent a layer of active infrastructure where Ether is used for the purpose of backing exchange liquidity, staking derivatives like cbETH and bridging assets across chains.
Biggest ETH wallets in 2025
As of late July 2025, BlackRock’s iShares Ethereum Trust (ETHA) drove a major shift in institutional ETH ownership. With $9.74 billion in net inflows, ETHA now (August 2025) holds over 3 million ETH (about 2.5% of the total supply), making it one of the biggest ETH wallets of 2025.
Grayscale’s ETHE remains a key player, with 1.13 million ETH under management. Fidelity’s Ethereum Fund (FETH), launched in 2024, has reached $1.4 billion in inflows, while Bitwise is pivoting from Bitcoin-only exposure to ETH-based mandates with staking features.
Together, these institutions now control over 5 million ETH (4.4% of supply), thus changing the picture for ETH holding patterns. They represent a new class of DeFi millionaires who are regulated, ETF-based and staking-aware.
Corporate Ether whale addresses
A growing number of public companies is now following a playbook similar to Strategy’s Bitcoin (BTC) plan (but with staking) to treat ETH as a treasury asset. Examples include, but are not limited to:
-
Bitmine Immersion Technologies (NYSE: BMNR) holds more than 776,000 ETH (around $2 billion), funded by a $250-million PIPE round.
-
SharpLink Gaming (Nasdaq: SBET) has acquired around 480,000 ($1.65 billion) since June.
-
Bit Digital (Nasdaq: BTBT) holds around…
