Ark Invest’s Cathie Wood-backed Quantum Solutions bought $20.58 million worth of Ethereum (ETH) on Saturday, ranking the firm among the top 15 public entities holding ETH.
Quantum Solutions, the Tokyo Stock Exchange-listed digital asset company, announced that it holds roughly 5,030 ETH, making it a major digital asset treasury (DAT) in Japan. DATs are companies that hold cryptocurrencies on their balance sheets for investors.
According to CoinGecko, Ethereum (ETH) now accounts for nearly 94% of Quantum Solutions’ crypto treasury, with Bitcoin making up the remainder. The company’s total crypto holdings are valued at approximately $16.6 million, reflecting a sharp increase over the past three months. The company currently sits at an unrealized loss of $4.71 million.
Ethereum (ETH) was trading at $3,092.51, up 1.5% over the last day. On Stocktwits, retail sentiment around Ethereum remained in the ‘bearish’ zone, with chatter changing from ‘low’ to ‘normal’ over the past day.
Institutional demand for Ethereum has intensified in recent weeks, led by significantly larger players. Another ARK Invest-exposed firm, BitMine Immersion Technologies (BMNR), on Saturday added more than $259 million worth of ETH to Ethereum’s staking system. This pushed BitMine’s total staked balance above 540,000 ETH, valued at more than $1.6 billion, according to on-chain firm Lookonchain.
The surge helped drive Ethereum’s validator entry queue close to 977,000 ETH, extending activation wait times for new validators to nearly 17 days, according to Ethereum Validator Queue.
The network data shows that more than 35.5 million ETH, or roughly 29% of total supply, is now staked, while exit activity remains comparatively limited. More ETH is being staked than withdrawn, reinforcing Ethereum’s role as a yield-generating asset for institutions rather than a short-term trade.
