Founder Francis Zhou confirmed the milestone in an October 23 post on X, stating, “We have accumulated 2,365 ETH in just seven days, officially making Quantum Solutions the largest ETH DAT outside the US.” Zhou added that the company plans to continue expanding its ETH reserves in the coming months.
Strategic expansion and institutional backing
According to Quantum’s press release, the latest acquisition was executed through its Hong Kong subsidiary on October 21. The move cements the firm’s position as the 11th largest ETH DAT globally and the top-ranked in Japan, based on data from CoinGecko.
The company’s growing treasury is supported by a recent funding round led by major institutional players, including ARK Invest, Susquehanna International Group (via CVI Investments), and Integrated Asset Management of Hong Kong. The investment marks ARK Invest’s first direct entry into Asia’s public markets.
“Three months into the DAT revolution, we’re happy to support Japan’s first institutional-grade ETH DAT,”
said ARK Invest CEO Cathie Wood, commenting on the development.
Expanding beyond ethereum
Quantum Solutions’ growing digital asset treasury follows its July announcement of a Bitcoin accumulation plan targeting 3,000 BTC over 12 months. Currently, the firm holds 1.6 BTC, valued at around $1.3 million.
With Ethereum now taking center stage in its balance sheet strategy, Quantum Solutions continues to position itself as a leading institutional player in Asia’s evolving digital asset ecosystem.
Quantum’s ETH buildup follows a strategic partnership with digital asset firm TDX Strategies to operationalize its Bitcoin Treasury program, marking a major shift from planning to full-scale execution.
