ARK Invest-Backed Firm Becomes Largest ETH Hoarder Outside the US

TLDR

• Quantum Solutions has acquired 3,866 ETH worth $14.8M in less than a month
• The Tokyo-listed firm is now the largest ETH DAT outside the United States
• Quantum raised $180M to build a 100,000 ETH treasury backed by ARK Invest
• The firm is buying ETH at a pace of nearly $1M daily and plans to accelerate

Quantum Solutions, a Tokyo-listed firm backed by ARK Invest, has become the largest Ether digital asset treasury (DAT) outside the United States. The company has quickly accumulated thousands of ETH as it aims to build one of the largest ETH holdings globally. This move comes at a time when other regional markets are tightening regulations around publicly listed crypto treasuries.

Quantum Solutions Accelerates ETH Accumulation

Quantum Solutions has acquired 2,365 ETH in just seven days, worth around $9 million at current market prices. Founder Francis Zhou announced the update on Thursday, stating, “We have officially become the largest ETH DAT outside the US.” The purchase brings the firm’s total Ether holdings to 3,866 ETH, which is valued at approximately $14.8 million, based on data from its website.

The Tokyo Stock Exchange-listed company has positioned itself as Japan’s leading publicly traded Ether holder. It now ranks as the 11th largest Ether treasury in the world, according to tracking platform CoinGecko. The firm is reportedly acquiring ETH at a daily rate of 150 million yen (around $983,000) and plans to continue building its digital asset reserves.

Backed by ARK Invest and SIG

Quantum Solutions raised $180 million in September with the goal of building a 100,000 ETH treasury. The funding round was supported by major venture firms, including ARK Invest and Susquehanna International Group (SIG). This capital is being used to steadily expand its ETH holdings in the open market.

Cathie Wood, CEO of ARK Invest, confirmed support for the initiative, saying on Thursday, “Three months into the DAT revolution, we’re happy to support Japan’s first institutional-grade ETH DAT.” ARK Invest has also invested in BitMine, chaired by Tom Lee, which holds the largest Ether DAT globally. ARK added both firms’ stocks to its innovation and fintech funds in September.

Japan’s Regulatory Environment Supports DAT Growth

While Quantum Solutions is gaining ground in Japan, other regions have become less favorable to digital asset treasuries. Authorities in Hong Kong, India, and Australia have imposed stricter rules on crypto holdings by publicly listed companies. In contrast, Japan continues to allow and support such structures, making it a unique environment for firms like Quantum Solutions.

The firm’s public status also adds transparency to its ETH purchases, as these are often disclosed through regulatory filings or investor updates. This regulatory clarity is attracting more institutional interest in Japan, where crypto is still regulated under financial instruments laws rather than banned or restricted.

DAT Sector Slows but Quantum Expands

The digital asset treasury trend has seen slower momentum in recent weeks. Some of the largest crypto-holding firms have experienced a drop in share prices. Market analysts have begun to question whether the enthusiasm around DATs is declining. Tom Lee, chairman of BitMine, recently asked if the “DAT bubble” may have burst, though he continues to invest during price corrections.

Despite this cooling trend, Quantum Solutions remains focused on its long-term target of accumulating 100,000 ETH. The firm also holds a small Bitcoin treasury, totaling 11.6 BTC worth about $1.3 million. Zhou has indicated that the company will continue to accelerate its ETH purchases in the coming months.
