Quantum Solutions is now the biggest ETH treasury outside the United States after buying $9 million worth of Ethereum in one week. The Tokyo-listed company currently holds 3,866 ETH, making it Japan’s largest public ETH treasury and the 11th-largest in the world.
The company posted on X, stating that it purchased 2,365 ETH in seven days and plans to continue buying more to build a 100,000 ETH treasury, with assistance from ARK Invest and Susquehanna International Group.
Quantum Solutions increases ETH Holdings quickly
Quantum Solutions spent about 150 million yen (about $983,000) each day last week to buy Ethereum. The company aims to build the largest digital asset treasuries in the world, and its founder, Francis Zhou, stated that it will continue to buy ETH until it reaches its 100,000 ETH holdings.
Quantum Solutions now holds 3,866 ETH (about $14.8 million) and also has a smaller Bitcoin treasury with 11.6 BTC (nearly $1.3 million).
Cathie Wood, CEO of Ark Invest, said her company is more than happy to support Quantum Solutions’ mission. The investment management firm will fund Japan’s first institutional-grade Ethereum digital asset treasury (DAT) to continue purchasing ETH, aiming to achieve a 100,000 ETH holding.
Ark Invest will also lend the company credibility, as other investors and partners will see that a popular and well-respected global investor is backing Quantum Solutions. The investment management company also invested in BitMine earlier this year and added Quantum Solutions’ stock to its innovation and fintech-focused investment funds in September.
Favorable rules fuel Ethereum accumulation
Companies like Quantum Solutions can easily buy and hold ETH in Japan because the country has favorable rules for digital asset treasuries, unlike neighbors like Hong Kong, India, and Australia, where regulators have started making it difficult for DATs to grow.
Analysts say that fewer investors today are interested in DATs and that share prices for some of the biggest crypto holders have dropped recently. However, this hasn’t stopped Quantum Solutions from buying more coins.
Other prominent Wall Street and crypto-related firms holding substantial Ethereum positions include Sharplink Gaming, Bit Digital, Coinbase Global, and ETHZilla. Each of these firms owns at least 100,000 ETH worth hundreds of millions of dollars as of the time of writing. CoinGecko’s data shows 14 firms that hold a combined total of 4,663,201 ETH worth around $18 billion.
Ethereum (ETH) rose 2% on Thursday as large investors, or “whales,” continued to buy the dip despite mounting caution in key on-chain indicators. Throughout the week’s volatile trading, wallets holding between 10,000 and 100,000 ETH accumulated more than 200,000 ETH since Saturday, boosting their collective balance to over 22.31 million ETH as of Wednesday, according to data from CryptoQuant.
In contrast, smaller investors have been trimming their exposure. Wallets holding between 100 and 10,000 ETH collectively offloaded around 140,000 ETH during the same period.
This divergence is also reflected in exchange activity. The 7-day moving average of ETH exchange netflows has flipped from -47,000 ETH to +9,200 ETH since Saturday, indicating that more tokens are being deposited onto exchanges—often a precursor to selling—than withdrawn to private wallets.
