Quantum Solutions sold 1000 $ETH for approximately $1.9 million and lost its status as Japan's largest corporate holder of Ether. The top position now belongs to the company Def Consulting. The funds raised are intended for the company to create an artificial intelligence data center.
Quantum swaps either for Nvidia GPUs
According to company documents, the transaction was recorded by the Tokyo-listed technology firm through its subsidiary GPT Pals Studio on July 30. On average, the tokens were sold for $1,903 each. Their total value was approximately 311 million yen, or $1.903 million.
The proceeds will be allocated to the company's division for building AI data center infrastructure, including GPU hardware. Targeted acquisitions include Nvidia's B300 and GB300 chips, which form the physical foundation of the AI business that Quantum has been building since June.
After the deal, Quantum now owns approximately 4,764.8 $ETH. Def Consulting holds 4,976 $ETH. This places Def among the leaders in terms of public Ether holders in Japan.
On June 16, GPT Pals already sold 904 $ETH for approximately $1.6 million. In less than two months, Quantum has sold 1,904 $ETH in two transactions. This represents about 29% of the 6,668.8 $ETH it held before the sales began, and since mid-June, its holdings have decreased by 28.6%.
Collateralized assets limit the volume of goods Quantum can still sell
Quantum accumulated the majority of its stack during the late 2025 cryptocurrency rally, when Ether traded in the range of $4,000 to $4,500. The remaining position is worth approximately $9.1 million, with $ETH trading around $1,906. The company expects to record a loss of approximately $100,000, or 17 million yen, from the latest sale. This loss will be reflected in the profit for the financial quarter ending in February 2027.
Quantum's board of directors extended the timeframe for further sales. It raised the approved ceiling from 1,875 $ETH to 4,375 $ETH. Thus, on paper, another 2,471 $ETH is available for sale until October 30.
Of the Ether remaining on the balance sheet, 3,050 $ETH is pledged as collateral for a loan previously issued to a Singapore-based lender. The GPT Pals trading account holds 1,714.8 $ETH. Therefore, there is a shortfall of more than 750 $ETH of freely sellable inventory to meet the new authorization. Quantum will need to release or exchange the pledged collateral, or purchase more Ether to reach the required amount.
Future sales depend on Ether prices and how quickly the construction of the data center depletes cash. BitMEX co-founder Arthur Hayes also reduced his stake earlier this year, selling around 6,000 $ETH at a loss as the asset traded sideways. Blockchain data at the time showed that other large holders continued to accumulate their positions.
