This landmark investment was reported by ACN Newswire on September 28, 2025, highlighting its significance within the crypto and investment communities.

The investment is notable for its scale, establishing Quantum as Japan's leading Ethereum champion and making it the country's first listed ETH treasury company.

ARK Invest's first direct investment in Japan via Quantum extends its track record of backing category-leading crypto firms and enhances Quantum's global visibility.

Leading international investors, including SIG, ARK Invest, and IAM, demonstrate strong confidence in Quantum, with SIG providing capital to accelerate ETH accumulation and future fundraising.

SIG's involvement, through CVI Investments, leverages its portfolio, including early investments in ByteDance and NASDAQ-listed Strategy Inc, to support Quantum's growth.

ARK Invest, led by Cathie Wood, is making its first direct investment in APAC-listed opportunities, further bolstering Quantum's international profile.

The initiative aligns with Japan's government policies promoting blockchain growth, positioning Quantum as a pioneer in the country's crypto-linked equities market.

Quantum aims to become Japan's first ETH treasury, targeting a long-term goal of accumulating 100,000 ETH, which is viewed as a foundational asset for blockchain applications.

Quantum's CEO, Francis B. Zhou, with extensive blockchain experience, plans to leverage the funds to expand ETH holdings, supported by data showing ETH treasuries trade at higher valuation multiples than Bitcoin treasuries.

Market data from Barchart Solutions indicates ETH treasuries are valued at a high price-to-book multiple of 7.72x, over three times higher than Bitcoin treasuries, reflecting strong market expectations for ETH's long-term potential.

Quantum Solutions has announced a major strategic financing initiative, raising over JPY 26 billion (approximately USD 180 million) through innovative instruments like convertible bonds and warrants, with no discounts, signaling strong investor confidence.

This funding round, announced on September 26, 2025, involves significant institutional investors such as SIG, ARK Invest, and IAM, and aims to strengthen Quantum's position in Ethereum (ETH) strategies and the Tokyo stock market.
