Coincheck Group announced the completion of a strategic investment by Japanese telecommunications company KDDI, which purchased newly issued shares worth approximately $65 million and acquired a 14.9% ownership stake in the digital asset platform provider.
Under the terms of the investment, KDDI received 28.5 million newly issued ordinary shares at $2.28 per share. The transaction closed following the share subscription and investment agreement signed on May 12, 2026.
As part of the arrangement, KDDI obtained registration rights for its shares and the ability to nominate one individual to serve as a non-executive director on Coincheck Group’s board at the company’s next annual general meeting, expected in September 2026.
In parallel with the investment, Coincheck Group’s Japanese subsidiary, Coincheck Inc., entered into a business alliance agreement with KDDI aimed at expanding the digital asset market in Japan. The partnership will focus on customer referral programs, revenue-sharing initiatives, and efforts to increase mainstream adoption and practical use cases for digital assets.
The companies plan to combine KDDI’s consumer reach and distribution capabilities with Coincheck’s cryptocurrency platform and product expertise to simplify onboarding and broaden access to digital assets throughout Japan.
Coincheck Group provides digital asset trade execution, custody, staking, and asset management services and is expanding beyond its leadership position in Japan into institutional services and digital asset infrastructure. KDDI serves more than 100 million customers and has expanded beyond telecommunications into businesses including AI, finance, energy, retail, and cybersecurity.
Coincheck Group was advised by J.P. Morgan as financial advisor and by De Brauw Blackstone Westbroek and Simpson Thacher & Bartlett as legal counsel.
There were no executive quotes included in the announcement.
