Under the terms of the subscription agreement, KDDI will purchase 28,536,516 newly issued ordinary shares of Coincheck at a price of $2.28 per share. The transaction, totaling just over $65 million in cash, is slated to close in June 2026. Following the closure, KDDI will hold registration rights for the newly acquired shares and will be entitled to nominate one non-executive director to Coincheck Group’s board. The board appointment is expected to take place at the company’s Annual General Meeting in September 2026.

Concurrently, Coincheck’s Japanese subsidiary, Coincheck, Inc., executed a formal business alliance with KDDI. The operational partnership is designed to leverage KDDI’s extensive consumer distribution network to integrate Coincheck’s crypto trading, custody, and staking infrastructure. The companies outlined plans for mutual customer referral programs, shared revenue models, and initiatives intended to reduce friction in user onboarding for digital assets.

Coincheck Group CEO Pascal St-Jean characterized the partnership as an indicator of the ongoing convergence between traditional financial institutions and the digital asset sector, noting that the telecom’s investment validates Coincheck's regulatory and institutional infrastructure.

Representing KDDI, Shumpei Tatebayashi, Deputy General Manager of the Open Innovation Division, stated that the alliance will focus on pairing technological innovation with the safety and trust required to bring new financial services to Japanese consumers.
