Japanese telecommunications giant KDDI has agreed to invest $65.06 million in Nasdaq-listed cryptocurrency exchange Coincheck Group (CNCK), acquiring a 14.9% ownership stake through the purchase of 28.5 million newly issued shares at $2.28 per share. The deal, expected to close in June 2026 pending regulatory approvals, values Coincheck at approximately $437 million on a post-money basis.
The strategic investment includes a comprehensive business alliance covering customer referrals, revenue sharing, and referral fees. KDDI, which boasts over 72 million mobile subscriptions as of December 2025, plans to integrate Coincheck’s trading, custody, staking, and asset-management services into its consumer channels, aiming to broaden cryptocurrency access across Japan. As part of the agreement, KDDI will receive the right to nominate one non-executive director to Coincheck Group’s board at the next AGM, expected in September 2026.
This move deepens KDDI’s existing Web3 ambitions. Since 2023, the company has launched αU, a metaverse and Web3 service featuring an NFT marketplace and crypto wallet, and formed a capital alliance with Web3 wallet developer HashPort to enable conversion of Ponta loyalty points into stablecoins and crypto, redeemable as au PAY gift cards. Coincheck, regulated by Japan’s Financial Services Agency, has rebuilt its reputation after a notorious 2018 hack that lost $530 million in NEM tokens, later going public on Nasdaq in late 2024 via a SPAC merger. The exchange also recently expanded through the acquisition of digital asset prime broker Aplo.
The investment signals growing confidence in regulated crypto platforms among non-financial corporations and underscores the convergence of telecommunications and digital assets in mainstream finance.
