Three Samsung Group subsidiaries announced Thursday that they will jointly acquire a combined 4% stake in Dunamu, the company that operates Upbit, South Korea's dominant cryptocurrency exchange. The total price is 612.8 billion won, equivalent to roughly $408 million. The deal closes June 19.

Samsung Securities is taking 2% of the company, while Samsung SDS and Samsung Card are each acquiring 1%. The shares, totaling 1.39 million, are being sold by four Kakao-affiliated entities: Kakao Investment, Kakao Ventures, Kakao Youth Entrepreneurship Fund, and the KIF-Kakao Woori Bank Technology Finance Investment Fund. The sale marks a complete exit by Kakao from Dunamu.

A Samsung official said the acquisition was "intended to strengthen each affiliate's competitiveness in digital asset-related businesses," according to The Korea Times. Each unit has a distinct strategic rationale. Samsung Securities is targeting token securities, which are blockchain-based versions of traditional financial instruments such as bonds or equity. Samsung SDS, the group's IT services arm, plans to layer its artificial intelligence, cloud computing, cybersecurity, and data management capabilities onto Dunamu's blockchain infrastructure. Samsung Card is aiming to build a digital asset payment ecosystem and, if South Korea launches won-based stablecoins, could integrate crypto payments through Monimo, Samsung Financial Networks' unified payments platform.

Upbit, which Dunamu launched in October 2017 in partnership with US exchange Bittrex, controls more than 80% of South Korean crypto trading volume and ranks among the leading spot exchanges globally by daily volume. It processes between $2 billion and $4 billion in trades per day, according to CoinGecko data. The exchange was also the first entity in South Korea to receive a Virtual Asset Service Provider (VASP) licence when regulators issued it in September 2021.

The Samsung transaction is the latest in a string of large institutional bets on Dunamu. Hana Bank acquired a 6.55% stake for roughly $670 million on May 15, with that deal set to close June 15. Hanwha Investment earlier in 2026 raised its holding to approximately 9.84%, in a transaction valued at more than $440 million. And in November 2025, Naver Financial announced an all-stock acquisition of Dunamu valued at around $10.3 billion. That merger is awaiting approval from South Korea's Fair Trade Commission and has been pushed back to September 30, 2026, from an originally expected closing date of June 30, 2026. The Samsung and Hana Bank share sales are separate block transactions that operate independently of the Naver deal.

This cluster of investments is tied directly to South Korea's regulatory shift. In January 2026, the country ended a ban on corporate crypto investment that had been in place for approximately nine years, allowing roughly 3,500 listed companies and licensed professional investors to allocate up to 5% of their equity capital annually to the top-20 cryptocurrencies by market cap on Korea's five major exchanges. The Virtual Asset User Protection Act, which came into force in July 2024, had already introduced prohibitions on market manipulation and new investor safeguards. A broader framework, the Digital Asset Basic Act (DABA), is still moving through the legislative pipeline after delays stemming from a dispute between the Financial Services Commission and the Bank of Korea over who should regulate stablecoins.

For markets outside Korea, the more consequential detail is the stablecoin infrastructure taking shape around Dunamu. Samsung Card has indicated potential crypto-payment integration through Monimo if won-based stablecoins are introduced, and Hana Bank has expressed interest in building won-pegged stablecoin infrastructure for payments and remittances. South Asia is the world's largest recipient of remittances, according to World Bank data, and Korean diaspora and trade channels could eventually support KRW-to-INR, KRW-to-BDT, or KRW-to-PKR corridors if those rails are extended regionally. In Sub-Saharan Africa, where high remittance demand and growing stablecoin appetite are reshaping cross-border payments, the 5% corporate investment cap model South Korea is testing could inform how regulators in Nigeria, Kenya, or ECOWAS member states eventually open the door to institutional participation.

The Kakao exit also carries a signal of its own. Kakao backed Dunamu from its earliest days, and its full divestiture marks the end of startup-era venture capital ownership in the company. Industrial-scale conglomerates including Samsung, Hana Bank, and Hanwha are now the buyers, reflecting a structural maturation that crypto exchanges in other emerging markets will face as their own platforms grow beyond early adopter trading volumes into regulated financial infrastructure.
