Samsung Securities, Samsung SDS, and Samsung Card announced a combined 612.8 billion won (approximately $446 million) acquisition of a 4% stake in Dunamu, the company that runs Upbit, South Korea's largest cryptocurrency exchange. The deal closes June 19. Samsung Securities takes 2% while Samsung SDS and Samsung Card each take 1%. The four selling parties are Kakao-affiliated entities, including the KIF-Kakao Woori Bank Technology Finance Investment Fund, completing a full exit from positions the tech giant originally built over 13 years.

The Samsung transaction is the third major stake sale in as many weeks. Hana Bank agreed to pay roughly $670 million for a 6.55% stake closing June 15, and Hanwha Investment Securities agreed to pay approximately $433 million for a 9.8% stake, also closing June 15. The implied valuation of Dunamu across all three deals lands in a consistent range of roughly $10.2 billion to $11.15 billion. With its stake now secured, Hanwha Investment Securities becomes Dunamu's third-largest shareholder, behind founders Song Chi-hyung at 25.5% and Kim Hyeong-nyeon at 13.1%, while Hana Bank becomes the fourth-largest.

Why Korean Conglomerates Are Buying In

Each Samsung unit cited a distinct strategic rationale. Samsung Securities pointed to token securities issuance and distribution. Samsung SDS, which in early May 2026 won a government contract to build South Korea's national tokenized securities platform for the Korea Securities Depository, framed the stake as an extension of that mandate into the private sector. The KSD platform is scheduled for completion by February 2027, the same year the proposed Digital Asset Basic Act targets formal STO regulatory rails, a timeline alignment that signals coordinated institutional positioning across the two initiatives.

Samsung Card cited its Monimo consumer finance platform and the goal of building a crypto payment ecosystem, including stablecoin-ready payments.

A Samsung Group official told the Korea Herald the purchases would "strengthen each affiliate's competitiveness in digital finance and help secure leadership in the rapidly evolving digital asset market."

Dunamu said it plans to "collaborate on blockchain-based financial products, payment infrastructure, distribution systems, and AI-powered services."

The broader context matters here. South Korea lifted a nine-year ban on corporate crypto investment in January 2026, allowing listed companies and professional investors to allocate up to 5% of equity capital into the top 20 cryptocurrencies on five major domestic exchanges. That regulatory shift unlocked the institutional appetite now pouring into Dunamu. A proposed Digital Asset Basic Act, currently in legislative debate, would add formal licensing requirements, stablecoin reserve rules mandating 100% or greater reserve backing, and a tokenized securities framework by 2027.

The Remittance Angle

Samsung Card's stated stablecoin ambitions carry implications beyond Korean borders. KB Financial Group has already run a proof-of-concept using a won-pegged stablecoin for remittances to Vietnam, recording an 87% reduction in transfer fees. If Samsung Card integrates stablecoin functionality into Monimo, which serves around 10 million users, similar corridors connecting Korea to South and Southeast Asian remittance markets could expand quickly, with South Asia and Africa representing additional high-potential targets for won-stablecoin payment expansion. The outcome depends heavily on unresolved regulatory questions: the Bank of Korea insists on majority bank-controlled issuance, while the Financial Services Commission has cautioned that such a structure could stifle competition.

The Numbers Behind the Optimism

Upbit held 71.6% of South Korea's domestic crypto trading volume in the first half of 2025, per the Financial Supervisory Service, with 2026 estimates placing its share above 80%. The exchange ranks 14th globally by spot volume and has accumulated over 13.26 million registered users. For full-year 2025, Dunamu reported revenue of 1.56 trillion won (roughly $1.07 billion) and net profit of 708.8 billion won (roughly $486 million).

The first quarter of 2026 told a different story. Revenue fell 55% year over year to 235 billion won, and operating profit dropped 78% year over year to 88 billion won, as broader crypto market activity cooled. Transaction fees account for 97% of Dunamu's revenue, meaning every institutional investor in this wave is effectively betting on a recovery in trading volumes alongside unproven growth in STO and stablecoin revenue streams.

Kakao Exits With a 300x Return

Kakao's original investment in Dunamu totaled approximately 2 billion won (roughly $1.4 million at the time), made about 13 years ago. The current series of sales to Hana, Hanwha, Samsung, and others is generating a blended return of roughly 300 times that figure. Kakao is directing all proceeds into artificial intelligence, signaling a deliberate pivot away from crypto infrastructure.

What Comes Next

Dunamu is simultaneously navigating a pending acquisition by Naver Financial, which announced a $10.3 billion all-stock share swap in November 2025. That deal has been delayed from June to September 2026, with a shareholder vote scheduled for August 18 and closing targeted for September 30. A post-merger IPO, potentially on Nasdaq, has drawn analyst valuations in the range of $34 to $35 billion if stablecoin and blockchain infrastructure gains traction internationally.

Samsung, Hana, and Hanwha are all buying cash stakes in a company that will look structurally different in four months. Because the Naver acquisition is structured as an all-stock share swap, the current investors' percentage ownership could be diluted or restructured once that transaction closes, adding a layer of uncertainty to the investment thesis. How governance and strategy are shared among Naver, the Samsung trio, Hana, and Hanwha after that close remains an open question.

Adding further weight to Upbit's centrality in global crypto markets: XRP was the most-traded asset on the exchange in May 2026, a concrete illustration of South Korea's outsized pricing influence in select altcoins and a reminder of how much the platform's trading dynamics matter well beyond Korean borders.
