Three Samsung affiliates — Samsung Securities, Samsung SDS, and Samsung Card — announced on May 28 the combined acquisition of a 4% stake in Dunamu, the operator of South Korea’s dominant crypto exchange Upbit, for approximately 612.8 billion won or $408 million — the latest in a growing wave of South Korean financial institutions racing to secure strategic positions inside the country’s most valuable digital asset company.The shares will be purchased from a group of Kakao-affiliated funds including Kakao Investment and Kakao Ventures, at a per-share price of approximately 439,250 won — a valuation implying Dunamu’s total corporate worth at approximately 15.3 trillion won, or roughly $11.1 billion, per Wu Blockchain and Korea Times. Samsung Securities will acquire a 2% stake, while Samsung SDS and Samsung Card will each take 1%, with the transaction scheduled to close June 19, per Korea Times.Three Affiliates, Three Strategic RationalesEach Samsung entity entered the deal with a distinct operational agenda, per Korea Times. Samsung Securities cited plans to strengthen cooperation on token securities issuance, distribution, and virtual asset services. Samsung SDS — the group’s IT and cloud arm — said it will combine its artificial intelligence, cybersecurity, and data management capabilities with Dunamu’s blockchain operational infrastructure.Samsung Card, the group’s payments unit, aims to build a digital asset payment ecosystem with Dunamu including potential integration with Monimo, Samsung Financial Networks’ unified financial platform, contingent on the introduction of won-based stablecoins in Korea.The three objectives — securities tokenization, blockchain infrastructure, and stablecoin-enabled payments — map directly onto the pillars of South Korea’s Digital Asset Basic Act, which is expected to be finalized in 2026, per Korea Times.A Crypto Race That Was Already UnderwaySamsung’s $408 million commitment arrives as South Korea’s institutional financial sector converges on Dunamu simultaneously. Hana Bank agreed earlier this month to purchase a 6.55% stake for approximately 1 trillion won ($670 million), per Korea Times. Hanwha Investment and Securities separately increased its Dunamu holdings to 9.84% — committing an additional 597.8 billion won — making it one of Dunamu’s largest non-founding shareholders, per Wu Blockchain.Dunamu itself recorded a net profit of 708.8 billion won on revenues of 1.56 trillion won in fiscal 2025 and handles more than 80% of South Korean virtual asset trading volume, per Korea Times.A Samsung official told Korea Times that the investment was intended to strengthen each affiliate’s competitiveness in digital asset-related businesses, adding that closer cooperation with Dunamu could help the companies secure leadership positions in Korea’s emerging digital asset market.This development marks a critical juncture for the nascent sector’s integration with Korean corporate conglomerates. A Samsung investment in a crypto exchange — even at 4% — carries symbolic weight that extends well beyond the balance sheet, signaling that South Korea’s most powerful industrial dynasty now views digital asset infrastructure as core to its financial services strategy for the decade ahead.Cover image from Grok, BTCUSD chart from Tradingview
