Samsung Securities, Samsung SDS, and Samsung Card — three financial and IT affiliates of South Korea's Samsung Group — said on May 28 they will jointly acquire a 4.0% stake in Dunamu, the parent of Korea's dominant cryptocurrency exchange Upbit, for ₩612.8 billion ($447 million). The 1.39 million shares are being purchased from Kakao affiliates, according to the disclosure reported by Asia Business Daily (Asia Economy, a Seoul-based financial newspaper) on May 28, 2026.
The allocation is split as follows:
| Acquirer | Stake | Role |
|---|---|---|
| Samsung Securities (016360.KS) | 2.0% | Samsung's brokerage arm |
| Samsung SDS (018260.KS) | 1.0% | Samsung's IT services unit |
| Samsung Card (029780.KS) | 1.0% | Samsung's consumer-credit subsidiary |
At an implied ₩440,863 per share (₩612.8 billion divided by 1.39 million shares), the price sits within ₩1,611 of the ₩439,252 appraisal-rights value tied to Dunamu's pending share swap with Naver Financial — a benchmark earlier flagged by Seoul market watchers as the likely transaction floor for any Kakao-side disposal (Bloomingbit, Jan. 16, 2026).
Why now: a 33-day window before Dunamu becomes a Naver subsidiary
The disclosure lands 33 days before the Naver Financial–Dunamu stock swap is scheduled to take effect on June 30, 2026. The swap values Dunamu at ₩15.1 trillion ($10.3 billion) and will turn Dunamu into a wholly owned subsidiary of Naver Financial, the payments arm of Naver, Korea's largest internet portal operator. Shareholders of both companies approved the swap at general meetings on May 22, 2026, with each Dunamu share converting into 2.54 newly issued Naver Financial shares (Cointelegraph; TradingView News).
In practical terms, the ₩612.8 billion outlay is therefore a purchase of pre-conversion shares in the future Naver Financial–Dunamu combined entity, not a standalone Dunamu position. The strategic rationale Samsung disclosed — Samsung Securities pursuing "token securities issuance and distribution, virtual asset services," Samsung SDS blending its IT, AI, and cloud capabilities with Dunamu's blockchain stack, and Samsung Card supporting digital-asset payment functionality "when won-denominated stablecoins are introduced" — only delivers if the Naver merger closes on schedule (Asia Business Daily, May 28).
The third Kakao-side disposal in May
This is the third major sale of Kakao-side Dunamu shares disclosed during May 2026:
| Buyer | Stake | Price | Disclosed | Completion |
|---|---|---|---|---|
| Hana Bank (one of Korea's big-four commercial banks) | 6.55% (2.28M shares) | ~₩1.0325 trillion ($670M) | May 15 | June 15, 2026 |
| Hanwha Investment Securities (Hanwha Group's brokerage) | 3.90% (1.36M shares; raising total to 9.84%) | ₩597.8 billion ($433M) | May 21 | June 15, 2026 |
| Samsung Securities + SDS + Card | 4.0% (1.39M shares) | ₩612.8 billion ($447M) | May 28 | Not specified in disclosure |
Sources: CoinDesk (Hana); Bloomingbit (Hanwha); Asia Business Daily (Samsung).
The cumulative migration of Dunamu equity from Kakao-side holders to Korean financial and IT groups during May 2026 totals roughly 14.45% on a face basis (Samsung 4.0% + Hana 6.55% + Hanwha 3.90%), drawing from multiple Kakao subsidiaries: Kakao Investment alone held 10.58% before the Hana sale and fell to 4.03% after it (Coincentral; BigGo Finance, May 15, 2026).
The won-stablecoin throughline
The won-pegged stablecoin opportunity is the common thread across all three May transactions. Hana Bank's parallel disclosure cited "won-pegged stablecoins, blockchain remittances, tokenized securities and digital asset management" as collaborative areas with Dunamu (CoinDesk). Samsung Card's framing of payment functionality "when won-denominated stablecoins are introduced" mirrors that language (Asia Business Daily).
Both sides are positioning ahead of Korea's proposed Digital Asset Basic Act, the legislative framework that would, if passed, regulate won-pegged stablecoin issuance domestically (CoinDesk). Upbit, the exchange operated by Dunamu, handles more than 80% of South Korean virtual asset trading volume (CoinDesk), giving a future Naver Financial–Dunamu entity a near-default distribution channel for any won-stablecoin product the new shareholders co-develop.
The open question
Two specific data points will determine whether the ₩612.8 billion outlay produces the optionality Samsung is paying for:
June 30, 2026 swap effectiveness. The Naver Financial–Dunamu swap requires a Fair Trade Commission (Korea's antitrust regulator) business-combination review and a major-shareholder change review under Korea's Act on the Use and Protection of Credit Information. Dissenting-shareholder appraisal-rights requests run May 22 to June 11, 2026 (Cointelegraph). A heavy appraisal-rights election could disrupt the timeline.
Won-stablecoin regulatory progression in H2 2026. Samsung Card's payment-side rationale, and Samsung Securities' tokenized-securities pitch, both presuppose that the Digital Asset Basic Act or an equivalent framework advances. Without it, the three Samsung affiliates own a passive minority position in a Naver subsidiary with limited operational integration.
The first observable confirmation will be the post-swap shareholder register at Naver Financial — specifically, whether the three Samsung affiliates appear with the converted equivalent of their 1.39 million Dunamu shares (roughly 3.53 million Naver Financial shares at the 2.54x ratio), and how that position interacts with Hana Bank's and Hanwha Investment Securities' own newly converted stakes.
