1. Legal entity / shareholders

  • Trade name (operating company): 주식회사 두나무（Dunamu Inc.）
  • Founded: 2012-04（started as a mobile securities-information service）
  • Head-office location: 서울특별시 강남구
  • Exchange-service trade name: Upbit（업비트）（operated by Dunamu）
  • Major shareholders / capital relationships:
    • 카카오 / Kakao group: deep relationship as an early investor, via Kakao Investment / Kakao Ventures
    • 하나금융그룹 / Hana Financial Group: strategic partnership / shareholding
    • 한화투자증권 / Hanwha Investment & Securities: shareholding
    • 케이뱅크 / K-Bank: real-name-account contractual partner, with a cross-shareholding relationship（Upbit is one of K-Bank’s major shareholders, 1 ）
    • Naver relationship: ecosystem collaboration rather than a direct capital relationship（adjacency via Naver Pay / Naver Cloud, etc.）
  • IPO consideration: reports of a Nasdaq-listing study（2021–2022），later shelved. Discussion of a domestic（KOSPI）listing also continues

2. Registration / license status (Korea regime)

  • 가상자산사업자 (VASP) registration: registered with the FIU（2021-09 Korea’s Phase-1 registration class）
  • ISMS / ISMS-P certification: holds KISA’s enhanced（강화）ISMS-P（requirement for operators above the 100 억원 trading-volume threshold）
  • 실명확인 입출금 계정（real-name verified deposit/withdrawal account）: a contract with 케이뱅크（K-Bank）
    • The effectively exclusive relationship with K-Bank has long underpinned the oligopolistic share of the Korean KRW spot market
    • There were periods when Upbit’s deposits at K-Bank accounted for a substantial portion of that bank’s total deposits, and the mutual-dependence structure of the two companies has been commented on by multiple media
  • For the detailed regime, see Korea's 5 major CEX regimes compared — Upbit / Bithumb / Coinone / Korbit / GOPAX

3. Listed assets

  • KRW spot market: approx. 180+ assets
  • A BTC market（BTC-quoted）and a USDT market are also operated alongside
  • Listing review: DAXA common criteria + Upbit’s own criteria（보다 더 stricter）
  • Listings / delistings have a large impact on Korean market prices, making it the core platform that drives the so-called “김치 프리미엄”（Korea premium）

4. Scope of business

  • Spot trading（KRW / BTC / USDT 3 markets）
  • Derivatives / margin trading: not offered under Korea’s VASP regulation
  • NFT marketplace（Upbit NFT, 2021 launch）
  • Staking: limited（custodial staking, under regulatory constraints）
  • Fiat deposits: only via K-Bank real-name accounts

5. Market share / trading volume

  • Korea spot-market share: approx. 70%（overwhelming #1, far ahead of Bithumb‘s 25%）
  • 24h volume: $2–10B（linked to Korean market volatility + altcoin speculative fervor, with days ranking among the global top 5 ）
  • Customer base: centered on Korean residents, with full KYC implementation
  • Global CEX ranking: consistently top 10, the world’s largest liquidity venue for certain assets
  • Dunamu was regarded as having entered Korea’s 데카콘（decacorn）ranks by valuation in 2021–2022 , one of the largest-scale startup valuations in Korean fintech history

6. History / major events

PeriodItem
2012-04두나무 founded（developed the mobile securities-information app「증권플러스」）
2017-10-24Upbit launched（provided a large number of listed assets via an API partnership with Bittrex, sweeping the Korean market）
2017-12Amid the Korean crypto boom, achieved world-#1 位 monthly trading volume（for a short period）
2019-11An ETH outflow incident on the order of 580 億 won（unauthorized hot-wallet outflow）. Dunamu compensated the full amount with its own funds
2020Concluded the K-Bank real-name-account contract
2021-03Korea’s 특정금융정보법 took effect
2021-09Completed FIU VASP registration
2021-11Launched the NFT marketplace Upbit NFT
2022Reports of a Nasdaq-listing study → shelved
2023Participated as a co-founding member of the DAXA 자율규제 협의체（self-regulatory body）
2024-07가상자산이용자보호법 took effect; built out the user-protection regime
2024–2026Continued global expansion（Upbit Singapore / Indonesia / Thailand, etc.）
2025–2026Maintained 70% share of the Korea spot market, continuing to widen the gap over Bithumb
  • K-Bank exclusive relationship: single-point dependence on the real-name account is a long-term risk factor. On the other hand, the two companies’ cross-holding of capital underpins a relationship-stabilizing structure
  • Naver / Kakao ecosystem relationship: secures domestic Korean user access through loose collaboration with Korean IT giants
  • 하나금융 / 한화 relationship: secures channels for dealing with Korean authorities / regulation through strategic partnerships with traditional financial institutions
  • Global expansion: Upbit Singapore（2018 launch, later scaled back）, plus overseas footprints such as Upbit Indonesia / Thailand. However, the scale is small relative to the Korean parent
  • 2024 User-Protection-Act response: contributions to the user-protection fund, strengthened monitoring of unfair trading, and rebuilding of internal controls
  • IPO trend: no concrete announcement as of 2026 年. If Bithumb’s push for a KOSDAQ listing succeeds, a follow-on is possible

8. Industry positioning

Upbit maintains a position close to a de facto monopoly of the Korean CEX market, serving as the center of price determination in Korea’s altcoin market. As one of the major spot markets for important tokens such as Solana / XRP / Korean-affiliated L1（Klaytn’s successor Kaia, WEMIX, XPLA）, it is also embedded in the global liquidity layer 1 .

It is the biggest beneficiary of the oligopolistic structure formed by the structural features of the Korean market（see korea-cex-five-pillars-comparison）— ISMS-P certification + 1:1 real-name-account contracts + DAXA self-regulation — and its 70% share of Korea’s KRW spot market has been nearly unshakable since 2017 年. By comparison, the Japanese CEX market（bitFlyer / Jp Exchange SBI Vc Trade / Coincheck）sees its top firm hold only around 25–30% share, a more dispersed structure.
