South Korea's Bithumb plans a 2028 IPO after a costly error and governance overhaul, but a 54% drop in trading volume and Upbit dominance pose risks.
South Korean cryptocurrency exchange Bithumb has published a three-stage roadmap targeting an initial public offering in 2028, putting concrete dates behind a listing plan that has shifted repeatedly.
The company will spend 2026 upgrading its governance structure and converting its financial reporting to K-IFRS, the accounting standard used by publicly traded firms in South Korea. A preliminary listing review is planned for 2027, followed by an IPO attempt in 2028.
Bithumb had previously targeted a 2025 listing. Executives later acknowledged the exchange needed stronger internal controls and a more mature compliance framework before going public. Chief Financial Officer Jeong Sang-gyun said in March that accounting policies and governance had to improve first. The company has hired Samjong KPMG through the end of 2027 to guide the process.
The urgency behind those changes became clear after a costly internal mistake in February. During a promotional campaign, an employee mistakenly credited customers with roughly 620,000 bitcoin instead of a much smaller amount denominated in Korean won. The error remained largely on Bithumb’s internal ledger, but it exposed weaknesses in approval procedures and operational safeguards.
Bithumb recovered about 99.7% of the erroneous balances, absorbed the remaining loss from its own reserves, and later created a customer protection fund. South Korea’s Financial Supervisory Service examined the exchange’s internal controls and risk management practices after the incident.
Financially, Bithumb enters the IPO process from a position of relative strength. The exchange reported 2025 revenue of 651.3 billion won – roughly $430 million to $450 million – up 31.2% from the prior year. Operating profit climbed 22.3% to 163.5 billion won, though net profit fell because of valuation losses tied to crypto assets held on its balance sheet.
Bithumb added 1.74 million new users after switching its banking partner to KB Kookmin Bank, pushing market share above 30% during 2025.
The broader trading environment has become less favorable. Combined trading volume across South Korea’s five largest won-based cryptocurrency exchanges dropped 54.6% in the first half of 2026. Bithumb’s market share eased from roughly 30.7% to around 27% during parts of the year as Upbit continued to dominate.
Competition is also intensifying. Upbit’s parent company, Dunamu, is pursuing its own listing plans. Whichever exchange reaches the public market first could set the benchmark for Korea’s crypto industry.
Bithumb’s IPO schedule now depends less on target dates and more on completing measurable milestones. The conversion to K-IFRS, progress on the Financial Supervisory Service review, and the planned 2027 preliminary listing application will provide the clearest signals. New regulations, including South Korea’s planned 22% capital gains tax on cryptocurrency beginning Jan. 1, 2027, and broader digital asset legislation, will also shape the operating environment before shares reach the market.
Bithumb has postponed listing plans before, and the company acknowledges the timeline could still change. The difference this time is that every step toward an IPO will unfold under closer regulatory oversight.
South Korea’s Kiwoom Securities is in early negotiations to buy a stake in Bithumb through a private placement, local media reported.
