Bithumb Maps 2028 IPO Timeline as It Tightens Internal Controls

South Korea’s crypto exchange Bithumb said it intends to pursue a preliminary listing review in 2027 and complete an initial public offering (IPO) in 2028. The plan follows a corporate restructuring aimed at clarifying responsibilities across its business units and reducing potential conflicts of interest ahead of regulatory scrutiny.

In its announcement, Bithumb said preparations will include strengthening internal controls and moving from domestic accounting standards to K-IFRS, the international financial reporting framework used by listed companies in South Korea. The exchange added that the schedule could shift depending on market conditions and the timing of reviews by relevant authorities.

Key takeaways

• Bithumb targets a 2027 preliminary listing review and an IPO completion in 2028, subject to regulatory timelines.
• The exchange is restructuring its business, including spinning off Bithumb Asset, to separate responsibilities and limit conflicts of interest.
• Bithumb plans to upgrade internal controls and adopt K-IFRS accounting as part of its listing readiness.
• The IPO push comes amid intensified competition among South Korean exchanges as rivals deepen ties with traditional finance and technology groups.
• Recent issues linked to promotional controls and audits at Bithumb-affiliated listed firms add more scrutiny to the group’s broader compliance posture.

Restructuring and K-IFRS as IPO prerequisites

Bithumb’s statement points to two major adjustments intended to make it more “listing-ready.” First, it has reorganized its business structure, including the spin-off of Bithumb Asset, to sharpen accountability across units and reduce the risk of overlapping interests.

Second, it said it will upgrade internal control systems and switch to K-IFRS from domestic accounting standards. For exchanges preparing for public markets, the shift to K-IFRS typically signals an effort to align financial reporting with the requirements expected of companies after they become subject to broader investor and regulator oversight.

The exchange also cautioned that its timetable is not guaranteed. “Market conditions” and the review schedules of relevant authorities could change the pace of its listing process.

Fiat rails and competitive pressure from legacy finance

Bithumb is one of five South Korean exchanges that support fiat trading via real-name bank accounts, an offering delivered through its partnership with KB Kookmin Bank. That positioning matters because fiat on-ramps and compliance-driven user onboarding are central parts of how South Korean exchanges operate and how regulators evaluate market infrastructure.

Meanwhile, Bithumb’s IPO ambitions arrive as competitors push deeper connections with traditional finance and technology players. According to earlier coverage from Cointelegraph, Mirae Asset Consulting took control of rival exchange Korbit on July 23. Cointelegraph also reported that Upbit operator Dunamu is pursuing a share-swap arrangement that would make it a wholly owned subsidiary of Naver Financial, though completion is contingent on regulatory and shareholder approvals.

This backdrop suggests that Bithumb is not just preparing for capital markets—it is also moving in a landscape where large corporate backers may influence customer acquisition, risk management, and the pace of product and infrastructure development.

A compliance test after a 620,000 BTC crediting mix-up

Bithumb’s listing plans also come with attention on its operational controls. In a February promotional error, Bithumb mistakenly credited customer accounts with balances totaling 620,000 Bitcoin rather than distributing 620,000 Korean won in cash rewards. Cointelegraph previously reported that Bithumb recovered 99.7% of the erroneous credits, while customers sold about 1,788 BTC before account freezing.

At a Feb. 11 National Assembly parliamentary hearing, Bithumb CEO Lee Jae-won said the exchange’s process for checking the intended distribution against its actual holdings had failed, and that the promotional amount was not set aside in a separate account. Reporting on the hearing was carried by Yonhap.

For investors, that incident is relevant even though it involved a promotional mechanism rather than core trading operations. It highlights the importance of robust reconciliation procedures—an area regulators often scrutinize when a company moves from private or quasi-private market activity into public-company oversight.

Audit and listing troubles at Bithumb-linked firms

Bithumb’s IPO preparation is further complicated by audit and listing problems reported for companies linked to the exchange. Cointelegraph noted that Vidente, a major Bithumb shareholder, and Bucket Studio, which indirectly controls Vidente, have had their share trading suspended since March 2023 due to audit and other listing issues.

Yonhap reported that in June, Bucket Studio appointed a former police official as its standing auditor, and that Vidente plans to appoint a former National Tax Service official to the same role. Yonhap also said South Korea’s Government Public Service Ethics Committee cleared both hires after concluding there was no close relationship between the officials’ previous duties and their new roles.

While these developments do not automatically block Bithumb’s own listing timeline, they add another layer of scrutiny to the group’s corporate governance narrative—especially as Bithumb positions internal control upgrades and accounting standard changes as central steps toward public-market readiness.

As 2027 approaches, the key question for readers will be whether Bithumb’s announced restructuring, internal control upgrades, and K-IFRS transition can withstand regulatory review while addressing the operational and governance pressure points already in the public record. Any adjustment to the timetable could offer early signals about how regulators weigh those factors against the exchange’s preparation efforts.
