Bithumb published a formal three-phase roadmap on August 3, 2026, targeting a 2028 initial public offering. The exchange tied the listing to a shift from K-GAAP to K-IFRS accounting and a spin-off of Bithumb Asset.
Key Takeaways
- Bithumb, South Korea’s second-largest crypto exchange, unveiled a three-phase IPO roadmap this month, aiming to complete the listing by 2028.
- Phase one, per Bithumb, covers 2026: finishing internal-control upgrades and preparing the switch to K-IFRS accounting from the current K-GAAP standard.
- Phase two runs through 2027, when Bithumb plans to file for a preliminary listing review and undergo regulatory examination.
- The roadmap follows a February 2026 error that sent 620,000 BTC, worth roughly $43 billion, to 249 customers who were owed just 620,000 Korean won in BTC.
- Bithumb set up a ₩100 billion ($68 million) Customer Protection Fund and brought in Samjong KPMG as an advisory partner through 2027.
What Happened?
Crypto exchange market share data and broader Crypto exchange volume statistics frame where Bithumb sits before its planned listing. Bithumb’s notice lays out three phases: internal-control and accounting prep in 2026, a preliminary listing review and regulatory examination in 2027, and a completed offering in 2028.
The exchange, per Bithumb’s notice, is working with domestic and international securities firms, law firms, and accounting firms to support valuation, legal review, and listing preparation. Bithumb also confirmed, per Korea Herald’s report, that the timeline could shift depending on market conditions and the pace of regulators’ reviews. a process of building solid trust where customers can trade with greater peace of mind, Bithumb said in the notice, framing the listing as more than a scale play.

The Governance Rebuild Behind the Roadmap
The IPO push does not arrive from a position of routine strength. An earlier staff error during a promotional campaign sent 620,000 BTC to 249 users who were owed just 620,000 Korean won in BTC, briefly cutting the local Bitcoin price by around 17%. Bithumb recovered 99.7% of the phantom balances and covered a 1,788 BTC shortfall from its own corporate reserves.
Read against that backdrop, the roadmap looks like compliance-forced sequencing, not an opportunistic growth bid. That reading lines up with the notice’s own emphasis on risk management “at institutional finance levels” and the separation of Bithumb Asset to remove potential conflicts of interest.
The K-GAAP-to-K-IFRS switch is not a paperwork formality. K-IFRS (Korea-adopted International Financial Reporting Standards) changes how a listing-track exchange must recognize and disclose virtual-asset holdings, a distinction regulators weigh directly in a preliminary listing review.
A Tax Deadline Lands Before the Listing
South Korea’s Deputy Prime Minister Koo Yun-cheol confirmed on July 29, 2026, that a 22% crypto gains tax will take effect on January 1, 2027, with no further delays. Investors earning more than KRW 2.5 million (about $1,740) annually from crypto will fall under the levy.
The sequencing matters: the IPO target lands after the tax activates, so a public Bithumb inherits an already-taxed trading base. Exchanges operating in South Korea’s crypto regulatory enforcement data environment now face compliance costs on two fronts at once: the listing review and the tax rollout.
Implications for South Korea’s Exchange Sector
The Bithumb Asset spin-off does double duty. On paper, it separates business lines to satisfy listing-review governance criteria. It also answers the cross-affiliate conflict-of-interest questions that typically follow a control failure of this scale.
Bithumb’s stated timeline flexibility, tied explicitly to “relevant authorities’ review schedules,” signals that regulators will set the pace of this listing, not the exchange itself. That is a pointed constraint for a company still funding a Customer Protection Fund built to cover its own failure.
CoinLaw’s Takeaway
This roadmap reads as governance-led sequencing rather than a straightforward growth announcement. Bithumb is asking the market to underwrite a listing built on institutional-grade risk controls not long after those same controls failed catastrophically. The K-IFRS transition, the Bithumb Asset spin-off, and the external-adviser buildout are the concrete, checkable steps a preliminary listing review will actually test, not just messaging.
The bigger point is timing: the 2028 target lands after the tax has already reshaped domestic trading, so Bithumb’s revenue base will reflect a taxed, more cautious market. Treat the “flexible” listing date as regulator-controlled, not a company commitment.
