As of September 27, 2026, Bithumb has not filed for an IPO on KOSDAQ or any other exchange; a Korean KOSDAQ listing runs through the Korea Exchange's own preliminary listing review process, not SEC EDGAR, which covers only US filings. The Block reported on August 3, 2026 that Bithumb officially confirmed a three-stage roadmap: 2026 for internal-controls work and a transition to K-IFRS accounting standards, 2027 for filing a preliminary listing review application, and IPO completion on KOSDAQ targeted for 2028. One day later, on August 4, 2026, BigGo Finance reported that Bithumb had rejected a roughly $2.1 million (3 billion won) consumer-dispute mediation payout tied to a botched API trading promotion, a decision the report framed as a fresh headwind to the 2028 IPO plan given other stacking regulatory issues, including FIU sanctions, a Bitcoin-overpayment probe, and a stalled VASP license renewal; the same report noted Bithumb had engaged Samjong KPMG as advisor and Samsung Securities as lead underwriter for the planned listing. Track the Korea Exchange's own disclosures and Bithumb's official statements directly, not secondhand timelines.

Key points

A confirmed roadmap, not a filing

The Block reported on August 3, 2026 that Bithumb officially confirmed a three-stage roadmap to an IPO: 2026 for internal-controls work and a transition to K-IFRS accounting standards, 2027 for filing a preliminary listing review application, and IPO completion on KOSDAQ in 2028.

That is a company-confirmed target timeline, not a listing application or an effective registration. A KOSDAQ listing runs through the Korea Exchange's own preliminary review process, separate from the SEC filings that apply only to US-listed companies.

A payout rejection lands one day later

On August 4, 2026, BigGo Finance reported that Bithumb rejected a roughly $2.1 million (3 billion won) consumer-dispute mediation payout connected to a botched API trading promotion.

The report described the rejection as a fresh headwind to the 2028 IPO plan, stacked on top of other unresolved regulatory issues: FIU sanctions, a Bitcoin-overpayment probe, and a stalled VASP license renewal.

Who's already been hired

The same BigGo Finance report noted that Bithumb had engaged Samjong KPMG as advisor and Samsung Securities as lead underwriter for the planned KOSDAQ listing.

Hiring an advisor and an underwriter shows active preparation, but it is not a filing or a scheduled date. A preliminary listing review application, targeted for 2027 under the roadmap, or an official statement from Bithumb or the Korea Exchange would be the next verifiable step.

Analytical lens

Search intent

Searches like 'When Will Bithumb IPO? A 2028 KOSDAQ Roadmap, Then a Rejected Payout' are research questions: what a filing or a company statement confirms, what has only been reported, and what is still unknown.

What counts as a listing step

For an IPO, the primary record is a registration statement filed with the securities regulator of the listing market, such as an S-1 or F-1 on SEC EDGAR for a US listing. Funding rounds, valuations and secondary-market prices are context, not listing steps.

Segmara role

Segmara takes reviewed pre-IPO allocation requests funded by Stripe USD credits from $25 ($1.00 starter credit); no allocation is guaranteed. It also publishes dated indicative reference marks across 140+ private companies. Nothing on this page is investment advice.
