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.

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 is an independent research site. It does not sell, broker, or arrange share purchases, and nothing on this page is investment advice.
How a company reaches a US listing
The SEC filing trail
DraftThe company can first submit a draft registration statement (DRS) for confidential SEC review.
S-1 or F-1The registration statement goes public on SEC EDGAR: Form S-1, or Form F-1 for many foreign companies. A company that used a draft must file publicly at least 15 days before its roadshow.
AmendmentsS-1/A or F-1/A amendments answer SEC comments, and one of them adds the expected price range.
PricingOnce the SEC declares the registration effective, the company sets the price with its underwriters and files the final prospectus, usually a 424B4.
First tradeThe shares start trading on the exchange named in the prospectus, such as Nasdaq or the NYSE.
Bithumb is expected to list outside the US, so its listing documents will not appear on SEC EDGAR, which holds US filings only. Segmara Pro follows listings outside the US in its weekly IPO brief, posted in the members forum, not through EDGAR alerts.
Bithumb officially confirmed a three-stage roadmap to an IPO, reported by The Block on August 3, 2026: 2026 for internal-controls and K-IFRS transition work, 2027 for a preliminary listing review application, and IPO completion on KOSDAQ in 2028.
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 over a botched API trading promotion, a decision the report described as a fresh headwind to the 2028 IPO plan alongside other stacking regulatory issues: FIU sanctions, a Bitcoin-overpayment probe, and a stalled VASP license renewal.
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, a sign of active preparation, not a filing or a confirmed date.
Risk notes
Rumor risk: unofficial dates, valuations, or funding details circulating on social media or forums are frequently wrong or outdated and should not be treated as confirmation of anything.
Illiquidity risk: any private-market interest, indicative marks, or pre-IPO share arrangements in a company that has not listed can be difficult to exit and may not reflect a tradable price.
Timing risk: a company can pause, restart, or abandon IPO preparation at any stage, including after a confidential or public filing, so no step before pricing guarantees a listing.

What is the payout Bithumb rejected, and why does it matter for the IPO?
BigGo Finance reported on August 4, 2026 that Bithumb rejected a roughly $2.1 million (3 billion won) consumer-dispute mediation payout tied to a botched API trading promotion. The report described the rejection as a fresh headwind to the 2028 IPO plan, on top of FIU sanctions, a Bitcoin-overpayment probe, and a stalled VASP license renewal.
Who is advising Bithumb on the listing?
According to the August 4, 2026 BigGo Finance report, Bithumb has engaged Samjong KPMG as advisor and Samsung Securities as lead underwriter for the planned KOSDAQ listing.
Can I buy Bithumb shares before the IPO?
