On July 30, 2026, Beijing time, 36Kr reported that food supply chain tech company GrubMarket has submitted a confidential Form S-1 draft to the U.S. Securities and Exchange Commission (SEC) for its proposed public offering of common stock. This media item was published at 06:50:16 UTC on July 30, entering the latest 24-hour news window. The company confirmed that it has submitted a confidential draft rather than an official filing; the SEC has not announced the effectiveness of the issuance, and shares have not yet begun trading or sales. These two procedural statuses should not be conflated.

Company Announcement and S-1 Information Scope

GrubMarket issued an announcement from South San Francisco at 08:18 Eastern Time on July 28, stating that the draft corresponds to a proposed public offering of common stock. The company has not determined the number of shares or price range for issuance and limits subsequent progress conditions to completing SEC review, market environment, and other conditions. The announcement does not provide dates for filing, roadshow, effectiveness, or first trading day, nor does it commit to the completion of transactions; changes in market conditions may still affect future progress.

The SEC lists Form S-1 as a basic registration statement form that companies can use. The public version's first part is typically an offering prospectus for investors, which must explain business operations, financial condition, operating results, risk factors, and management, along with audited financial statements; the second part also includes supplementary information and attachments. GrubMarket has submitted a confidential draft at this stage, so the company materials cannot yet be verified from public documents, nor can external readers assess specific transaction terms based on these.

Confidential Review and Public Filing Period

According to SEC guidelines, confidential review uses the DRS submission type in the EDGAR system; issuers wishing to apply for confidentiality under Rule 83 can also electronically submit requests through the DRSLTR type. Choosing a confidential draft allows related EDGAR account information to remain non-public until public filing. This arrangement enables regulators to pre-review drafts, but voluntary submissions do not constitute formal public filings of registration statements. The initiation of regulatory review does not imply approval or effectiveness of issuance.

For an IPO using confidential review, issuers must still publicly file the registration statement, initial confidential draft, and all revisions at least 15 days before the roadshow; if there is no roadshow, related materials must be filed at least 15 days before effectiveness. This period comes from general SEC procedural guidelines and does not represent GrubMarket's already announced listing schedule. The company announcement did not specify when this public phase would begin or whether a roadshow has been scheduled.

Complete Filing and Securities Law Boundaries

The SEC also requires that the first public registration statement should include complete signatures, signed audit reports, necessary consents, attachments, and corresponding filing fees. No registration fee is required for a confidential draft submission; the fee becomes due when the registration statement is publicly filed for the first time. At this stage, there are no public documents to confirm GrubMarket's audited financial data, equity structure, risk factors, management disclosures, or use of proceeds from issuance; these items will be available in complete filing materials.

GrubMarket notes that its announcement was issued under Rule 135 of the U.S. Securities Act of 1933 and does not constitute an offer to sell securities nor a solicitation for purchase. Any future offers, solicitations, or sales must still comply with registration requirements under securities law. Therefore, the only confirmed company action at this stage is the submission of a confidential draft for proposed issuance; it cannot be written as having raised funds, determined investors, or completed an IPO.

Media Abbreviations and Verification Points

36Kr's headline abbreviates the event to GrubMarket secretly submitting its U.S. IPO draft, while more precise terms used in company announcements and SEC guidelines are 'confidential submission of Form S-1 draft.' The announcement location is South San Francisco, but the company has not designated an exchange listing, stock code, underwriting group, or arrangements beyond the proposed issuance territory. Issuance scale and price range remain undetermined; existing materials do not provide enough information to estimate expected fundraising amounts or determine the final public market location.

The next publicly verifiable key material will be GrubMarket's formal submission of the registration statement along with the disclosure of confidential drafts and revisions. At that time, it may be possible to see share numbers, price ranges, use of proceeds, financial data, risk factors, and underwriting arrangements; roadshow, effectiveness, and trading dates still need confirmation from company or regulatory documents. Historical valuations mentioned in 36Kr's summary have not been verified by this company announcement or SEC materials; these figures are not included in the issuance information nor used to infer issuance valuation or make any additional numerical projections.
