How IPOGrid covers IPO markets.

Sourcing

IPOGrid prioritizes primary sources. Coverage is grounded in SEC filings on EDGAR (S-1, F-1, 424B prospectuses, 8-A registration statements, 8-K listing events, and the supporting schedules), issuer press releases, exchange listing notices, and reputable market-data references for trading starts and pricing. Every filing referenced on IPOGrid is linked back to its EDGAR source so readers can verify the underlying document.

Secondary sources, including trade publications, analyst notes, and market commentary, provide context. Factual claims about deal structure, pricing, and timing use primary sources.

Deal classification

Weekly Review articles and company pages use separate classifications for conventional IPOs, SPAC initial offerings, de-SPAC merger completions, follow-on offerings, secondary registrations, direct listings, and administrative filing events such as withdrawals or suspensions. Dual-class share structures, insider lock-up terms, and greenshoe allocations are included when disclosed in the filings.

Ambiguous classifications, including rapid S-1 amendments that change deal structure, use the most recent effective filing and include an annotation in the filing timeline.

AI-assisted summaries

Some filing summaries, change summaries, and narrative blurbs are generated with AI assistance. These outputs are limited to facts supported by the underlying SEC document. Human editorial review applies to Weekly Reviews and daily spotlights published under the IPOGrid byline.

Corrections

If an article or company page contains a factual error, outdated deal term, or misclassification, IPOGrid reviews the underlying source and updates the content. Corrections to price ranges, deal size, exchange, trading status, and other material facts are noted inline. Typographical and formatting fixes are applied directly. Corrections can be requested via the contact page.

Independence and conflicts

IPOGrid is editorially independent. It does not accept placement fees, underwriter payments, or issuer sponsorships for coverage. Revenue comes from reader subscriptions and data access described on the pricing page. IPOGrid does not provide investment, legal, tax, or accounting advice; all content is informational and is governed by the terms of service.
