The biggest raise is SpaceX at $75B (before the option).

Which IPOs are coming next?

Companies on our tracker with an IPO filing on record: SB Energy (public S-1, Sep 1, 2026); Entrata (public S-1, Sep 1, 2026); Syntiant (public S-1, Jul 6, 2026); Anthropic (confidential filing, Jun 1, 2026); Discord (confidential filing, Jan 6, 2026, reported).

Which IPOs were postponed or pulled in 2026?

Oura (Sep 29, 2026); Bamboo Insurance (Sep 22, 2026, reported); Holtec Nuclear (Sep 17, 2026); OpenAI (Sep 12, 2026); Kraken (Sep 2, 2026, reported); Databricks (Jun 4, 2026). Each row on the tracker links the filing or report behind it.

Has OpenAI filed for an IPO?

OpenAI said on Jun 8 it had confidentially submitted an S-1. CEO Sam Altman told Fortune on Sep 12 that OpenAI won’t go public this year. Status on our tracker: postponed as of Sep 12, 2026, per Fortune.

Has Anthropic filed for an IPO?

Anthropic confidentially submitted a draft S-1 on Jun 1, the company said. The >$2T target comes from reports on a leaked draft prospectus; no registration statement is public on EDGAR. Status on our tracker: confidential filing as of Jun 1, 2026, per Anthropic.

How this works: the tracker follows notable US IPOs, not every listing. Each row is checked against an SEC filing, the company's own release or a major outlet, and quotes the line that sets its status; priced rows cite the company's pricing release or the SEC prospectus. A figure sourced from a different page carries its own “src” link. “Reported” means the status rests on media reports, not the company or the SEC. For the analysis behind the pipeline, read who's going public in 2026.
