Reports say SpaceX, OpenAI, and Anthropic may go public soon

In short: Reports say SpaceX, OpenAI, and Anthropic could sell shares to the public soon, and the listings could be among the largest ever if the numbers hold.

What's going on

Several news and market tracking reports are pointing to a possible wave of very large initial public offerings, or IPOs (when a private company starts selling shares on a stock exchange, like opening ownership to the public).

The three names most often mentioned are SpaceX, OpenAI, and Anthropic. All three are private companies tied closely to AI, either by building AI systems directly or by needing large amounts of computing power and data to run them.

One IPO tracking list cited in the reporting says SpaceX filed an S-1 on May 20, 2026. An S-1 is a long set of paperwork a company files before it can list shares in the US. The same tracker says SpaceX could aim for a Nasdaq listing, with an expected valuation of about $1.5 trillion to $1.75 trillion, and pricing possibly in June 2026.

The same watchlist estimates OpenAI at around a $1.0 trillion IPO valuation, with timing in late 2026 or early 2027. It also lists Anthropic at around $300 billion, with a possible 2026 window.

What to watch

These are not confirmed IPOs. Much of the timing and valuation information comes from IPO tracking sites and reporting, not official announcements. If any of these companies do file and price an IPO, the final debut size will depend on the final share price and how many shares are actually sold (like how many slices of the pie get offered to the public on day one).
