Anthropic PBC's IPO is casting a long shadow over companies' US listing plans, as they try to find room for their deals to grab attention after the Sept. 7 Labor Day holiday. The Claude developer is preparing to file publicly for an initial public offering that's expected to raise as much as Space X's record $86.2 billion debut, if not more, in the coming weeks.

Investment banks are reportedly vying for roles on the potentially massive offering, which could reshape the competitive landscape for tech IPOs.

Market participants are weighing the potential impact of such a large issuance on existing listings and secondary offerings.

The anticipated size of the deal has already prompted several companies to delay their own public offerings until later in the year.
