Anthropic’s Mega-IPO Plan Looms Over Packed US Listing Calendar

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 SpaceX’s record $86.2 billion debut, if not more, in the coming weeks.

Some firms and their backers are finding it hard to get the attention of long-term-oriented investors and sovereign wealth funds when the prospect of an Anthropic IPO is imminent, according to people familiar with the preparations.

The rush to get out ahead of a giant IPO feels familiar. A similar dynamic unfolded in the run-up to SpaceX’s listing, when 14 sizable companies went public in the month before Elon Musk’s rocket, satellite and AI firm debuted. Those hurried entries haven’t paid off, with the companies posting a weighted average loss of 9.5%, data compiled by Bloomberg show.

The coming stretch leaves IPO candidates even less room for scheduling than usual, thanks to November’s mid-term elections. Add hotter than expected inflation to the mix, and companies may decide it’s better to dance around Anthropic’s timing than stay on the sidelines.
