The market debut of artificial intelligence start-up Anthropic, a chief rival to OpenAI, could break the record set by SpaceX, US media have reported.

Anthropic plans an IPO that could rival SpaceX's record. IPO by December 31, 2026 at 89% YES.

A first-time share sale topping SpaceX would easily power 2026 to become the best year on record for US IPO volume, data compiled by Bloomberg show.
