The past year has proved to be transformative for the AI industry in the United States and globally, with substantial funding flowing into the sector. In 2024, 49 startups secured funding rounds exceeding $100 million, according to TechCrunch. Notably, three companies accomplished this feat more than once, while seven companies each raised rounds of $1 billion or greater.
As we approach the end of 2025, the momentum in the AI funding landscape remains strong. So far this year, the number of companies raising significant rounds of $100 million or more has equaled the total for 2024, with a noticeable increase in the number of entities raising multiple rounds of substantial funding.
Here’s a glimpse of the U.S.-based AI companies that have secured $100 million in funding this year:
