Here’s the full list of 44 US AI startups that have raised $100M or more in 2024

For some, AI fatigue is real — but clearly venture investors haven’t grown tired of the category.

AI deals continued to dominate venture funding during the third quarter. AI companies raised $18.9 billion in Q3, according to Crunchbase data. That figure represents 28% of all venture funding.

The third quarter also saw the close of the largest venture deal of all time: OpenAI raised a behemoth $6.6 billion round. OpenAI’s deal was one of six AI funding rounds over $1 billion in 2024.
