In 2024, U.S. startups raised a total of $209 billion, with artificial intelligence companies such as xAI, OpenAI, and Anthropic leading the funding landscape. AI startups captured approximately one-third of global venture capital, with a notable resurgence in investment. In the fourth quarter alone, over $42 billion was invested in AI-related startups, nearly double the amount from the previous quarter. Nvidia emerged as a dominant player, investing $1 billion in AI startups, surpassing competitors like Amazon and Microsoft. However, investments in AI healthcare have declined sharply, dropping from $22 billion in 2021 to $10.5 billion in 2024, as investors seek more substantial evidence of viability before committing funds. The trend indicates a cooling off in AI healthcare funding, despite the overall growth in the AI sector.
