The startup sector in the United States recorded an exceptional week in terms of funding volume, with artificial intelligence continuing to dominate the investment landscape. Companies developing Agentic AI and dedicated computing infrastructure topped the list of the 10 largest funding rounds for the period between November 7 and 13, 2026.
Key Funding Rounds
- Mirendil: Secured $1 billion in a Series A funding round; the company specializes in developing Agentic AI technologies for research and development purposes.
- Mercor: Raised $750 million in a Series D round, bringing the company's valuation to $20 billion. The platform provides an environment to connect AI developers with human experts to train and evaluate models.
