The week of June 18-26, 2026 saw at least seven AI-focused U.S. startups close large rounds, with Baseten ($1.5B Series F, $13B valuation), Groq ($650M), General Intuition ($320M), Mirendil ($200M seed), and Upscale AI ($190M) collectively representing a concentration of capital in inference infrastructure, foundational model development, and AI networking. Baseten's round, its fourth in 18 months, reflects sustained investor conviction in the systems layer that routes and runs AI workloads, while Groq's raise is notable given Nvidia's recent acquihire of its founding team and technology license. For financial institutions, the pace and scale of private AI infrastructure funding suggests the supply-side build-out remains well-capitalized independently of public-market sentiment, with multiple parallel bets on inference as a bottleneck layer.
