Prometheus, DeepSeek, Baseten lead $27B+ AI funding in June 2026

June 2026 was dominated by mega funding rounds across AI, infrastructure, and robotics. Prometheus, the physical AI startup led by Jeff Bezos and former Google executive Vik Bajaj, raised $12 billion in Series B at a $41 billion valuation. The company aims to build an “artificial general engineer” to compress product development cycles for jet engines, medical devices, and consumer electronics. Investors include JPMorgan, BlackRock, and Goldman Sachs. Meanwhile, Chinese AI startup DeepSeek raised over $7.4 billion in its first external round at a $50B+ valuation, with Tencent and CATL as lead backers, fueling China's push for domestic AI capabilities. DayOne Data Centers raised $4.5 billion in Series C for AI-ready data centers across Asia-Pacific and Europe, highlighting the physical infrastructure boom. Baseten, an AI inference platform, raised $1.5 billion in Series F at a $13 billion valuation, reflecting the critical layer of inference as enterprises move from experimentation to production.

The funding surge signals a strategic shift: AI investment is no longer limited to software models but is expanding into physical infrastructure, compute capacity, and deployment platforms. Prometheus represents a bet on AI-driven manufacturing and product design, potentially disrupting how physical goods are built. DeepSeek's massive raise underscores global competition for AI leadership, especially as China invests heavily in model development and agent capabilities. DayOne DC and Baseten show that data centers and inference infrastructure are becoming scarce, high-value assets. For professionals, this means faster time-to-market for AI-enabled products, increased compute availability, and more efficient AI deployment at scale, but also growing concentration of capital in a few key players.
