AI inference startup Baseten reportedly raising $1.5B months after its last mega round https://techcrunch.com/2026/06/18/ai-inference-startup-baseten-reportedly
AI inference company Baseten is reportedly in the final stages of securing a $1.5 billion funding round, which would value the startup at $13 billion. This comes just five months after Baseten raised $300 million at a $5 billion valuation, and nine months after a $150 million Series D. The new round is described as "split-priced," with some investors valuing the company at $13 billion and others at $11 billion. The funding is being co-led by Spark Capital, Sands Capital, Altimeter Capital, and Wellington Management, and is seen as part of a broader trend of significant investment in the AI inference layer.
