DECACORN
Baseten provides high-performance model inference infrastructure — hosting, serving, and optimizing LLMs and custom AI models for production traffic. In June 2026 it closed a $1.5B Series F at up to a $13B valuation (a split-priced round at $11B/$13B) led by Altimeter Capital, Conviction, and Spark Capital, co-led by Sands Capital and Wellington Management — roughly tripling its valuation in five months on annualized revenue that surged from ~$200M to ~$600M in a single quarter (~20x YoY). The platform now serves more than 1 billion inference requests per day across 87 clusters on 18 cloud environments. Earlier, in January 2026, Baseten raised $300M at a $5B valuation with $150M strategic from Nvidia. A direct rival to Together AI, Modal, and Fireworks in the white-hot AI inference market.
