Baseten is reportedly in talks to raise about $2 billion at valuations up to $30 billion, more than double the $13 billion mark it set in June, according to a Bloomberg report relayed by StrictlyVC.
A senior Figma executive is joining AI inference startup Baseten, another sign that operating talent is flowing from the application layer toward the AI infrastructure layer.
Baseten, Together AI and Crusoe have each raised nine- or ten-figure rounds within the past year, showing AI infrastructure capital increasingly recycling into a small, familiar set of 'neocloud' names rather than funding new entrants.
AI inference provider Baseten closed a $1.5 billion Series F at a $13 billion valuation, the largest funding round of the week, led by Altimeter Capital and Conviction Partners with Spark, Sands and Wellington participating. The raise underscores how serving AI models -- not just training them -- has become one of the most valuable and capital-intensive layers of the stack.
AI inference software provider Baseten raised a $1.5 billion Series F at roughly a $13 billion valuation -- its fourth fundraise in 18 months and the largest US venture round of the week. The company sells the systems software that lets enterprises run AI workloads efficiently, riding the shift in AI spending from one-time training to perpetual, usage-based inference.
AI inference platform Baseten is reportedly raising roughly $1.5 billion at a valuation of up to $13 billion -- tripling its mark in about five months -- co-led by Spark Capital, Sands Capital, Altimeter and Wellington. The round captures investors racing into the layer that actually serves AI models in production, where Baseten's ARR has reportedly jumped from $200M to $600M.
Baseten is the purest bet on the 'inference is the real AI infrastructure' thesis: a $5B company in January, ~$13B by June, with annualized revenue up ~20x year over year. The growth is real because the tailwind is real — every team moving off closed APIs onto open-source models needs a production layer. The risk is that inference is the most contested layer in AI, with hyperscalers and Nvidia sitting directly upstream of Baseten's margins.
Baseten runs usage-based AI inference: customers pay either for API consumption on open-source models or for GPU minutes/hours, with Baseten packaging autoscaling, observability, billing, and developer tooling around it.
Growth is driven by companies moving workloads onto open-source and custom models instead of closed APIs — Baseten is the production layer that makes that switch operationally viable, which is why its annualized revenue tripled in a single quarter.

As companies move workloads off closed APIs and onto open-source and custom models, they need a reliable production layer to serve them at scale — making inference one of AI's most contested infrastructure layers, with platforms like Baseten growing ~20x year over year.
