Axios Pro reports that Baseten is in talks to raise capital at a valuation of about $26 billion. Sources told the publication that the AI-inference company had been approached about doubling its valuation just three months after its last round. The publicly accessible Axios preview does not state the proposed raise size, and the discussions do not represent a closed financing.
Baseten supplies infrastructure that developers use after selecting or building an AI model. A team can deploy an open-source, custom or fine-tuned model, connect it to an application and monitor production requests. Baseten manages the computing and performance layer rather than selling an end-user chatbot.
Baseten’s pre-optimized APIs let developers test workloads, prototype products or evaluate models without configuring a dedicated deployment. Separately, its dedicated-inference product serves custom and open-source models for high-scale workloads. Teams can also train models through its Loops software kit and deploy them for inference on the same technology stack.
Customers can choose a fully managed cloud, a single-tenant cluster or a self-hosted deployment inside their own virtual private cloud. For model labs, Frontier Gateway creates a white-labeled API with authentication, rate limits and usage metering. A separate distribution offering lists models in Baseten’s library, where developers activate them under existing contracts and Baseten handles infrastructure, compliance and billing.
The talks follow a compressed funding cycle. Baseten announced a $1.5 billion Series F at a $13 billion valuation on June 22. It said revenue had increased 20-fold and inference volume 40-fold over the preceding year, while naming customers including Cursor, Notion, Harvey, HubSpot, OpenEvidence and Abridge. A valuation of about $26 billion would be twice the June mark.
