Baseten in Talks for $2 Billion Round at $30 Billion Valuation

Baseten, a San Francisco-based AI inference startup, is in talks to raise about $2 billion at a valuation of up to $30 billion, according to market sources — more than double the $13 billion valuation it secured in June.

If the terms hold, the company will have more than doubled its price tag in a matter of months. That pace, by any measure of private-market history, is aggressive. The deal is not final: terms remain under negotiation, and the final amount and valuation could change, the sources said.

How is the round structured?

The new round is understood to come in two tranches. The first tranche carries a $26 billion valuation. The second tranche rises to $30 billion. Existing shareholder Sands Capital is expected to lead the round, according to the sources.

A two-tranche structure lets investors commit at a lower price first and pay the higher price only when the second portion closes. It also locks in the startup's momentum: the higher tranche signals where backers think the business is heading.

The raise follows Baseten's June financing, when it raised $1.5 billion at a $13 billion valuation and announced the completion of its Series F in a June 22 post on its corporate blog.

What does Baseten actually sell?

Founded in 2019, Baseten helps enterprises move trained AI models into live production environments. The company provides inference software and related services. Inference is the step where a trained model actually runs and generates outputs — the computing that happens every time a user gets a response from an AI application.

Baseten publishes customer case studies on its website. Nvidia has also featured the startup in a case study on cloud-scale AI inference, showing how Baseten applies its technology in real deployments.

The distinction matters for investors. Training large models grabbed the early AI capital. Inference is the recurring cost: as AI applications expand, demand for computing power rises in tandem, and that demand repeats with every query.

Who else is raising in inference?

Baseten is not the only inference infrastructure company commanding steep prices. Peer Fireworks AI raised $1.5 billion in July at a $17.5 billion valuation, another data point showing sustained investor interest in the segment.

The pattern is consistent across the two deals:

• Baseten: $1.5 billion raised in June at $13 billion; now targeting $2 billion at up to $30 billion.
• Fireworks AI: $1.5 billion raised in July at $17.5 billion.
• Both companies operate in inference, the layer that runs trained models in production.

Together the rounds show capital flowing rapidly into AI inference. Investors are treating the segment as core infrastructure for the next wave of AI applications rather than a niche service.

What happens next?

The negotiation will determine whether Baseten lands at $26 billion, $30 billion, or another figure entirely. What is already clear is the direction: investors are paying twice what they paid in June for the same business, roughly five months later. That repricing, if completed, will set a fresh benchmark for what private markets will pay for inference infrastructure — and will pressure rivals to test whether their own valuations can move at the same speed.
