Baseten Nears $2B Round at Up to $30B, 2.3x June Mark

TL;DR

  • Baseten is raising about $2 billion in two tranches valuing it at $26 billion then $30 billion, with Sands Capital expected to lead.
  • The top mark is 2.3x the $13 billion valuation Baseten hit in June after its $1.5 billion Series F.
  • Inference rival Fireworks AI raised $1.5 billion in July at a $17.5 billion valuation.

Baseten is in talks to raise about $2 billion across two tranches that would value the AI inference startup at $26 billion in the first segment and $30 billion in the second, Bloomberg reports. Existing investor Sands Capital is expected to lead.

That is roughly 2.3x the $13 billion valuation Baseten reached in June, when it closed a $1.5 billion Series F. Four months.

The reporting frames the raise as reflecting "growing demand for AI inference infrastructure, which supports the operation of artificial intelligence models after their initial training." Baseten's existing backers include Altimeter Capital, IVP and Spark Capital.

Rival Fireworks AI raised $1.5 billion in July at a $17.5 billion valuation. Baseten's prospective top mark sits almost two-thirds above that. Axios reported in September that the talks were at $26 billion; the second-tranche step to $30 billion is the new piece.

Neither Bloomberg nor the available summaries name who else joins Sands at the top of the book, nor whether the two tranches close concurrently or on a staggered schedule. Inference-layer deals have been a running theme across our funding coverage over the past three months.
