Fireworks AI rents computing infrastructure and software that lets businesses run, fine-tune, and deploy open-weight and custom AI models. Rather than building a consumer chatbot, the company sells models customized on customers' proprietary data and workflows. The company reported surpassing $1 billion in annualized revenue and serving more than 40 trillion tokens per day as of July.

The potential valuation jump from $17.5 billion to between $30 billion and $40 billion in a matter of months illustrates how rapidly investor appetite is inflating prices for AI infrastructure companies that sit between raw compute and end applications. The talks also arrive while Fireworks manages fallout from a security incident involving unauthorized access to customer account data, testing whether infrastructure-layer valuations can hold even amid trust concerns. The round, if completed, would follow a $1.5 billion Series D led by Atreides Management, Index Ventures, and TCV as recently as July.
