Fireworks AI Raises $1.5B Series D at $17.5B Valuation

Fireworks AI raised $1.5 billion in Series D funding at a $17.5 billion valuation, the company announced Thursday. The round's lead investors included Atreides Management and Index Ventures. TCV also served as a co-lead. Existing investors Evantic and Lightspeed Venture Partners participated, as did NVIDIA.

Fireworks offers a platform for specialized intelligence, letting companies like Uber and Shopify train and serve custom models. The startup says its infrastructure handles training, fine-tuning, and inference for proprietary AI workloads.

NVIDIA, which already provides hardware for Fireworks' inference stack, joined as a strategic investor. The NVDA stock page trades near $207, down 2.57% on the session.

The new capital brings Fireworks' total funding to roughly $2.2 billion.
