# Fireworks AI raises $1.505B Series D at $17.5B valuation, crosses $1B annualized revenue run rate

> Fireworks AI has raised a 1.505 billion dollar Series D at a 17.5 billion dollar valuation, led by Atreides Management with Index Ventures and TCV joining. The company says it has crossed a 1 billion dollar annualized revenue run rate, growing roughly fivefold since its October 2025 Series C. Fireworks sells fast, specialized inference infrastructure that helps enterprises run open and custom models efficiently, positioning itself in the increasingly crowded but lucrative layer between raw models and production applications. The scale of the round, and the revenue behind it, reflects how much demand there is for squeezing cost and latency out of AI deployments. The raise fits a clear pattern in this drop: investors are pouring money into the picks and shovels of AI, betting that whoever makes inference cheap and reliable will capture durable value regardless of which foundation model ends up on top.
