Fireworks AI achieved a significant milestone, surpassing $1 billion in annualized revenue run rate (ARR) as of July 2026.
The company also raised a $1.505 billion Series D funding round at a $17.5 billion valuation, led by Atreides Management, Index Ventures, and TCV, among others.
Fireworks serves over 40 trillion tokens daily, with 95% being custom, specialized AI intelligence trained on proprietary customer data.
The funding will be used to expand compute infrastructure, hire engineering talent, and continue innovating for companies looking to specialize and own their AI models rather than relying on general-purpose systems.
The company’s platform allows businesses to transform general models into domain-specific intelligence with competitive costs and high performance.
