Fireworks AI reportedly seeks funding at $15 billion valuation, nearly quadrupling its October price tag

Fireworks AI is in discussions to raise a new funding round at a $15 billion valuation, according to Bloomberg. If the deal closes at that number, it would represent a nearly fourfold increase from the company’s $4 billion valuation set during its Series C round in October 2025.

From $552 million to $15 billion in about a year

The Redwood City, California-based company raised $52 million in a Series B back in July 2024, which valued it at $552 million. Just over a year later, the October 2025 Series C brought in $250 million at a $4 billion valuation. That round was co-led by Lightspeed Venture Partners, Index Ventures, and Evantic Capital, with Sequoia Capital also participating.

Total funding raised to date sits at over $327 million.

Founded in 2022, Fireworks AI built its business around providing high-efficiency inference for open-source large language models and other generative AI applications. CEO and co-founder Lin Qiao, a former Meta engineer, has steered the company toward enterprise-grade AI inference, model optimization, and deployment.

The inference gold rush

Fireworks AI has positioned itself in inference, focusing specifically on making inference faster and cheaper for enterprises deploying open-source models. The company processes 15 trillion tokens daily.

Fireworks AI has no public connections to crypto, blockchain, or token markets. This is a pure-play AI infrastructure company competing for enterprise contracts.
