[AINews] New AI Infra Decacorns: Fireworks, Baseten, with OpenRouter on the Way

[AINews] New AI Infra decacorns: Fireworks, Baseten (with OpenRouter on the way)

Latent Space says Fireworks is in talks for a $15 billion valuation round, Baseten is raising at an $11 billion valuation, and OpenRouter closed a $113 million Series C after volume grew 5x in six months.

Why it matters: HKR-H/K/R all pass: the decacorn hook is clickable, the post gives valuation, round, and usage figures, and the topic speaks to inference economics. Fireworks and Baseten are still reported as in talks or raising, so this stays in the 78–84 band.

Take

Inference infra is being priced as if multimodel production traffic is already inevitable. Fireworks is discussed at $15B, up 3.75x in seven months. Baseten is raising at $11B, up 2.2x in three months. OpenRouter says weekly volume went from 5T to 25T tokens in six months. That usage hook is real; experimentation is turning into production load.

The caution is in the verbs. Fireworks is still “in talks,” and Baseten “is raising.” Those are not closed rounds. OpenRouter also sells a different thing: routing and aggregation, closer to a toll booth across model demand. Fireworks and Baseten live closer to deployment, serving economics, and GPU utilization. Calling all three “inference decacorns” is convenient, but it hides the business-model split that will decide who keeps the margin.
