Fireworks AI is in early talks to raise money at a valuation of $30 billion to $40 billion, according to Business Insider. That would be a sharp step up from the $17.5 billion price tag it got on its $1.505 billion Series D in July. The talks are still preliminary, the target could shift, and Fireworks declined to comment. No one has said how big the round would be.
The company has been on a steep climb for months. Tech Funding News first reported $4 billion valuation talks in July 2025. A $250 million Series C came in October 2025 at a $4 billion valuation, led by Lightspeed Venture Partners, Index Ventures, and Evantic, bringing total funding to $327 million. Then, on July 16, 2026, Fireworks announced the much larger Series D, led by Atreides Management, Index Ventures, and TCV, with Nvidia among the existing investors that joined in.
Fireworks says the business has scaled hard since then. It said it passed $1 billion in annualised revenue, up fivefold from the last round. Daily token volume climbed from 15 trillion to more than 40 trillion, and about 95% of those tokens come from models customised on customers’ own data. That is the basic pitch here: companies train and serve their own versions of open models on Fireworks’ platform, rather than just buying generic AI access and hoping for the best.
The company has real customers, at least on paper. Fireworks lists Uber, Shopify, Doximity, Geico, and Revolut, and says Cursor and Harvey use the platform for specialised models. But the timing is awkward. In October, a security incident exposed API keys and tokens in some customer accounts. And while the valuation chatter is loud, the real question is how much revenue has moved since July, because Fireworks has not published a newer figure. On TFN’s math, $30 billion to $40 billion would put the company at 30 to 40 times the run rate it disclosed then.
This is happening alongside a broader rerating of AI infrastructure names. Baseten, Modal Labs, and Together AI have all posted huge jumps in valuation too, and the market is clearly still rewarding anything that sits close to the compute spigot. IDC’s upgraded forecast for AI infrastructure spending only makes that more obvious.
My take — AI-written commentary, not fact-checked reporting
This is what happens when the market confuses demand for discipline. Fireworks is being priced like an infrastructure tollbooth, not a software company, which is great until someone asks why the toll keeps rising every quarter. The whole sector is now auditioning for the title of Most Expensive Shovels in the Gold Rush.
