Fireworks valued at $17.5B after $1.5B raise
Fireworks, a cloud startup that hosts open-source AI models for developers, raised $1.5 billion in a funding round that values the company at $17.5 billion. Backed by Nvidia, the San Mateo-based startup said it has exceeded $1 billion in annualized revenue — five times its revenue a year earlier — and now handles roughly 40 trillion AI tokens per day. Fireworks operates in the inference cloud market, competes with major cloud providers to host models, and has formed partnerships (including with Microsoft) while diversifying its customer base beyond early heavy users like Cursor. The round was led by Atreides Management, Index Ventures and TCV, with participation from Nvidia, Evantic and Lightspeed Venture Partners. Fireworks plans to expand headcount and buy more GPUs to support growing demand for cheaper, specialized AI model deployments.
Large funding round and $1B+ annualized revenue for an AI infrastructure startup signals growing demand for cheaper, open-model inference infrastructure and increased competition with major cloud providers; relevant to infrastructure and AI model deployment trends.

Inference Startups Reach Decacorn Valuations on Strong AI Revenue
Investor interest in AI inference providers has surged as several companies report rapid revenue growth and pursue large funding rounds and lofty valuations. Baseten is reportedly raising up to $1 billion at an $11 billion target valuation and has ARR reported to have jumped to $600 million. Fireworks AI is in talks for funding at a $15 billion valuation and announced roughly $800 million in annualized revenue. Modal closed a $355 million Series C and said it crossed $300 million in ARR. Other inference or AI infrastructure players mentioned include Together AI and Fal. VCs cite strong revenue momentum, but margin pressure from high GPU/inference costs, reliance on leased capacity, competition for chip allocations from hyperscalers, and product commoditization remain key risks for sustaining valuations.
AI infra decacorns: Fireworks, Baseten, OpenRouter $113M
Latent Space's AINews roundup (published 2026-05-27) highlights rapid AI infrastructure fundraising and technical trends. The newsletter reports Fireworks and Baseten moving toward decacorn-scale financings (Fireworks cited at ~$15B, Baseten at ~$11B, both described as in-talks/raising). OpenRouter announced a $113M raise and strong production token growth (weekly volume rising from 5T to 25T tokens in six months); coverage notes press discrepancies about whether that round is Series B or Series C. The issue also surveys agent and harness engineering as the key differentiator for coding/ research agents, benchmarks (DeepSWE, Qwen3.7) aligning with developer experience, memory and “sleep”-style consolidation research, optimizer and sparse-attention advances, datacenter power/inference supply concerns, and serving/observability improvements (vLLM Rust frontend, W&B MCP, Cloudflare startups credits). The piece frames routing and multi-model infra as durable platform layers as AI moves from experimentation to production.
Wirestock raises $23M to supply multi-modal AI data
Wirestock, a creative marketplace that pivoted in 2023 from stock distribution to supplying datasets for AI labs, has raised $23 million in a Series A round led by Nava Ventures with participation from SBVP, Formula VC and I2BF Ventures. The company sources images, videos, design assets, gaming and 3D content from a creator base it says exceeds 700,000 contributors, and provides multi-modal datasets to six large foundation-model makers (unnamed). Wirestock reports an annual run-rate of $40 million, has paid $15 million to contributors to date, employs 60 people and will use the funding to hire for research, engineering and product while building enterprise dataset collaboration software for AI labs.
