Etched Raises $700M at $21B Valuation as AI Chip Startup Doubles Value in a Month

Etched Raises $700 Million at $21 Billion Valuation

AI hardware startup Etched has raised another $700 million at a $21 billion valuation, doubling its valuation in just one month.

The round was led by Jane Street after the quantitative trading firm tested and purchased Etched's AI hardware for its own data center.

Etched was valued at $5 billion in December and raised $300 million at a $10.3 billion valuation in July. The latest financing brings its valuation to $21 billion.

Building Hardware for AI Inference

Etched develops full AI systems called "frontier inference clusters" designed to accelerate inference, the computing process that takes place after a user submits a prompt.

According to co-founder and COO Robert Wachen, AI inference involves two major stages: prefill and decode.

The prefill stage processes the prompt and its context, while the decode stage generates the output tokens that form the model's response.

Etched has developed specialized hardware for both stages.

New Chips and Memory Architecture

The company developed a low-voltage prefill chip that allows it to fit more transistors into the hardware while reducing the heat-related limitations associated with high-end AI chips.

For the decode stage, Etched developed a new memory architecture and interconnect called cluster-scale memory.

The system allows multiple chips to access a shared memory pool at high speed and low latency.

Etched says the combination is designed to increase inference speeds while reducing costs.

Moving Beyond Model-Specific Hardware

Etched initially attracted attention for its plan to build chips optimized around specific AI models.

The company's current systems have moved beyond that approach and can run any frontier model, according to the company.

This broader compatibility expands the potential market for Etched's inference hardware as enterprises and AI companies deploy a growing range of models.

Jane Street Becomes a Customer

Jane Street tested Etched's hardware before participating in the new financing.

The firm has now deployed its own Etched rack in a data center to support demanding workloads.

The investment gives Etched both additional capital and validation from a major quantitative trading firm with significant computing requirements.

Rapid Valuation Growth

Etched's valuation has increased dramatically over the past year.

The company was valued at $5 billion in December before reaching $10.3 billion in July and $21 billion in August.

The latest round brings Etched's total funding to a significantly higher level as investors continue to place large bets on specialized AI inference infrastructure.

Other investors in Etched include Kleiner Perkins, Sequoia Capital, Andreessen Horowitz, Peter Thiel, Tiger Global, Bain Capital Ventures, Neo, Stripes, Primary, Positive Sum, Diffusion, Argo and Blackstone.

Etched is now betting that demand for faster and more cost-efficient AI inference will justify its rapidly rising valuation as AI workloads continue to scale.
