Nvidia challenger startup Etched secures $500M at $5B valuation to build specialized AI chips

AI chip startup Etched has raised nearly $500 million in a new funding round, pushing its valuation to around $5 billion and bringing total funding close to $1 billion. The round was led by Stripes, with participation from Peter Thiel, Positive SumDealroom has a profile for this one. Try Dealroom →, and Ribbit Capital. The deal ranks among the largest private raises in the increasingly crowded race to build alternatives to Nvidia’s AI hardware.

Founded in 2022 by former Harvard students Chris Zhu, Gavin Uberti,Dealroom has a profile for this one. Try Dealroom → and Robert WachenDealroom has a profile for this one. Try Dealroom →, Etched is taking a highly focused approach to AI chips. Instead of building general-purpose processors, the company is designing custom silicon specifically for transformer-based AI models — the architecture that underpins most modern large language, image, and video models. CTO Mark RossDealroom has a profile for this one. Try Dealroom → joined early to help rethink AI hardware from the silicon level up.

At the center of Etched’s strategy is Sohu, a custom AI inference accelerator. The chip is designed to run transformer workloads far more efficiently than general-purpose GPUs by stripping away support for unrelated tasks. Etched claims that Sohu can deliver dramatic performance and cost improvements, including the ability for a single server to replace large clusters of Nvidia GPUs. These claims, however, have not yet been independently validated through standardized benchmarks.

To manufacture Sohu, Etched is working with TSMC’s Emerging Businesses Group, reportedly using advanced 4nm process technology and high-bandwidth memory. The team has also recruited engineers from established players such as Nvidia, Broadcom and Google DeepMind, blending startup speed with deep industry experience.

The challenge ahead is significant. Nvidia remains overwhelmingly dominant in AI accelerators and is on track to generate hundreds of billions of dollars in data-center revenue by the end of 2026. Etched is not trying to compete head-on across every workload. Instead, it is betting that extreme specialization — doing one type of computation exceptionally well — can carve out a meaningful niche in a market hungry for alternatives.

Execution risk remains high. Key details about Sohu’s production timeline, customer adoption, and real-world performance are still undisclosed, and shifts in AI model architectures could reduce the chip’s relevance over time. Still, Etched’s rapid rise underscores the scale of demand for new approaches to AI infrastructure — and the willingness of investors to back bold bets on focused silicon in a Nvidia-dominated world.
