AI chip startup Etched announced on August 18, 2026, that it has secured $700 million in new funding, bringing its valuation to $21 billion. This valuation nearly doubles the $10.3 billion valuation Etched achieved in a $300 million Series C round concluded on July 23, 2026. The latest funding round was led by Jane Street, a quantitative trading firm that has also become Etched's first customer.
Jane Street recently took delivery of Etched's first shipped AI cluster system and has begun deploying it for its workloads. The firm stated it tested the chip and found its "unique approach to inference delivers the precision we will need to support our most demanding workloads." This customer validation by Jane Street, a sophisticated user of technology, appears to have been a key factor in the rapid valuation increase. Jane Street's dual role as lead investor and early customer creates a strong alignment of incentives for the firm.
Etched, founded in 2022 by Harvard dropouts Gavin Uberti, Chris Zhu, and Robert Wachen, designs specialized hardware for AI inference. The company's products are full rack systems optimized for the inference portion of the AI compute stack, which occurs after AI models have been trained and are used to generate responses. Etched argues that its focus on inference allows for more efficient chips compared to general-purpose GPUs, which are designed for both training and inference. The company's technology splits inference work into prefill and decode phases, employing low-voltage chips and a Cluster Scale Memory design for improved performance and efficiency.
The company has attracted significant talent, employing over 400 people, including engineers recruited from industry leaders such as NVIDIA, Google's TPU team, Broadcom, and SK Hynix. Etched has stated it holds more than $1 billion in signed customer contracts, though Jane Street is the only customer publicly named. The rapid succession of funding rounds and the company's focus on inference hardware highlight a broader market trend of seeking alternatives to NVIDIA's dominant position in AI silicon.
Prior to the latest funding, Etched had raised $1.9 billion in total funding. This included a $300 million Series C round on July 23, 2026, which valued the company at $10.3 billion and was led by Sequoia Capital. Before that, Etched was valued at $5 billion in December 2025. The company also disclosed an additional $800 million gathered across four previously unannounced financings, supported by strategic backing from VentureTech Alliance to strengthen its manufacturing partnership with TSMC.
The company's rapid execution includes achieving first-pass silicon success in under three years from seed funding and emerging from stealth in June 2026 with a working chip. Etched plans to accelerate production to meet demand from its growing customer base.
