AI chip developer Etched is fielding investment offers that value the four-year-old company between $40 billion and $50 billion, according to people familiar with the matter. The bids arrive just two months after Etched completed a $700 million funding round in September at a $21 billion valuation.

These fundraising discussions are in early stages, and specific terms could change. Top-tier investors are proposing $40 billion valuations, with other backers offering as much as $50 billion.

Etched builds full AI hardware systems around proprietary chips optimized for inference—the compute step that runs after a user prompt. Co-founder and COO Robert Wachen has said the company designed two new components from scratch to accelerate this workload.

The startup claims its processors handle more tokens faster and at lower cost than Nvidia's offerings. Quant trading firm Jane Street, which led the September round, has already taken early systems. As of July, Etched had secured $1 billion in customer orders.

Manufacturing remains a key test. Etched produced its initial test chip at TSMC during the summer and operates a 10-megawatt data center in Silicon Valley plus a Taiwan facility coordinating production with TSMC.

The economics hinge on execution. If Etched raises at valuations near $40 billion and deploys capital at the burn rate implied by its existing runway, a funding round comparable to its last $700 million would extend operations roughly 3.5 years—a window to prove inference chips can take material share from Nvidia.

Talent concentration at the company signals confidence among engineering hires. Approximately 15 percent of Etched's 400-person workforce previously worked at Nvidia.
