Benchmark Doubles Down on Cerebras with $225 Million Special Fund

In a major show of confidence, venture capital firm Benchmark Capital has committed at least $225 million to AI chipmaker Cerebras Systems' latest $1 billion funding round. The investment, confirmed by a source with knowledge of the deal, comes as Cerebras achieves a $23 billion valuation—a dramatic rise from its $8.1 billion valuation just six months prior.

Benchmark, an early backer of Cerebras since 2016, structured the investment through two separate funds named 'Benchmark Infrastructure.' This move is notable because the firm typically keeps its funds under $450 million, indicating a targeted, substantial bet on Cerebras's unique technology.

That technology is defined by scale. Cerebras's flagship Wafer Scale Engine chip, announced in 2024, is a single piece of silicon roughly 8.5 inches square, containing 4 trillion transistors. Unlike conventional chips cut from a silicon wafer, Cerebras uses nearly the entire wafer. This design houses 900,000 specialized cores that work in parallel, which the company states allows AI inference tasks to run over 20 times faster than on competing systems by avoiding data transfer bottlenecks between multiple chips.

The fresh capital fuels Cerebras's growing momentum. Last month, the Sunnyvale-based company signed a multi-year deal worth over $10 billion to supply 750 megawatts of computing power to OpenAI, aiming to accelerate response times for complex AI queries.

After a delayed IPO process linked to a national security review of former major investor G42, Cerebras has cleared that hurdle and is now preparing for a public debut in the second quarter of 2026, according to Reuters.
