Here’s the full breakdown. Until next week, have a great weekend.

Cerebras Systems Raises $1.1B Series G to Scale AI Supercomputing

Cerebras Systems, the Sunnyvale-based AI processor company, closed a massive $1.1 billion Series G round at an $8.1 billion valuation. The oversubscribed financing – led by Fidelity Management & Research and Atreides Management with participation from Tiger Global, Valor Equity Partners, 1789 Capital, Altimeter, Alpha Wave, and Benchmark – underscores investor confidence in Cerebras’s cutting-edge wafer-scale AI chips.

The infusion will fuel expanded R&D, U.S. manufacturing, and data center capacity as Cerebras scales its third-generation AI supercomputers to meet surging demand from customers like AWS, Meta, and IBM.

Founded in 2016 by Andrew Feldman, Cerebras has made its name on a bold bet: wafer-scale chips that dwarf anything else on the market. Its flagship Wafer-Scale Engine 3 (WSE-3) packs 900,000 AI cores and 4 trillion transistors—56 times larger than the biggest GPU. According to the company, the oversized design cuts out the complex interconnects required in GPU clusters, delivering inference speeds more than 20 times faster than competing chips.

Funding Details:

• Startup: Cerebras Systems

• Investors: Fidelity Management & Research (lead), Atreides Management, Tiger Global, Valor Equity Partners, 1789 Capital, Altimeter Capital, Alpha Wave, Benchmark

• Amount Raised: $1.1 billion
