OpenAI Agrees to Pay Cerebras $20B+ for Chips, May Receive Equity in Return
OpenAI has reached a landmark agreement to pay Cerebras Systems more than $20 billion for access to its AI server chips, according to sources familiar with the deal — double the figure previously associated with the partnership. The agreement also includes the possibility of OpenAI receiving an equity stake in Cerebras, marking an unusual structure for a chip supply deal.
A Deal That Doubles Down
The revised $20 billion figure significantly exceeds what had been publicly reported earlier. For OpenAI, the deal represents a strategic move to reduce its dependence on Nvidia, which has become the dominant — and increasingly constrained — supplier of AI accelerators. By locking in capacity with Cerebras, OpenAI secures access to alternative compute infrastructure at scale.
Why Cerebras, Why Now
Cerebras has built a distinctive position in AI hardware with its Wafer Scale Engine chips, which take a fundamentally different architectural approach from Nvidia's GPU-based systems. Rather than packaging individual dies together, Cerebras fabricates its chips as a single massive wafer — offering different trade-offs around memory bandwidth and inter-chip communication. For certain large-scale training and inference workloads, the approach can be highly competitive.
The Equity Angle
The potential equity component raises the stakes considerably. If OpenAI receives a stake in Cerebras, it would mark one of the most significant strategic investments between an AI software company and a hardware startup. It also creates alignment between the two firms on Cerebras's long-term success — and raises questions about how OpenAI might influence Cerebras's roadmap and pricing.
Timing and the IPO Connection
The deal comes as Cerebras is preparing for a potential IPO. The company is reportedly targeting a raise of $3 billion or more at a valuation exceeding $35 billion — a 60% premium to its $22 billion valuation from just two months ago. A confirmed $20 billion revenue commitment from OpenAI would provide exactly the kind of forward revenue visibility that investors need to justify that premium.
The Bottom Line
OpenAI's $20B+ Cerebras deal is about more than chips — it's a structural bet on AI hardware diversification at the highest possible scale. Whether this accelerates Nvidia's competition or simply complements it, the message is clear: OpenAI is building a compute strategy that doesn't rely on any single supplier.
