OpenAI is paying AI-chip startup Cerebras Systems more than $20 billion over three years, Reuters reported April 17 — roughly double its previously disclosed commitment. The deal also grants OpenAI warrants for a minority stake in Cerebras. In an unusual twist, the arrangement is structured as a working-capital deposit: OpenAI is fronting Cerebras around $1 billion to build data centers and carrying that cash as an asset on its own balance sheet instead of expensing it. The move locks in a credible alternative to Nvidia and effectively solves the customer-concentration problem that derailed Cerebras's 2024 IPO. It also underscores the bigger story of 2026 — model leadership now lives or dies on access to chips, power, and data-center footprint, not just algorithms.
