OpenAI is set to spend over $20 billion on Cerebras AI chips while also securing a direct ownership stake in the chipmaker. Cerebras has secured a new $850 million credit facility and over $2 billion in recent private funding, fueling its challenge to Nvidia’s market dominance.
The company previously withdrew its 2024 IPO filing but is now preparing to go public amid surging demand for specialized AI hardware and cloud services.
AI chip challenger Cerebras Systems is preparing to file for an initial public offering, marking a sharp reversal from its withdrawn 2024 listing attempt. The renewed push comes as OpenAI finalizes a sweeping agreement to spend more than $20 billion on Cerebras chips, a deal that also grants the ChatGPT maker equity in the company. Under the terms, OpenAI receives warrants for a minority stake in Cerebras, with the potential to increase its ownership as spending scales further. Additionally, OpenAI has committed roughly $1 billion to help fund data center development dedicated to running its AI products on Cerebras hardware.
Founded in 2015, Cerebras has built a reputation around a singular engineering bet: using one massive, wafer-sized chip instead of linking thousands of smaller GPUs. This design aims to train and run large AI models faster and with less complexity than traditional Nvidia-based systems.
The company complements its silicon with proprietary software and cloud services, positioning itself as a streamlined, high-speed alternative for AI workloads. Recently, Cerebras has aggressively expanded into AI cloud services, opened new data centers, partnered with major tech firms, and locked in large-scale compute deals.
The timing of the IPO revival is bolstered by significant recent capital. Cerebras announced the closing of a new five-year syndicated revolving credit facility of up to $850 million, with Morgan Stanley, Citi, Barclays, UBS Investment Bank, Crédit Agricole CIB, MUFG, Mizuho, TD Securities, and Silicon Valley Bank (a division of First Citizens Bank) acting as joint lead arrangers and joint bookrunners.
This credit line follows a $1 billion Series G financing closed in September 2025 and an additional $1 billion Series H in January 2026. The company had originally filed for a public listing in September 2024 but chose to withdraw and raise $1.1 billion privately in October of that year. Now, with OpenAI’s multibillion-dollar commitment and expanding infrastructure demand, Cerebras is moving decisively toward a public debut.
