Cerebras Files for IPO: The AI Chip Startup Taking on Nvidia Just Filed to Go Public

Cerebras Systems — the Sunnyvale-based AI chip startup that has spent nearly a decade building what it calls the fastest AI hardware for training and inference — filed to go public on Friday, April 17, 2026. The company submitted its S-1 registration statement to the US Securities and Exchange Commission, targeting a listing on Nasdaq under the ticker symbol CBRS, with an IPO planned for mid-May 2026. This is Cerebras's second attempt at a public offering. The company first filed for an IPO in September 2024, but withdrew the paperwork after a US national security review of an investment from Abu Dhabi-based technology conglomerate G42 raised concerns about potential access to advanced American AI chips by Chinese entities. That review is now resolved — and Cerebras is back, bigger, better-funded, and with a blockbuster customer contract that changes the story entirely. The Numbers: From Losses to Profit Cerebras's 2025 financials tell a striking story of transformation. The company reported $510 million in revenue for the full year 2025 — up 76% from $290.3 million in 2024 — and posted a net income of $87.9 million, compared to a net loss of $484.8 million the year before. On a GAAP earnings-per-share basis, the company reported a profit of $1.38 per share versus a $9.90-per-share loss in 2024. Looking forward, the company disclosed $24.6 billion in remaining performance obligations as of December 31, 2025 — contracted revenue it expects to recognise over time, with 15% expected in 2026 and 2027. That figure represents an extraordinary pipeline for a company this size and reflects the weight of its headline deal: a multi-year compute agreement with OpenAI valued at over $20 billion. The OpenAI Deal: The Contract That Changed Everything In January 2026, Cerebras announced it would provide OpenAI with up to 750 megawatts of computing power through 2028 — 250 megawatts per year — with OpenAI holding an option to purchase an additional 1.25 gigawatts of computing capacity through Cerebras through 2030. The total value of the expanded relationship exceeds $20 billion, making it one of the largest AI infrastructure contracts on record and by far the largest non-Nvidia AI deal ever signed. The relationship goes deeper than a supply contract. In December 2025, Cerebras issued OpenAI warrants to purchase up to 33.4 million shares of non-voting Class N stock. In January 2026, Cerebras received a $1 billion loan from OpenAI at a 6% annual interest rate to support infrastructure build-out. OpenAI CEO Sam Altman is also listed as a personal investor in Cerebras. CEO Andrew Feldman has not been subtle about what this means competitively: 'Obviously, Nvidia didn't want to lose the fast inference business at OpenAI, and we took that from them.' What Makes Cerebras Different: The Wafer Scale Engine Cerebras's core technology is its Wafer Scale Engine — currently in its third generation, the WSE-3 — which is physically approximately 57 times larger than Nvidia's flagship H100 GPU. The chip is built on a single silicon wafer rather than being cut into individual dies, which eliminates the need for data to travel between chips across PCBs, cables, and racks. Instead, compute cores and memory sit on the same piece of silicon connected by an on-die mesh fabric, dramatically reducing latency and power consumption. The WSE-3 contains over 2.6 trillion transistors and can, according to Cerebras, train AI models up to 24 trillion parameters — more than ten times the size of GPT-4 — without the complex parallelisation software that GPU clusters require. For inference specifically — the process by which AI systems respond to queries — the architecture delivers speed and cost advantages that have allowed Cerebras to win business from customers who found Nvidia's solutions either too slow or too expensive for their specific workloads. The Customer Concentration Risk The most significant caution flag in Cerebras's filing is customer concentration. When the company first filed in 2024, G42 — the Abu Dhabi-based technology conglomerate — accounted for 87% of revenue. That concentration triggered the CFIUS review and ultimately led to G42's voting shares being converted to non-voting shares before clearance was granted in March 2025. In 2025, the picture shifted but the concentration risk did not disappear. G42 accounted for 24% of revenue, while Mohamed bin Zayed University of Artificial Intelligence — a public institution also based in the UAE — contributed 62% of revenue. That means two UAE-linked entities still account for the vast majority of Cerebras's current recognised revenue, even as the OpenAI deal is expected to substantially diversify the customer base from 2026 onwards. The IPO Structure and Backers Cerebras is targeting a Nasdaq listing under the ticker CBRS at a valuation of approximately $22–25 billion, targeting to raise around $2 billion. The company raised $1 billion in a Series H funding round in February 2026 at a $23 billion valuation, following a $1.1 billion Series G in 2025. Investors include Alpha Wave, Benchmark, Eclipse, Fidelity, and Foundation Capital. Morgan Stanley is the lead underwriter, alongside Citigroup, Barclays, and UBS. Earlier this week, Cerebras secured a $250 million revolving credit facility from Morgan Stanley, with an option to expand to $850 million after the IPO. The offering is planned for mid-May 2026. Cerebras was founded in 2016 and employs 708 people as of December 31, 2025. CEO and co-founder Andrew Feldman previously sold server startup SeaMicro to AMD for $355 million in 2012. The company does not currently own the data centres it relies on to offer cloud services, but has indicated it may build its own in the future. Why It Matters: The AI Chip Race Beyond Nvidia Cerebras's IPO filing arrives at a moment when investors are hungry for exposure to AI infrastructure beyond Nvidia — which has faced growing scrutiny over its monopolistic position in GPU supply and the export restrictions limiting its access to key markets. Cerebras represents the most credible independent challenger in the inference chip market: unlike most rivals, it is pursuing a public listing rather than being absorbed by a hyperscaler or chip giant. Its closest architectural rival, Groq, was acquired in a $20 billion deal in 2025, removing the most comparable pure-play inference chip company from the independent market. Anthropic and OpenAI are both reportedly considering public offerings as soon as 2026. The Cerebras IPO, if successful, would be the first major pure-play AI chip company to list publicly in this cycle — and a significant test of whether the market is ready to value AI infrastructure businesses beyond the Nvidia benchmark.
