Cerebras backlog hits $25.4 billion on strength of OpenAI compute agreement
Artificial intelligence chipmaker Cerebras Systems reported a massive $25.4 billion contract backlog driven primarily by a multibillion-dollar infrastructure agreement with OpenAI, highlighting the intense capital commitment required to scale AI inference capacity.
Cerebras Systems concluded the second quarter with $25.4 billion in remaining performance obligations, a contract backlog driven primarily by a massive infrastructure agreement with OpenAI. The artificial intelligence computing specialist reported the figure in its mid-August update, revealing that nearly all of the balance was secured before the current year began.
The company also posted strong near-term financial results, with non-GAAP revenue surging 103 percent year over year to $209.9 million. Management subsequently raised its full-year adjusted revenue guidance to a range between $880 million and $890 million as its inference cloud business nearly quadrupled.
The sheer scale of the backlog requires examining the company's filings, which point to a master relationship agreement signed with the ChatGPT developer in December 2025. That specific contract requires the customer to purchase 750 megawatts of inference computing capacity in an arrangement valued above $20 billion.
OpenAI also retains an option to acquire an additional 1.25 gigawatts of capacity by the end of 2030. Consequently, the remaining performance obligations balance grew only about 3 percent during the first half of 2026, edging up from $24.6 billion at the close of 2025 to $25.0 billion in March and finally to $25.4 billion in June.
Despite the massive headline backlog, the actual conversion into recognized revenue will occur slowly over several years. Cerebras expects to recognize roughly 22 percent of the total, or about $5.6 billion, over the 24 months ending in June 2028.
Another 43 percent of the contracted value should arrive between months 25 and 48, with the remainder following later, though the company notes that timing can shift at the customer's request. During the second quarter alone, Cerebras recognized $56.8 million in revenue from the OpenAI arrangement.
That specific arrangement accounted for approximately 32 percent of the company's $180.1 million in generally accepted accounting principles revenue for the quarter. Overall GAAP revenue expanded 74 percent year over year, underscoring the immediate financial impact of the data center costs passed through to the AI developer.
For investors, the backlog structure illustrates the long-term capital lock-in characteristic of the infrastructure buildout, even as near-term revenue recognition remains constrained by deployment timelines. The heavy reliance on a single customer for the bulk of future obligations also concentrates execution risk within the forward-looking financial profile.
