The projected operational IT power capacity for Cerebras Systems as of December 31, 2026, is estimated at a median of 185.0 MW, with an 80% confidence interval ranging from 105.0 MW (p10) to 315.0 MW (p90), and an interquartile range of 135.0 MW (p25) to 245.0 MW (p75). Cerebras has not disclosed a standalone figure for live capacity, historically relying on a combined metric of >600 MW 'live and under contract' for delivery by end-2027 44 sources. The available site and pi
Weighed alongside later-year forecasts, this was maintained close to current levels because it already captures the initial execution constraints that cascade into subsequent years.
The core anchors for Cerebras Systems' data center capacity by the end of 2027 are management's Q2 2026 guidance and its obligations to key customers. Management stated that capacity "live and under contract for delivery by end of 2027" exceeds 600 MW 44 sources. Furthermore, the master agreement with OpenAI reportedly requires a cumulative 500 MW of available capacity by the end of 2027 sec.gov. With over $8 billion in liquidity and $25.4 billion in remaining perf
Set against related questions, the distribution was shifted slightly downward to better reflect the compounded risks of grid and supply chain bottlenecks pushing capacity targets into subsequent years.
The central anchor for capacity at the end of 2028 is the OpenAI master agreement, which calls for a cumulative 750 MW of deployed capacity through multiple tranches 3 sources. By this date, the third 250 MW tranche is expected to be live sec.gov. Additionally, OpenAI holds options for further capacity expansion in 2029 and 2030, with S-1 filings describing potential expansion up to 2 GW 2 sources.
Beyond OpenAI, the broader pipeline suggests material upside. Key suppleme
Set against related questions, the distribution was adjusted slightly lower to account for the likelihood that early-year execution delays cascade into later tranches of capacity deployment.
By the end of 2029, Cerebras is expected to be well into the delivery phase of its massive backlog. The company entered the second half of 2026 with a $25.4B Remaining Performance Obligation (RPO) and over $8B in liquidity. Crucially, roughly 43% of that RPO is expected to be recognized between mid-2028 and mid-2030 investors.cerebras.ai, signaling a multi-year deployment ramp. The baseline for this forecast assumes that the 750 MW OpenAI commitment sec.gov and the 600+ MW baseline reported for 2027 will be
We adjusted the distribution slightly downward to ensure consistency with the cumulative impact of potential energization delays projected in earlier years.
