The Cerebras IPO filing isn’t the same mess as before
Brief
Cerebras is pursuing an IPO after re‑filing with materially different dynamics: strong top‑line growth and strategic hyperscaler/lab deals have reduced its historical concentration risk. The company posted $510.0M in 2025 revenue (hardware $358.4M, cloud/services $151.6M), with sequential quarterly growth of +31% and +26% in the latest two quarters, though gross margin slipped to 39.0% as costs rose. Historically dominated by Abu Dhabi customers (G42/MBZUAI), Cerebras closed a January 2026 multi‑year agreement with OpenAI to deploy 750 MW (option to scale to 2.0 GW) that includes a $1B term loan and warrants, and a March 2026 AWS partnership to deploy CS‑3 systems integrated with Trainium3 for disaggregated inference. With $24.6B RPOs and near‑breakeven results excluding stock‑based comp, the IPO case rests on continued expansion of AI inference demand and adoption of purpose‑built wafer‑scale inference chips.
Why it matters
Cerebras reported calendar 2025 revenue of $510.0M (up 76% YoY): hardware sales grew 69% to $358.4M and cloud & services grew 94% to $151.6M; cost of revenue rose 86% and gross margin fell to 39.0% from 42.3%.
Key details
- Customer concentration improved but remains notable: G42 accounted for 85.0% of 2024 revenue and 24.0% of 2025 revenue; MBZUAI accounted for 62.0% of 2025 revenue and represented 77.9% of accounts receivable at 12/31/2025 (G42 was 91.0% AR at 12/31/2024).
- Strategic commercial deals inked in 2026 materially de‑risk revenue: a January 2026 multi‑year OpenAI agreement to deploy 750 MW of Cerebras wafer‑scale systems (option to expand up to 2.0 GW), including a $1.0B term loan and tranched warrants; and a March 2026 AWS deal to deploy CS‑3 systems and co‑design an inference solution integrating AWS Trainium3 with Cerebras CS‑3.
- Near breakeven unit economics before stock‑based comp: stripping $11.3M and $16.0M of SBC from the final two quarters of 2025 leaves the business close to breakeven; remaining performance obligations (RPOs) were $24.6B, with ~$3.69B recognized in 2026–27 and ~$10.59B in 2028–29.
