Cerebras Systems (CBRS) down 28% after mega-cloud-AI deals shift inference model toward lower-margin cloud.

Cerebras is now a bet on its ability to turn wafer-scale AI chips and its new AI cloud into recurring, profitable compute capacity. The OpenAI and AWS agreements keep the main near-term catalyst intact: execution on those multi-year contracts. The biggest current risk is that lower guided gross margins and heavy data center spending make the path to stronger profitability more uncertain, despite the impressive revenue growth.

The multi-year, more than US$20 billion OpenAI compute agreement is the announcement that really stands out. It directly ties Cerebras' cloud buildout and leasing model to a single, very large customer, reinforcing both the utilization upside and the concentration and margin risks investors now need to weigh more carefully.

Yet behind the headline OpenAI win, investors should be aware that customer concentration and thinner margins could both matter significantly.

Cerebras Systems' narrative projects $7.6 billion in revenue and $1.7 billion in earnings by 2029. This requires 145.9% yearly revenue growth and roughly a $1.6 billion earnings increase from $87.9 million today.

According to Simply Wall St's analysis, Cerebras' forecasts yield a $299.30 fair value, representing a 78% upside to its current price. Seven fair value estimates from the Simply Wall St Community span roughly US$100 to over US$1,350 per share, showing how far apart market views can be. As investors weigh these valuations against Cerebras' margin compression and heavy data center commitments, it is worth comparing several of these perspectives before deciding how its current performance might shape future outcomes.
