Cerebras Systems: The Smarter AI Play for 2026
Between BigBear.ai’s struggles and Cerebras’ strong growth, the latter stands out as the better AI investment, even from a South African perspective.
BigBear.ai’s recent 19% revenue decline and governance headaches make it hard to trust as a growth stock, especially when its recent uptick comes mostly from acquisitions, not new organic sales. On the flip side, Cerebras Systems posts impressive 75% revenue growth, solid profits, and a unique processor design that’s winning customers and even partnering with Amazon. For South African investors, this isn’t just a distant US tech story; the USD/ZAR tends to reflect demand for big tech exports and investment flows into AI. With Cerebras’ momentum, we could see USD strength from sustained tech demand, keeping the rand pressured. That dynamic alone argues for caution in local cash and a preference for exposure to players benefiting from global AI sell-offs here, like Naspers and Prosus, which offer diversified tech exposure partly insulated from local currency swings. But if US interest rates spike dramatically or AI hype fades suddenly, Cerebras could stumble. this is just our opinion and not financial advice
Avoid BigBear.ai given its weak fundamentals and governance risks. Watch Cerebras closely but prefer indirect exposure via Prosus or Naspers for a cleaner rand hedge and diversified global tech exposure.
- USD/ZAR
- Prosus
- US interest rates surge hurting tech valuations and growth appetite
- Slower-than-expected AI adoption reducing demand for Cerebras processors
6/10
The article compares two AI-focused companies: BigBear.ai, which provides decision intelligence software for government agencies, and Cerebras Systems, which builds wafer-scale processors for AI. BigBear.ai faced a 19.3% revenue decline in FY2025 and reported significant losses, while Cerebras achieved 75.7% revenue growth and turned profitable with a 46.6% net margin. The analyst recommends Cerebras Systems despite its higher valuation, citing stronger growth momentum and customer demand, while BigBear.ai faces governance concerns and must prove sustained revenue expansion.
