BigBear.ai vs. Cerebras Systems: Which Technology Stock Is a Better Buy in 2026?

The article compares two AI infrastructure companies: BigBear.ai, which provides decision intelligence for government agencies but faces declining revenue and heavy customer concentration, and Cerebras Systems, which builds specialized wafer-scale AI chips and recently achieved profitability with 75.7% year-over-year revenue growth. The author recommends Cerebras as the better speculative bet due to its stronger technology, faster growth trajectory, and institutional backing, while noting both companies remain unprofitable and risky investments.
