Cerebras Systems vs. IonQ: Which Tech Stock Is a Better Buy in 2026?

The article compares two high-performance computing companies: Cerebras Systems, which specializes in AI hardware with wafer-scale chips, and IonQ, which develops quantum computing systems. While Cerebras shows strong 75.7% revenue growth, IonQ demonstrates superior momentum with 202% revenue growth in 2025 and 287% YoY growth in Q2 2026. The author recommends IonQ as the better buy due to its faster scaling, cleaner balance sheet (0.0x debt-to-equity), and positioning in the emerging quantum computing market, despite both companies operating at significant losses.
