Arista Networks vs. IBM: Comparing Quarterly Revenue Trends Between These Artificial Intelligence Giants

ANET has posted eight consecutive quarters of revenue growth fueled by AI data center infrastructure demand, while IBM cut its 2026 full-year sales forecast amid headwinds from completed mainframe upgrade cycles and flat consulting division performance.

The divergence highlights structural differences between the two companies. ANET's quarter-over-quarter gains reflect sustained momentum in cloud-scale networking gear as hyperscalers and enterprise clients build out AI training and inference infrastructure. IBM, by contrast, faces cyclical pressure across its diversified portfolio spanning software, hardware, and consulting. The company's mainframe business—historically a revenue anchor—has slowed after enterprises completed recent upgrade waves, and its consulting arm continues to struggle with stagnant performance.

IBM's 2026 sales guidance cut signals management expects near-term weakness to persist across multiple divisions. ANET's streak of consecutive quarterly revenue increases positions it as a direct play on accelerating AI infrastructure spend, with data center switching and routing demand showing no signs of abating.
