KLA Corporation

KLA Corporation is an American semiconductor capital equipment company that designs, manufactures, and services process control and yield management systems used by virtually every major chip manufacturer worldwide, generating $12.16 billion in revenue in fiscal 2025. The company occupies an unusual position in the semiconductor ecosystem: it is the dominant supplier of inspection and metrology tools that determine whether a wafer is good enough to keep building on, and its market share in process control — roughly six times that of its nearest competitor — makes it closer to a franchise than a participant.

This is a story about structural advantage meeting an extraordinary demand moment. The AI infrastructure build-out is driving wafer fabrication equipment spending toward approximately $150 billion in calendar 2026, and process control intensity — the proportion of fab equipment spend dedicated to inspection and metrology — continues to rise as chip architectures grow more complex and the cost of failure escalates. KLA is the primary beneficiary of both trends. The file turns on a single question: whether the current growth acceleration represents a durable step-change in the company's addressable market, or whether it is a powerful but ultimately cyclical upswing that will mean-revert when the AI investment cycle matures.

KLA completed a 10-for-1 stock split on June 11, 2026. All per-share figures in this article that pre-date the split are stated on a pre-split basis unless explicitly noted otherwise; post-split equivalents divide by ten.
