KLA identified as a leading AI chip equipment pick alongside two other semiconductor equipment suppliers.
Global capital has been flowing steadily toward the United States, with foreign direct investment, dollar demand, and equity market size all moving in the same direction. Growth stocks are increasingly in focus as investors seek exposure to companies that could benefit most from this capital trend. This analysis examines three stocks that demonstrate particular exposure to recent AI infrastructure developments.
**Onto Innovation**
Onto Innovation supplies the process control and metrology tools that chipmakers use to inspect wafers, measure thin films, and manage yields in advanced semiconductor and packaging lines—technologies essential for AI accelerators and high-bandwidth memory. The company generates approximately US$1.1 billion in revenue from semiconductor equipment and services, with a market value of roughly US$15.7 billion.
The company sits at the convergence of rising U.S. capital flows into AI infrastructure and a genuine manufacturing bottleneck. Its tools are closely tied to advanced packaging for AI chips and HBM, with recent results demonstrating strong AI-related revenue and record backlog figures supported by global capital expenditure plans. Forecasts point to rapid earnings and revenue growth, though the stock already trades at a premium valuation, and recent margins have come under pressure, partly due to one-off losses. The clear draw is a company connected to the AI build-out, though this comes with meaningful execution, competition, and cyclicality risks that warrant careful scrutiny before portfolio deployment.
**KLA Corporation**
KLA Corporation builds the inspection, metrology, and process control equipment that chipmakers rely on to detect defects and maintain wafer yields in advanced semiconductor and electronics manufacturing. The bulk of its approximately US$13.6 billion in revenue comes from Semiconductor Process Control at about US$12.2 billion, with smaller but meaningful contributions from PCB and Component Inspection at approximately US$750 million and Specialty Semiconductor Process at approximately US$584 million. KLA is a heavyweight in the sector with a market value around US$261.9 billion.
The company operates at the intersection where rising global capital flows into U.S. AI infrastructure meet the practical necessity of keeping cutting-edge fabs running efficiently. Its tools are closely tied to leading-edge logic, memory, and advanced packaging for AI data centers, supported by strong earnings growth expectations, high margins, and very high forecast return on equity figures indicating a significant profit engine. However, premium valuation, heavy reliance on external borrowing, tariff exposure, China exposure, and recent insider selling all raise questions about how much optimism is already embedded in the current stock price.
**Lam Research**
Lam Research supplies the etch, deposition, and cleaning tools that chipmakers need to build advanced logic and memory chips, from gate-all-around transistors to 3D NAND and packaging for AI processors. The company generated approximately US$23.2 billion in revenue from manufacturing and servicing wafer processing equipment, with all revenue tied to this core segment, and maintains a market value of roughly US$389.7 billion.
The company sits at the heart of the AI build-out attracting rising global capital into U.S. markets, with management highlighting AI-driven wafer fabrication equipment demand in recent earnings updates. High margins and analyst expectations for strong earnings growth have positioned the stock as a clear beneficiary of AI infrastructure spending. However, heavy exposure to China, a premium valuation, and a fully leveraged balance sheet leave little room for disappointment, warranting closer attention before determining fit within a portfolio.
