FormFactor And 2 Other Top AI Chip Stocks

Bond yields are climbing again as the Federal Reserve signals more work ahead on inflation, and that puts a spotlight on the real plumbing of artificial intelligence hardware. Higher funding costs can punish weaker balance sheets, yet they also push capital toward companies with durable positions in critical chip technology. This article explores three stocks from the semiconductor supply chain screen that sit at the heart of that opportunity.

The three stocks below are just a sample from the idea, and the full screen picked up 13 more semiconductor supply chain companies with equally detailed stories that are not covered here. To size up the wider opportunity set quickly, head straight into the Semiconductor Supply Chain screener to identify, analyze, and focus on the highest conviction AI hardware plays.

FormFactor (FORM)

Overview: FormFactor designs and manufactures probe cards and test systems that let chipmakers and foundries verify advanced AI focused semiconductor devices.

Operations: FormFactor generates about US$801.9 million from Probe Cards and US$178.2 million from Systems, with revenue spread across Taiwan, South Korea, the United States and other key chipmaking regions.

Market Cap: US$7.5b

FormFactor matters in this Semiconductor Supply Chain screen because its probe cards and test systems sit directly in the production lines where AI focused wafers and advanced packages are checked for defects, and the analyst consensus Narrative on Simply Wall St argues that this testing exposure is becoming more valuable as complexity rises.

"Accelerating adoption of generative AI, high performance computing, and HBM DRAM in data centers is continuing to raise test complexity and intensity, and FormFactor’s HBM probe card revenue guidance for the first half of 2026 sits more than 50% above the first half of 2025, which supports the idea that higher average selling prices and a larger test footprint could keep benefiting revenue and earnings."

What happens to that earnings path if one unseen pressure on future margins and capacity expansion assumptions does not break FormFactor’s way?

If that pressure is real, you need the full narrative for FormFactor to see how FormFactor’s AI testing strength could still reshape the risk reward profile for long term holders.

KLA (KLAC)

Overview: KLA supplies inspection, metrology and process control gear that helps chipmakers raise yields on advanced AI focused semiconductor production lines.

Operations: KLA generates about US$13.1b from Semiconductor Process Control, with smaller contributions from Specialty Semiconductor Process and PCB and Component Inspection across key Asian and Western chip regions.

Market Cap: US$209.8b

For the Semiconductor Supply Chain screen, KLA matters because its process control systems are woven directly into AI chip fabs. The bullish analyst Narrative on Simply Wall St argues that this embedded role in inspection and metrology could carry more weight as manufacturing complexity climbs.

"Advanced packaging process control is now guided to about US$1.1 billion in 2026, higher than earlier expectations."

What happens to KLA’s earnings power if one unresolved pressure on future margins and pricing control does not break its way?

If that risk starts to bite, you will want the full narrative for KLA because it lays out how KLA’s pricing power and AI exposure could still accelerate the story.

Lam Research (LRCX)

Overview: Lam Research supplies etch, deposition and cleaning equipment that chipmakers rely on to build advanced logic and memory chips for AI hardware.

Operations: Lam Research generates about US$26.1b from manufacturing and servicing wafer processing tools, with key demand coming from China, Taiwan and Korea.

Market Cap: US$294.7b

Lam Research matters for this Semiconductor Supply Chain screen because its etch and deposition gear directly turns hyperscaler AI budgets into physical chip capacity. Isidrohg, an investor in the Simply Wall St Community who wrote the Narrative, argues that this position lets the business benefit from both tight memory supply and the spending surge that follows.

"NAND conversion pace. The June quarter's doubling is the first real evidence the upgrade cycle has started. If that spending stays front-loaded through calendar 2027 as management expects, FY2027 and FY2028 revenue estimates are too low."

What happens to Lam Research’s earnings power if one unseen pressure on future memory capex and upgrade intensity does not break its way?

If that pressure is real, the full narrative for Lam Research shows how Lam Research’s AI cycle exposure and memory tools could keep accelerating revenue potential beyond the first upgrade wave.
