The artificial intelligence (AI) revolution is sending shockwaves across the technology industry, transforming nearly every facet of business and investing. While high-profile semiconductor giants such as Nvidia, Broadcom, and AMD have captured the headlines — and hefty investor capital — traders are now shifting focus to the often-overlooked suppliers that power the chip-making ecosystem. Companies like Teradyne, Lam Research, and KLA Corporation are experiencing a remarkable surge as investors seek the next wave of growth in AI-driven demand.

Chasing the AI Boom Beyond the Obvious Giants

The insatiable appetite for AI computing power from tech titans like Microsoft, Alphabet, Amazon, and Meta has made semiconductors the centerpiece of global technology markets. According to IDC, worldwide spending on AI-centric systems and infrastructure will exceed $350 billion in 2024, expected to propel growth in every tier of the semiconductor industry.

With valuations for industry leaders like Nvidia and Broadcom reaching as high as 36 times forward earnings, and AI demand still climbing, investors are now searching for more reasonably priced entry points. Semiconductor equipment and testing companies — essential for processing, packaging, and verifying new chips — have emerged as key beneficiaries of the AI gold rush.

Spotlight on Teradyne, Lam Research, and KLA

Teradyne Inc., a leader in semiconductor test solutions, has seen its stock nearly double since its April 2025 lows and is up over 50% since late July. Teradyne’s technology is crucial: advanced chips for AI must pass rigorous testing to ensure reliability and performance. As demand for high-bandwidth memory and cutting-edge processors skyrockets, so does the need for sophisticated testing equipment.

Lam Research Corp. and KLA Corp., top suppliers of wafer fabrication and metrology equipment, have posted spectacular returns. Lam Research enjoyed a 14-session winning streak — its longest ever — with shares climbing 36% in just over two weeks. KLA is similarly up more than 69% year-to-date, both outpacing the Philadelphia Semiconductor Index (SOX).

Momentum Fueled by AI-Capex and Cloud Growth

Major cloud providers continue to announce multi-billion-dollar investments in AI infrastructure. Microsoft and Alphabet are projected to spend over $50 billion combined on data centers and AI hardware in 2025, according to Gartner. This capital expenditure boom requires sustained purchases of advanced manufacturing machinery and testing solutions — core products of Teradyne, Lam, and KLA.

“The market’s clearly front-running the next AI capex wave, betting that fabs and cloud players keep spending aggressively,” explained Haris Khurshid, Chief Investment Officer at Karobaar Capital. “The catch is valuations have already run hard, so any pause in orders or delayed spend could hit fast.”

Strong Tailwinds from Memory and Storage

High-bandwidth memory (HBM), vital for AI computing, is in unprecedented demand. Micron Technology, another chipmaker closely tied to Lam and KLA as suppliers, has seen its shares jump over 90% in 2025. South Korean leaders Samsung Electronics and SK Hynix — major Teradyne customers — are also reaping the benefits. Susquehanna analyst Mehdi Hosseini recently raised Teradyne’s price target to $200 citing a strong outlook for test gear, especially in wafer sorting, which is increasingly linked with big players like Taiwan Semiconductor Manufacturing Company (TSMC).

Emerging Market Risks: Valuations and Cyclicality

While the performance of chip equipment suppliers is impressive, valuations are now climbing swiftly. Lam Research and KLA both started 2025 trading around 20 times forward earnings, but now approach 30 times. By comparison, Broadcom is at 36, and Teradyne reached 33 — even pricier than Nvidia by some metrics.

This rapid appreciation has spurred a round of analyst caution. Both Lam Research and KLA have been downgraded by leading Wall Street firms like KeyBanc, Morgan Stanley, and CFRA, concerned that near-term earnings expectations may not keep up with investor enthusiasm. As Adam Rich, Deputy CIO at Vaughan Nelson, put it: “The rally looks to be on shaky footing, since it seems like exponential investment in AI is the only way for it to keep up, and that seems unlikely.”

What’s Next: AI’s Ripple Effects Through the Supply Chain

AI-driven demand is set to reshape entire value chains, from chip R&D to equipment manufacturing, logistics, and memory production. Suppliers like Teradyne, Lam, and KLA are not just peripheral players — their innovation directly impacts the capacity and speed at which new AI chips come to market.

Meanwhile, geopolitical tensions and tech sector consolidation are layering complexity onto the investment outlook. Leading Asian players in chip memory, including Samsung and SK Hynix, are both partners and competitors to American firms. U.S.-China tensions may further affect the global flow of high-end chip equipment and critical test technologies.

Broader Market Implications

This trend toward “tertiary” AI plays points to a maturing market where pure hype is giving way to strategic bets on infrastructure and supply chain resilience. Still, this evolution brings volatility and puts investors on notice: while the AI trade is hot, the landscape is rapidly changing, and yesterday’s safe bets are now scrutinized for price and sustainability.

In summary, as the thirst for AI accelerates, lesser-known chip equipment suppliers are stepping into the spotlight. For investors, the challenge will be balancing the promise of ongoing AI-driven growth against mounting valuations and the ever-present risk of cyclical downturns. The next chapter for AI-fueled stocks might be just beginning, but caution appears well justified as the pace of investment — and expectations — approaches new highs.
