Forget Nvidia: Google's $200 Billion AI Buildout Could Reward a Different Group
Forget the Nvidia headlines.
By the time the crowd piles into trillion-dollar AI giants, the biggest gains are often gone.
The next wave of wealth may be hiding one layer deeper.
Google is quietly committing roughly $200 billion to build the AI infrastructure that could power its TPU revolution. That means thousands of new servers, miles of optical networking, massive cooling systems, and an entirely new ecosystem of suppliers.
Wall Street is fixated on the companies making AI chips.
We’re looking at the businesses supplying the companies that make the AI revolution possible.
Think of them as the modern-day picks-and-shovels providers for what could become the largest AI infrastructure buildout in history.
Three overlooked companies stand out:
POET Technologies is attacking one of AI’s biggest bottlenecks—moving enormous amounts of data between chips fast enough to keep next-generation AI systems running.
Perma-Pipe provides the specialized cooling infrastructure that gigawatt-scale AI campuses will require as computing power explodes.
Amtech Systems supplies the equipment semiconductor manufacturers need to keep expanding production as AI demand accelerates.
Each company occupies a different link in the AI infrastructure chain. Together, they offer diversified exposure to the buildout itself—not just another bet on AI chips.
If Google’s TPU ecosystem continues expanding at today’s pace, these companies won’t need to become household names.
They just need to keep selling the tools that everyone else depends on.
POET Technologies (NASDAQ: POET)
Company Overview
POET Technologies develops advanced optical engines and photonic integrated circuits that dramatically improve the speed and efficiency of AI networking. As Google’s TPU clusters scale toward millions of processors, moving data between chips becomes just as important as the chips themselves. POET’s technology addresses one of AI’s biggest bottlenecks—high-speed optical connectivity—which positions the company to benefit from the rapid expansion of Google’s AI infrastructure.
Bullish Investment Case
AI clusters require enormous bandwidth between processors.
Google is deploying TPU pods containing thousands of interconnected chips, significantly increasing demand for optical interconnect technology.
POET’s integrated optical engines offer lower power consumption and lower manufacturing costs than conventional optical modules.
The company remains a microcap despite operating in one of the fastest-growing segments of AI infrastructure.
Any meaningful design wins with hyperscale customers could materially re-rate the business.
Optical networking is becoming one of the highest-growth segments of AI infrastructure, regardless of which chip architecture ultimately dominates.

Perma-Pipe International Holdings (NASDAQ: PPIH)
Company Overview
Perma-Pipe supplies specialised insulated piping systems used in district cooling, industrial energy infrastructure and large-scale thermal management projects. While investors focus on AI chips, every hyperscale AI campus requires massive cooling infrastructure. As Google expands gigawatt-scale TPU data centres, demand for industrial cooling systems is likely to grow alongside power consumption.
Bullish Investment Case
AI data centres require sophisticated chilled-water and thermal distribution systems.
Google’s infrastructure strategy includes multiple gigawatt-scale AI campuses requiring extensive cooling infrastructure.
Perma-Pipe has decades of experience supplying critical industrial energy projects worldwide.
The company benefits indirectly from AI capital expenditure without relying on semiconductor demand.
Growing AI infrastructure spending could create a multi-year backlog opportunity.

Amtech Systems (NASDAQ: ASYS)
Company Overview
Amtech Systems manufactures equipment used in semiconductor fabrication, wafer processing and advanced packaging. Google’s commitment to deploying millions of TPUs through Broadcom requires sustained investment across the semiconductor manufacturing ecosystem. As production volumes increase, suppliers of specialised manufacturing equipment should experience rising demand.
Bullish Investment Case
Every new TPU ultimately requires semiconductor processing equipment.
Google’s long-term purchase commitments imply sustained manufacturing demand over several years.
Amtech provides exposure to semiconductor capital spending without relying on a single chip designer.
The business has a strong balance sheet and exposure to multiple semiconductor end markets.
Any acceleration in advanced packaging investment could provide an additional growth catalyst.
