AI-related investment has grown large enough that economists now compare it to past bubbles, and that concentration cuts both ways. If the big AI bet pays off slowly, the firms supplying the networking gear and servers behind the scenes can still be busy selling into long contract cycles. This article highlights three hardware stocks from our AI connectivity and server screener that sit right in that flow.
The stocks below are just a sample from this AI hardware theme, while the full screen surfaced 22 more companies with equally compelling narratives that are not covered here. To identify and analyze the highest-conviction ideas in this space, head straight to the AI - Networking and Servers screener.
Lumentum Holdings (LITE)
Lumentum Holdings plugs directly into the AI networking and servers theme through the optical modules and photonic components that carry data between high-end switches and GPU-packed racks. Its scale as an integrated enterprise gives that role real weight in the broader hardware chain.
Lumentum Holdings Inc. is a photonics manufacturer focused on semiconductor lasers, optical modules, circuit switches, and industrial lasers that support cloud, AI and telecom networks. It reports about US$3 billion of revenue from a single integrated enterprise segment and has a market cap near US$74.5 billion.
"The core submarket that matters most for long-term value is high-speed optical components for cloud and AI data centers, where bandwidth demand from GPU clusters is driving a rapid upgrade cycle to 800G and 1.6T optics."
What happens to that upgrade cycle if one still largely unseen pressure on future pricing and profitability starts to bite?
If that pricing pressure is on your mind, go straight to the full narrative for Lumentum Holdings for how Lumentum Holdings could still benefit as AI bandwidth demand accelerates.
Jabil (JBL)
Jabil plugs into the AI networking and servers theme as a behind the scenes builder of cloud data center server platforms and rack systems, turning hyperscaler designs into physical hardware at scale.
Jabil Inc. provides engineering, manufacturing, and supply chain services across electronics and electromechanical products for sectors from 5G and cloud to automotive and healthcare, including cloud data center server platforms and chassis work that link it directly to AI infrastructure, and it carries a market cap of about US$29 billion.
"AI related infrastructure programs, with AI revenue guided from about US$9b in fiscal 2025 to roughly US$14.4b in fiscal 2026 and US$22.1b in fiscal 2027 along with an expanded set of hyperscale customers above US$1b each, point to a growing mix of higher value Intelligent Infrastructure work that can lift revenue and core operating margins."
What investors really need to watch is how one pressure point in this AI hardware buildout filters through to Jabil’s future margin profile.
If that margin squeeze is the live question for you, read the full narrative for Jabil to see how Jabil’s AI buildout could still accelerate value creation.
Super Micro Computer (SMCI)
Super Micro Computer builds the kind of dense, GPU-heavy servers and full racks that underpin AI training and inference, which puts it right in the middle of the hardware that connects and houses AI compute for hyperscalers and large data centers.
Super Micro Computer generates about US$39.1b from high performance server solutions, with systems shipped worldwide, and the stock carries a market cap of roughly US$21.3b.
"In March 2026, US prosecutors charged Supermicro co-founder Wally Liaw and others over claims that AI servers worth about $2.5 billion were illegally sold to restricted Chinese customers."
What investors really need to think about is how one unresolved factor could reshape the balance between AI-driven demand and future profitability.
That unresolved factor is exactly what the full narrative for Super Micro Computer unpacks, showing how Super Micro Computer could still turn AI demand into accelerating long term value.
