3 AI Infrastructure Stocks for Nvidia Data Center Spending

SpaceX lining up up to $40b to fund Nvidia AI chips has turned the usually niche world of accelerators and data center hardware into front-page finance news. That kind of capital hunt signals real money chasing AI infrastructure, not just headlines. This article walks through three stocks from our AI Infrastructure Enablers screener that appear especially exposed to this story and explains why that exposure could matter for your portfolio decisions.

The three stocks highlighted below are only a sample, and the full screen surfaced 48 more large caps with equally compelling AI infrastructure narratives that are not covered here. If you want to identify, compare, and analyze the highest conviction GPU and accelerator enablers, head straight into the AI Infrastructure Enablers (Semiconductors & Data Center Hardware) screener.

MPI (TPEX:6223)

MPI Corporation builds semiconductor manufacturing and testing equipment that chipmakers use to produce advanced processors for AI data centers. It generated about NT$16.4b in revenue from semiconductor equipment and services and has a market value of roughly NT$555.6b, putting it firmly in the large cap bracket for AI infrastructure exposure.

MPI provides focused exposure to the tools needed to turn AI capex budgets into working chips, from probe cards to thermal test systems used by datacenters and emerging computing platforms. The business currently reports strong growth and high profitability, although the impact of heavy external funding on future returns depends on how one unseen pressure plays out.

To see how that pressure could reshape returns, go straight to the 3 key rewards and 2 important warning signs (2 are major!) for the potential fault lines and upside drivers that matter most.

X-FAB Silicon Foundries (ENXTPA:XFAB)

X-FAB Silicon Foundries runs a specialty foundry focused on analog and mixed-signal chips plus silicon photonics, all of which sit in the plumbing of high-speed data movement that AI data centers rely on. The business generated about $846 million from CMOS and MEMS operations and has a market value of roughly €896 million.

X-FAB Silicon Foundries plugs into the AI Infrastructure Enablers story through the less flashy but essential side of the stack, where power management, sensing, and photonics keep data centers stable even as GPU demand ramps. That context makes the company’s current expansion plans worth a closer look.

"Robust expansion of silicon carbide (SiC) manufacturing, with wafer production in the first half of 2025 exceeding all of 2024, is capturing emerging demand from data center power management (linked to sustainability and energy transition themes) and positioning the company for future growth in both revenue and gross margin as these trends accelerate."

What investors still need to weigh is how a single funding and capacity choice could tilt that margin story in either direction.

That hinge point makes it worth reading the full narrative for X-FAB Silicon Foundries to see how X-FAB Silicon Foundries’ capacity bets could be accelerating or masking long term returns.

ACM Research (Shanghai) (SHSE:688082)

ACM Research (Shanghai) supplies cleaning, plating, packaging and other wafer tools that help China produce the chips needed for AI accelerators and data-center processors, generating about CN¥7.2b from semiconductor equipment and services and carrying a market value near CN¥141.9b.

ACM Research (Shanghai) matters for this AI infrastructure screen because its tools help turn rising chip budgets into physically built wafers, and management is leaning into that opportunity with a clear bet on long term demand.

"Expectations that accelerating technological self-sufficiency initiatives in China will structurally boost long-term order flow for domestic equipment suppliers are likely baked into the stock, with investors anticipating ACM will maintain a dominant share in a persistently strong $40B+ China WFE (Wafer Fab Equipment) market."

What really moves the needle from here is whether one assumption about future purchasing power in its home market actually holds up.

If that hinges on future purchasing power, the full narrative for ACM Research (Shanghai) explains how ACM Research (Shanghai) could still surprise if those orders accelerate or stall.
