5 Stocks Poised to Win Big as SpaceX Ramps Up AI Infrastructure

Space Exploration Technologies (NASDAQ: SPCX) just upped the ante in the artificial intelligence (AI) infrastructure race, planning to increase its computing capacity by about 10 gigawatts next year, with a moonshot goal of boosting it by 20 gigawatts. That's a huge amount of spending, with Nvidia (NASDAQ: NVDA), SK Hynix (NASDAQ: SKHY), Vertiv (NYSE: VRT), Amphenol (NYSE: APH), and Taiwan Semiconductor Manufacturing (NYSE: TSM) among the biggest beneficiaries.

Let's look at how each of these artificial intelligence stocks could benefit.

1. Nvidia

Nvidia will be the biggest beneficiary of SpaceX's AI infrastructure spree. SpaceX will build its data centers exclusively using Nvidia's Vera Rubin architecture, which means the semiconductor company will supply virtually all the chips and networking for this enormous build-out.

Nvidia gets roughly $40 billion per gigawatt from Vera Rubin, so this could be a $400 billion-plus revenue boost if it doesn't take capacity away from other customers. The current analyst average estimate is for Nvidia to generate roughly $412 billion in revenue this fiscal year (ending January 2027), so this would be a gigantic one-year order from SpaceX.

2. SK Hynix

Without high bandwidth memory (HBM), Nvidia's ultra-expensive graphics processing units (GPUs) can't deliver their full potential in handling AI workloads. As such, HBM has become essential to the AI build-out. However, HBM is currently in short supply, and memory companies' ability to quickly increase supply is limited by their capacity to purchase more extreme ultraviolet (EUV) lithography machines, which are used to make the critical components in both HBM and advanced logic chips, such as GPUs and central processing units (CPUs). This has resulted in a major supply-demand imbalance across the entire memory market, leading to skyrocketing prices across the board.

SK Hynix (NASDAQ: SKHY), meanwhile, looks to be the memory company most likely to benefit from SpaceX's increased AI infrastructure spending, as it is the HBM leader with more than 50% market share and a close relationship with Nvidia. The two companies already have a $500 billion long-term supply deal in place, and SpaceX's spending will only increase demand for HBM and memory in an already constrained market.

3. Vertiv

AI data centers require substantial power delivery and heat removal, which is where Vertiv comes in, providing data center cooling and power management infrastructure. On its Q3 earnings call, SpaceX cited cooling and power as one of the biggest bottlenecks the industry faces. However, it said it has a plan to get to 20 gigawatts of power and cooling equipment by the end of next year.

Although it is not confirmed that Vertiv is a direct supplier to SpaceX's AI data centers, the company should at the very least benefit from increased industry demand in another AI infrastructure market currently facing supply shortages.

4. Amphenol

Amphenol provides power distribution hardware and interconnects that allow data centers to operate at high speeds. Although the company has a wide customer base across industries, data centers are its largest market. Amphenol is a key supply partner to Nvidia and provides important components for Nvidia's Vera Rubin NVL72 system.

The stock is a favorite of Evercore ISI, and analyst Amit Daryanani recently highlighted the company as one of the biggest potential winners from SpaceX's planned AI computing capacity.

5. Taiwan Semiconductor Manufacturing

Any increase in AI infrastructure capital expenditure is generally good news for Taiwan Semiconductor Manufacturing. The company has a virtual monopoly in manufacturing advanced logic chips, including Nvidia's GPUs and CPUs. As such, SpaceX's significant spending on AI infrastructure next year will be beneficial.

The bigger long-term question will be the impact of SpaceX and Tesla's huge planned chip manufacturing facility, Terafab. Elon Musk has said it could start producing chips in volume by Q3 2028, although his track record with timeline predictions isn't the best. TSMC and Musk have talked about TSMC getting involved in the project, but there seems to be a disagreement over who would run the facility. As such, SpaceX's spending will benefit TSMC in 2027, but over the longer term, it's still up in the air.
