Marvell Technology (MRVL)

Overview: Marvell Technology designs and sells high performance semiconductor chips that sit at the core of modern AI data centers, cloud storage and networking, helping move and process data quickly between servers, memory and devices across the globe.

Operations: Marvell generates about US$8.7b from designing, developing and selling integrated circuits, with revenue focused on China (US$3.3b), other international markets (US$2.5b), Taiwan (US$1.8b) and the United States (US$1.0b).

Market Cap: US$252.7b

Marvell sits at the heart of AI infrastructure, supplying custom chips, optical interconnects and CXL switches that big cloud providers are using to build ever larger AI clusters. This role has been highlighted by Nvidia’s US$2b investment and collaborations around NVLink Fusion. Management commentary points to strong AI data center demand. However, the stock currently carries a very high P/E and trades well above one DCF-based fair value estimate, so expectations are tight. Heavy reliance on hyperscaler capex, tariff uncertainty and recent insider selling add to the risk side of the equation. For investors seeking exposure to AI hardware plumbing with both notable growth drivers and valuation pressure already reflected in the share price, Marvell may warrant further research.

Marvell’s AI plumbing story is accelerating, but a stretched P/E and hyperscaler dependence raise big questions about what is already priced in. Get the full picture in the 2 key rewards and 3 important warning signs

Advanced Micro Devices (AMD)

Overview: Advanced Micro Devices is a global semiconductor company that supplies CPUs, GPUs and AI accelerators used in data centers, PCs, gaming consoles and embedded systems, helping power everything from cloud AI training to high end gaming and automotive applications.

Operations: AMD generates about US$37.5b in revenue, led by its Data Center segment at US$18.7b, followed by Client at US$11.2b, Gaming at US$4.0b and Embedded at US$3.5b.

Market Cap: US$775.4b

Investors watching AI infrastructure may consider AMD, which supplies AI accelerators, EPYC data center CPUs and adaptive chips for the same surge in AI related compute that is driving global trade in AI goods faster than many other categories. Recent earnings report data center and AI offerings as a key focus area, and management commentary notes broadening demand for both GPU and CPU compute as agentic AI and complex workloads scale. At the same time, AMD trades at a rich valuation, faces intense competition from Nvidia, custom chips and export controls, and relies on heavy investment and external borrowing, while insiders have been selling stock. A central consideration for investors is whether current expectations already reflect most of the potential from this AI opportunity or leave room for further upside in execution and earnings quality.

AMD’s AI story looks powerful, but the real tension is whether expectations already stretch too far or still underestimate the upside. Get the unfiltered view in the analyst forecasts for Advanced Micro Devices

Arm Holdings (ARM)

Overview: Arm Holdings licenses the chip designs and computing platforms that sit inside billions of devices, from smartphones and cars to cloud servers and AI hardware, collecting royalties every time partners ship a chip using its IP.

Operations: Arm generates about US$4.9b from semiconductor equipment and services, with revenue concentrated in the United States at US$1.8b, followed by the PRC at US$874m, Japan at US$825m, Taiwan at US$695m, the Republic of Korea at US$392m and other countries at US$373m.

Market Cap: US$370.0b

Arm sits at the crossroads of the AI boom, with its energy efficient architecture in smartphones, edge devices and a growing share of AI data center CPUs, while global trade in AI related goods is expanding far faster than other categories. The company benefits from rising royalty rates on newer platforms and strong licensing demand tied to AI workloads. However, the stock trades at a heavy premium to several valuation metrics and relies on ongoing execution in new areas such as compute subsystems and AGI focused CPUs. In addition, customer concentration in premium smartphones, exposure to China and an FTC probe into licensing create a powerful AI IP story that also carries meaningful execution and regulatory risk that investors will want to understand more deeply.

Arm’s royalty flywheel and AI reach look powerful, but the real surprise might be where growth is coming from next. Get the context and key pressure points in the analyst forecasts for Arm Holdings
