Question 1

What is a custom AI chip or ASIC?

Accepted Answer

A custom AI chip, often called an ASIC (Application-Specific Integrated Circuit), is a processor designed to perform one company's specific computing tasks exceptionally well, rather than handling general workloads. Unlike off-the-shelf chips from Nvidia, custom silicon is tailored precisely to a company's AI needs, typically delivering better performance and lower energy consumption. Broadcom (AVGO) is one of the leading designers of these bespoke chips.

Question 2

What is EUV lithography and why does it matter for AI chips?

Accepted Answer

Extreme ultraviolet (EUV) lithography is the technology used to etch incredibly fine circuit patterns onto advanced semiconductor chips. ASML is the world's sole manufacturer of EUV machines, making it an indispensable part of the AI chip supply chain. Without ASML's equipment, no foundry — including TSMC — can produce the next-generation processors that power modern AI infrastructure.

Question 3

What is a semiconductor foundry?

Accepted Answer

A semiconductor foundry is a factory that manufactures chips designed by other companies. Taiwan Semiconductor Manufacturing Company (TSM), commonly known as TSMC, is the world's leading advanced foundry. Broadcom designs Meta's custom AI chips, but relies entirely on TSMC to physically fabricate them at the required level of performance and precision.

Question 4

Is the Meta and Broadcom AI chip deal a good investment opportunity?

Accepted Answer

The Meta-Broadcom partnership through 2029 creates multi-year, contracted revenue visibility for Broadcom (AVGO) and sustained demand across the broader semiconductor supply chain, including TSMC and ASML. This long-duration infrastructure commitment signals genuine strategic intent rather than short-term experimentation. However, all investments carry risk, and concentration in AI infrastructure stocks means exposure to shifts in technology spending, geopolitical tensions, and changes in Meta's strategic priorities.

Question 5

What are the main risks of investing in custom AI silicon stocks?

Accepted Answer

The key risks include heavy customer concentration — Broadcom relies significantly on a small number of large clients like Meta — geopolitical risk around TSMC's Taiwan-based manufacturing, and regulatory export restrictions affecting ASML's sales to certain markets. Additionally, the entire theme is sensitive to slowdowns in AI investment budgets or changes in global trade conditions. Investors may lose money, and today's structural advantages can erode faster than expected.

Question 6

How does the Meta-Broadcom deal affect the wider semiconductor supply chain?

Accepted Answer

The deal creates demand far beyond just Broadcom. TSMC is needed to fabricate the chips, ASML supplies the EUV machines that make advanced fabrication possible, and the broader supply chain — including power management firms, networking providers, and assembly specialists — all benefit from large-scale AI infrastructure buildouts. Nemo's research into this theme deliberately spans multiple layers of that supply chain to capture this breadth of opportunity.

Question 7

Why are big tech companies building their own chips instead of buying from Nvidia?

Accepted Answer

Large technology companies like Meta are moving towards custom silicon because chips built for their specific AI workloads outperform general-purpose processors while consuming less energy. This shift also reduces dependence on external chip vendors, giving companies greater control over their AI infrastructure. The Meta-Broadcom partnership is a direct example of this structural change in how AI compute is designed and deployed.

Question 8

Top 3 stocks in the custom AI silicon investment theme?

Accepted Answer

According to Nemo's research into this theme, the three anchor stocks are Broadcom (AVGO), the chip designer at the heart of the Meta partnership; Taiwan Semiconductor (TSM), the world's leading advanced foundry that fabricates the chips; and ASML (ASML), the sole manufacturer of EUV lithography machines that enable next-generation chip production. These three companies represent the largest holdings by market capitalisation within the theme.

Question 9

Is now a good time to invest in AI chip stocks?

Accepted Answer

The Meta-Broadcom deal running through 2029 signals that AI infrastructure investment is a long-duration trend rather than a short-term cycle. The world's most valuable technology companies are committing enormous capital to AI compute, and that spending flows through a concentrated group of specialist suppliers. That said, timing any investment carries uncertainty, and this theme remains sensitive to changes in technology budgets and global trade conditions.

Question 10

What is the geopolitical risk with TSMC shares?

Accepted Answer

TSMC's manufacturing base is concentrated in Taiwan, meaning any escalation in regional geopolitical tensions could severely disrupt the global semiconductor supply chain. Because virtually every leading-edge AI chip — including those designed by Broadcom for Meta — is fabricated by TSMC, this risk extends well beyond a single company. Investors in this theme should factor this geopolitical sensitivity into their overall risk assessment.

Question 11

How can I invest in custom AI silicon stocks from Africa?

Accepted Answer

Nemo is an ADGM-regulated investment platform that gives investors in Africa access to US stocks including Broadcom (AVGO), Taiwan Semiconductor (TSM), and ASML (ASML) through commission-free trading. You can start with fractional shares from just $1, making it accessible without a large upfront commitment. Nemo also offers AI-powered insights through Nemo AI to help you evaluate themes like custom AI silicon investing.

Question 12

Can I invest in AI chip stocks with a small amount of money?

Accepted Answer

Yes. Through Nemo, you can invest in AI infrastructure stocks such as Broadcom, TSMC, and ASML using fractional shares starting from just $1. This means you do not need to purchase a full share to gain exposure to the custom AI silicon theme. Nemo's commission-free trading model also means smaller investments are not eroded by dealing fees.
