AI’s Next Bottlenecks Create New Winners
As the AI boom strains more than just chips, several niche plays stand to gain.
Everyone knows Nvidia leads the AI chip race, but supply can’t keep up, and that’s causing a domino effect. Memory makers like Micron are where real demand is exploding now, backing up the data flow for AI engines. Then there’s the unsung heroes: companies supplying optical connectivity (Lumentum, Coherent) and clean power or cooling solutions (GE Vernova, Bloom Energy, Vertiv). In South Africa, these trends mostly echo through the rand, as capital for tech infrastructure rides on USD/ZAR moves. Local data centers and tech-heavy banks are watching this closely—Standard Bank and FirstRand, for instance, might benefit indirectly via better tech adoption and stability. The big risk? If AI hype fades quickly or new tech bypasses these layers, many of these stocks could stall. Yet, for now, the supply chain complexity means these seven deserve a spot on watch lists. this is just our opinion and not financial advice
On the JSE, keep an eye on USD/ZAR currency moves as a proxy for global tech demand. Consider a small exposure to Standard Bank or FirstRand on improving digital infrastructure momentum. Globally, trim Nvidia as capacity issues persist and focus more on memory (Micron) and infrastructure-related tech.

As AI infrastructure expands, companies face multiple bottlenecks beyond chip production, including memory, power, cooling, and connectivity. Seven companies addressing these constraints—Nvidia, Micron, Lumentum, Coherent, GE Vernova, Bloom Energy, and Vertiv—are positioned to benefit as the industry shifts from one bottleneck to another.
