The Holy Trinity of Hardware
It is practically impossible to discuss this sector without mentioning NVIDIA. Their graphics chips, originally built so teenagers could play video games, accidentally became the engine of the AI revolution. It is a brilliant fluke. But they do not just sell chips. They sell a deeply embedded platform that makes it incredibly painful for customers to switch.
Then we have Broadcom. I think of them as the indispensable traffic wardens of the data centre. They build the digital motorways that connect everything together.
Finally, there is Micron. We have a memory problem that nobody talks about enough. AI needs high-bandwidth memory to move data at terrifying speeds. Micron sits squarely at this strategic chokepoint.
They control the bottlenecks, and bottlenecks dictate pricing power.
