Nvidia, TSMC, and Amazon cover the main bases for AI infrastructure: chip design, manufacturing, and cloud computing. Nvidia handles the chip design. They have a near-monopoly on data center AI chips and charge a premium. Even with other tech companies trying to make their own chips, Nvidia's CUDA software remains the industry standard. TSMC does the physical manufacturing. Making high-end chips is too complex for most companies, so the industry relies on TSMC. They expect their AI accelerator demand to grow over 50% annually in the long term. Amazon handles the cloud infrastructure through AWS. Demand is outpacing their capacity right now, leading to a $364 billion backlog. They plan to spend $200 billion this year on new data centers and AI infrastructure to meet the demand.
