⚠️ Not financial advice. The following is informational content only. We may hold positions in securities mentioned. Always do your own research. Full disclosure →
NVDA
Nvidia Deep Dive →
Dominant GPU maker. Powers ~90% of AI training workloads. H100/H200/Blackwell chips are the gold standard.
The picks-and-shovels play everyone knows — but the moat is deeper than it looks.
AMD
AMD Deep Dive →
Rising GPU challenger. MI300X competing with Nvidia H100 in inference workloads. Lower price point.
The credible alternative as hyperscalers diversify away from single-vendor dependency.
AVGO
Broadcom Deep Dive →
Custom AI chips (XPUs) for Google, Meta, Apple. Networking silicon for AI data centers.
Quietly one of the biggest AI infrastructure plays — less talked about, more profitable.
TSM
TSMC Deep Dive →
Fabricates chips for Nvidia, AMD, Apple, and everyone else. No TSMC = no AI chips.
The foundry everyone depends on. Geopolitical risk but irreplaceable position.
AMAT
Applied Materials Deep Dive →
Semiconductor manufacturing equipment. Makes the machines that make the chips.
Deep picks-and-shovels. Benefits from any chip capex cycle regardless of winner.
ASML
ASML Deep Dive →
Sole maker of EUV lithography machines. Without ASML, advanced chips cannot be made.
The most defensible monopoly in tech. Period.

Frequently Asked Questions

What are AI infrastructure stocks?
AI infrastructure stocks are companies that provide the hardware, chips, and equipment needed to build and run AI systems. This includes chip designers like Nvidia and AMD, chip foundries like TSMC, and equipment makers like ASML.
Is Nvidia still a buy in 2026?
This is informational content only — not financial advice. Nvidia maintains dominant market share in AI training chips, but competition from AMD and custom silicon from hyperscalers is growing. Do your own research before investing.
