Why are chip stocks ripping — and which to buy?
The AI race forced Big Tech to open its wallet. That money flows downstream to the semiconductor supply chain. Follow the capital and you'll see who actually makes the money.

How the money flows
ChatGPT's late-2022 launch dragged every Big Tech firm into the AI race. The fear of being left behind opened every wallet at once.
What MSFT, META, AMZN, and GOOGL are pouring into data centers, GPUs, and power. $20–30B per quarter each — over $1T per year combined.
Most of it lands in semis
Building an AI data center is, fundamentally, about buying chips. About half of Big Tech capex flows directly to GPUs, memory, foundry, and equipment. The rest — power, cooling, network — is the adjacent infrastructure that exists to support those chips. The fiercer the AI race, the thicker this flow.
Who actually takes that slice
In each sub-category, the #1 takes the largest share: NVDA in GPUs, SK Hynix in HBM, TSMC in foundry, ASML in equipment. These category leaders are the core beneficiaries. Section 3 below has the full list per category with live prices and one-tap trade buttons.
Semis at a glance
GPU vs CPU
A CPU is a small number of smart cores. A GPU is thousands of simple cores in parallel. AI repeats the same math billions of times, so GPUs crush CPUs. That's why AI = surging GPU demand.
HBM — AI-grade memory
Regular DRAM can't feed GPUs fast enough. HBM stacks memory chips vertically next to the GPU to widen the pipe — purpose-built for AI. It costs 5–10× more than DRAM, so HBM leadership drives memory-company earnings.
DRAM vs NAND
DRAM is short-term working memory (wipes on power-off); NAND is long-term storage (persists). AI demand pushes DRAM — especially HBM — straight up. NAND wins from a different angle: every memory maker is shifting capex into HBM, starving NAND supply. NAND pure-plays (SNDK, Kioxia) ride the supply gap upward as the field empties out.
Foundry — design and manufacture are split
Chip design (NVDA, AMD, AAPL) and chip manufacturing (TSM, Samsung Foundry) are separated. At 3nm/2nm leading-edge nodes, TSMC is effectively a monopoly. Even NVDA can't ship chips without TSMC.
Equipment — why ASML is a monopoly
Making leading-edge chips requires EUV lithography machines, and ASML is the only company on earth that builds them. Each costs hundreds of millions; only dozens ship per year. Smaller, faster AI chips mean more ASML machines, period.
