Alphabet (Google) — AI supply-chain exposure

Alphabet is one of the very few companies present at every layer of the AI chain at once. It designs its own TPU accelerators, trains frontier models in-house, and serves them straight into consumer surfaces used by billions as well as to outside customers through its cloud. The model tags it diversified for good reason — it is at once an ASIC producer, a model builder, and an integrator that runs inference on its own hardware, rather than a specialist in any single link.

Its structural hook is vertical integration. Because it makes its own silicon, Alphabet can route parts of its workload around the merchant GPU market that constrains almost everyone else, and it controls the full path from chip design to the product a user touches. Distribution is the other half: an improvement to a model lands instantly in front of an enormous installed base. That combination of in-house compute and captive demand is what gives it centrality without leaning on any one supplier.
