Samsung occupies a position almost nobody else does. It designs its own processors, fabricates them in its own fabs, manufactures other companies’ AI chips on contract, and supplies the high-bandwidth memory that every accelerator on the market needs.
That last business may matter most. An AI accelerator is fundamentally limited by how fast it can move data, and HBM supply has repeatedly been the constraint on how many chips the industry can actually build.
Its foundry sits in an unusual competitive knot: Samsung fabricates silicon for companies whose products compete directly with Samsung’s own, including reported production of Tesla’s AI5 at the Taylor plant in Texas.
