There was a time when trade negotiators argued about steel, soybeans, and cars. In 2026, the argument is about lithography machines, advanced packaging, and who gets to buy the chips that train frontier AI models. Semiconductors have become the clearest lens through which to read great-power politics.

Why chips carry so much weight

Three facts explain the leverage. First, the supply chain is extraordinarily concentrated: a handful of firms control the most advanced manufacturing, and a single company dominates the machines that make it possible. Second, AI has turned compute into a strategic resource — whoever controls advanced chips influences who can build the most capable models. Third, no country is self-sufficient. Even the biggest economies depend on partners for materials, tools, design software, or fabrication.

The subsidy race

Governments responded with the largest industrial-policy push in decades. The United States, European Union, Japan, India, and others have committed tens of billions of dollars to attract fabs. The result is a construction boom — and a talent crunch. Building a leading-edge fab takes years, thousands of specialized engineers, and enormous quantities of water and power. Money alone doesn’t buy a semiconductor ecosystem; it buys a seat at the table.

Export controls as foreign policy

Export restrictions on advanced chips and chipmaking tools have become a first-resort instrument, updated almost yearly and enforced across allied blocs. The controls create a two-tier world: countries with access to frontier compute and countries engineering around the restrictions — through domestic innovation, gray markets, or cloud loopholes. Every tightening produces a counter-move, and the cat-and-mouse dynamic is now a permanent feature of tech policy.

What to watch

  • Whether new fabs outside East Asia reach volume production on schedule — delays shift the whole power balance.
  • How far advanced packaging and chiplets can substitute for cutting-edge process nodes.
  • Whether export-control coalitions hold as commercial pressure on allied chipmakers grows.

The uncomfortable truth for every capital: chip sovereignty is a spectrum, not a destination. The countries that thrive will be the ones that pick which parts of the stack to own — and which to secure through alliances.
