Micron is building US indium processing after China squeezed exports, adding cost to the chip supply chain.
What happened
China restricted exports of indium, a material critical to semiconductor manufacturing. Micron responded by committing to build domestic US processing capacity. The news moved roughly 500 billion dollars of market value across the sector, but Micron’s stock still dipped on the day.
Why it matters
When a key material’s supply is controlled by a single country, a sudden restriction forces chipmakers to build parallel supply chains at home. That work costs time and money, raising the price of every chip that needs indium. It also hardens the separation between US and Chinese semiconductor ecosystems, making cross-border supply more fragile.
The case against
Building new processing plants takes years, not months, so Micron remains exposed to immediate shortages. The investment also shrinks near-term free cash flow without adding revenue right away, which explains why the stock fell even as the company took the right strategic step.
What settles it
Whether China expands its export curbs to gallium or germanium next, which would signal a broader squeeze on semiconductor materials.
