100-word summary
Nvidia just invested $2 billion each in Coherent and Lumentum, two companies that make the lasers and optical components connecting AI chips inside data centers. The deals come with multibillion-dollar purchase commitments and guaranteed access to manufacturing capacity. Both suppliers will build new U.S. factories. The message: Nvidia thinks the next AI bottleneck won't be chips, but the fiber optics and lasers shuttling data between them. When the company making GPUs starts locking down the humble components that carry light signals, it's a sign AI infrastructure is moving faster than the supply chain can handle.
