Market leader in AI chip testing equipment

Advantest, a Japanese company most people have never heard of, just posted record quarterly sales—and its stock now moves in near-lockstep with NVIDIA's. The reason: every advanced AI chip must pass through test equipment before it ships, and Advantest controls nearly 60% of the global market for the machines that do this. As AI spending explodes, chip testing has quietly become one of the supply chain's tightest chokepoints. Yet the company faces intensifying competition: U.S. rival Teradyne is gaining ground in memory testing, and the entire semiconductor equipment sector is experiencing unprecedented demand as chipmakers race to expand capacity for AI accelerators and high-bandwidth memory.
