TOKYO — Japan’s Advantest is solidifying its lead in global sales of chip testing equipment, and its share price is hitched to that of chipmaker Nvidia as both ride the growth of generative artificial intelligence.
Advantest and U.S.-based rival Teradyne hold a combined 80% global market share. They long stood neck and neck, but the Japanese player gained the upper hand around 2022, when generative AI began to attract attention.
