Lumentum Joins Nasdaq-100 as AI Optics Demand Surges
Lumentum Holdings Inc. (Nasdaq: LITE) supplies lasers, modules and optical subsystems that move data through cloud and AI networks. Its technology has become more strategically important as larger AI clusters require faster links with lower power consumption. The company’s position was reinforced on March 2, 2026, when NVIDIA agreed to invest $2 billion under multiyear arrangements covering advanced laser purchases, capacity access, U.S. manufacturing expansion, and research and development.
Nasdaq said on May 8, 2026, that Lumentum would join the Nasdaq-100 before trading opened on May 18, replacing CoStar Group Inc. Lumentum confirmed the addition on May 11, with Chief Executive Michael Hurlston calling it recognition of optics’ critical role in AI infrastructure as data-center speed and bandwidth rise. Shares jumped 16.6% that day. The company had also reported fiscal third-quarter revenue of $808.4 million, up 90.1% from a year earlier, and adjusted earnings of $2.37 a share.
