AI summary

What happened, with direct paths to the underlying reporting

AI infrastructure momentum has lifted Lumentum as data-center fiber connectivity growth accelerates. OpenAI's near-$70B recurring revenue run rate and a $84.5B Anthropic–SpaceX compute deal underscore the scale of AI workloads, while AMD’s $8.2B World Labs acquisition signals broader hardware capex. These forces point to sustained optical transceiver demand and multi-year order visibility for LITE.
