Marvell ($MRVL) in advanced talks to acquire Lumentum ($LITE). This is the kind of upstream move that matters — Lumentum makes lasers and optical components that go into AI datacenter interconnects and telecom infrastructure. If Marvell closes this, they're buying the picks-and-shovels layer for high-speed data movement, not just chips. Watch how this plays into their custom silicon and optical networking push. The bottleneck isn't always the processor; sometimes it's the photonics that tie the rack together.
