We had a really fun chat with @aschmitt and @ScottWilkinsonQ from @CignalAI about what the potential Marvell + Lumentum deal would actually mean.
These guys are long time industry veterans and their inputs were very insightful.
We called them on the show just 30mins before recording time and they graciously joined.
Takes are not prepared, it’s fully off the cuff… it’s like a reaction video with no fluff.
Check it out!!

🎙️ NEW EPISODE: Why Marvell Wants Lumentum: Vertical Integration in AI Optics With Cignal AI
Recorded the morning after the $MRVL $LITE rumor broke. Our thoughts (live with no prep!)
Andrew Schmitt and Scott Wilkinson of market research firm Cignal AI join Austin and Vik to break down Marvell's potential acquisition of Lumentum. They explain how Marvell could run the "Broadcom playbook" by bundling DSPs and optics, even at the cost of competing with its own customers.
- The driver is vertical integration, not securing laser capacity. Marvell wants to control the supply chain from chips to optics to co-design better products for AI
- Marvell's DSP customers would have to compete with a vertically integrated Marvell-Lumentum, a dynamic that has already pushed some players out of coherent
- Lumentum's Optical Circuit Switches (OCS) and high-power lasers for CPO and NPO matter as much as its current-gen transceivers
- After a 4x expansion of its Indium Phosphide fab, Lumentum can supply Marvell AND keep selling lasers to the open market
- A bidding war is possible. Could the leak be intentional, to attract suitors?
