🎙️ 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? This episode is presented by @CrusoeAI.

Intel Plunges 23% as PC Weakness and Supply Snags Crush Outlook Austin: Bummed to continue to hear Intel unable to keep up with server CPU demand, this has been going on for many quarters. And the other side of the products business seemingly has too much supply into a down client market (due to memory prices, which we’ve known for a long time that memory would hurt client).

Nvidia Weighs Credit Guarantees to Back Nscale’s Anthropic Compute Deal Vik: If NeoCloud (like NScale) isn't getting enough customers, what benefit is there in NVIDIA stepping in, purchasing compute, and renting it back? It's just more bandaid measures. Austin: I disagree, I think broadly neoclouds are helpful and necessary but access to capital is hard, and like a parent cosigning a mortgage with their first-time homebuying child, Nvidia can help neos get past bank headaches.
