Rising 1.6T switching demand favors optical suppliers, though their execution risks vary. Bank of America says the market could grow ~101% annually through 2030. Marvell's leading DSPs and Lumentum's supply-short 200G EML lasers are lowest risk; Applied Optoelectronics' capacity expansion and Fabrinet's customer concentration make them medium risk. Aeluma remains pre-commercial, while Lightwave Logic's polymer modulators are a high-risk moonshot despite its TSM partnership. x.com 

Marvell risks paying a peak-scarcity price for Lumentum if optical supply catches up by 2028-30. The proposed ~$99B deal values Lumentum at roughly 20x guided annualized revenue and 58x estimated after-tax operating income, while Lumentum, Coherent and Chinese suppliers are adding laser capacity. The DSP-and-laser combination has strategic logic, but durable scarcity economics and Nvidia's response remain uncertain. x.com 

Broadcom's Jalapeño chip deal with OpenAI is already priced in and margin dilutive. OpenAI guides to about 30 GW by 2030; at 30-40% Jalapeño, that is 9-12 GW, matching the 10 GW deal signed in October 2025. Selling finished chips, Broadcom books full ASPs but fronts wafers, HBM and other costs, about $15 billion per GW or $25-45 billion a year, at 50-60% margins at best. FY27 guidance already tops $100 billion; the bull case is maybe $120 billion. Broadcom even lends OpenAI the build money. … Show more

Broadcom's integrated optics, electronics and packaging could lower custom-chip system costs because separate suppliers defend their margins. At similar valuations, it is preferred to Nvidia and has more room to beat expectations. Google TPU v8 shipments are estimated at 4.0M in 2026 and 9.1M in 2027, assuming Broadcom supplies the remainder after MediaTek's allocation. Anthropic financing adds value only if chip profit exceeds likely support payments and capacity costs. x.com  x.com 

Tighter Lumentum laser allocations would strengthen Coherent's pricing power if Marvell's rumored acquisition leads it to prioritize Nvidia and its own modules. Other buyers would face tighter supply, and hyperscalers would push harder to second-source lasers from Coherent. x.com 

ASIC design is a race to the bottom, very bearish for Broadcom, MediaTek and Marvell as more leading-edge wafer capacity comes online from TSMC, Intel and Samsung. Google sources IP and swaps vendors constantly, showing the design houses add little differentiated value, transceivers aside. AMD, Apple and Nvidia do not outsource because it dilutes margins and most IP is one-size-fits-all. At scale, wafer allocation is the real constraint; the shift may take a year or two. x.com  x.com 

Optics and photonics should be among AI's biggest winners as faster GPU networks need optical connections that suppliers cannot expand quickly enough. Lumentum says some components are sold out through early 2029; Sivers is investing $30M to target more than 100M lasers a year, with operations expected in Q4 2027. Potential US restrictions on Chinese transceivers could reshape supply in 2027. Applied Optoelectronics and Sivers are the favorites. x.com  x.com 

AI infrastructure bottlenecks could give eight stocks as much as 18x upside. Nvidia supplies frontier-model GPUs; Broadcom and Marvell supply custom silicon and networking; TSMC makes advanced chips; Micron supplies sold-out HBM; Vertiv provides power and cooling; Palantir monetizes enterprise AI; Alphabet spans TPUs, research, cloud and apps. The list tracks where AI infrastructure spending is flowing. x.com  x.com 

Broadcom's AI business is smaller and growing slower than Nvidia's networking unit alone, yet Broadcom is valued at $2.269T against Nvidia's $5.201T. Broadcom's Q2 AI semiconductor revenue rose 143% to $10.8B, with Q3 guided to $16.0B, while Nvidia's data-center networking revenue rose 199% to $14.8B. Hock Tan also said Google is diversifying away from Broadcom, and a Fubon roadmap shows Google using MediaTek for some TPUs. x.com  x.com 

A potential Lumentum acquisition could let Marvell pair custom AI chips with the optical infrastructure connecting them. Following Celestial AI, it could become one of the few companies offering both, moving toward an AI-focused version of Broadcom; financing a deal this large remains a major concern. x.com
