Custom-silicon duopoly with AVGO

AI supply-chain thesis — mapping bottlenecks, focus companies, and supply-chain exposure for investors.

**Bottleneck theme:** Custom Silicon **Focus:** $MRVL — Marvell Technology, Inc. Marvell is the smaller half of the custom-silicon duopoly with $AVGO. Management has disclosed 18 active custom-silicon programs across hyperscaler and AI-accelerator customers, with the Trainium2 / Maia / Microsoft AI infrastructure programs expected to ramp through 2026-2027. Beyond custom ASICs, Marvell holds franchise positions in coherent DSPs (1.6T optical), automotive Ethernet, and storage controllers — diversification that has historically supported through-cycle margin even as the AI mix builds. The investment case is custom-silicon program ramps materially lifting AI revenue mix, plus optical-DSP share gains as 1.6T deploys. The bear case is execution risk on multiple concurrent tape-outs, customer concentration (one or two hyperscaler programs drive disproportionate growth), and AVGO competitive intensity at the high end. Pair with $AVGO (the duopoly leader) and $ALAB (the retimer + scale-up adjacent name).
