Memory and Optics Supply Chains Fracture: DDR5 Patent Fight Hits AI Server Builders as Indium Phosphide Prices Spike
Super Micro and Dell retreat on intellectual-property risk in the DDR5 stack while AXT, Coherent and Lumentum rally on compound-semiconductor pricing power, and Western Digital jumps on a White House policy tailwind.
The AI hardware complex is splitting along supply-chain lines. A DDR5 patent dispute is pressuring server assemblers Super Micro (-4%) and Dell (-3%), while upstream component and materials suppliers are capturing value: indium phosphide price hikes lifted AXT, Coherent and Lumentum, and storage names Western Digital and SanDisk extended a re-rating on policy and pricing catalysts. The message for allocators is that margin power is migrating from integrators to constrained input owners.
