AI chip rally adds $2T to Micron, Intel, AMD
Chip stocks outside Nvidia surged in Q2 2026 as investors broadened AI exposure to memory and CPU suppliers. Micron rose more than 240%, Intel jumped 216% and AMD climbed 186%, together adding about $2 trillion to their combined market capitalization. Micron reported a more-than-fourfold revenue increase for the latest quarter and a jump in gross margin to 84.9%. Other AI infrastructure suppliers also posted large gains — Marvell, Arm and the VanEck Semiconductor ETF saw double- and triple-digit returns — while hyperscalers such as Alphabet, Meta, Amazon and Microsoft had mixed results. Barclays analyst Anshul Gupta attributed the moves to a rotation from AI hyperscalers into broader semiconductor ‘AI enablers.’
Broad market rotation into AI-related semiconductors signals wider industry capitalization and potential shifts in AI infrastructure spending and supply-chain demand, affecting tech suppliers and investors.

Wall Street Shifts AI Chip Favor to Intel, AMD, Micron
Wall Street investors have rotated AI hardware bets away from Nvidia toward CPU, memory and optical-component suppliers such as Intel, AMD, Micron and Corning. The move follows growing demand for CPUs and memory as AI use cases shift from chatbots to agent-style workloads, boosting data-center component needs. This week AMD and Intel each rose roughly 25%, Micron jumped more than 37% (and is up ~750% over the past year with market capitalization above $800 billion), and Corning climbed about 18%. Analysts and banks — including Mizuho, Goldman Sachs, Bernstein and JPMorgan — pointed to CPU and memory tailwinds, while deals and partnerships (Nvidia’s investment rights in Corning and reported Intel–Apple chip talks) also influenced market moves.
Micron Stock Surges on Memory Chip Rally
Micron Technology's shares jumped sharply in early May 2026 as a global memory-chip shortage and rising demand tied to the AI buildout pushed semiconductor stocks higher. Micron rose more than 15% on Friday, gained nearly 38% for the week and has climbed about 84% over the past month, lifting its market capitalization above $840 billion, per LSEG. The rally reflects broader strength across chipmakers including AMD, Intel, Samsung and SK Hynix, and is driven by hyperscaler capital expenditures boosting demand for DRAM, NAND, CPUs and storage. Analysts and research firms cited widening prices and margins for memory makers and increased retail investor interest in Micron as contributors to the move.
AI Rally Sends SK Hynix and Samsung Stocks Higher
South Korean chipmakers SK Hynix and Samsung Electronics surged more than 20% on July 30, 2026, as a rebound in U.S. technology stocks followed stronger-than-expected quarterly results from Amazon and Microsoft that revived optimism about AI infrastructure spending. The iShares Semiconductor ETF also jumped overnight, and Japanese semiconductor names such as Advantest, Tokyo Electron, Disco, Lasertec and Renesas Electronics rallied. Market commentary cited Microsoft’s Azure cloud strength and controlled capex as catalysts for renewed risk-on appetite toward AI-linked chipmakers.
