Micron, Intel, AMD Add $2 Trillion — AI Chips Power Surge
By John Nada·Jun 30, 2026·2 min read
Semiconductors soared by $2 trillion, driven by AI investments. Micron, Intel, and AMD lead as investors shift focus from AI hyperscalers.
In a stunning twist, the semiconductor industry has witnessed a staggering $2 trillion surge in market capitalization, spearheaded by Micron, Intel, and AMD in the second quarter. These chipmakers not named Nvidia have skyrocketed in value as investors broaden their artificial intelligence portfolios. According to CNBC Business, Micron and Intel more than tripled in value, with AMD not far behind, positioning these companies as the 10th, 11th, and 12th most valuable U.S. tech firms.
What's behind this mammoth leap? A strategic rotation from AI hyperscalers to AI enablers, driving investor enthusiasm into the semiconductor sector. Barclays analyst Anshul Gupta notes this shift as a key factor. Micron, for instance, witnessed its market cap swell by roughly $920 billion, spurred by soaring memory prices from AI chipmakers. Revenue more than quadrupled in the latest quarter, with a remarkable jump in gross margin to 84.9% from last year's 39%.
Intel, traditionally a CPU powerhouse, added $480 billion to its market cap. Renewed demand for CPUs, especially with AI migrating to devices, alongside its U.S. factory expansions, has paid off handsomely. Meanwhile, AMD's nearly tripled stock price has boosted its value by $615 billion, despite lagging in the GPU race against Nvidia.

Beyond these giants, other sectors of AI infrastructure, like networking and chip design, saw significant gains. Marvell's networking gear soared about 200%, and Arm's chip design surged 134% in the quarter. The VanEck Semiconductor ETF (SMH) echoed this enthusiasm, climbing 71% — its best quarterly performance since its inception in 2000.
Yet, amid all this growth, it's worth noting Nvidia's more modest 15% rise despite its dominance. Its hyperscaler customers, including Amazon and Meta, posted mixed results, with Meta even seeing a 2% decline. However, Alphabet led this pack with a 24% gain, hinting at a more nuanced landscape for AI investments.
This reshuffling in the semiconductor hierarchy suggests a potential shift in AI infrastructure focus. Investors are clearly betting on a broader spectrum of companies poised to capitalize on the anticipated expansion of AI data centers. This isn't just about the now; it's a glimpse into a future where AI infrastructure underpins a wider array of tech advancements.
