Shares of Micron, Intel, and AMD chip companies surged as AI investment pushed the market value up by an additional $2 trillion.

Investors are shifting funds from tech giants to chip manufacturers, boosting Micron, Intel, and AMD in Q2 and increasing their combined market capitalization by approximately $2 trillion amid expanding global investment in AI and data centers.

On July 1, 2569 at 05.26:XNUMX p.m., CNBC news agency reported that Although Nvidia still holds the position of the world's most valuable company by market capitalization and continues to grow driven by artificial intelligence (AI), in the second quarter of 2026, the standout performers were other chip manufacturers, with Micron Technology, Intel, and Advanced Micro Devices (AMD) all experiencing strong gains. As a result, the combined market value of the three companies increased by approximately $2 trillion in the past quarter.

Currently, these three companies have risen to become the 10th, 11th, and 12th most valuable technology companies in the United States, respectively, reflecting the diversification of investment from large AI stocks to companies in the semiconductor supply chain.

Although Nvidia still reported strong revenue growth, its share price rose only 15% in the second quarter. Meanwhile, major cloud service providers (hyperscalers) that are Nvidia's main customers—Amazon, Alphabet, Meta, and Microsoft—had more varied share price performance. Alphabet gained the most at 24%, while Meta fell nearly 2%, representing the weakest performance in the group.

Anshul Gupta, an analyst from Barclays. It was noted that investors are shifting their investments from hyperscaler stocks to companies that support the AI ​​ecosystem (AI enablers), particularly in the semiconductor sector, resulting in significant gains for several chip stocks.

Shares of Micron Technology, one of the world's largest memory manufacturers, surged more than 240% in the second quarter, boosting its market value to approximately $920 billion. This followed the company's report of more than fourfold revenue growth in its latest quarter, driven by higher memory chip prices due to increased demand from AI chip manufacturers. Meanwhile, its gross margin jumped to 84.9% from 39% in the same period last year.

Intel's share price soared 216% in a single quarter, adding more than $480,000 billion to its market value. The company was boosted by ongoing construction of chip manufacturing plants in the United States and a recovery in demand for central processing units (CPUs) as AI is increasingly being used for end-user processing.

While AMD, Intel's main competitor, saw its market value increase by approximately $615 billion after its share price nearly tripled, its graphics processing (GPU) business still lags far behind Nvidia in market share.

Analysts believe that market movements in the past quarter may reflect a new leadership shift in the AI ​​theme, with investors increasingly investing in chip manufacturers and technologies that complement Nvidia's ecosystem, rather than solely in companies that are AI users. They also predict that massive investment in AI data centers worldwide will drive growth for companies across the broader semiconductor industry supply chain.

Besides memory and CPU manufacturers, other AI infrastructure companies also benefited. Shares of Marvell Technology, a manufacturer of networking equipment for data centers, surged approximately 200%, while shares of Arm Holdings, a developer of chip technology and architecture, rose 134% in a single quarter.

The VanEck Semiconductor ETF (SMH), which invests in semiconductor stocks, rose 71% in the second quarter, marking its best quarterly return since it began trading in 2000. This reflects the continued strong investment trend in the chip industry driven by the expansion of AI technology.
