The artificial intelligence boom is rapidly expanding beyond Nvidia. Investors are now pouring capital into the companies powering the next phase of AI infrastructure – especially memory and semiconductor manufacturers.
In a historic 24-hour stretch, U.S. memory giant Micron Technology (MU) and South Korea’s SK Hynix both crossed the $1 trillion market capitalization mark for the first time, highlighting how aggressively Wall Street is revaluing AI-linked hardware companies.
As global tech indices climb to fresh highs, the market’s focus is shifting toward advanced memory solutions, CPUs, and the broader semiconductor supply chain supporting next-generation AI workloads.
Micron Stock Surges 19% After Major UBS Price Target Increase
Micron shares surged after UBS nearly tripled its price target on the company from $535 to $1,625 per share, citing explosive demand for high-bandwidth memory (HBM) used in artificial intelligence systems.
The rally briefly pushed Micron above a $1 trillion market valuation for the first time on Tuesday.
According to UBS, the new valuation reflects long-term supply agreements and partially fixed pricing structures that could fundamentally reshape the memory market.
The bank wrote:
“We believe the market will start to put a more ‘normal’ multiple on the stock and MU will continue to re-rate higher as more details emerge about the structural changes AI has driven to the entire memory complex.”
The revised target implies that Micron shares could more than double from their previous Friday close. Just weeks ago, the company surpassed a $700 billion market capitalization milestone. Year to date, the stock has more than tripled.
SK Hynix Extends Global AI Chip Rally
The semiconductor rally is not limited to the United States.
Shares of South Korea’s SK Hynix jumped sharply on Wednesday, lifting the company above the $1 trillion valuation threshold for the first time. The stock has now gained roughly 250% since the start of the year, helping drive South Korea’s KOSPI index to record highs.
The primary driver behind these gains is an intensifying global memory shortage.
Demand for hardware capable of supporting “agentic AI” systems continues to outpace supply, leaving manufacturers struggling to meet orders. The imbalance has significantly strengthened pricing power for major memory producers including Micron, SK Hynix, and Samsung.
AI Chip Rally Broadens Beyond Nvidia
The latest phase of the AI trade is now spreading across the broader semiconductor industry.
Intel
After lagging during the early stages of the AI boom, Intel shares have rallied more than sixfold and are trading near all-time highs. The company continues to execute a major turnaround strategy supported by significant U.S. government investment.
Qualcomm, AMD, and Marvell Technology
Qualcomm, AMD, and Marvell Technology have also benefited from rising AI infrastructure spending, with all three stocks reaching fresh record highs as investors rotate into broader semiconductor exposure.
Macro Environment: Global Tech and Market Trends
The semiconductor rally comes alongside several major macroeconomic developments across global markets.
China’s Industrial Earnings Accelerate
China’s industrial profits rose 24.7% in April, marking the fastest pace of growth since November 2023.
Profits in computing and electronics manufacturing nearly doubled year over year, reinforcing optimism around global technology demand. Meanwhile, a survey from the European Union Chamber of Commerce showed that many European companies continue expanding their Chinese supply chains despite ongoing geopolitical de-risking efforts.
Market Outlook for AI Semiconductor Stocks
Global investors continue balancing strong corporate earnings and accelerating AI adoption against broader macroeconomic and geopolitical risks.
Japan and South Korea remain near record highs, while markets continue monitoring U.S.-Iran ceasefire negotiations and regional tensions. Following another record close for the S&P 500 on Tuesday, U.S. stock futures remain relatively stable, signaling a highly selective and data-driven trading environment.
The broader trend, however, remains clear: investors are increasingly betting that advanced memory and semiconductor infrastructure will become one of the biggest long-term winners of the AI economy.
