Key Points:
- Investors are buying shares of Intel, AMD, Micron, and Corning as the tech hardware boom expands past Nvidia.
- Micron crossed the $800 billion market cap threshold due to a massive global memory chip shortage.
- The data center CPU market could surge from $27 billion in 2025 to $60 billion by 2030.
- Analysts warn that the current semiconductor rally looks like the 1999 internet bubble and predict a 30% market crash.
Since late 2022, Nvidia has completely controlled the artificial intelligence stock market boom. The massive chipmaker still expects to grow its revenue by 70% this year. However, Wall Street investors are now moving their money into other hardware companies. They see huge potential in businesses that sat quietly in the background during the first few years of the massive technology rush.
This past week showed exactly how much the market is shifting. Analyst Jordan Klein called the current trend a complete changing of the guard in the tech sector. Chipmakers Advanced Micro Devices and Intel saw their stock prices jump about 25%. Memory chip producer Micron surged more than 37%. Fiber-optic cable manufacturer Corning also climbed 18%.
All four of these tech companies more than doubled in value this year alone. Intel led the group by soaring well over 200%. Meanwhile, Nvidia barely beat the wider market. Nvidia gained only 15% so far in 2026, and that number includes an 8% rally just this week. Investors clearly believe data centers will need many different advanced parts for years to come, so they are spreading their bets across the entire hardware industry.
Computer memory stands out as the biggest recent market theme. A massive global shortage drove prices sky-high and turned Micron into a superstar. Micron spent 47 years working in a quiet corner of the semiconductor world. Now, the company boasts a market value above $800 billion after jumping 750% over the last year. CEO Sanjay Mehrotra admitted in March that key buyers receive only 50% to 66% of the chips they ordered.
Micron controls most of the memory market, alongside two South Korean companies, Samsung and SK Hynix. Both foreign firms also enjoy massive stock rallies right now. Klein explained to his clients that companies make incredible profits when a market hits a severe shortage. When demand outruns supply, prices shoot up while operating expenses barely rise. Suppliers simply cannot build new factories fast enough to meet the flood of new orders.
Beyond memory chips, tech giants desperately need central processing units. Every day, computers and smartphones rely on these CPUs to function properly. Early in the boom, companies like Google, Microsoft, and Amazon ignored CPUs so they could buy up all of Nvidia’s graphics chips. Now, the momentum is shifting from simple chatbots to complex digital assistants. Bank of America predicts the data center CPU market will more than double, jumping from $27 billion in 2025 to $60 billion by 2030.
AMD proved this trend is real when it released its quarterly earnings this week. The company crushed Wall Street estimates, driven by massive growth in data center sales. AMD CEO Lisa Su told investors her company now expects 35% growth in the server CPU market over the next three to five years. Just last November, the company predicted only 18% growth. Su noted that new digital agents drive tremendous demand across the entire tech industry.
Intel also sits in the middle of a massive revival. For years, Intel missed out on major tech shifts, especially in early artificial intelligence. A huge investment from the federal government last year finally turned things around. Intel saw its stock price more than double in April, marking its best month in history. The shares kept climbing in early May, surging 13% on Tuesday after reports emerged that Apple wants Intel to build processors for its devices. By Friday, the stock jumped another 14% after reporters confirmed that the two giants had reached a manufacturing agreement.
Other companies benefit directly from working closely with Nvidia. Corning, a 175-year-old glass manufacturer, signed a massive deal with Nvidia on Wednesday. Corning will build three new American factories dedicated entirely to optical tech for the giant chipmaker. This deal allows Nvidia to invest up to $3.2 billion directly into Corning. Nvidia plans to replace slow copper cables with fast fiber-optic cords as it builds massive new computing systems.
This new deal adds to Corning’s massive pipeline of work. Earlier this year, Corning signed a $6 billion contract to supply fiber-optic cables to Meta data centers through 2030. Nvidia CEO Jensen Huang recently noted that the global economy is undergoing the largest infrastructure buildout in human history. Corning’s stock broke its dot-com-era record in February and continues to climb every month.
While tech investors celebrate these massive gains, some analysts warn the party will end poorly. Market experts see many uncomfortable similarities to the late 1990s internet boom, which ended in a devastating market crash. Jonathan Krinsky, an analyst at BTIG, recently sent a stark warning to his clients. He predicted a massive 25% to 30% crash for the main semiconductor market index, which already climbed 66% this year. He warned investors that the current market frenzy actually looks more extreme than the famous dot-com bubble.
