The intensifying global shortage of memory chips, fueled by the artificial intelligence expansion, is creating a growing divergence in corporate earnings and stock market returns.

Memory manufacturers Micron Technology Inc. and Samsung Electronics Co. have seen their shares reach all-time highs, propelled by stellar financial results driven by robust product pricing. Conversely, consumer product companies ranging from HP Inc. to Nintendo Co. are facing profit pressures due to elevated semiconductor costs.

This supply constraint highlights how AI is transforming the semiconductor cycle, elevating memory from a basic commodity to a critical bottleneck. This shift has made pricing power the key differentiator in global markets: suppliers are reaping extraordinary profits, while device manufacturers grapple with increased expenses and compressed margins.

The severity of the situation is evident in recent corporate disclosures. Memory pricing has been referenced over 550 times in earnings calls and quarterly reports this year—already surpassing the total mentions for any full year since 1999, according to data tracking global equities.

“It’s becoming increasingly clear that the memory shortage is not only more severe than anticipated but also likely to be more protracted than initially expected,” said Michael Brown, a senior research strategist. “With AI demand showing no signs of abating, insights from industry sources suggest this crunch could persist in some form potentially until 2030.”

Intensifying Challenges

The difficulties for memory-chip buyers are extensive. Nintendo's stock declined after it cautioned that high memory costs would erode margins on its gaming consoles, contributing to a year-to-date drop of over 30%. Shares of smartphone and electric vehicle manufacturer Xiaomi Corp. have fallen 20% in 2026, while copier and camera company Canon Inc. is down 10% on related concerns.

An increasing number of manufacturers are turning to price hikes to protect profitability, even if it risks dampening consumer demand. Following recent price increases for Microsoft Corp.’s Xbox and Sony Group Corp.’s PlayStation 5, Nintendo stated it will raise prices for its Switch 2. Meta Platforms Inc. is also increasing prices for its virtual-reality headsets.

“The severity of the impact depends on two key factors: the proportion of memory in a company's cost structure and its ability to secure supply or pass on costs to customers,” said Fabien Yip, a market analyst. She identifies high risk for smartphone and gaming console sectors, with medium risk for PC makers and large-scale cloud providers.

The outlook is markedly more positive for memory producers, who are capitalizing on soaring chip prices driven by relentless demand. An index tracking memory stocks has surged approximately 120% this year, while a measure of consumer electronics shares has risen only about 3%.

Samsung recently entered the exclusive group of companies with a market capitalization exceeding $1 trillion, following the announcement of a 48-fold increase in quarterly chip division profits last month. Fellow high-bandwidth memory producers Micron and SK Hynix Inc. have also sustained stock price advances after reporting strong results.

Expanding Advantage

The circle of beneficiaries is widening as AI applications progress from the training phase to broader, mainstream use. Investors are now actively acquiring shares of companies producing less-advanced DRAM chips, as well as various flash memory and hard-disk drive products.

Sandisk Corp. has extended its year-to-date gain to over 500% after stronger-than-anticipated earnings, driven by higher NAND prices. Shares of its partner, Kioxia Holdings Corp., are up more than 360% for the year ahead of its scheduled report.

The sustained AI-driven market rally has sparked some discussion of a potential bubble, particularly against a backdrop of economic uncertainty. Chip stocks experienced a decline as rapid recent gains prompted concerns about market overheating.

Proponents of the memory sector contend that AI has triggered a "supercycle" for chip demand, fundamentally altering the industry's traditional cyclical pattern. Contract prices for NAND chips have skyrocketed over 600% since late September, while DRAM chip prices have climbed nearly 400%, with analysts forecasting the trend to continue.

“Upward pricing momentum is expected to continue as AI-driven demand persistently outpaces supply, inventories remain constrained, and HBM supply is committed under multi-quarter agreements,” wrote strategists in a recent note. They added that prices and sales volumes could continue to rise through 2027-2028.
