Micron Technology’s stock fell nearly 10% to $739 on July 29, extending a brutal month-long selloff in memory chip makers as investors reassess the outlook for the trillion-dollar semiconductor industry.
The decline came amid a deepening global chip sector rout that has wiped billions from memory makers’ valuations, despite record earnings growth driven by artificial intelligence demand. The selloff reflects growing anxiety about whether the memory chip boom can sustain current price levels as new competitors emerge and supply constraints ease.
Chinese memory chipmaker CXMT surged 466% in its Shanghai debut on July 27, becoming mainland China’s most valuable listed company and signaling a major new competitor for Micron, Samsung, and SK Hynix. According to CXMT’s IPO prospectus, the company held about 7.7% of the global DRAM market in 2025, making it the world’s fourth-largest memory chip maker. The blockbuster IPO raised $8.6 billion and gave CXMT a war chest to expand capacity and challenge established players.
SK Hynix, the world’s second-largest memory chip maker, reported record Q2 2026 results with operating profit surging 557% year-over-year to roughly $42 billion. Yet the company’s stock fell approximately 10% despite the earnings beat, signaling investor concern about peak pricing. SK Hynix’s revenue of 79 trillion Korean won fell short of Wall Street’s expectations of 84 trillion won, prompting analysts to lower their 2026-2028 revenue forecasts. The company maintained its bullish outlook for the second half of 2026, citing tight supply and strong AI memory demand, but the market’s reaction suggested investors are bracing for a deceleration in memory chip prices.
The broader semiconductor sector has been in retreat since mid-July, with the Philadelphia Semiconductor Index and major chip stocks declining sharply. Analysts point to a confluence of concerns: the prospect of memory chip oversupply as new capacity comes online, China’s advancing chipmaking capabilities, and questions about whether AI spending will sustain the extraordinary price premiums that have defined 2026. Bloomberg Intelligence’s Shuli Ren argued in early July that the global memory shortage peaked in Q2 2026 and could tip into oversupply by 2028, a scenario that would pressure margins across the industry.
Micron has been among the hardest hit, with its stock down roughly 30% from its all-time high earlier in the month despite reporting blockbuster fiscal Q1 2026 results in July that beat revenue and earnings guidance by 24% and 31%, respectively. The company’s valuation reset reflects the market’s pivot from celebrating record profitability to pricing in a potential shift toward a more competitive, lower-margin memory market. Analysts remain broadly bullish on Micron longer-term, with an average price target around $1,542, but near-term volatility is likely as the sector digests the implications of new competition and moderating memory prices.
