On Tuesday, June 23, 2026, Wall Street experienced a substantial selloff in technology stocks, specifically those tied to artificial intelligence, triggering fears that the AI market might be an overblown bubble. This "chip-wreck" saw the Nasdaq 100 drop by 3.3% and a closely watched index of chipmakers slide about 8%. Losses were even more pronounced in Asia, with South Korea's Kospi plummeting 10% from its record high. This rout marked a moment of caution, with some analysts noting signs of a potential bubble.
The decline was fueled by concerns over the immense capital expenditure flowing into AI infrastructure and semiconductor capacity expansion. Major tech companies like Alphabet, Amazon, Meta Platforms, and Microsoft are projected to spend up to $720 billion this year, primarily on AI data centers. Critics are questioning whether AI can generate the necessary profits and productivity to justify such massive investments, especially given that a 2025 MIT study found approximately 95% of businesses investing in AI had yet to monetize the technology, with a combined investment of roughly $40 billion.
Specific companies were hit hard, with Micron Technology's shares tumbling over 13% ahead of its earnings release, and SanDisk also falling by about 13%. Nvidia, a leader in AI chips, saw its value drop 3%, while Intel and Advanced Micro Devices were both down around 6%. The Philadelphia Semiconductor Index plunged 7.9%. Analysts like Brock Weimer of Edward Jones suggested the pullback might be largely profit-taking after strong market rallies, while Philip Straehl of Morningstar Wealth warned that elevated capital investments historically haven't translated into strong outcomes for investors, potentially leading to oversupply and weighing on pricing for semiconductor companies. Investor sentiment was further impacted by expectations of a more aggressive interest rate hike by the Federal Reserve.
The market's volatility on Tuesday prompted a rotation into more defensive sectors, with consumer staples emerging as the strongest performer in the S&P 500, rising 1.8%. The CBOE Volatility Index, Wall Street's "fear gauge," climbed to 19.52, its highest in over a week, reflecting heightened market uncertainty. Despite the sharp decline, some analysts, such as Dan Ives of Wedbush, viewed this as another "gut-check moment" in the ongoing AI revolution rather than a dramatic shift in sentiment, noting that chipmakers' shares still stand well above their prices at the beginning of the year.
