U.S. tech stocks rout deepens on AI spending fears and talent moves
On June 22-23, 2026, U.S. tech stocks suffered severe declines, led by Alphabet (down 6% after Nobel laureate John Jumper left Google DeepMind for Anthropic) and semiconductor stocks (Micron plunging 13%, Nvidia losing 4%). The Nasdaq fell over 2% as investors worried about excessive AI capital expenditure, high valuations, and potential Fed rate hikes. Contrast emerged between chipmakers receiving AI spending (Micron, which gained on an Anthropic deal) and hyperscalers footing the bill. SpaceX also slumped over 10% after its IPO.

Semiconductor Stocks Fall on Memory Cost Concerns
Semiconductor stocks retreated on Friday, June 26, 2026, led by sharp declines in memory and storage companies. Micron Technology fell over 6%, Sandisk dropped more than 10%, and Western Digital lost over 7%. The sell-off was driven by concerns that rising memory prices could squeeze margins across the broader tech industry and weigh on consumer demand. Apple and Microsoft have both raised prices on products to offset surging memory costs. Sentiment was further pressured by a New York Times report suggesting a potential delay to OpenAI's IPO until 2027, seen as a negative signal for the AI trade. Other chipmakers including Nvidia, AMD, Broadcom, Intel, Marvell, and Qualcomm also moved lower. Equipment makers Applied Materials and Lam Research each declined over 3%.
Yahoo FinanceWhy Tech Stocks Are Getting Hammered
Tech stocks experienced a significant sell-off on Tuesday, June 23, 2026, with the tech-heavy Nasdaq composite dropping roughly 2% and the S&P 500 falling over 1%. The decline was driven by investor skittishness over high valuations and geopolitical tensions, leading to doubts about whether massive spending on artificial intelligence (AI) infrastructure will yield returns. Major California tech companies including Nvidia, Qualcomm, Intel, and Marvell Technology saw share price drops, along with Meta, Apple, and Alphabet. Micron Technology plunged over 13% ahead of its earnings report. The sell-off was exacerbated by a spillover from Asian markets, where South Korean memory chip makers SK Hynix and Samsung Electronics fell over 12%. Analysts described the situation as a 'gut-check moment' for the AI boom, though AI adoption continues to grow. The previous day, SpaceX shares had plunged 16% after a record IPO but recovered slightly.
Yahoo FinanceNvidia, Micron, Alphabet lead tech sell-off as AI trade cools
On June 23, 2026, a broad tech sector sell-off led by Nvidia, Micron, and Alphabet drove the Nasdaq lower for a second consecutive session. Investors shifted to risk-off mode after the Federal Reserve signaled inflation remains too high, hinting at possible rate hikes. Micron dropped over 8% ahead of its earnings report. The sell-off extended to other AI-related stocks like AMD, Broadcom, and Intel. Concerns about the market's ability to absorb lofty valuations for AI companies were amplified by the massive SpaceX IPO and upcoming debuts from Anthropic and OpenAI. The tech sector had been the best-performing sector year-to-date but now faces a cooling AI trade.
Yahoo FinanceNvidia, Micron, AMD Lead Tech Sell-off as AI Trade Cools on Hawkish Fed Signals
On June 23, 2026, a broad tech sector sell-off occurred, led by AI and chip stocks Nvidia (NVDA), Micron Technology (MU), and AMD (AMD). The decline was triggered by a risk-off shift among investors following a hawkish Federal Reserve signaling that inflation remains too high, raising the possibility of future rate hikes. The Technology sector (XLK) dragged the Nasdaq Composite down about 2.1%, extending losses for a second session. Nvidia fell over 4%, while Micron tumbled 13% from record highs ahead of its earnings report. Alphabet also declined nearly 1%. Other chipmakers like Broadcom and Intel fell as well. The sell-off reflects cooling in the AI trade, which had been the best-performing sector year-to-date. Analysts cite concerns over lofty AI valuations amid the massive SpaceX IPO and expected IPOs of AI developers Anthropic and OpenAI, as well as the potential for further Fed tightening.
Yahoo FinanceChip stocks plunge, but bargain-hunters limit scale of tech rout
U.S. chip stocks fell sharply on June 23, 2026, reversing recent record highs, as the semiconductor index dropped 7.9% and the Nasdaq slid 2.2%. Micron Technology plunged 13% ahead of its earnings report, while Nvidia fell 4.1%, pushing its market cap below $5 trillion. Other chipmakers including Qualcomm (-8%) and Marvell (-9.4%) also suffered heavy losses, with memory chipmakers SanDisk (-14%) and Western Digital (-8.5%) hit hardest. Bargain-hunting tempered the broader selloff, and some tech giants like Microsoft rose 1.8%. The rout was driven by a highly concentrated, flow-driven market vulnerable to sentiment shifts, a challenging interest-rate backdrop, and concerns about AI investment returns. SpaceX briefly dipped below $2 trillion market cap before recovering. Analysts cautioned against viewing the drop as a buying opportunity, citing the stock's small public float. The Nasdaq is now down over 5% from its June 2 peak.
Yahoo FinanceU.S. tech megacaps slide as SpaceX extends slump, AI expense concerns grow
On June 22, 2026, shares of major U.S. technology companies declined sharply, driven by a third consecutive session of losses for SpaceX, which fell over 10% after its post-IPO rally. Alphabet dropped 6%, set to erase more than $256 billion in market value, following the departure of Nobel laureate John Jumper from Google DeepMind to AI startup Anthropic. Amazon fell 4.8%, while Meta Platforms and Microsoft each eased around 3%. The sell-off reflects growing investor anxiety over massive capital expenditures on AI infrastructure by hyperscalers, with limited evidence of returns. In contrast, chip-related stocks rose, led by Micron Technology, which gained 5.8% to record highs after announcing a strategic agreement with Anthropic. Analysts noted a market distinction between companies receiving AI-related investment checks (memory chipmakers) and those writing the checks.

Amazon lost 4.8%, while Meta and Microsoft each declined about 3%, collectively set to lose over $248 billion. Investors remain skeptical that AI products will generate sufficient returns to justify the heavy spending. In contrast, chip-related stocks rose, with Micron Technology gaining 5.8% to a record high after announcing a strategic agreement with Anthropic to scale next-generation AI infrastructure. Analysts noted a market divide between companies receiving AI spending (chip makers) and those writing the checks (hyperscalers).
