The Nasdaq Composite fell 0.76% on Monday, August 24, 2026, declining 200.26 points to close at 25,980.19, as technology stocks slid on mounting investor concerns about artificial intelligence spending and valuations in the sector.
The tech-heavy index underperformed the broader market, where the S&P 500 dipped 0.28% and the Dow Jones Industrial Average gained 0.26%. Chip stocks led the decline, dragging down semiconductor and semiconductor-equipment companies as investors reassessed whether the massive capital outlays on AI infrastructure will generate sufficient returns.
The August 24 selloff reflects an ongoing tension that has gripped technology markets throughout 2026. Since early June, when the Nasdaq fell 4% in a single session driven by chip-stock weakness, investors have grappled with the scale of AI investment relative to near-term profitability. Major technology companies—Alphabet, Amazon, Meta, and Microsoft—are projected to spend more than $700 billion on capital expenditure this year, a jump of over 75% compared to the previous year, according to ratings agency Fitch.
Fitch warned in late July that the AI boom and the risk of a market correction represent major global credit risks. The ratings firm noted that the U.S. S&P 500’s cyclically adjusted price-to-earnings ratio has climbed to levels comparable to the late-1990s dotcom boom, while corporate bond issuance surged 26% in the first half of 2026, driven largely by AI-related fundraising. Fitch stated that uncertainty over future AI revenues, regulation, competition, and labor-market disruption could trigger a potentially significant and prolonged market correction with widespread macroeconomic implications.
The August 24 decline also coincided with broader geopolitical concerns. Investors have weighed tensions in the Middle East and their potential impact on oil prices and bond yields, factors that can pressure technology valuations. Earlier in the month, a broader tech selloff affected the S&P 500 on similar concerns, highlighting how multiple forces—from trade tensions to interest-rate expectations—combine to pressure the sector.
Chip stocks, which have been at the center of the AI investment narrative, remain particularly sensitive to sentiment shifts. In August, Broadcom fell 6% on AI financing concerns, exemplifying how individual company results and forward guidance interact with macro concerns. The broader question animating recent volatility is whether companies will achieve returns on their AI capital spending that justify the investments—a concern that has only intensified as spending accelerates.
Market participants have also heeded warnings about valuation levels. In late August, investor warnings about record-high valuations and investor behavior underscored the tension between the long-term potential of AI and near-term price risk. The Nasdaq’s 0.76% decline on August 24 is modest by recent standards, but it reflects the persistent caution that has characterized the sector since June.
