On Nov. 18, 2025, stocks plunged amid AI bubble concerns, pushing major U.S. indexes sharply lower as fear gauges fell and bitcoin weakened, while investors awaited Nvidia’s earnings and U.S. jobs data.

AI Valuation Stress and Market Impact

At 1:36 p.m. ET, the Dow Jones Industrial Average dropped 500 points, the S&P 500 declined about 0.8–1%, and the Nasdaq fell 1.1%, marking a fourth consecutive day of losses. Investor anxiety focused on whether leading AI companies, especially Nvidia, could sustain the rapid growth priced into their shares. Several prominent investors reduced exposure to AI stocks, intensifying selling pressure across the sector.

The selloff was worsened by the unwinding of crowded tech and AI trades and by thinner liquidity, which amplified price swings as positions were closed. Markets are closely watching Nvidia’s upcoming earnings and guidance as a gauge of the AI sector’s health; any sign of slowing demand or cautious outlook could further compress valuations.

Sentiment, Crypto, and Economic Data

The CNN Fear & Greed Index fell to 14 out of 100, signaling extreme fear and marking its lowest reading since spring 2025. The CBOE Volatility Index (VIX), a measure of market risk, rose nearly 20% in the prior week, reinforcing a risk-off tone.

Bitcoin dropped below $92,000, erasing its year-to-date gains and hitting a seven-month low, which contributed to broader market caution. Investors awaited key U.S. economic releases, including the next nonfarm payrolls report and Walmart’s earnings, after recent disruptions such as a government shutdown and higher tariffs clouded economic signals. Analysts outlined three scenarios tied to these events: continued volatility with potential stabilization if earnings and macro data hold; further declines if AI or retail disappoint; and recovery if AI demand and consumer spending remain strong.
