Rivian jumps as Nvidia, Intel and Pinterest fall: AI fears shake US stock market
Rivian Automotive surged 24% on strong earnings and higher 2026 delivery guidance, while Nvidia and Intel slipped amid AI-related uncertainty. Pinterest fell over 20% after missing revenue targets, whereas Palantir Technologies gained on AI-supporting services. Despite cooling US inflation, markets remain volatile as investors weigh growth clarity against AI disruption and uneven tech sector performance.
Rivian stock
Rivian Automotive surged to $17.38, gaining 24% in one day. The electric vehicle maker expects to deliver between 62,000 and 67,000 vehicles in 2026, which is nearly 50% more than last year. Its Q4 loss was 54 cents per share, smaller than the expected 68 cents. Revenue came in at $1.29 billion, slightly above the $1.26 billion forecast. Investors welcomed the clear guidance and stronger performance.
Shares of Nvidia and Intel
Shares of Nvidia, a top AI chip maker, fell 0.75% to $185.53. Investors are cautious about AI spending limits, competition, and potential margin pressures. Intel slipped 0.88% to $46.07. The semiconductor sector is seeing uneven performance. While some companies, like Applied Materials, gained on strong demand, others face challenges in competition and profits. Investors are distinguishing between firms that lead in AI and those still struggling.
Pinterest vs Palantir
Pinterest dropped 20.63% to $14.71. The company missed Q4 revenue expectations and gave weak guidance. Investors are concerned that AI may hurt Pinterest’s advertising and content model. On the other hand, Palantir Technologies gained 1.18% to $130.66. Unlike other tech stocks, Palantir is seen as helping AI adoption with its government contracts and enterprise analytics. Investors are separating AI 'winners' from 'losers', which is affecting daily trading.
Inflation
US Consumer Price Index rose 2.4% year over year in January, slightly below expectations of 2.5%. Core inflation came in at 2.5%. However, investors remain cautious. Even with lower inflation, market uncertainty from AI and uneven earnings is keeping volatility high.
