U.S. stocks ended sharply higher on Monday as a rally in artificial intelligence-linked companies lifted sentiment across Wall Street. Optimism surrounding the potential end of the record 40-day government shutdown and renewed appetite for technology shares powered the gains. Nvidia and Palantir led the rebound, extending their dominance as central players in the ongoing AI boom.
The S&P 500 climbed 1.54% to close at 6,832.28, while the Nasdaq Composite jumped 2.26% to 23,524.82. The Dow Jones Industrial Average advanced 0.82% to 47,372.22. The market’s rebound followed weeks of volatility that had tested investor confidence in the AI-driven rally. Analysts said the sharp turnaround reflected a return to risk-taking as political progress in Washington lifted fears of a prolonged economic disruption.
Nvidia surged as investors bought back into the stock after recent weakness, while Palantir extended its gains on renewed enthusiasm for its role in enterprise AI analytics. Tesla also climbed, helping push the broader technology sector higher. “This is a rebound after being slightly oversold last week,” said one strategist, noting that the rapid shift back into AI names shows traders remain confident in the sector’s long-term momentum.
Health insurers fell as the Senate moved to finalize an agreement that would reopen the federal government without immediately extending healthcare subsidies. Centene, Humana, and Elevance Health all declined as investors assessed the near-term policy outlook. Elsewhere, Pfizer shares rose after the company secured a $10 billion deal to acquire Metsera, while Eli Lilly hit an intraday record following an analyst upgrade.
Airlines struggled as staffing shortages and disrupted flight schedules weighed on travel stocks. United Airlines and American Airlines both ended lower, even as traders bet the shutdown would soon be resolved. On betting platform Polymarket, the odds of a government reopening this week climbed to 88%, reflecting growing confidence that political gridlock is easing.
AI remains the primary engine of market growth, with investors looking beyond short-term corrections to focus on how machine learning and data analytics are reshaping corporate performance. Strong third-quarter earnings have reinforced that narrative, with more than 80% of S&P 500 companies beating estimates so far. Despite uncertainty over future interest rate decisions, optimism surrounding artificial intelligence continues to drive capital into U.S. equities.
