Wall Street Ends Winning Week With Records as AI Momentum, Energy Stocks Lift S&P 500 and Dow Despite Shutdown Uncertainty
Published: October 4, 2025, 16:00 EDT
U.S. stocks closed out the week on a strong note Friday, extending record highs despite concerns over government shutdown delays and signs of uneven economic growth. The S&P 500 secured its seventh gain in the past nine weeks, while the Dow Jones Industrial Average added to its rally.
Fueled by optimism in artificial intelligence investments and steady performances from key sectors, Wall Street largely shrugged off political uncertainty and mixed economic data.
S&P 500 and Dow Continue Record Streak
The S&P 500 rose less than 0.1%, finishing at 6,715.79 points, capping another week of gains. The Dow Jones Industrial Average climbed 238.56 points, or 0.5%, to 46,758.28, while the Nasdaq composite slipped 0.3% to 22,780.51 after giving up early gains.
Both the S&P 500 and Dow set new all-time highs on Thursday, highlighting investor confidence despite broader economic concerns. The Nasdaq, heavily weighted with technology companies, faced pressure after several key stocks reversed intraday advances.
Government Shutdown Delays Key Economic Data
Typically, the first Friday of the month brings the closely watched U.S. jobs report, which provides critical insights into employment trends and unemployment rates. However, the ongoing U.S. government shutdown, now in its third day, delayed the release of the report along with other key economic updates, including weekly jobless claims.
Economists note that past shutdowns have not significantly harmed financial markets or the economy, but the current political standoff has added a layer of uncertainty. President Donald Trump has suggested the possibility of mass federal worker layoffs, though analysts caution that such threats may not materialize.
For Wall Street, the most important factor remains whether the labor market is cooling enough to encourage the Federal Reserve to maintain interest rate cuts, a trend that has supported market gains this year.
