Wall Street's AI-driven rally hit a milestone this week, then paused. The S&P 500 closed above 7,800 for the first time in its history on Thursday, a record that capped a summer run built on optimism over artificial-intelligence spending and bets that the Federal Reserve is done raising rates. By Friday's close, the index had slipped back to around 7,786, a decline of roughly 0.2%, as a much weaker-than-expected reading on consumer sentiment and renewed skepticism about the financing behind the AI buildout gave traders reason to book profits.
Even with the Friday pullback, the index finished its third consecutive week higher, according to TheStreet's market recap, and the small-cap Russell 2000 notched its own fresh record on Friday even as the large-cap benchmarks retreated. The Nasdaq Composite, which had jumped 0.81% to a record 26,803.03 on Thursday, eased about 0.3% on Friday to roughly 26,729. The Dow Jones Industrial Average, which had added 69.72 points, or 0.13%, to close at 53,839.99 on Thursday, gave back about 0.2% to close near 53,732, ending the week lower even as the other two indexes held on to gains.
A Record, Then a Reversal
Thursday's push past 7,800 came after a cooler-than-expected July producer price index reading — flat on the month against a forecast for a 0.2% rise — reduced expectations that the Fed would need to raise rates again in September, while crude oil prices slid nearly 3% after the International Energy Agency cut its 2026 demand forecast by 1.6 million barrels a day. The S&P 500 touched an intraday high of 7,816.70 before settling at 7,798.99, a gain of about 0.65%. Technology names led the advance, with Meta Platforms, Micron Technology and Netflix among the biggest contributors to the Nasdaq's gain.
The mood shifted on Friday. A preliminary University of Michigan survey showed consumer sentiment tumbling to 51.0 in August, far below the roughly 54.5 economists had expected and down from July's 55.2, ending two months of improvement. July retail sales also came in soft, falling 0.6% from June. Chipmakers led the retreat: Broadcom tumbled about 6% after Bank of America analysts raised questions about a reported $370 billion debt-financing vehicle tied to the company's data-center buildout, feeding a broader debate over whether hyperscalers are taking on too much leverage to fund AI infrastructure.
What's Driving It, What's Next
The tension between the two days captures where markets stand heading into the fall: investors remain broadly convinced that AI spending will keep corporate earnings growing, while growing more anxious about how that spending is financed and about the health of the underlying consumer. Traders have increasingly priced in the prospect that the Fed's next move is a cut rather than a hike, a shift that has underpinned much of the summer's advance even as data on consumer confidence and spending have sent more mixed signals.
The stock market rose to a fresh all-time intraday high on Thursday as oil prices declined and traders digested cooler-than-expected inflation data, with the S&P 500 surpassing 7,800 for the first time ever and notching a closing record of 7,798.99.
Market summary, Aug. 13 trading session
Whether the rally resumes will likely hinge on incoming data — including the University of Michigan's final August sentiment reading due August 28 — and on how investors reconcile enthusiasm for AI-driven earnings growth with mounting scrutiny of how that growth is being financed. For now, the S&P 500 remains within roughly half a percentage point of its all-time high, having weathered its first material pullback since the rally accelerated this summer without breaking its longer uptrend.
