U.S. equities moved higher Wednesday as a softer-than-feared inflation reading reinforced expectations that the Federal Reserve can keep interest rates unchanged in September. The S&P 500 gained 0.26% to close at 7,748.50, while the Nasdaq Composite advanced 0.54% to 26,588.49. Technology stocks provided additional support as strong results from CoreWeave and Super Micro Computer renewed confidence in artificial intelligence infrastructure demand.

Inflation Keeps the Fed on Hold

July’s consumer price index broadly matched expectations, giving investors little reason to revive immediate concerns about another rate increase. Headline CPI increased 0.1% month over month, while annual inflation reached 3.4%. Core CPI, excluding food and energy, rose 0.2% during the month and 2.5% from a year earlier. Both annual measures eased slightly from June.

The data followed last week’s unexpectedly weak jobs report, strengthening the market narrative that the Federal Reserve may have less reason to tighten policy further. Fed funds futures were pricing in roughly a 60% probability of rates remaining at 3.50% to 3.75% at the September meeting, compared with just over 45% a week earlier.

Still, the inflation outlook remains vulnerable to energy prices. Oil traded above $83 per barrel as uncertainty surrounding the Strait of Hormuz continued to threaten global supply routes. A renewed energy-price shock could complicate the Fed’s policy calculations if it begins feeding into broader consumer prices.

AI Stocks Lead the Technology Rebound

Technology shares benefited from the combination of stable inflation expectations and reassuring corporate results. CoreWeave jumped 19% after reporting stronger-than-expected second-quarter adjusted operating income margins of 5%, while revenue doubled from the prior year. The results helped reinforce the view that demand for AI cloud infrastructure remains resilient despite the enormous capital requirements across the industry.

Super Micro Computer also gained 19% following strong earnings and a favorable revenue outlook. The reaction extended beyond the two companies, with Dell Technologies rising nearly 10%, Micron Technology gaining almost 5%, and Cisco Systems advancing close to 3%. U.S.-listed shares of Nebius surged 34%, further highlighting the market’s appetite for companies positioned around AI computing infrastructure.

The breadth of the move is significant because investors have increasingly questioned whether AI spending can maintain its pace as hyperscalers commit enormous amounts of capital. Stronger results from infrastructure providers offer evidence that spending is still translating into substantial demand.

Wall Street Balances Growth Against Energy Risks

The Dow Jones Industrial Average slipped 21.58 points, or 0.04%, to 53,770.27, showing that the session was not a broad-based risk rally. Instead, investors concentrated on technology and growth stocks that stand to benefit from stable financing conditions and sustained AI investment.

At the same time, oil remains an important risk factor. Prices above $83 per barrel could keep inflation pressures elevated, particularly if disruptions around the Strait of Hormuz persist. This creates a difficult policy backdrop: weakening employment argues for avoiding further tightening, while higher energy costs could prevent inflation from falling quickly enough.

Market Outlook

The next phase of the market will depend on whether inflation remains contained while economic growth and corporate earnings hold up. For now, the combination of a tame CPI report and resilient AI earnings supports the case for a September rate pause and continued strength in technology stocks. However, another surge in energy prices or unexpectedly firm inflation data could quickly change rate expectations.

Investors will therefore be watching the next inflation readings alongside corporate guidance for signs that AI infrastructure spending remains sustainable. If those indicators remain favorable, the S&P 500 could continue testing record territory. If energy disruptions intensify or inflation reaccelerates, the market may face renewed pressure as expectations for monetary policy adjust.
