Nvidia Earnings Loom as US Stocks Await Inflation Data and AI Trade Update

US stock futures were largely unchanged in premarket trading on Wednesday as investors digested data from the Personal Consumption Expenditures (PCE) index, which showed inflation remained sticky ahead of the Federal Reserve's Jackson Hole gathering.

The core PCE Index rose 3.3% in July, matching expectations and staying steady from the previous month. This reading came as markets await Nvidia's earnings report, a key benchmark for the health of the artificial intelligence trade.

Futures for the Dow Jones Industrial Average hovered near flat, while S&P 500 futures dipped 0.1%. Contracts tied to the tech-heavy Nasdaq-100 fell 4% after Tuesday's broad gains, according to Yahoo Finance.
