Here are five key things investors need to know to start the trading day:
1. Stocks rebound

Tariff news continues to make headlines as market participants count down to Thursday — the most recent deadline set by the White House for it to start collecting tariffs from some trading partners. President Donald Trump said Monday that he would “substantially” hike tariffs on goods coming from India because the country buys Russian oil. The European Union also announced Monday that it would delay enacting planned tariffs on the U.S. for six months. Trump will join CNBC’s “Squawk Box” for an interview at 8 a.m. ET Tuesday morning.

Palantir, the buzzy and mysterious defense technology stock, recorded quarterly revenue of $1 billion for the first time. It’s an important milestone for the company, which has seen its shares skyrocket and become a favorite of retailer investors given its futuristic focus and eccentric CEO, Alex Karp. As CNBC’s Samantha Subin notes, the Denver-based company has become a beneficiary of Trump’s governmental cost-cutting initiatives, with its U.S. government revenues jumping 53% year-over-year. Palantir shares popped in extended trading following its earnings report.
4. ChatGPT’s next milestone

This week, OpenAI’s ChatGPT products are poised to reach 700 million weekly active users. There’s a few ways to show just how much that number has ballooned with artificial intelligence’s move into the mainstream. First, it’s up about 40% from March alone. Even more eye-popping, the number has grown more than fourfold from a year ago. ChatGPT’s number of paid business users is also accelerating, up to five million from three million in June.
5. American Eagle’s wingman

After getting caught in controversy over its new advertising campaign starring actress Sydney Sweeney, American Eagle got a vote of confidence from the White House on Monday. Trump called the campaign the “‘HOTTEST’ ad out there” in a social media post. He also said that Sweeney, who’s known for roles in “Euphoria” and “The White Lotus,” is a registered Republican. American Eagle’s shares surged more than 23% following the president’s post, marking the Pittsburgh-based company’s best day in about a quarter of a century.
