Nvidia ( NVDA 4.08%) became the first company to reach $4 trillion in market cap on Wednesday -- an incredible feat considering the company was worth a fraction of tech giants Apple and Microsoft just a few years ago.

US Stock market today climbed as Nvidia stock surged on hopes of renewed AI chip sales to China, with support from President Trumps trade policy shift. The S&P 500 gained 0.4% and the Nasdaq rose 0.8%,

The market capitalization of the S&P 500 ( SPX) rose almost 6.3% during the second quarter of 2025. Standard & Poor's reports the index ended 2025-Q2 with a market cap of $52.50 trillion, a net gain of $3.09 trillion from the $49.41 trillion recorded at the end of 2025-Q1.

It's a tale of two markets. The S&P 500--a benchmark for the stock market--is wavering between small gains and losses, while the tech-heavy Nasdaq, higher by 0.7%, has plans to etch a new all-time high today.

U.S. stock futures were mostly higher Tuesday after Nvidia set it's likely to resume sales of key chips to China, with a key inflation report and bank earnings on the way. Dow Jones Industrial Average futures fell 71 points,

The S&P 500 ended Tuesday marginally lower after President Donald Trump said that there would be no extensions on his new Aug. 1 tariff deadline.
