S&P 500 Hits Record High as Oil Prices Plunge

The S&P 500 and Dow Jones Industrial Average reached new record highs on August 4, 2026, fueled by a combination of strong corporate earnings and easing geopolitical tensions. The S&P 500 hit an intraday peak of 7,700 and a record high near 7,687, marking its first new closing record since June.

Scott Bessent, the U.S. Treasury Secretary, drove market optimism by announcing that the United States and Iran are in talks to reopen the Strait of Hormuz. This news caused WTI crude prices to drop 4.2% to $76.90 a barrel, easing inflation concerns and boosting investor sentiment.

Corporate results in the artificial intelligence sector further propelled the rally. Palantir Technologies Inc. shares surged over 25% after reporting quarterly revenue of $1.935 billion and adjusted earnings per share of $0.41. Caterpillar Inc. also saw gains of up to 10% after raising its annual revenue growth forecast due to AI data center demand. In additional infrastructure developments, Anthropic signed a $10 billion, six-year computing capacity deal with Volta Infra Holdings, utilizing a site in Norway.

Despite the gains, financial analysts warned that the recovery may be tempered by historical seasonal weakness typically observed between August and October.
