Wall Street powered to fresh record highs on Tuesday, August 4, 2026, as blowout results from Palantir Technologies and Caterpillar reignited enthusiasm for artificial intelligence and industrial spending, while a possible breakthrough on the Strait of Hormuz sent oil prices sharply lower. The Dow Jones Industrial Average jumped 907.47 points, or 1.71%, to close above 54,000 for the first time, the S&P 500 surged 1.79% to a record 7,736.52, and the Nasdaq Composite gained 2.59% to 26,584.99. The gains extended a rally that began the previous session and pushed all three benchmarks to fresh closing highs in the same week.
Palantir's Blowout Quarter
Palantir shares surged more than 27% after Chief Executive Alex Karp described an "otherworldly" quarter, with revenue up 93% year over year to 1.94 billion dollars and US commercial revenue up 149%. The company raised its full-year revenue guidance to roughly 8.15 billion dollars, its largest upward revision to date. The result reinforced the view that enterprise demand for AI software remains strong even as investors debate the sustainability of the stock's valuation, which has become one of the more contentious questions among strategists covering the AI trade, given how far the shares have climbed relative to traditional software peers.
Caterpillar Adds to the Rally
Caterpillar shares climbed 5.6% after the heavy-equipment maker posted its first quarter with more than 20 billion dollars in sales and revenue, beating analyst expectations on both the top and bottom lines. Executives pointed to strong order rates and a growing backlog across the company's core businesses, a signal that industrial and infrastructure spending remains resilient. The report added an industrial complement to a rally otherwise led by technology names, broadening the base of the day's advance beyond the usual AI-linked leaders and offering some reassurance that the economic expansion still has support outside the technology sector.
Oil Slides on Hormuz Hopes
Crude prices fell sharply, with Brent dropping below 80 dollars a barrel after Treasury Secretary Scott Bessent said a deal affecting the Strait of Hormuz could be reached within days. The prospect of eased tensions in the region removed a source of risk premium that had supported prices in recent weeks, and energy shares lagged the broader market as a result. Lower energy costs also fed into the day's generally upbeat risk appetite across sectors, giving consumer and industrial names an additional tailwind alongside the earnings-driven gains.
Eyes Turn to Friday's Jobs Report
A JOLTS report showed 7.4 million job openings in June, in line with expectations, offering a steady if unremarkable data point ahead of Friday's more closely watched July employment report. With the market at record levels and earnings season largely behind it, the jobs number stands as the next major test of whether the economy is cooling in a way that could shape the Federal Reserve's next moves. Traders should brace for volatility around the release, given how much of the market's recent advance now rests on the assumption of a still-resilient labor market.
