Dow Jones and S&P 500 hit record highs as oil falls and AI earnings fuel rally

The S&P 500 and Dow Jones Industrial Average hit record highs on August 4, 2026, driven by falling oil prices on hopes of a U.S.–Iran agreement and strong corporate earnings tied to artificial intelligence, with Palantir and Caterpillar among the session's biggest gainers.
The S&P 500 and the Dow Jones Industrial Average climbed to new record highs on August 4, 2026, capping a powerful rally on Wall Street. The S&P 500 rose 1.8% during the session, surpassing its previous all-time high set a few months earlier, while the Dow gained roughly 900 points, according to reports. The Nasdaq Composite also moved higher. Two forces drove the gains. Oil prices fell on optimism about a potential agreement between the United States and Iran, easing pressure on markets. At the same time, strong corporate earnings — including results tied to artificial intelligence — lifted sentiment. Shares of Palantir Technologies and Caterpillar rose sharply during the session. The records matter because they follow a turbulent stretch for investors. Late July brought whipsaw sessions, a Federal Reserve rate decision and the highest 10-year Treasury yield since January. The rally suggests markets have, for now, set those worries aside.
S&P 500 and Dow hit record highs as oil slides and earnings impress
Wall Street's two most closely watched benchmarks climbed to fresh record highs on August 4, 2026, capping a powerful session driven by easing geopolitical tension and a heavy slate of corporate results.
The S&P 500 rose 1.8% during the session, surpassing the all-time high it had set a few months earlier. Some reports put the gain at 1.7% while the index traded at record levels; the precise closing figure had not been confirmed. The Dow Jones Industrial Average, the 30-company index of prominent U.S.-listed firms, gained roughly 900 points, according to reports.
According to reports, the session marked the first intraday record highs for both the S&P 500 and the Dow since early June, ending a stretch in which the indexes had failed to push past their previous peaks. The Nasdaq Composite also advanced, reportedly gaining 2.3% as technology stocks rallied across the board.
The rally extended momentum built a day earlier. On August 3, the Dow had risen more than 700 points to close at a record, as signs of easing Middle East tensions pushed crude oil prices lower, according to reports. Investors had entered the week braced for a crowded calendar of earnings reports, and early results appeared to justify the optimism.
Among the standout movers, Palantir Technologies shares climbed about 30%, according to reports, while Caterpillar also rose sharply. Reports said both companies issued upbeat forecasts tied to demand for artificial intelligence. SpaceX, AMD and Arista were among the notable earnings-related movers in late trading, according to reports.
Reports also suggested the S&P 500 and Nasdaq Composite were on track for their strongest four-day stretch in some time, underlining how quickly sentiment had shifted after a volatile end to July.
Hopes of a U.S.–Iran deal pull oil prices down and lift stocks
Crude oil prices fell sharply in the days surrounding the record session, and market reports linked the decline to growing optimism that the United States and Iran could reach some form of agreement. Traders appeared to price in the possibility of reduced geopolitical risk in the Middle East, a region central to global oil supply. According to reports, that optimism helped drag crude lower on both August 3 and August 4, easing one of the pressures that had weighed on markets in late July.
Caution is warranted on the details. The connection between the oil decline and hopes of a deal is reported, not confirmed. The terms of any potential agreement remain unknown, and there is no confirmation that an agreement has actually been reached. Investors were, in effect, trading on the prospect of de-escalation rather than on any signed accord.
Cheaper crude tends to support equities for straightforward reasons. Lower oil prices reduce fuel and transport costs for companies, which can lift profit margins across industries from airlines to manufacturing. Falling energy costs also ease inflationary pressure, giving central banks more room to hold or cut interest rates — a combination equity markets typically reward. That dynamic appeared to underpin the broad-based buying that carried the major indexes to records.
Palantir and Caterpillar lead an AI-driven earnings rally
Corporate earnings did much of the heavy lifting in the rally, and results tied to artificial intelligence were at the centre of it. Strong reports from companies with AI exposure helped drive the broader market gains, giving investors fresh evidence that heavy spending on the technology is translating into revenue.
Palantir Technologies was the standout of the session. Its shares climbed about 30%, according to reports, one of the biggest single-day moves among large U.S. companies. Caterpillar, the industrial equipment maker, also rose sharply. Both companies reportedly issued upbeat forecasts driven by demand linked to artificial intelligence — a pairing that underlined how far the AI trade has spread beyond pure technology firms into corners of the market such as heavy machinery.
The earnings momentum extended into late trading. SpaceX, AMD and Arista were among the notable earnings-related movers after the regular session, according to reports, suggesting that investors were still digesting results well beyond the closing bell.
The pattern matters because of what preceded it. Only days earlier, chip stocks had sold off as investors rotated away from AI-linked shares toward sectors that had lagged earlier in the year, according to reports. The strong forecasts from Palantir and Caterpillar appeared to reverse at least some of that scepticism, pulling buyers back into the AI trade.
Investors had entered the week braced for a heavy slate of corporate earnings reports, and the results tied to artificial intelligence gave them the clearest reason yet to push the major indexes to fresh highs.
A volatile fortnight: Fed decision, yield spike and whipsaw sessions before the rally
The record session on August 4 capped two weeks of sharp swings on Wall Street. According to reports, the turbulence began in the final days of July, when investors were juggling escalating Middle East tensions, a Federal Reserve rate decision and a heavy calendar of earnings from companies including Microsoft and Meta.
On July 28, the Dow Jones Industrial Average rose more than 600 points, reports suggest, even as chip stocks sold off and investors rotated away from artificial-intelligence-linked shares toward sectors that had lagged earlier in the year. The move reversed abruptly the following day. On July 29 the Federal Reserve left interest rates unchanged, and the Dow fell about 800 points, according to the reports.
Bond markets added to the unease. In late July, the 10-year U.S. Treasury yield reached its highest level since January, a sign of pressure building beneath the equity market. The month then ended on a sour note: on July 31, major U.S. indexes fell to close out a volatile week, with Apple and other technology shares declining, even as Amazon shares rose sharply, according to the reports. For July as a whole, the Dow managed a small gain while the Nasdaq Composite and S&P 500 declined.
Sentiment shifted at the start of August. On August 3, the Dow rose more than 700 points to close at a record, reports suggest, as signs of easing Middle East tensions pushed crude oil prices lower and lifted the broader market. Investors were simultaneously bracing for a week packed with corporate earnings reports. That combination — cheaper oil, calmer geopolitics and a crowded earnings calendar — set the stage for the rally that followed.

The index and the publisher: two things called Dow Jones
The name "Dow Jones" refers to two different things, and the distinction matters when reading market news. The Dow Jones Industrial Average is a stock market index made up of 30 prominent companies listed on United States stock exchanges. It is one of the oldest and most widely followed measures of American blue-chip performance, and it is the index that reached a record high in the latest session.
Dow Jones & Company, by contrast, is an American publishing firm. It is owned by News Corp and led by chief executive Almar Latour. Its titles include The Wall Street Journal, Barron's, MarketWatch, Mansion Global, Financial News and Private Equity News.
The two share a name and a history, but they are not the same entity. When headlines report that "the Dow" has risen or fallen, they mean the 30-stock index, not the publisher. The company merely produces the journalism and data through which many readers follow it.
What investors watch next
The rally arrives at the start of a crowded earnings calendar. Investors entered the week of August 4 bracing for a heavy slate of corporate results, and reports suggested the S&P 500 and Nasdaq Composite were on track for their strongest four-day stretch in some time. That momentum will be tested as more companies report, with artificial intelligence demand now a central question for investors weighing whether the AI-linked gains of recent sessions can be sustained.
Several things remain unclear. The Dow Jones Industrial Average's exact closing level and its percentage gain on August 4 were not immediately established, with reports indicating only a gain of roughly 900 points. Sources also gave differing figures for the S&P 500's rise, putting it at either 1.7% or 1.8%. And while optimism over a possible agreement between the United States and Iran helped push oil prices lower, the terms of any such deal were not known, and it remained uncertain whether an agreement would actually be reached.
