Wall Street's recent record-setting rally was brought to a halt on Tuesday, influenced by weakening artificial intelligence (AI) stocks and a notable climb in oil prices amidst continued concerns over the Iran war. The S&P 500 experienced a 0.4% dip from its latest all-time high, while the Nasdaq composite fell 0.7% from its own record. In contrast, the Dow Jones Industrial Average, which has a lesser emphasis on technology stocks, showed resilience, rising by 32 points, or 0.1%, as of late morning Eastern time.

Stocks within the artificial intelligence sector were prominent in leading the market lower. Nvidia, a key supplier of chips powering much of the AI revolution, saw its shares sink by 1.7%, making it the heaviest drag on the S&P 500. Other significant players, Oracle and Broadcom, also experienced declines, falling 2.6% and 3.2% respectively. This weakness followed a report in The Wall Street Journal indicating concerns among some leaders at OpenAI regarding its ability to sustain massive spending on data centers, particularly after missing targets for new users and revenue. This situation reignited criticism that the entire AI industry might be in an over-the-top spending bubble, potentially failing to generate the necessary profits and productivity to justify such investments. The drops occurred just a day before several of the biggest AI spenders—Alphabet, Amazon, Meta Platforms, and Microsoft—are scheduled to release their latest quarterly results for the beginning of 2026, which are expected to offer further insights into the returns on AI investments.

Adding to the market's pressures was another increase in oil prices, fueled by ongoing uncertainty surrounding the Iran war. The price for a barrel of Brent crude oil slated for June delivery climbed 2.3% to $110.72. Brent for July delivery, a key focus for oil traders, also rose 2.3% to $104.00. These prices are nearing the $119 peak reached when war-related anxieties were at their highest, having rebounded significantly from approximately $70 in late February. The Strait of Hormuz remains a critical point of focus, as its potential closure could impact global oil shipments from the Persian Gulf. The Trump administration appeared unlikely to accept Iran's proposal to reopen the Strait of Hormuz in exchange for the U.S. lifting its blockade, a proposition that would delay discussions on Iran’s nuclear program, which U.S. Secretary of State Marco Rubio seemed to dismiss. Concurrently, the average price for a gallon of gasoline in the United States reached $4.18 on Tuesday, marking the highest level since 2022, according to AAA.

Despite the broader market declines, some sectors and companies posted gains. Coca-Cola notably helped to mitigate the market’s losses, with its stock rallying 5.5% after reporting stronger-than-expected profit and revenue for its latest quarter, driven by robust performance in China, the United States, and India. Oil companies also performed strongly, benefiting from the surge in crude prices, with Exxon Mobil gaining 1.2% and Chevron rising 1.7%. In London, BP's stock added 0.5% following the British petroleum giant's announcement that its first-quarter profit more than doubled.

In the bond market, Treasury yields edged higher after a report indicated a slight improvement in U.S. consumer confidence in April, contrary to economists' expectations of a decline. The yield on the 10-year Treasury ticked up to 4.36% from 4.35% recorded late Monday. The Federal Reserve is scheduled to convene on Wednesday to announce its latest decision on short-term interest rates. Widespread expectations are that the Fed will maintain the federal funds rate, delaying further cuts. While lower interest rates could bolster the economy, they also carry the risk of exacerbating inflation, especially with rising oil prices and the threat of new tariffs pushing prices higher. Also on Wednesday, the Senate Banking Committee is slated to vote on confirming Kevin Warsh as Trump’s nominee to succeed Fed Chair Jerome Powell, with committee approval anticipated to send his nomination to the full Senate.

Internationally, stock markets predominantly experienced declines across Europe and Asia. Japan's Nikkei 225 saw one of the world's larger losses, sinking 1% after the Bank of Japan, in a split vote, chose to keep its key interest rate unchanged. The Bank of Japan's statement highlighted
