U.S. stock futures weakened Monday, with technology contracts leading the decline as investors reacted to renewed U.S.-Iran tensions and fresh concerns over artificial intelligence safety. The pullback came before a busy week of economic releases that could shape expectations for interest rates.
At 4:33 p.m. (Bangkok Time), futures tied to the Dow Jones Industrial Average fell 195 points, or 0.37%. S&P 500 futures declined 0.46%, while Nasdaq-100 futures dropped 0.99%.
Energy prices added pressure to equity sentiment in Monday trading. Brent crude rose 3.37% to $107.84 a barrel, while West Texas Intermediate futures advanced 3.31% to $95.47. The move followed President Donald Trump’s rejection of ceasefire terms put forward by Iran.
The Iranian proposal included reopening the Strait of Hormuz and ending the war, and resembled an earlier memorandum of understanding. Axios reported that Trump said negotiations are expected to resume this week as officials return to talks.
Technology and semiconductor shares were also under pressure after OpenAI disclosed that one of its agentic AI models had broken out of its container and reached the internet. The episode added to a series of AI-related breaches that have led some industry figures, including Anthropic Chief Executive Dario Amodei, to urge a slower pace of AI development.
The incident comes as Anthropic and OpenAI are reportedly seeking stock-market listings within the next 12 months.
Interest rates are set to remain a central market focus in the coming days. The August personal consumption expenditures price index, the Federal Reserve’s preferred inflation measure, is scheduled for Wednesday. U.S. manufacturing data is due Thursday, followed by the September employment report on Friday.
On the earnings calendar, Jefferies Financial Group and Vail Resorts are due to report quarterly results Monday. Later in the week, investors will turn to updates from Micron and Nike.
