U.S. stock index futures were in retreat Wednesday night as fresh military operations involving Iran and renewed weakness across technology stocks weighed on market sentiment.
By 19:45 ET (23:45 GMT), S&P 500 Futures were down 0.3% at 7,257.75 points, Nasdaq 100 Futures had fallen 0.5% to 28,419.0 points, and Dow Jones Futures were lower by 0.2% at 49,898.0 points. The declines followed steep losses on Wall Street earlier in the session, where heavyweight technology companies led the drop.
Military escalation and market reaction
The U.S. Central Command said it had launched a new wave of military operations against Iran in what it described as "self-defense" after a public warning from President Donald Trump that more strikes would follow. Iranian state media reported that Tehran threatened a "decisive military response," announced the closure of the Strait of Hormuz, and indicated preparations for additional retaliatory attacks.
The flare-up follows the earlier downing of a U.S. helicopter in the Strait of Hormuz and a period of intermittent strikes between the two countries. The re-escalation appeared to put the fragile ceasefire between the U.S. and Iran at serious risk, injecting fresh geopolitical uncertainty into markets.
Investors also reacted to consumer inflation data for May, which showed a sharp, although in-line, increase. Market participants worried that rising oil prices tied to the conflict could fuel broader inflation and complicate the Federal Reserve's interest-rate outlook, adding pressure on rate-sensitive sectors such as technology.
Oracle after-hours rout
Oracle Corporation was a notable laggard after the bell. Shares plunged nearly 10% in immediate aftermarket trade, and subsequent trading showed a decline of just over 10% as the market absorbed the company’s long-range spending plans.
Oracle said it expects capital expenditures of up to $95 billion in fiscal 2027 - a figure significantly above Wall Street’s rough expectation of about $68 billion. The company also acknowledged that it had exceeded its fiscal 2026 capex target and plans to raise $40 billion in debt and equity financing in 2027.
Those projections largely overshadowed Oracle’s quarterly results, which were stronger than analysts had anticipated. Market participants interpreted the outsized spending and financing plans as evidence that the company is taking on additional leverage to fund an expanded push into artificial intelligence infrastructure, including positioning itself as a major data-center provider for large customers such as OpenAI.
The aggressive capex outlook fed into broader doubts over the sustainability of the AI-led trade, contributing to a rotation out of technology that has intensified in recent sessions. Heavyweight chipmakers and other tech names incurred notable losses as investors recalibrated expectations for AI investment and assessed the impact of potentially higher interest rates on long-duration tech earnings.
Market breadth and recent moves
On Wednesday, the S&P 500 fell 1.6%, the NASDAQ Composite slid nearly 2%, and the Dow Jones Industrial Average declined 1.9%. The tech sector bore much of the damage amid concerns over AI spending dynamics and macroeconomic pressures.
Attention in markets this week is also focused on a major corporate event: the planned $1.75 trillion listing of SpaceX on Friday, which investors say comes amid broader unease about valuation levels in parts of the technology sector.
What this means for investors
Elevated geopolitical risk from the U.S.-Iran hostilities, uncertainty about the trajectory and funding of large-scale AI investments, and the inflationary implications of rising oil prices combined to pressure equities, particularly growth-oriented technology stocks. Futures activity late Wednesday reflected those same concerns as traders reassessed exposure ahead of potential further escalation or policy responses that could influence interest rates.
Given the mix of geopolitical and corporate developments, market participants are weighing the implications for sectors tied to energy prices, defense-related uncertainty, and capital-intensive cloud and data-center investments.
