U.S. equity futures were trading higher on Wednesday after a rally in chip stocks helped lift major benchmarks in the prior session. Investors weighed renewed hopes for a breakthrough in indirect U.S.-Iran negotiations alongside continued interest in companies tied to artificial intelligence infrastructure.
By 03:34 ET (07:34 GMT), futures on the Dow were up about 127 points, or 0.3%. S&P 500 futures were higher by 11 points, or 0.1%, and Nasdaq 100 futures had gained roughly 60 points, or 0.2%. The previous session saw the S&P 500 and the Nasdaq Composite reach fresh record closing highs, while the Dow Jones Industrial Average lagged and finished lower.
Chipmakers led the advance, reflecting robust spending on components and systems used to support artificial intelligence workloads. Analysts cited by market notes observed that talk of Iran dominated headlines, but the dramatic run-up in AI-related stocks was happening independently of developments in the Middle East.
Micron surpasses $1 trillion valuation
Micron Technology was a standout, with shares jumping and lifting the company’s market capitalization above $1 trillion for the first time. The momentum carried into premarket trading on Wednesday, with Micron shares rising by more than 4%.
Demand from technology firms expanding AI capabilities has driven unusually strong interest in high-end memory products. Micron indicated that its entire annual allocation of high-bandwidth memory processors has already been sold out, creating a supply squeeze. That tightness has contributed to a rise in memory-chip prices, bolstering the company’s revenue outlook and attracting significant attention from traders and institutional investors, according to regulatory filings cited in market reports.
Diplomatic movements and ceasefire uncertainty
Markets also remained attentive to the trajectory of talks aimed at ending the almost three-month confrontation between the U.S. and Iran. Reporting indicated that indirect negotiations between Washington and Tehran had continued despite exchanges of fire earlier in the week. U.S. officials described a fragile ceasefire as remaining in place, while Iranian officials warned of retaliation if the truce were breached.
Media coverage this week suggested the U.S. and Iran were close to agreeing on a framework that would extend the ceasefire and permit the reopening of the Strait of Hormuz. The strait is a critical passage for global oil shipments and has been largely closed since the conflict began in late February. A partial reopening of shipping lanes was reported in some instances this week, with a few vessels said to have crossed the channel, although overall flows remain well below pre-conflict levels.
Complicating diplomatic efforts, there were reports of a new clash between Israel’s military and Iran-backed Hezbollah militants in southern Lebanon. Tehran insisted that any peace accord should address the fighting in Lebanon as part of a broader settlement.
Oil retreats
Against the backdrop of these diplomatic signals, Brent crude futures fell. The contract was last trading down 2.2% at $97.38 a barrel, below recent peaks that exceeded $100 a barrel but still elevated relative to levels before the onset of the conflict. The Strait of Hormuz remained a focal point for oil markets given its importance for maritime oil transport and the disruptions caused by hostilities.
Samsung union averts large strike
In corporate labour developments, a majority of unionized workers at Samsung Electronics voted to approve a tentative wage agreement, averting an 18-day strike that had been planned by roughly 48,000 workers, most of whom are employed in Samsung’s semiconductor operations. The union reported that about 74% of participating members supported the deal. Seoul-listed Samsung shares closed higher by 2.7% following the vote.
The government-mediated agreement had been reached after intense negotiations over bonuses and profit-sharing arrangements tied to surging demand for AI memory chips. The settlement removed an immediate risk to global chip supplies and eased a potential source of disruption to South Korea’s economy.
Market implications
Short-term market dynamics were shaped by a mix of industry-specific strength in semiconductors and evolving geopolitical signals that affect commodity flows. Chip sector gains were driven by supply constraints and heightened demand for memory products used in AI systems, while energy markets responded to shifting assessments of shipping access through the Strait of Hormuz. Labour developments in the semiconductor supply chain temporarily reduced the likelihood of near-term production interruptions.
Investors continued to monitor both diplomatic negotiations and sector fundamentals, with attention split between the potential for a stabilized Middle East affecting oil shipments and the persistent, technology-led appetite for memory and AI-related hardware.
