The escalation of tensions between the United States and Iran dominated market movements as President Trump declared the existing ceasefire over and threatened a blockade of the Strait of Hormuz along with potential seizure of Iran's Kharg Island. Brent crude prices quickly surpassed $80 per barrel, driving bond yields higher and reviving concerns over renewed inflationary pressures. Major indices responded sharply, with the Dow, S&P 500, and Nasdaq all posting declines amid the surge in energy costs and the uncertainty surrounding any potential military action in the region.
Chip stocks faced intense selling pressure that erased roughly $2 trillion in market value, pushing valuations for several leading semiconductor companies back to critical support levels not seen in years. Nvidia alone shed approximately $1 trillion in market capitalization, returning its valuation metrics to levels observed before the recent AI-driven rally. Regulatory restrictions on exports of advanced chips to China compounded the pressure, while reports indicated that Chinese domestic AI chip budgets had risen sharply to 46 percent of total spending, allowing local suppliers to capture greater ground at the expense of foreign providers.
Despite the broad sell-off in semiconductors, select technology names showed resilience or outright gains. Alibaba shares climbed 12 percent on optimism around artificial intelligence initiatives and improving margins. Apple secured a chip supply agreement with Broadcom valued at more than $30 billion, providing a notable positive offset within the sector. OpenAI received regulatory clearance for a broad rollout of its GPT-5.6 model, while Microsoft continued efforts to unify its Copilot offerings in direct competition with rival AI platforms.
Space and related technology developments drew attention as Blue Origin completed a $10 billion funding round at a $130 billion valuation. SpaceX shares remained essentially flat near their initial public offering price, even as trading volume in associated exchange-traded funds reached multi-year highs driven by investor interest. Bitcoin and Ethereum prices declined following reports of U.S. strikes on Iranian targets, and silver prices slipped below $60 per ounce in the same session.
Automotive and industrial companies signaled strategic adjustments amid ongoing competitive challenges. Nissan indicated that an announcement regarding a possible partnership with Honda was imminent. Stellantis explored the launch of a low-cost $14,000 golf cart as one measure to counter declining performance. JPMorgan outlined plans to pursue smaller acquisitions as part of its broader growth approach, while Wells Fargo highlighted risks to traditional telecom operators from potential Starlink competition.
Additional market movements included a 20 percent drop in Korean equities from their peaks as concerns over AI investment intensity spread. IBM introduced new AI infrastructure offerings, prompting questions about whether its valuation fully reflected upcoming contributions. Software developer job postings increased following the release of Claude Code, and Cloudflare launched a partner program aimed at accelerating adoption of AI security tools.
Other equity-specific developments featured sharp gains in Atlassian and Intuit shares on company-specific progress, while Netflix, Disney, and YouTube positioned themselves for a combined $2 billion bid on FIFA broadcasting rights for upcoming World Cups. Eli Lilly and Novo Nordisk continued to demonstrate strength in GLP-1 weight-loss treatments, with attention also turning to alternative names offering exposure to the same therapeutic category.
Broader trading patterns showed futures for the S&P 500, Nasdaq, and Dow holding relatively flat as participants monitored both geopolitical developments and upcoming Federal Reserve policy signals. Intel shares continued to trade at levels last observed during the dot-com era, underscoring prolonged weakness in certain legacy chipmakers. Overall, the session reflected concentrated reactions to energy-price shocks and technology-sector revaluations rather than uniform directional movement across asset classes.
