Stocks Today: AI Fears, Iran Attacks & Market Volatility – What to Watch This Week

Stocks Today: AI Fears, Iran Attacks & Market Volatility – What to Watch This Week

February 28, 2026 Laura Fontaine - Entertainment Editor Entertainment

The entertainment industry, already navigating a period of significant disruption fueled by artificial intelligence, finds itself bracing for further turbulence as geopolitical tensions escalate. While Wall Street absorbed anxieties about AI’s economic impact and persistent inflation last week, a far more serious crisis unfolded with the commencement of what President Donald Trump described as “major combat operations” in Iran Saturday. This development casts a long shadow over global markets and adds another layer of uncertainty to an already volatile landscape.

The situation unfolded rapidly. Following a Truth Social post on Friday, Trump ordered all U.S. Government agencies to “immediately cease” using technology from Anthropic, the AI firm behind the chatbot Claude. This action, as reported by CNBC and India Today, stemmed from a dispute over the Pentagon’s demands for unrestricted access to Anthropic’s AI models. Anthropic had sought assurances that its technology would not be used for fully autonomous weapons or mass domestic surveillance, requests the Pentagon strongly resisted. Defense Secretary Pete Hegseth subsequently designated Anthropic a “Supply-Chain Risk to National Security,” effectively blacklisting the company from future government contracts.

The timing of this move, coinciding with escalating tensions in the Middle East, is striking. While the direct connection between the Anthropic ban and the military actions in Iran remains unclear, it underscores a broader trend of heightened scrutiny surrounding the deployment of AI, particularly in sensitive national security contexts. The Pentagon’s insistence on unfettered access to Anthropic’s technology suggests a desire to leverage AI capabilities in the ongoing conflict, raising ethical and strategic concerns.

Anthropic responded to the ban with “deep sadness,” vowing to challenge the supply chain risk designation in court. The company argued that the move was “legally unsound” and would set a “dangerous precedent” for American companies negotiating with the government. This stance highlights a growing tension between the tech industry’s desire to innovate and the government’s need to maintain control over potentially disruptive technologies.

The financial markets reacted to the confluence of these events with unease. Oil prices soared on Friday amid concerns about potential supply disruptions in the Middle East. Stocks also experienced a rough session, weighed down by both geopolitical anxieties and lingering fears about the economic impact of AI-driven job losses. Fintech firm Block’s recent layoff of nearly half its workforce further fueled these concerns.

February proved to be a challenging month for the S&P 500 and Nasdaq, with both indexes posting their worst monthly losses since March 2025, declining nearly 1% and 3.4% respectively. The market saw a rotation away from chip stocks, with Nvidia falling nearly 6.7% despite positive quarterly results. Broadcom followed suit, losing almost 4%. Conversely, industrial AI plays like Corning saw gains, jumping 7.8%, benefiting from increased demand for data centers and fiber optic cables. Qnity Electronics, a materials supplier for high-performance AI chips, emerged as a standout performer, with shares jumping 11.7% following a strong earnings report.

Software stocks experienced a mixed performance. Salesforce bounced back after a period of underperformance, advancing 5.2%, aided by better-than-expected earnings and positive commentary on its AI-powered Agentforce platform. However, cybersecurity names like CrowdStrike and Palo Alto Networks faced headwinds after Anthropic announced a new cybersecurity tool, sparking concerns about increased competition. CrowdStrike lost 4.3% for the week, while Palo Alto Networks managed a slight gain of 0.15%.

Financial names also came under pressure following a research report warning of potential massive white-collar layoffs due to rapid AI adoption. Capital One, Wells Fargo, and Goldman Sachs all declined on Monday, the first trading day after the report’s publication. Despite the negative sentiment, investors used the weakness in Wells Fargo and Capital One as buying opportunities, anticipating an overreaction to the report.

The situation with Anthropic and the broader anxieties surrounding AI’s impact on the economy and national security underscore a critical moment for the tech industry. The government’s willingness to blacklist a leading AI firm over concerns about its technology’s potential misuse signals a more assertive approach to regulating AI development and deployment. As the conflict in Iran unfolds, the entertainment industry, like the rest of the world, will be closely watching how these events shape the future of technology and global stability.
