US stock markets opened in negative territory Monday as concerns about artificial intelligence development weighed on investor sentiment.

US equity markets kicked off the week on a downbeat note Monday, with technology stocks leading losses as major artificial intelligence executives signaled a shift toward more cautious development strategies.

Opening Bell Sees Broad Declines

In early trading, the tech-focused Nasdaq Composite tumbled 1.23%, shedding 319.57 points to reach 26,013.47 and hitting multi-week lows during the session. The benchmark S&P 500 dropped 0.73%, while the blue-chip Dow Jones Industrial Average declined 0.29%.

AI Industry Leaders Advocate for Moderation

The market weakness followed weekend comments from Anthropic CEO Dario Amodei, who proposed a three-phase framework for AI companies to moderate their model capabilities and allocate more time for risk management. His call for restraint found support from prominent figures including Elon Musk of xAI and Sam Altman of OpenAI, signaling a potential industry-wide recalibration.

Adding to the cautious sentiment, OpenAI announced it has shelved plans for an initial public offering this year, marking a significant strategic shift for one of the sector's highest-profile companies.

Semiconductor Sector Faces Sharp Selloff

The semiconductor index plunged 5.9%, on track for its worst single-day performance since July 1st if losses hold. Major chipmakers absorbed heavy losses, with Intel sliding 5.94%, AMD dropping 5.76%, and Marvell Technology declining 6.70%.

Technology giants also retreated, with declines ranging from 1.29% to 3.48% for companies including Nvidia, Amazon, and Meta Platforms.

Software Stocks Find Relief

In contrast to the semiconductor rout, enterprise software companies—which had suffered last week on concerns about AI disruption to their business models—staged a recovery. Servicenow advanced 4.32%, Adobe gained 3.19%, and Workday climbed 3.64%.

Inflation and Oil Concerns Compound Pressure

Beyond AI-related worries, investor confidence was already fragile following last week's Consumer Price Index data showing accelerating US inflation. The hotter-than-expected numbers have raised expectations that the Federal Reserve may implement a rate increase Wednesday when its two-day monetary policy meeting concludes.

Meanwhile, crude oil continued its climb, with Brent trading near $110 per barrel—levels not seen since May—adding another layer of concern for markets already grappling with multiple headwinds.
