Technology stocks experienced a significant downturn globally as leading figures in Artificial Intelligence called for a deliberate slowdown in AI development, citing potential threats to humanity. This sentiment clashed with the views of former President Donald Trump, who champions AI as a crucial economic driver.

The Nasdaq Composite saw a decline of over 1 percent in early trading, and the Philadelphia Semiconductor Index, which tracks chipmakers, fell as much as 6 percent. Major players like Arm Holdings, Nvidia, Advanced Micro Devices, and Micron Technology all registered losses.

The sell-off followed statements from heads of major AI companies, including Dario Amodei of Anthropic, Sam Altman of OpenAI, and Elon Musk, who leads SpaceX and Tesla. They urged a more cautious approach to AI advancement, expressing concerns about the technology's potential harms.

Amodei specifically warned that AI agents could potentially compromise the internet within six months to a year if robust safety protocols are not prioritized. Altman and Musk echoed these concerns, with Altman also indicating a pause in plans for an OpenAI stock market listing due to these safety considerations.

These concerns had a ripple effect in Asian markets overnight, with South Korea's Kospi index dropping 3.3 percent, and chipmakers SK Hynix and Samsung Electronics falling by 6.4 percent and 4.1 percent, respectively. In Tokyo, the tech investment firm SoftBank plunged 10.7 percent, contributing to a 0.8 percent dip in the Nikkei index.

Concerns over rising interest rates and an increase in oil prices above $109 a barrel also contributed to the negative market sentiment. Analysts noted that the combination of oil price surges and AI-related anxieties created a dual challenge for investors, compounded by a rebound in bond yields and a loss of momentum in equity markets.

In contrast, the UK's FTSE 100 index showed resilience, rising 0.4 percent. Gains in oil majors BP and Shell, alongside a shift by investors from AI-focused stocks to more traditional UK market assets, supported the index. Software and data companies, previously under pressure from AI revolution fears, saw a recovery, with Sage, RELX, and London Stock Exchange Group all posting gains.

The debate over AI's pace of development has placed industry leaders at odds with former President Trump. He has emphasized the technology's importance for economic growth and the United States' global leadership, particularly in relation to China. Trump characterized concerns about AI as a "sick conspiracy" that benefits other nations, stating, "Whoever wins AI, wins. We are leading China, and all others, and will continue to do so."

Market analysts suggest that a slowdown in AI spending could have broader economic implications, potentially impacting key market sectors that have experienced growth fueled by AI investment.
