Global financial markets suffered a severe rout on Friday, 6 November, as fears of tighter regulation of artificial intelligence (AI) and a potential slowdown in AI-driven capital spending triggered a sweeping selloff across technology stocks — first on Wall Street overnight and then across Asian bourses. The carnage wiped out roughly $3 trillion in market value from S&P 500 companies alone, marking one of the most punishing sessions for tech equities in recent memory.

Wall Street Sets Off the Alarm

The selloff originated in the United States on Thursday evening, where technology shares came under intense pressure after investors grew concerned that a stronger Democratic presence in Congress could lead to heightened scrutiny of the fast-expanding AI sector. The Nasdaq Composite plunged 5.5 per cent, while the S&P 500 fell over 4 per cent and the Dow Jones Industrial Average dropped 3.4 per cent. Wall Street's volatility index surged sharply higher as forced selling amplified the decline.

Asia Bears the Brunt

South Korea's KOSPI index fell more than 8 per cent, triggering an automatic trading halt before recovering slightly after the market reopened. Japan's Nikkei dropped around 6 per cent, while Taiwan's benchmark index also declined by more than 8 per cent — with technology-heavy markets recording some of the region's steepest single-session losses in recent years.

Key Stocks Hit Hard

Major semiconductor and AI-linked companies bore the heaviest losses. Samsung Electronics declined nearly 10 per cent and SK Hynix slid almost 12 per cent. SoftBank Group — one of the world's largest investors in AI businesses — fell 11 per cent amid mounting concerns over future returns from the sector. According to market experts, the broader decline reflected growing doubts over whether the massive investments being poured into AI infrastructure, chips, and data centres would continue at their current pace if regulators adopt a stricter stance toward the industry.

What Experts Say

Analysts pointed to investor positioning and forced selling as factors that amplified the severity of the downturn beyond what fundamentals alone would justify. The concern, critics argue, is not merely regulatory — it is structural: if AI spending plateaus, the entire supply chain of semiconductors, cloud infrastructure, and data-centre hardware faces an earnings reset. This is notably the first major AI-regulation-driven global selloff of this scale since the sector's investment boom began in earnest.

Commodities and What Comes Next

Not all asset classes suffered. On the commodities front, international benchmark Brent crude rose about 2 per cent to $100.31 per barrel, while US West Texas Intermediate (WTI) crude gained more than 1 per cent to $91.91 per barrel. Markets will now watch closely for any formal regulatory proposals from Washington and responses from major AI companies, which could either stabilise sentiment or deepen the rout in the sessions ahead.
