Global Markets Rout as AI Selloff Deepens Amid US Political Shifts

Global markets reeled on November 6, 2026, as a punishing sell-off in artificial intelligence stocks wiped $3 trillion from S&P 500 firms and triggered steep double-digit declines across Asian and European exchanges. The dramatic reversal, which RTE.ie reported as the steepest decline in US equities since the tariff-triggered Liberation Day sell-off in April 2025, exposed fragile investor sentiment over the return on investment for capital-intensive artificial intelligence infrastructure. Wall Street’s volatility fear gauge surged as the Nasdaq plummeted 5.5% and entered correction territory, closing more than 10% below its recent highs.

The Bottom Line:

The Nasdaq tumbled 5.5% in a single session, sending the index into correction territory and wiping over $3 trillion in market capitalization from S&P 500 companies.
Asian semiconductor heavyweights bore the brunt of the overnight panic, with South Korea’s Kospi dropping over 6% and Japan’s Nikkei 225 plunging roughly 6% to enter bear market territory.
Political shifts following Democratic victories in the US midterm elections intensified investor fears regarding potential regulatory headwinds and stricter scrutiny on data center construction.

Global Semiconductor Rout Deepens Across Asian Exchanges

A sell-off in artificial intelligence stocks spread to Asian markets. Japan’s Nikkei slumped 7% initially before settling at a roughly 6% loss, dragging the benchmark below the 60,000-point level for the first time since May, as noted by the Irish Examiner. South Korean and Taiwan equity indices dropped more than 8%, led by catastrophic losses among major chipmakers and suppliers. Samsung Electronics fell nearly 10%, SK Hynix plunged 12%, and Taiwan Semiconductor Manufacturing Company dropped as much as 8.5% before hitting its daily limit-down circuit breaker.

According to RTE.ie, Japanese investor SoftBank Group slid 11%, while the cost of insuring against the firm defaulting on its debt jumped to a four-year high. European shares mirrored the downward trajectory, with the regional Stoxx 600 index declining 1.23% as losses spread across all sectors. CNBC reported that technology shares in Europe fell relatively mildly by 0.3%, but broader indexes suffered from simultaneous pressures, including rebounding oil prices and dampened diplomatic expectations following the US midterms.

Political Realignment and the End of the AI Bull Run

The market panic followed decisive Democratic wins in the US House and Senate during the midterm elections, injecting immediate regulatory uncertainty into an already overextended tech sector. Traders grew anxious that a newly empowered Democratic congressional majority would apply the brakes to the artificial intelligence boom, targeting high-energy data centers and tightening antitrust oversight. Donald Trump weighed in via Truth Social, stating that the stock market suffered one of the worst days in history and placing the blame squarely on Democrats, as highlighted by the Irish Examiner.

The selloff shows that AI stock prices had been built on rosy illusions about the future, and now that illusion is gone, said Dong Baozhen, chairman of asset manager Lingtong Shengtai, pointing out that the US stock market’s collapse has severed the backbone of the global AI bull run.

Underneath the political narrative lies a deeper structural anxiety regarding capital expenditure. Companies have poured hundreds of billions of dollars into AI-related infrastructure, yet institutional investors are increasingly questioning the timeline for meaningful cash flow generation. Neocloud firm CoreWeave, which CNBC and RTE.ie cite as a primary barometer for heavy AI borrowing and spending, slumped 10% amid widening concerns over tighter financial conditions and higher interest rates restricting smaller technology firms.

Margin Liquidations and the Main Street Portfolio Impact

As forced liquidations and margin calls swept through trading desks, retail investors and hedge funds alike rushed for the exits. Saxo chief investment strategist Charu Chanana warned that positioning made the adjustment exceptionally violent, noting that simultaneous unwinding becomes self-reinforcing when borrowed money is involved. Mega Financial Holding’s equities trading department vice president Allen Huang suggested to RTE.ie that heavy margin liquidations indicate the market is nearing the final stage of capitulation.

Because major market indices have grown heavily dependent on a handful of mega-cap technology stocks—such as Nvidia, which plummeted 9% and turned negative for 2026—weakness in the tech sector instantly translates into measurable shrinkage for household retirement wealth.

Market participants turned their attention to Friday morning’s October payrolls report for macroeconomic direction. The consensus estimate tracked by Dow Jones projected 59,000 jobs added and an unemployment rate holding steady at 4.2%. Whether that labor data can stabilize jittery bond and equity markets remains the central question as Wall Street attempts to price a permanent end to cheap-money tech speculation.
