Nasdaq drops 6%, Nikkei plunges in AI-driven sell-off

Nasdaq -6%: The AI hangover has a number

The Nasdaq lost 6% in a single session, while the Japanese Nikkei peine with a drop of more than 6%. It was no ordinary Tuesday: US tech stocks erased part of the rally that had taken them to highs, and the move spread to Asia before Europe even started trading. This decline trinc months of euphoria surrounding artificial intelligence and the data centers supporting it.

The quick explanation circulating in financial circles points to two culprits. First, political: some participants suggest the Democratic victory in the midterms triggered antiestéticars of stricter regulation on AI and data centers. Second, much more mundane: accumulated leverage in the sector, with ETFs and derivatives forcing rapid position unwinds when the market turns.

Domino effect crosses the Pacific

The Asian session confirmed this wasn't just a local scare. Japan's Nikkei index plunged over 6% at the open, and South Korea's Kospi trinc suit. When Tokyo and Seoul start deep in red, the narrative that "it's only Wall Street" collapses. The synchronized declines suggest the market was looking for any excuse to take profits.

Some argue this is an overreaction typical of an overheated sector. Others believe this is just the appetizer: every bubble inflates beyond possibility and always bursts, summarizes one of the most pessimistic views in investment forums. The debate over whether AI is a real revolution or a self-reinforcing holding company has been ongoing for months.

Leverage: the fine print nobody checked

The strongest technical argument emerging recently concerns leveraged products. With so many ETFs and derivatives in circulation, a moderate decline triggers a cascade of margin calls. Investors sell what they have on hand—including gold—to cover positions, accelerating the crash. Little hedging and almost everyone long: the classic recipe for panic.

The other pillar of the argument is fundamental. Real needs—housing, utilities, food, fuel—are extremely expensive, while companies focus on building data centers and selling subscriptions. The gap between what the stock market promises and what citizens demand is increasingly hard to sustain.

What happens to AI if Democrats regulate?

The political factor deserves its own section. The Democratic midterm victory has revived antiestéticars of stricter regulation on artificial intelligence and data centers. Some analyses suggest big tech will eventually lobby new senators and the scare will pass in days. Others believe the damage is done and the market has begun pricing in a tougher regulatory scenario.

What seems clear is that AI won't stop. If the US slows down, China will continue. The self-inflicted wound for the West would be monumental, as both Silicon Valley and Washington know. The question isn't whether there will be regulation, but how much it will cost and who pays the bill.

The 6% drop leaves a question hanging: is this the popping of a bubble or a simple correction in a sector with room to run? Data from upcoming sessions will show if bargain hunters enter aggressively or if the market is sicker than it appears. For now, the Nikkei has already given its verdict.
