Why Did the AI Stock Sell-Off Wipe Out US$2.5 Trillion?

The tech-heavy Nasdaq index has officially entered a correction, falling around 12% over the past month. That wiped US$2.5 trillion in market valuation for Nasdaq companies alone.
Heavy selling on Wall Street on Thursday followed the Democratic wave in this week’s midterm elections. Investors feared a regulatory crackdown on AI infrastructure.
How Big Is AI Data Centre Spending in the US Economy?
Data centre outlays contributed 30% of US growth in 2025 and 2026, according to Bruno Cavalier, economist at Oddo BHF. Spending on data centres surged 150%.
Power sources, intensive cooling systems and construction, plumbing and electrical work all bring money and jobs to local communities. Opposition is building over air pollution, higher energy costs, water use and noise.
Who Is Exposed if US Stock Prices Keep Falling?
Cavalier said 43% of US household wealth is now exposed to the stock market, up 10 percentage points from 2000. Retirees face the most direct hit to their spending power.
Alexandre Baradez of IG France said the richest 10% of Americans now account for half of consumer spending. They own the most stocks and gained the most from tech rallies, so a market crisis could curb their spending too.
Why Do Higher Interest Rates Hurt AI Borrowers?
Rising rates lift borrowing costs on the billions of dollars of debt AI firms have taken on to build data centres. Baradez said there is little chance of any easing moves soon by central banks.
Tighter financial conditions could make investors wary of putting in more money. Analysts note that the same pressure could push some investors to cut sector exposure.
Will Regulation Slow AI Data Centre Construction?
Kevin Thozet of Carmignac said markets are pricing in the risk that Democratic victories in the states with the most projects will make construction more expensive and longer to complete. Jacques-Aurelien Marcireau of Stilgar expects no general halt, saying Democrats will be pragmatic.
Marcireau added that a slowdown ‘could even be healthy, by halting the most vulnerable projects’. Investors may want to watch which projects fall into that category.
Can Anthropic Still Raise US$100 Billion in Its IPO?
Claude-maker Anthropic had reportedly been looking to raise US$100 billion this month, which could have valued it at up to US$2 trillion. It may now have to settle for less.
Rival OpenAI has already pushed back its IPO plans to sometime next year. Baradez said, ‘Anthropic will be the big test.’ Readers following the offering can compare tools in AI Stock Analysis for Malaysians.
What Does This Mean for Bursa Malaysia Investors?
The AFP report names no Bursa-listed company, so no local share prices or earnings can be drawn from it. The channel to watch is global tech sentiment and the pricing of the Anthropic IPO.
Individuals pay no capital gains tax on shares listed on Bursa Malaysia. Bursa trades settle on T+2.
