November 2, 2026, (Inside AI) — A ferocious selloff in AI-linked stocks is raising fears that the technology boom, which has propped up the global economy, could tip major economies into recession. The S&P 500 has fallen 4% from its recent peak, while the Nasdaq is down 10%. Some Big Tech shares and AI-centric sectors have suffered double-digit declines, prompting investors to question whether the AI trade has peaked.
The stakes are high because AI investment has become a key driver of global growth. According to Adam Slater of Oxford Economics, AI-related effects boosted GDP growth across six advanced economies by an average of 0.2 percentage point in 2025-2026. Without these effects, underlying growth was only around 0.5%-1.0% a year. In the US, growth stood at 2.4%, but about a third of that was AI-related, Slater estimates.
Just as important are the wealth effects from high stock prices. The AI-fueled surge lifted US household net wealth as a share of disposable income to a record high. Stocks now account for almost 47% of US households' financial assets and 34% of total assets, both record shares. This has helped sustain consumer spending, the engine of US growth, at a time when elevated inflation and high energy prices might have curbed it. But wealth effects work in reverse too. A downward repricing of AI equities could generate a meaningful negative wealth effect, note Tiffany Wilding and Andrew Balls of PIMCO. Economists at Goldman Sachs estimate that the AI boost to US consumer spending growth from positive wealth effects was worth 0.4 percentage point, or 0.25% of GDP, over the past year. This impact was already expected to fade, but it could evaporate completely in a prolonged downturn.
Why a Recession Risk Is Real
The timing is precarious. Global growth risks for next year were already skewed to the downside. Domestic demand in China remains weak as the five-year property slump drags on. Beijing may struggle to post annual growth of 4.5%-5.0% next year, and a third year of record exports and a $1 trillion-plus trade surplus looks uncertain. Europe's outlook is shaky: political unrest and budget gridlock in France threaten to crimp euro zone growth, Germany is expected to grow around 1%, and Britain's 2027 outlook has just been slashed. Consumers and businesses globally are squeezed by high energy prices and borrowing costs. Brent crude closed at a six-month high on Friday, European gas prices are the highest in four years, US mortgage rates are well above 7%, and corporate borrowing spreads are widening notably, especially for lower-rated firms.
"The weakness of underlying growth across the advanced economies means that in the event of a serious slowdown in the AI boom - a genuine danger as we have recently argued -- the risk of advanced economies going into recession would be substantial," Slater wrote last week.
This dynamic is not entirely new. The dot-com crash of 2000-2002 wiped out $5 trillion in market value and contributed to a mild US recession in 2001. The current AI boom is larger in scale, with hyperscalers like Microsoft, Alphabet, Amazon, and Meta committing hundreds of billions to data centers. Unlike the dot-com era, today's AI leaders are profitable and cash-rich, which may cushion the blow. However, their spending is increasingly funded by debt, and the market's tolerance for rising capital expenditures is wearing thin.
The selloff has been exacerbated by a shift in investor psychology. Companies like Meta and Amazon are being punished for doubling down on big AI spending commitments. Yet if they were to cut spending projections, would their share prices rise? Unlikely. When all news is bad news, investors are getting restless. This suggests that the market may be entering a phase where good news is ignored and bad news is amplified, a hallmark of a turning point.
Some analysts see the selloff as a healthy correction within a longer bull run. They argue that the AI infrastructure build-out is still in its infancy, and the technology's productivity gains have yet to fully materialize. But others warn that the market's faith in AI has become a self-fulfilling prophecy, and any crack could trigger a cascade of selling. The Federal Reserve and other central banks have limited room to cut rates aggressively if growth falters, given lingering inflation pressures. Fiscal support is also constrained by high debt levels.
For now, the AI narrative and sentiment are clearly shifting. A total AI capex bust and complete market meltdown are both unlikely. But the risk of a serious slowdown is real, and it comes at a time when the global economy can ill afford it. If the selloff turns into a rout, the consequences could be severe.
