Investors are pushing back hard against Big Tech’s aggressive artificial-intelligence spending plans, causing shares of the “Magnificent Seven” companies to fall dramatically.

After eight consecutive days of losses, shares of Amazon.com have officially tumbled into a technical bear market, meaning that they’re off 20% or more from their recent high. Amazon’s stock closed at $199.60 on Thursday, 21.4% below its recent high.

Among the four major hyperscalers, Amazon has the highest amount of planned capital expenditures for 2026, at $200 billion. Amazon, Microsoft, Meta Platforms and Alphabet are expected to spend a cumulative $650 billion on AI capex in 2026.

Amazon joins Microsoft as the second “Magnificent Seven” name that’s fallen into bear-market territory. Shares of Microsoft entered a bear market on Jan. 29, one day after the company reported Azure cloud growth that fell short of investors’ expectations. As of Thursday’s close, Microsoft’s stock is down 25.9% from its recent high.

Meta looks positioned to be next, as shares are 2.3% away from reaching bear-market territory, according to Dow Jones Market Data. While Meta’s fourth-quarter revenue and earnings results beat Wall Street’s expectations, increased AI spending and margin pressure have weighed on investor sentiment.

The recent selloff highlights a growing rift between members of the “Magnificent Seven,” Mike Treacy, vice president of risk at Apex Fintech Solutions, told MarketWatch.

Since the fall, investors have rotated out of the OpenAI trade associated with names like Microsoft, Nvidia and Oracle amid rising concerns over circular financing deals. Instead, they’ve begun favoring the Alphabet and Broadcom ecosystem, Treacy said.

Alphabet’s vertically integrated tech stack has offset some of the overspending fears and shielded the stock from the worst of the tech selloff, Treacy added. Shares of Alphabet closed on Thursday down 9.2% from their recent high.

“I do think Google’s self-sufficiency should command a premium relative to the others that could be adversely impacted by one cog in the wheel,” Treacy said, referring to Google’s proprietary tensor processing units.

On the other hand, shares of Amazon, Microsoft and Meta are being hit harder as investors are less confident about those companies’ abilities to deliver a sufficient return on investment on their AI spending. For Amazon, increased capex levels could push its free cash flow into negative territory this year, meaning that it would need to start tapping the debt markets to raise more capital.

The next big catalyst for the AI trade will be Nvidia’s earnings report on Feb. 25, according to Treacy. The results will show whether the AI boom is cooling, or if Nvidia is successfully capturing the billions its biggest customers are pouring into the trade.
