Who Will Be the Ultimate Winners of the AI Wave? Investors Are Getting Pickier, Micron and Others Win Big Favor

 

Although massive capital continues pouring into AI infrastructure, after the initial frenzy of AI trading, investors are becoming far more selective. They are no longer blindly chasing every AI theme with a "spray-and-pray" approach, but instead focusing on one core question: Who will actually be the ultimate beneficiaries?

 

On one side are companies like CoreWeave Inc., an AI cloud service provider drowning in losses and debt. Its stock plunged 26% last week—its worst weekly performance since listing earlier this year—after dropping 22% the week before. Still, since its March IPO, the stock is up nearly 90%. On Monday, it fell another 2.6%.

 

On the other side are companies with solid profit outlooks like Micron Technology. Thanks to soaring demand for memory chips used in AI computing, Micron’s profits this year are expected to more than double. The stock hit an all-time high last week, up ~10% in November and ~180% YTD.

 

"The market is re-evaluating. Those companies that were once glamorous but lack cash flow are indeed taking hits," said Joe Tigay, portfolio manager at Rational Equity Armor Fund, which holds numerous AI stocks.

 

Since the start of the year, tech giants have accelerated investment, driving investors to pile into the AI theme almost indiscriminately and pushing U.S. stocks higher. Data shows that over the next 12 months, capital spending by Microsoft, Amazon, Alphabet, and Meta Platforms is expected to surge 34% to roughly $440 billion.

 

The difference now: Investors are paying much closer attention to stock quality. Companies with strong balance sheets are being chased, while highly speculative, heavily indebted names are being dumped.

 

Take Oracle as an example. Thanks to rapid growth in its cloud division, the traditional database software provider has soared this year. On September 10, its stock jumped 36% after forecasting that cloud revenue would reach $144 billion annually by the fiscal year ending May 2030—up from $18 billion this year.

 

Yet since then, Oracle shares have fallen 33%, as the market frets over the costs of fulfilling those commitments, which are increasingly financed through debt. The company’s free cash flow this fiscal year is expected to be negative $9.7 billion—the first negative reading since 1990—and is projected to worsen to negative $24.3 billion by fiscal 2028.

 

"Some companies are promising massive spending, but their cash flow situation isn’t ideal and they may need to borrow heavily to fund future investments. That worked when credit markets were calm, but the market is now increasingly focused on this potential risk," said Invesco Chief Global Market Strategist Brian Levitt.

 

Meanwhile, investor tolerance for massive AI investments without clear return paths is shrinking. After Meta’s Q3 earnings last month showed huge spending on expanding compute and hiring AI talent, its stock has dropped nearly 20% since—fears of a repeat of the "Metaverse debacle."

 

In contrast, Alphabet shares have kept climbing after earnings showed Google Cloud sales growth beating expectations—even as the company raised its full-year capex guidance. Alphabet is up nearly 60% in the second half of 2025, far outperforming the Nasdaq 100 and ranking among the index’s top 10 performers.

 

U.S. tech stocks have come under pressure recently, and it remains unclear whether this is just a temporary pullback or the start of a broader sell-off. Cetera Chief Investment Officer Gene Goldman, whose firm holds many key AI names, said the current selling is concentrated on companies with weaker balance sheets—reminiscent of the dot-com bubble.

 

"What’s really getting sold are the unprofitable, poorly regarded, weak players—because the market is gradually realizing who the real winners will be," Goldman said.

 

Even so, demand for AI services remains red-hot, with no signs of spending slowing in the near term. Investors are now laser-focused on Nvidia’s earnings after the close on Wednesday—the single most important bellwether in the AI space.

 

Given that huge sums are still flowing into infrastructure, Rational Equity Armor Fund’s Tigay remains convinced the AI trade has a bright future.

 

"I don’t think anything fundamental has changed in the space, but the market is re-evaluating and scrutinizing," Tigay said. "This is healthy."
