Technology companies are spending big to incorporate artificial intelligence into their businesses and to build huge data centers. Investors who had jumped on the bandwagon appear to be having second thoughts.
Proponents of artificial intelligence see it as the next great revolution for the global economy. The revolution won’t come cheap. Just four companies — Alphabet, Amazon, Meta Platforms and Microsoft — plan to spend up to $720 billion this year, primarily on AI data centers.
This week, investors are looking at the huge sums being spent and questioning whether AI can produce the profits and productivity necessary to make all the investment worth it. Critics have been talking about the possibility of a bubble in AI investment. On Monday, Amazon and Alphabet fell about 5%.
On Tuesday, several companies that make the chips needed for the data center buildup — Nvidia, Micron Technology, Broadcom and Lam Research — led the market lower.
At first, Microsoft, Alphabet and other so-called hyperscalers turned to cash on hand to fund the AI expansion. But they’re increasingly relying on the markets to raise cash.
AI buildout needs cash
Alphabet, the parent company of Google, said earlier this month that it’s raising $80 billion in cash to help pay for its investments by selling shares of its stock. Overall, Alphabet is planning to spend as much as $190 billion this year — more than all the stock of The Walt Disney Co. is worth, and Alphabet is forecasting its spending on investments next year will “significantly increase.”
In March, Amazon sold $54 billion of bonds in the U.S. and Europe as it plans to spend around $200 billion this year on AI investments.
Elon Musk’s rocket maker SpaceX was on a three-day skid heading into Tuesday. It regained some lost ground, but ended trading slightly below the closing price on its first day of trading on June 12. Musk acknowledges that SpaceX will have to spend heavily to fulfill its plans of sending AI data centers into space, and the company has announced that part of an upcoming bond offering will fund its AI buildout.
High-priced chip companies
Chip companies have benefitted as the demand for memory chips and processing power for AI data centers and other projects has led to a supply shortage and a surge in prices. Investors have bid up the share prices of these companies now in anticipation of big profits down the road. By one measure, which compares a company’s stock price to its earnings per share, these companies might look expensive.
Marvell Technologies lost money for five straight years before turning a profit of $2.7 billion in the fiscal year ended in January, thanks to gains in its data center business. The stock has more than tripled so far this year and its price-to-earnings ratio has gone from about 30 at the start of 2026 to near 100.
