Cash is king as investors draw new battle lines in AI spending boom

In the wake of the AI spending boom, Wall Street rewarded Microsoft and Oracle on Wednesday for their ability to fund their ambitious AI projects without constantly relying on investor cash. Conversely, Alphabet faced significant penalties for its cash burn, while Google Search's sluggish growth raised concerns about the competition impacting its core business that drives AI expansion.

Microsoft shares surged over 3% in after-hours trading, while Alphabet plummeted nearly 10%, highlighting a clear distinction between companies profiting from AI and those grappling with its expenses.

This shift demonstrates that investors, who previously incentivized aggressive AI spending through debt, are now seeking more tangible proof that these investments can sustain future growth. Meta's recent earnings, which beat expectations but were marred by hefty cash burn, serve as a cautionary tale. Oracle, however, saw a nearly 11% boost in stock value after announcing plans to limit external financing and expect to turn cash flow positive in the second half of fiscal 2028.

The stark contrast between Microsoft's disciplined growth and Alphabet's cash-intensive approach, according to Melissa Otto, head of research at S&P Global Visible Alpha, may prompt investors to question whether AI is cannibalizing Google's core search business.
