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

Wall Street has shown favor to Microsoft and Oracle for their ability to fund substantial AI initiatives without excessive reliance on investor capital, while Alphabet faced criticism for its rapid cash consumption. The shift in investor sentiment indicates they now seek concrete proof that the growth catalyzed by AI investments can sustain future expenditures.

Microsoft's stock surged over 3% in post-market trading, whereas Alphabet plummeted nearly 10% amid increased scrutiny. Meta experienced a similar outcome, with investors questioning its AI-related cash burn. In contrast, Oracle exited trading with a near 11% gain after confirming plans to limit external financing and achieving cash flow positivity in the second half of fiscal 2028.

Melissa Otto, head of research at S&P Global Visible Alpha, noted that Microsoft demonstrated prudent growth, while Google experienced significant cash consumption and below-market core business performance, potentially raising concerns about AI encroaching on its search revenue. Google's search revenue expanded by 12% in the September quarter but lagged expectations, falling short of a projected 14.7% increase.

The core business is under pressure from AI-driven alternatives, such as chatbots and agents, as search queries grow faster than anticipated. Alphabet's substantial capital expenditures, potentially reaching $205 billion this year, are benefiting Google Cloud, which saw a double-digit revenue increase to $30.71 billion; however, the company's cash burn reached $9.07 billion, marking its first quarterly negative cash flow since June.

Despite the heavy spending, Google's CFO, Anat Ashkenazi, emphasized the need for significant investments to maintain competitiveness in the rapidly evolving AI landscape.
