Why are Microsoft and Oracle highly sought after, while Alphabet has plunged nearly 10%? Cash flow is king

Cash flow has once again become king.

On Wednesday, Microsoft and Oracle demonstrated to the market that they have the capacity to fund massive AI investments without having to endlessly tap investors for capital—a realization that bolstered their share prices. In contrast, Alphabet faced a sell-off as it continues to burn through cash. A slowdown in the growth of Google Search has further fueled market concerns: is competition eroding the very core business that funds the company’s AI expansion?

Microsoft’s stock rose more than 3% in after-hours trading, while Alphabet’s shares plummeted nearly 10%. Investors are increasingly drawing a sharp distinction between companies that are successfully monetizing AI and those that are still struggling to keep costs under control.

In the past, companies that aggressively deployed capital—or even took on debt—to secure computing power were often rewarded by the market. Today, however, investors demand proof that such investments generate enough growth to cover the next round of spending.

Meta sounded an alarm last week; despite revenue growth that beat expectations and an optimistic outlook, the market remained fixated on the company’s high cash burn. Oracle, meanwhile, announced plans to cap external financing and projected that its free cash flow would turn positive by the second half of fiscal year 2028—a move that sent its shares up nearly 11% on Wednesday.

“It’s a night-and-day difference between Alphabet and Microsoft,” says Melissa Otto, head of research at Visible Alpha, a division of S&P Global.

“Microsoft showed very disciplined growth this quarter, whereas Google continues to burn cash, and its core business is underperforming expectations,” she noted. This has led investors to wonder whether AI is siphoning off market share from Google Search.

In the third quarter, revenue from Google’s search business grew by 12%—falling short of the 14.7% growth analysts had anticipated. Although CEO Sundar Pichai stated that search query volume is growing at its fastest pace in five years, the revenue generated has failed to meet market expectations.

AI-powered chatbots and agents are transforming how people seek information, posing a threat to what has long been a highly lucrative business—all while Google is forced to pour even more capital into AI. The company’s CFO informed analysts that capital expenditures are set to increase significantly by 2027. Cloud Revenue Doubles, Yet Fails to Keep Pace with Spending

Alphabet’s capital expenditures for this year are projected to reach as much as $205 billion—a staggering investment that has, in fact, fueled growth in another key AI-related business.

Google Cloud revenue more than doubled year-over-year to $30.71 billion, yet this growth has been eclipsed by massive spending. Following a negative free cash flow in the second quarter—a first for the company—the shortfall widened further to $9.07 billion in the third quarter.

Jeremy Saltzberg, a vice president and senior investment officer at Check Capital—which holds shares in Alphabet—remarked: “Google is truly a different company today than it was three, five, or ten years ago.”

He dismisses market concerns regarding the company’s spending, arguing that with rivals like OpenAI and Anthropic seemingly pulling ahead in the Silicon Valley AI model race, Alphabet must invest heavily to remain competitive.

“We believe this is a game that only those with deep pockets can afford to play,” Saltzberg said. “If you don’t have $150 billion to deploy in capital expenditures next year, you might as well not even show up.”

Microsoft: Expanding Infrastructure While Generating Cash

Microsoft presents a stark contrast. Despite investing $45.2 billion last quarter to expand its computing infrastructure, the company still generated $18.6 billion in free cash flow—nearly $10 billion more than Wall Street had anticipated.

Azure cloud revenue grew by 48%, exceeding expectations, and the company’s cloud growth forecast for the current quarter also surpassed market estimates—reflecting sustained, robust corporate demand for AI computing power.

The financial results also indicate that Microsoft is broadening its AI customer base, moving beyond a reliance on a small number of deep-pocketed clients with massive computational needs. Companies like OpenAI were previously the primary drivers of this industry expansion.

During an earnings call with analysts, Microsoft CEO Satya Nadella noted that an increasing number of enterprises are moving past the stage of merely experimenting with the latest, most powerful AI models; instead, they are beginning to sign long-term contracts. “The hype of just chasing the new, shiny object is fading,” he observed. He said, “What I’m after is a broader customer base. We have major clients who want to purchase from us—if the price is right, we might sell them some. If not, we’ll patiently build a business that serves a wider range of customers.”…
