Cloud Overtakes Search as Growth Engine

For the first time in Google's 27-year history, its cloud-computing business has emerged as the primary driver of growth, posting a 63% revenue increase to $20 billion in the first quarter. The unit's operating income tripled to $6.6 billion, while its operating margin soared from 9.4% to 32.9%. Alphabet's shares jumped 10% on Thursday, capping a 34% monthly gain — the best since October 2004, shortly after Google's initial public offering. The rally came as investors rewarded the company for delivering better-than-expected results, fueled by insatiable enterprise demand for artificial intelligence solutions.

AI Spending Plans Diverge: Alphabet Rises, Meta Falls

While Alphabet's stock surged, Meta shares plummeted nearly 9% in their steepest drop since October, despite the social media company beating earnings and revenue estimates. The divergence highlights Wall Street's selective appetite for AI capital expenditure. Alphabet raised its 2025 capital expenditure forecast to between $180 billion and $190 billion, up from a prior range of $175 billion to $185 billion. Meta, meanwhile, increased its capex plans to $125 billion–$145 billion, citing higher component pricing and additional data center costs. To fund the buildout, Meta is marketing a $20–$25 billion bond deal, its second in seven months, with Goldman Sachs and Morgan Stanley managing the transaction.

The Cloud's Cultural Earthquake Inside Google

The rise of Google Cloud is not merely a financial shift but a cultural one. The cloud division is led by Thomas Kurian, an Oracle veteran who presides over a sales force in suits — a stark contrast to Google's traditional sandal-wearing engineers and product managers. As cloud revenue approaches one-fifth of Alphabet's total — up from 13.6% a year ago and 11.8% in early 2024 — the tension between these two cultures is likely to intensify. The change could have profound implications when the time comes to choose a successor to CEO Sundar Pichai.

Advertising Still Dominates but No Longer Defines the Company

Google's advertising business remains formidable, generating $77 billion in the first quarter — more than American Express earned in all of 2025 — and growing 16% year over year. Many analysts believe AI will further enhance ad targeting. Yet the cloud unit's accelerating growth has reached an inflection point. At 18% of total revenue, it is on track to account for one-fifth of the empire within two quarters — a milestone that would have been unthinkable just a few years ago.

A $460 Billion Backlog and the Risk of an AI Slowdown

Google Cloud's current backlog stands at $460 billion, reflecting insatiable customer demand for AI infrastructure. CEO Sundar Pichai attributed the cloud surge to enterprise AI solutions. However, the cloud business's fortunes remain tethered to the AI boom. If the AI train slows or halts — a scenario many observers consider possible — Google Cloud could find itself relegated to second-class status once again. The company's revised capex forecast of up to $190 billion underscores the high stakes.

Wall Street's Uneasy Truce with AI Spending

The contrasting market reactions to Alphabet and Meta reveal that investors are still calibrating the balance between AI opportunity and the cash required to chase it. As Matt Britzman, an analyst at Hargreaves Lansdown, noted, "the bigger takeaway is that this cycle is nowhere near cooling." Meta's lack of a cloud business makes it harder to prove returns on its AI investments, while Alphabet's cloud unit provides a tangible revenue stream. The bond market is also taking note: Meta's second debt deal in seven months signals that even profitable tech giants need external financing to sustain the AI arms race.

The bottom line

• Google Cloud's 63% revenue growth and tripled operating income have made it Alphabet's primary growth driver, reshaping the company's identity beyond search and advertising.
• Alphabet's stock surged 34% in April, its best month since 2004, while Meta's shares fell 9% as investors penalized AI spending without a cloud revenue offset.
• Alphabet raised its 2025 capex to $180–$190 billion; Meta increased its own to $125–$145 billion and launched a $20–$25 billion bond deal.
• Cloud now represents 18% of Alphabet's revenue, up from 11.8% a year ago, and is on track to reach 20% within two quarters.
• The cloud unit's operating margin expanded from 9.4% to 32.9%, reflecting rapid scaling and profitability.
• Google Cloud's $460 billion backlog underscores intense AI demand, but a potential slowdown in AI investment could reverse the unit's ascent.
