The continued growth of the digital advertising market became much stronger despite broader economic uncertainties. Both Alphabet and Microsoft reported strong quarterly earnings this week.

Alphabet, Google’s parent company, reported a 13% incline in advertising revenue. On the other hand, Microsoft registered a 16% jump in search and news ad revenue, reflecting intensified competition and rapid advancements in AI-driven search experiences.

Google’s Record-Breaking Quarter

Alphabet’s Q3 2025 results marked the company’s largest revenue quarter ever, reaching $102.3 billion, up 16% year-over-year. Advertising revenue accounted for $74 billion, climbing 13% compared to the same period last year.

CEO Sundar Pichai described the results as a milestone moment:

“Alphabet had a terrific quarter, with double-digit growth across every major part of our business. We delivered our first-ever $100 billion quarter.”

Key highlights from Google’s report include:

  • YouTube Advertising Revenue: $10.26 billion (vs. $10.01 billion estimated)
  • Google Cloud Revenue: $15.15 billion (vs. $14.74 billion estimated)
  • Traffic Acquisition Costs (TAC): $14.87 billion (in line with estimates)
  • Earnings per Share: $2.87

Alphabet credited its AI-powered Search innovations — particularly the AI Overviews and AI Mode features — for driving a surge in user engagement and query volume.

According to the company, AI Mode queries doubled over the quarter, and more than 100 AI-driven improvements were rolled out in Q3 alone, contributing to “incremental total query growth.”

Microsoft’s Ad Revenue Keeps Climbing

Microsoft’s Q1 fiscal 2026 results also painted a strong picture. Total company revenue rose 18% to $77.7 billion, with operating income up 24% to $38 billion.

The company’s search and news advertising segment, which includes Bing and MSN, delivered 16% year-over-year growth (15% in constant currency) — a slight slowdown from the previous quarters’ 21% growth streak but still a robust performance.

CEO Satya Nadella attributed the gains to Microsoft’s growing AI ecosystem:

“Our planet-scale cloud and AI factory, together with Copilots across high-value domains, is driving broad diffusion and real-world impact. It’s why we continue to increase our investments in AI across both capital and talent to meet the massive opportunity ahead.”

Highlights from Microsoft’s report:

  • Net Income: $27.7 billion (GAAP) — up 12%
  • Non-GAAP Net Income: $30.8 billion — up 22%
  • GAAP EPS: $3.72 (+13%)
  • Non-GAAP EPS: $4.13 (+23%)

Executives also noted that Bing’s new overview pages now integrate embedded conversational AI features — similar to Google’s AI Overviews — and confirmed that “Bing took share again in search,” signaling ongoing market traction.

The Bigger Picture: AI-Powered Search Reshaping Ad Markets

The concurrent growth in both Google’s and Microsoft’s ad revenues underscores how AI integration is fueling a new wave of monetization opportunities in search and content discovery.

As both tech giants weave generative AI more deeply into their platforms, advertisers are seeing expanded formats and higher engagement rates.

With both companies reporting double-digit gains and record-setting revenues, the digital advertising landscape appears to be entering a new era — one where AI not only enhances search relevance but also drives measurable financial performance.
