Key Takeaways
- Google Cloud revenue hit $15 billion in Q3 2025, up 34% year-on-year
 - Now holds 13% global cloud market share, narrowing gap with Azure and AWS
 - Nine of world’s top ten AI labs run workloads on Google Cloud
 - Anthropic committed to one million TPUs in deal worth tens of billions
 
Once considered a distant third in the cloud wars, Google Cloud has transformed into one of Alphabet’s fastest-growing divisions, fueled by the AI boom and CEO Sundar Pichai’s long-term strategic vision.
Alphabet reported $15 billion in cloud revenue for the third quarter of 2025, representing a 34% year-on-year increase. This growth is primarily driven by demand for AI infrastructure, data centers, and Google’s in-house Gemini AI model.
“Google Cloud is one of the most important priorities for Alphabet,” Pichai told Reuters, emphasizing that the division’s role will only strengthen in the company’s next phase.
The Two Strategic Bets That Changed Everything
When Pichai became CEO in 2019, he identified YouTube and Google Cloud as his primary bets to diversify Alphabet beyond advertising. While YouTube grew into a global entertainment powerhouse, Google Cloud struggled initially, bleeding billions from 2018 to 2022 before achieving profitability in 2023.
The rise of generative AI has now validated Pichai’s patience. Under Thomas Kurian’s leadership, Google Cloud’s market share has nearly doubled, reaching approximately 13% of the global market according to Synergy Research Group. This narrows the gap with Microsoft Azure (20%) and Amazon Web Services (30%).
Cultural Transformation Drives Turnaround
Kurian implemented what insiders describe as an “un-Googley” cultural shift, moving from a loose, engineering-first approach to one focused on accountability and client satisfaction.
His cost-cutting measures included opening offices in North Carolina and Poland, revamping sales strategies to target specific industries, and renegotiating internal deals that had previously overcharged the cloud division.
Strategic Chip Move Pays Off
A pivotal moment occurred in 2022 when Pichai transferred control of Google’s TPU (Tensor Processing Unit) chips to the Cloud unit. This strategic move enabled Kurian to sell Google’s AI hardware directly to customers, including competitors.
Today, nine of the world’s top ten AI labs—including , Anthropic, and Safe Superintelligence—run workloads on Google Cloud. Anthropic’s commitment to one million TPUs alone represents a deal worth tens of billions of dollars.
The message for Pichai is clear: his long-term cloud investment has finally delivered substantial returns, positioning Google Cloud to potentially surpass YouTube in revenue contribution.
