Having established itself as an early leader in the market for cloud infrastructure, Amazon Web Services (AWS), the online retailer’s profitable cloud platform, is still ahead of the pack. According to estimates from Synergy Research Group, Amazon’s market share in the worldwide cloud infrastructure market amounted to 30 percent in the second quarter of 2025, ahead of Microsoft's Azure platform at 20 percent and Google Cloud at 13 percent. Together, the "Big Three" account for more than 60 percent of the ever-growing cloud market, with the rest of the competition stuck in the low single digits.
In Q2 2025, global cloud infrastructure service spending grew more than $20 billion or 25 percent compared to the second quarter of 2024, bringing total spending to $99 billion for the three months ended June 30. Looking at the full year 2025, cloud infrastructure service revenues look set to exceed $400 billion for the first time, explaining why the market is so fiercely contested. Despite its size, the cloud market is still growing strongly, with year-over-year growth even re-accelerating in recent quarters, mainly thanks to the AI boom and the computing requirements that come with it.
"This is a good time to be a cloud provider." John Dinsdale, chief analyst at Synergy Research Group said. "In Q2 we saw growth of 140-180 percent in GenAI-specific cloud services, and AI is also contributing to enhancements and added growth across the broader portfolio of cloud services."
