Cloud Market: AWS, Azure, and Google Further Expand Dominance

The cloud platforms of the three major tech giants Amazon, Microsoft, and Google have further expanded their shares in the rapidly growing global cloud market. This is according to figures from the consulting firm Synergy Research Group. Accordingly, Amazon's AWS, Microsoft's Azure, and Google Cloud now hold a 63 percent market share in the third quarter of 2025. Last year, this figure was still 62 percent, and 61 percent in 2023.

AWS, with a 29 percent market share, still holds the crown in the triumvirate; however, the Amazon subsidiary's top position has shrunk over the past few years. Azure with 20 percent and Google Cloud with 13 percent are slowly catching up. “Amazon's market share has averaged just under 30 percent over the last four quarters, down from just over 32 percent in 2021. The company's share is gradually shrinking as Microsoft and Google continue to gain ground, but it is still remarkable how effectively Amazon has maintained its leadership position,” commented John Dinsdale, Chief Analyst at Synergy Research, on the result.

Among the followers of the big three, Oracle stands out with gradual growth, and the so-called neoclouds with faster growth. The latter include providers like Coreweave, Nebius, Crusoe, and Lambda, who focus on GPU clusters and AI environments. However, the gap between the smaller competitors and the big three is enormous: “The reality is that the third-placed company, Google, is still almost four times larger than the fourth-placed company, Alibaba, underscoring the growing gap between the market leaders and the rest of the field,” says analyst Dinsdale.

Biggest Loser IBM

According to Synergy, both Alibaba and Salesforce have not grown as fast as the rest of the market despite good cloud revenues and have lost some ground. IBM has particularly suffered: its share has practically halved from a former five percent at the end of 2020. Big Blue's revenues in the cloud sector have essentially remained the same, and the company's focus is now elsewhere.

Overall, the global cloud market has continued its boom, reaching a revenue volume of 107 billion US dollars in the third quarter and 390 billion US dollars in the past twelve months, according to Synergy Research. The majority of the market consists of public IaaS and PaaS services, which together grew by 30 percent in the third quarter.

Geographically, the USA remains by far the largest cloud market, with a 28 percent growth in market volume in the third quarter. The markets in India, Australia, Indonesia, Ireland, Mexico, and South Africa have shown the largest increases. In Europe, Great Britain and Germany remain the largest cloud markets, with the highest growth rates in Ireland, Spain, and Italy.
