The global cloud infrastructure market continues to grow at an aggressive pace, and fresh data from Synergy Research shows that momentum is reshaping the balance of influence among the sector’s biggest players. While Amazon Web Services keeps a firm lead, Microsoft, Google, and a new generation of AI focused providers are advancing with steady persistence, narrowing the gaps in ways that were far less visible only a few years ago.
Synergy’s report highlights a market that reached 107 billion dollars in spending during the third quarter of 2025, a number that reflects nearly 60 percent growth compared with the same period two years earlier. The expansion has benefited the entire cloud ecosystem, yet it has also revealed how fast competitors are moving. AWS secured 29 percent of global spend in Q3, but analysts point out that its share has edged downward since peaking in mid 2022. It is not shrinking in real revenue, but others are simply growing faster.
Microsoft reached 20 percent of the market, maintaining a quarter to quarter pattern that fluctuates yet consistently trends upward. Google climbed to 13 percent, and while still far behind the top two, it now commands nearly four times the share of Alibaba, the fourth largest global player. John Dinsdale of Synergy called it “striking” that AWS has held onto its position for so long, while acknowledging the speed at which Google and Microsoft continue to expand.
Outside the big three, a few notable shifts are taking shape. Oracle and several so-called neocloud providers are quietly gaining ground by focusing on GPU clusters and AI development environments rather than conventional cloud offerings. Besides CoreWeave, this new cluster of companies turning to the future is also led by Crusoe, Nebius, and Lambda, which are rapidly increasing their market share. IBM stands out as the only smaller provider losing share, dropping from five percent in late 2020 to roughly half that today.
The regional outlook adds further dimension. The United States remains the world’s largest cloud market and grew by 28 percent in the quarter, exceeding the combined total of the entire Asia-Pacific region. Meanwhile, India, Australia, Indonesia, Ireland, Mexico, and South Africa recorded growth rates above the global average, signaling that cloud adoption is widening faster than industry watchers previously expected.
