Amazon’s cloud business is still growing, but not as fast as Microsoft’s or Google’s — and that’s fueling fresh questions about its standing in the high-stakes race for generative AI dominance. While AWS remains the market leader in cloud infrastructure, the latest quarterly numbers suggest its rivals are accelerating faster.
AWS Growth Slows Compared to Rivals
In Q2, Amazon Web Services (AWS) revenue rose 17.5% year-over-year to $30.78 billion, beating forecasts but lagging far behind Microsoft Azure’s 39% surge and Google Cloud’s 32% jump. For context, AWS operates from a much larger revenue base, but the disparity still has Wall Street wondering if Amazon is losing ground in AI cloud workloads.
Synergy Research Group estimates AWS captured 30% of global cloud infrastructure spending in Q2, compared to 20% for Microsoft and 13% for Google. That’s down from AWS’s ~33% share just two years ago.
The Generative AI Factor
Much of the current cloud race is being driven by demand for generative AI capabilities. Microsoft has a high-profile advantage thanks to its deep partnership with OpenAI, while Google Cloud is winning traction among startups with its AI tools and infrastructure. Even Oracle — once dismissed as a cloud underdog — has landed major AI contracts, including its own deal with OpenAI.
Amazon is responding aggressively. It has invested $8 billion in Anthropic, an OpenAI rival, developed custom AI chips to lower processing costs for customers, and launched Bedrock, a platform that lets companies integrate their own data into foundation models. Yet analysts want to see these moves translate into faster AWS growth.
Jassy: “Still Early” for AI
On Thursday’s earnings call, CEO Andy Jassy pushed back on the idea that AWS is falling behind. “We’re at a stage right now where so much of the activity is training [AI models] and figuring out how to get your generative AI applications into production,” he said, arguing that AWS’s massive customer base and cost advantages will prove decisive over time.
However, he didn’t commit to a near-term growth surge. “I do expect that it’s going to get better each quarter, and I’m optimistic about that,” he told analysts. For now, Amazon is pouring money into expansion — spending $31.4 billion in capex in Q2, largely on new data centers, with similar spending planned for the rest of the year.
Why This Matters
The cloud market is the backbone of the AI boom, and AWS’s performance is a critical bellwether for the industry. While Amazon remains the largest player, perception matters — and investors are wary of a widening growth gap between AWS and its closest rivals.
If Amazon can leverage its AI investments, global infrastructure, and developer ecosystem to regain momentum, it could maintain its dominance. But with Microsoft and Google accelerating, the window to solidify AI leadership is narrowing.
