Amazon's Q2 Earnings: Can It Match the AI-Driven Cloud Growth of Microsoft and Google?

The race for AI dominance is heating up, and cloud computing is the battlefield. As Amazon prepares to report its Q2 2025 earnings, the question on investors' minds is whether AWS—the backbone of Amazon's profitability—can keep pace with Microsoft's Azure and Google Cloud, both of which are pouring billions into AI infrastructure. With AI now the linchpin of enterprise software, the cloud providers' ability to monetize this transformation will determine their long-term valuations. Let's dissect the numbers, strategies, and risks for each player.

The Cloud Growth Playbook: Amazon vs. Microsoft vs. Google

Amazon Web Services (AWS) is expected to report $30.7–30.8 billion in Q2 revenue, up 16.9–17.4% year-over-year. This aligns with its Q1 performance, where AWS achieved a 39.5% operating margin—the highest since 2014. However, analysts project a drop to 35% in Q2 due to capital expenditures on AI infrastructure, including custom chips like Trainium2 and partnerships with Nvidia. Amazon's 2025 capex plan exceeds $100 billion, with a significant chunk allocated to AI and cloud expansion.

Microsoft's Azure, meanwhile, is outpacing AWS in growth. For fiscal Q4 2025 (calendar Q2), Azure revenue hit $75 billion for the year, a 34% year-over-year surge. Microsoft CEO Satya Nadella has called Azure “the leader in the AI infrastructure wave,” with AI-powered tools like Copilot now boasting 800 million monthly active users. Microsoft's capex for the year is $88.2 billion, with plans to hit $120 billion in 2026. This aggressive spending reflects its dual focus on cloud scalability and AI integration.

Google Cloud is not far behind. Its Q2 capex reached $22.4 billion, and it maintains a $50 billion annualized revenue run rate. Alphabet executives, however, have warned of supply chain constraints through 2025, a headwind AWS may avoid due to its diversified AI chip strategy.

AI Infrastructure: Who's Winning the Long Game?

Amazon's bet on AI is bold but capital-intensive. Its $100 billion 2025 AI capex dwarfs Google's and Microsoft's current spending, but it comes at the cost of near-term margin compression. The company's recent innovations—like S3 Vectors (a 90% cheaper AI storage solution) and Amazon Bedrock AgentCore—are designed to lock in enterprise clients for the long haul. Yet, Microsoft's ecosystem advantage (e.g., Azure's integration with Office 35 and LinkedIn) and Google's AI research prowess (e.g., Gemini models) pose stiff competition.

Microsoft's CFO, Amy Hood, has framed AI monetization as a “software-like” opportunity, with pricing models tied to usage and user tiers. This approach aligns with its broader strategy to embed AI into every layer of its stack. Google, meanwhile, is betting on its “AI-first” hardware (TPUs) and enterprise partnerships to close the gap.

Valuation Realities in the AI Era

Amazon's stock has lagged its peers in 2025, up just 5% year-to-date compared to Microsoft's 20% and Google's 15% gains. Part of this underperformance stems from investor skepticism about AWS's ability to maintain its margins while funding AI growth. Microsoft's stock, however, trades at a P/E of 38, reflecting confidence in its recurring revenue and AI monetization. Google's P/E of 28 suggests a more cautious outlook, given its ongoing market share challenges.

The Risks and Rewards of the AI Cloud Race

For Amazon, the key risk is whether its AI investments can translate into sustainable margin expansion. If AWS's operating margin stabilizes above 30% by 2026, it could justify the current valuation premium. Conversely, if margins fall further, investors may question the trade-off. Microsoft's Azure, while growing faster, faces the same scrutiny: Can it maintain profitability while outspending its rivals? Google's supply constraints and slower enterprise adoption of its AI tools add another layer of uncertainty.

Investment Implications

Amazon's Q2 earnings will serve as a litmus test for its AI strategy. A strong AWS performance—particularly if it reaffirms the $100 billion capex plan and shows progress in AI monetization—could reignite investor enthusiasm. However, given Microsoft's ecosystem advantages and more mature AI integration, it remains the safer bet for long-term growth. Google, while undervalued relative to its AI capabilities, may require patience to see its strategy bear fruit.

For now, the cloud race is far from over. Amazon has the resources and technical depth to compete, but execution will be everything. Investors should watch AWS's operating margin trajectory and the pace of AI-driven revenue growth in Q2. If Amazon can prove that its AI investments are paying off, it could still close the gap with Microsoft and Google—and redefine the future of cloud computing.
