AWS just posted its fastest growth in 18 quarters while Google Cloud surged 82% year over year, and both companies are spending tens of billions to pull further ahead. But when forced to pick one, the numbers point decisively in…
Amazon (NASDAQ: AMZN | AMZN Price Prediction) and Alphabet (NASDAQ: GOOG) both dropped Q2 2026 numbers that reshuffled the AI infrastructure hierarchy.
AWS posted its fastest growth in 18 quarters, while Google Cloud rocketed 82% year over year. Both are pouring tens of billions into chips, data centers, and models. If you can only own one, the differences below matter more than the shared headlines.
Cloud Reaccelerates for Both, but One Is Pulling Away Faster
Amazon reported Q2 revenue of $200.61B, up 19.6% YoY, with AWS at $42.23B and a 39.4% operating margin. CEO Andy Jassy said “AWS is booming, growing 36.7% year-over-year in Q2, our fastest growth in 18 quarters, and our AI and Chips businesses each eclipsed run rates of more than $25 billion.”
Backlog sits at $496 billion. Retail is quietly re-accelerating too, with Advertising up 26% and Amazon Now gross sales growing 80%+ QoQ.
Alphabet posted $119.8B in revenue, up 24.2% YoY, its 12th straight quarter of double-digit growth. Google Cloud hit $24.77B with operating margin expanding to 35.6% from 20.7% a year earlier. Backlog reached $514 billion.
Sundar Pichai told investors “Q2 was an amazing quarter, with Alphabet revenues growing 24% year-over-year and Google Cloud revenues accelerating to 82% growth.” Search still grew 17% despite AI Overviews fears.
| Business Driver | Amazon | Alphabet |
| Cloud growth | 37% | 82% |
| Cloud backlog | $496B | $514B |
| Q2 capex | $54.21B | $44.92B |
| Operating margin | 13.7% | 34% |
Two Very Different Bets on the Same AI Boom
Amazon is spreading its bets across a sprawling stack: Trainium silicon with multi-year, multi-gigawatt commitments from Anthropic and OpenAI, Bedrock as a model marketplace, Zoox robotaxis, and nearly 400 Amazon Leo satellites. Qualcomm just handed Amazon $4 billion in warrants as part of an AI infrastructure deal, another vote of confidence in AWS scale.
Alphabet is going full-stack and vertical. Gemini has 950 million MAUs, processes 22 billion tokens per minute, and is embedded in nearly 90% of Fortune 100 companies via Gemini Enterprise. Waymo crossed 500,000 fully autonomous rides per week.
The tradeoff: Alphabet suspended its buyback in Q2, raised $70B in equity and debt, and long-term debt jumped from $46.5B to $98.2B. That is a lot of funding pressure for a company that used to print cash effortlessly.
What I Am Watching Into Year-End
For Amazon, Q3 guidance calls for $197B to $202B in revenue and $22.5B to $26.5B in operating income. I want to see AWS margins hold above 35% while capex keeps climbing.
For Alphabet, the tell is whether Search revenue keeps compounding as AI Overviews expands, and whether third-party capacity brought in as a bridging strategy squeezes Cloud margins in Q3.
Why I Would Pick Alphabet Today
On the numbers, Alphabet screens more favorably today. It trades at a P/E of around 17 versus Amazon’s 21, generates a 32% operating margin, and just showed Cloud can accelerate and expand margin at the same time. The stock is also up 37.22% over the past year compared with Amazon’s 5.94%, and analysts still see room to run toward $422.34.
Amazon remains the more diversified compounder, with lower embedded expectations that some turnaround-oriented investors may find appealing. For me, Alphabet’s cash engine plus Gemini distribution wins the coin flip.
