AWS hits $37.6B revenue

Amazon’s cloud business is doing the thing investors wanted to see. AWS grew 28% year over year in the March quarter, reaching $37.6 billion in revenue, while Amazon’s total sales hit $181.5 billion. That is a big number on its own, but the real point is what it says about AI demand. Amazon has been pouring money into data centers, chips, and infrastructure, and this quarter gave the market a cleaner answer on whether that spending is actually turning into business. (ir.aboutamazon.com) ### Why is AWS the part everyone cares about? AWS is Amazon’s cloud unit — the business that rents computing power, storage, databases, and AI tools to other companies. It matters more than its share of revenue suggests because it throws off a huge amount of profit. In Q1, AWS(ir.aboutamazon.com)when AWS speeds up, it changes the whole Amazon story. (ir.aboutamazon.com) ### What actually changed this quarter? The headline is not just that AWS got bigger. It accelerated. Amazon said 28% growth was AWS’s fastest in 15 quarters, which means this was the strongest pace since the post-2022 slowdown in cloud spending started to fade. AWS also added about $2 billion of revenue sequentially from Q4 to Q1 — a jump management framed as the biggest Q4-to-Q1 increase in AWS history.

Training models and running inference chew through chips, memory, networking, and power. Amazon has been building around that demand with its own Trainium chips, Bedrock AI pla(ir.aboutamazon.com) helps explain why AWS growth is reaccelerating instead of flattening out. (fool.com) ### If growth is strong, why are investors still nervous? Because the bill is enormous. Amazon said trailing-12-month free cash flow fell to $1.2 billion from $25.9 billion a year earlier, mainly because purchases of property and equipment jumped by $59.3 billion. The company said that increase primarily(fool.com)y right now, with the promise that the payoff comes later. (ir.aboutamazon.com) ### So what are investors looking for now? They want proof that this spending is efficient, not just large. A company can always spend more on AI. The harder trick is turning that capex into durable revenue and margins before supply costs eat the upside. That is why AWS’s oper(ir.aboutamazon.com)ion in operating income is the part that calms people down. (ir.aboutamazon.com) ### Is there still a catch? Yes — capacity and component costs. On the earnings call, Andy Jassy flagged soaring memory costs, capacity constraints, and supply volatility. That means demand may be stronger than what Amazon can instantly serve, but it also means the infrastructure build-out stays expensive. Strong demand is good news. Expensive bottlenecks are the tax you pay for meeting it. (fool.com) ### What does this say about Amazon now? It says Amazon is looking more like an AI infrastructure company with a giant commerce business attached. Retail still matters, advertising still matters, but AWS is where the market is testing Amazon’s long-term bet. This quarter did not end that debate. But it g(fool.com)nue growth.

It is the first big sign in 2026 that Amazon’s AI build-out is translating into faster growth at the business that matters most. (ir.aboutamazon.com)
