The four biggest cloud and AI companies reported their quarterly results last week, and investors sold. Demand for AI was not the problem. The cost of meeting that demand was.
Here is what happened, and what it means if you pay for AI tools or plan to.
The Short Version
- Demand for AI cloud services keeps growing. Microsoft's Azure grew 48% and Amazon's AWS grew 39%.
- The bill grows faster. Amazon spent $77.3 billion on data centres and equipment in one quarter, more than double a year earlier.
- Three of the four now spend more cash than they bring in. Only Microsoft reported positive free cash flow.
- Investors want proof of return. Alphabet had its steepest one-day drop ever, and the Nasdaq fell 2.9% on Friday.
What Happened
Alphabet reported on Wednesday 28 October. Google Cloud revenue "more than doubled to $30.7 billion," CNBC reported (opens in a new tab). Free cash flow for the quarter was negative $9.07 billion. On Thursday, Alphabet's shares had their steepest one-day drop ever.
Amazon reported on Thursday 29 October. AWS revenue grew 39% to $45.98 billion. Capital spending reached $77.3 billion for the quarter, up from $35.1 billion a year earlier. Over the past 12 months, Amazon spent $42.4 billion more cash than it brought in, according to CNBC (opens in a new tab). Its shares fell more than 7% on Friday.
Microsoft was the exception. Its official results (opens in a new tab) show Azure revenue up 48%. The value of signed business contracts not yet billed grew 73% to $677 billion. Microsoft is the only one of the four still generating cash, with $18.63 billion of free cash flow, CNBC reports (opens in a new tab).
On Friday 30 October, the Nasdaq Composite fell 2.9% and the S&P 500 fell 1.8%, Yahoo Finance reported (opens in a new tab).
Microsoft's growth and spending figures come from its own release. The Amazon, Alphabet and Meta figures are reported: we took them from CNBC's coverage, because the companies' own releases did not load for us.
How Much They Plan to Spend
Each company plans to keep spending, and most plan to spend more next year:
- Amazon: about $220 billion in 2026. CEO Andy Jassy expects to "spend meaningfully more in 2027."
- Alphabet: $195 billion to $205 billion in 2026. CFO Anat Ashkenazi expects spending "to increase significantly in 2027."
- Meta: up to $145 billion in 2026. It also plans to raise $95 billion by selling new shares to fund AI.
- Microsoft: $39.4 billion on property and equipment last quarter, double the same quarter a year earlier.
Jake Behan of Direxion summed up the new mood to Reuters, as quoted by Yahoo Finance (opens in a new tab): "At this point, the market isn't just asking how fast you can grow. It's asking what you have to spend to get there."
What It Means for Your Business
Budget for Higher AI Prices
The companies selling you AI spend more on it than it earns them today. Their investors now want that gap closed. Some price rises are already announced. Google's Gemini 4 Carbon doubles in price after its launch period, as we covered in AI Radar #1. Plan your budget on the later price, not today's discount.
Keep a Second Provider Ready
Capacity is still tight. Gemini 4 Carbon launched for a small group of security teams only, with no date for wider access. Build your AI features so you can switch models without a rewrite. Test a second provider on your real tasks before you need it.
Ask Your AI Spend the Investors' Question
Investors now ask each company what its AI spending returns. Ask the same of every AI tool and project you run. Track the cost per task and the hours each workflow saves. Cancel tools your team stopped using. An AI audit does this across your business in one pass.
Don't Read This as AI Slowing Down
Cloud revenue grew 39% at AWS and 48% at Azure, and Google Cloud more than doubled. Businesses keep paying for AI in production. The pressure falls on the vendors' profit margins, not on whether the tools work. Waiting for the hype to fade carries its own cost: competitors keep automating in the meantime.
One Thing to Do This Week
List every AI tool and API your business pays for. Next to each one, write its monthly cost and what it would cost at double the price. If a price rise would wipe out a tool's value, line up a backup option now.
