The Economics of the Cloud
Amazon, Microsoft, and Google hold 63% of cloud infrastructure spending. That is not the whole internet.
No survey shows that every person uses all three clouds every day.

What the data shows
A common claim is that three companies run the internet’s infrastructure, and that you use all three every day. The fact is the measured market is cloud infrastructure, not the internet. In the second quarter of 2026, Synergy Research Group put Amazon at 28%, Microsoft at 20%, and Google at 15%. That is 63% of spending on IaaS, PaaS, and hosted private cloud.
The quarter’s market was $143.4 billion, up 43% from a year earlier. Trailing twelve-month revenue was about $500 billion. In public cloud alone, Synergy said the top three held 67%. The rest of the market includes Alibaba, Oracle, and newer AI-cloud firms. Phone networks, undersea cables, and local internet providers are a different industry.
| Provider | Share of cloud spending, Q2 2026 |
|---|---|
| Amazon Web Services | 28% |
| Microsoft | 20% |
| 15% | |
| Top three combined | 63% |
| All other providers | 37% |
Synergy Research Group, Q2 2026. Cloud infrastructure services only. Not internet access or cable ownership.
How it was measured
Synergy counts enterprise spending on cloud infrastructure services: infrastructure as a service, platform as a service, and hosted private cloud. It does not count consumer phone bills, domain names, or every website. Shares are of dollars spent, not of servers or of users.
Other trackers use a different basket and get a different split. A firm can sell ads or office software and also rent cloud. Daily use of Gmail, Office, or Amazon shopping is not the same as using that firm’s cloud. Synergy does not publish a count of people who touch all three clouds in a day.
What it means
It is settled that three firms take most cloud infrastructure spending, and that the market grew 43% in a year. It is not settled that they run the internet, or that each person uses all three every day. Use 28%, 20%, and 15%. Do not use “the internet.”
Common misreadings
- This figure is not ownership of the internet. It is a share of cloud infrastructure spending.
- This does not include every network. Access providers and cable owners sit outside the Synergy market.
- A change from 30% to 28% for Amazon is a share shift inside a market that grew 43%, not a fall in dollars.
