Which Is the Largest Hosting Company in the US?
There’s no single largest US hosting company without defining the measure. In CronDB’s US small-business website sample for the week of November 2, 2026, 19.9% pointed to AWS networks and 21.2% pointed to Cloudflare. A public network can sit in front of the company that hosts the site.
The key distinction is between the company serving the public address and the one operating the underlying site.
Compare Web Hosting ProvidersWhat the US Numbers Can Tell You
CronDB grouped public website addresses by the network that owns them across 766,391 US business websites. That can reveal where requests first go. It doesn’t give a complete count of companies that sell or operate the underlying hosting.
How to Define Largest
If you mean the largest US-headquartered company, you also need to pick a metric such as hosting revenue, customers, or websites. Company-wide cloud revenue measures more than small-business web hosting.
