Quickly Googling about, a commonly repeated figure is that Akamai served 15% - 30% of Internet traffic in the late 2010's. They probably have less of the market today due to others growing, but they're not a minnow.

2024 revenue figures were $1.669 billion for Cloudflare, and $3.99 billion for Akamai, per Wikipedia.

> 20% of internet traffic passes through CF networks

That does not sound right to me. “20 percent of websites” does not mean “20 percent of traffic.”.

There is no public write-up from Cloudflare that proves “we handle 20% of all Internet traffic.” Cloudflare reports around 295,000 paying customers and more than 30 million Internet properties (20% of the web). So most of their users are on the free plan.
