How Big Is the CDN Market


It’s that time again, where we try to figure out the size of the global CDN market using sophisticated mathematics (adding). Trying to figure out the exact market size of the CDN industry is extremely difficult, since most private CDNs refuse to disclose annual revenues. However, that doesn’t mean we can’t give it a shot. Below is a ball park range of the annual revenues of the industry, which gives us a more complete picture. The most obvious known fact, Akamai commands 50%+ market share of the CDN industry. However, Akamai’s total percentage (not revenue) of the CDN market is probably shrinking in the single digits, due to the fact that more CDNs are entering the ecosystem and doing quite well in the “generating revenue” category.
