How many people watch esports worldwide?

How to get close to this number

Anchor on a sport you can size. The explanation offers one directly: the audience is comparable to that of a major basketball league. Anchoring an unfamiliar quantity to a familiar one in the same category is almost always better than estimating it cold, and sports audiences are quantities most people have some feel for.

The definition is doing enormous work here, and it is where the scepticism belongs. "Watches at least occasionally" is a very wide net — it includes someone who saw a tournament clip once this year. Engagement statistics from market research firms are usually built on survey self-reports with generous thresholds, which is how audience figures for emerging categories get large fast.

The prize pool detail in the explanation reveals the economics. The largest purses are funded partly by in-game item sales, meaning the audience directly finances the prize money by buying cosmetics. That is a fundamentally different model from broadcast rights and sponsorship, and it is why esports economics do not map cleanly onto traditional sports.
