Methodology problems aside, do we have any idea how big OpenRouter is as compared to the big providers?

OpenRouter claims "5M+" users; OpenAI is claiming >900M weekly active users.

I don't really think it's possible to learn anything about the broader market by looking at the OpenRouter model rankings.

Agreed it's not really good signal (many sampling biases) but user count is not relevant, most money is from heavy API users. 900M users with free or cheap subscription are nothing compared to even 10k heavy API users.

On the other hand, big users don't use openrouter. At $work we have our own routing logic.
