Considering chess are played worldwide, chess.com still can grow. When will chess.com go public? Can I buy a share? How much is it? What is ROI?

The number of players ranked in online chess is 356,979. That is much less than 7.000.000, but still a lot of players.
There are also players that do not play online chess and will appear only in the statistics of bullet or blitz or chess960. I am wondering how many current accounts chess.com has. Does anyone know?

in Europe 18,404 is a bit more than 18 people and 18.404 is 18k+ people.
Wait... really?
In continental Europe... In Britain, it's also 18,404 to mean 18+ thousand. I teach English in Europe (continental), and have to mention this point.
Thats the highest I have ever seen!
World championship + winter in the western world + evening/daytime in western world = peak
I suppose. Chess.com is growing I think. The year before I saw 15 or 16.000 people online. I'd love to see some 'official' stats about this.
