Who is it this time?
It's Tyler Cowen, who is an actual professor of economics and an actual chess player
and should therefore know better. But he doesn't.
No, he hasn't made the claim himself: but he's reported it, uncritically, without so much as a link to support it and without so much as a word to cast doubt on it.
Which is something, I reckon, he shouldn't do, either as a chess player or a professor of economics.
So why did he?
Let's ask him.

Dear Professor Cowen
Sorry to bother you. My name is Justin Horton, I'm a chess blogger and among the subjects I have written about is the claim that there are 600 million chess fans in the world.
As this claim is manifestly nonsensical (where are they all hiding?) and no evidential basis appears to exist for it, I was very suprised to see your Bloomberg Opinion piece say the following:
Worldwide, chess claims about 600 million fans, which makes it one of the most popular games or sports.At no point do you appear to question this claim, or qualify it, or provide any evidence to back it up. I wondered if there was any reason why not. I also wonder whether you would agree that when people read a Bloomberg piece written by a professor of economics, they are entitled to assume that the facts and figures contained therein can be relied on.
All the best
