💡 What is Magnus Carlsen's IQ?

This is the question most casual searchers ask first, so here is the direct answer.

Magnus Carlsen does not have a verified public IQ score. There is no confirmed official test result released by Carlsen or by a reliable official source, so exact numbers quoted online should be treated with caution.

The reason the question keeps appearing is easy to understand. Carlsen showed unusual memory at a very young age and later became the strongest player of his era. People naturally try to compress all of that into one number.

The better way to think about his strength is through chess skills that are visible on the board: pattern recognition, practical calculation, emotional control, opening flexibility, and the ability to keep asking difficult questions in equal-looking positions.

So when people ask “Is Magnus Carlsen a genius?”, the useful answer is yes in the everyday chess sense, but not because there is a publicly verified IQ score attached to his name.
