Might've changed since then, but Honnold is at a school appearance in Free Solo and a kid cheekily asks him if he's rich. He describes his financial situation as something like "a moderately successful orthodontist" which I wouldn't have thought would mean $1m in annual endorsements.
Honnold is one of the most humble dudes in the world (even about climbing, which he's very good at). I saw that clip too. I think he's made over $1mm/year since Free Solo came out, possibly just in endorsements/sponsorship. But he probably gives a lot of it away also, via his Foundation or other charities.
