I think he became A rich man (Not sure if he is still the richest) by working hard and creating companies that benefited greatly from government contracts and subsidies. The whole "Inflation has peaked" statement may be nothing more than an attempt to curry favor or mend fences with those same entities after getting into hot water with his recent controversial political statements.
What he observes and acts on, and what he says publicly are not necessarily exclusive. Not saying he's misleading anyone here, but it's not unlike him to say something publicly to benefit himself.
