This is a difficult question to answer definitively because Bezos' exact net worth is not publically known. However, we can make some estimates based on the known value of Amazon and his other holdings.
According to Forbes, Bezos is worth an estimated $143 billion as of March 2020. Given that Amazon's stock price has increased significantly since then, it is safe to say that his net worth is even higher now.
Assuming that Bezos' net worth has remained constant since March 2020, that would mean he is earning about $394 million per day. Of course, this is just an estimate and the actual figure could be higher or lower.
