Forget billionaires, even hedge fund managers who actively trade Tesla may not be registered here. They will ask an intern to scan TMC. Bigger ones will hire people like SoylentBrown to do in depth investigation and likely have a lot more info than we do.
Based on the returns of hedge funds it is unlikely that they have a lot more information than we do. Frankly their continuing existence is amazing, but then again we've known that actively managed mutual funds are generally terrible for years and they still exist.
