Fantex is an investing platform that allows you to buy shares of professional athletes. In addition to owning a small stake in an athletes' future earnings, Fantex contracts also provide the option to co-invest in an athlete's personal investments. So if you are interested in owning a piece of Jamba Juice, just invest in 49er tight end Vernon Davis.
But Fantex’s contract with each star includes another right that, until now, it had not exercised: the ability to hop aboard with any personal investment the athlete chooses to make. Vernon Davis, whose stock was the first that Fantex took public, in April 2014, already owned a Jamba Juice franchise location in Santa Clara, California, that is branded with his name and opened in 2013. Now he is buying three more locations, all in California, and Fantex is co-investing with him at a 10% stake in each. (When it signed Davis, it paid him $4 million for a 10% stake in his future endeavors.)
