"Our friend dere in Burbank - You want I should pay him a visit?"
Barring an industry-wide move towards profit-based compensation, one wonders though why actors would agree to the higher risk/reward profile of back-end deals only to sell away their upside (a call-like cash flow) to Content Partners. The initial story by Jane Wells of CNBC stressed the difficulty and time involved with collecting the back-end profits from studios. Since the "enforcement" will largely fall to people already employed by the talent, which will just represent some incremental cost, this angle is only marginally convincing - to this Hollywood outsider at least.
Content Partners apparently has no plans to regularly sell the profit rights they buy. While a full-fledged secondary market would be interesting, it might create conflicts of interest. Likewise, the majority of deals will probably be hammered-out before money starts flowing in. As always, contract language is important.
Following Cuban's abandoned plans to start a sports-gambling hedge fund, some had speculated that he would become involved in prediction markets. While by no means a prediction market venture, Content Partners is certainly an innovative business, is obliquely reminiscent of HSX, and expands the set of tradable interests.
