In the real market, contracts on the Cantor exchange will trade at $1 for every $1 million a movie is expected to bring in — a figure determined by traders — at the domestic box office during its first few weeks in theaters. So if “Robin Hood” is expected to bring in $100 million in its opening weeks, a single contract could be bought for $100 by a trader who thinks Russell Crowe’s role in the movie will drive sales far above expectations. If that trader guesses right, and the movie sells $150 million in tickets, the trader makes $50.

"A new law has been enacted by Congress that bans trading of futures contracts based on motion picture box office receipts, which was the first contract that Cantor Exchange had anticipated making available to its participants. This legislation has caused us to postpone any trading of box office receipt contracts for an indefinite period of time." Source: Cantor Exchange - Home

Usually this means some group with political pull got this law passed. Does anyone know who stands to benefit from this? Is this just Wall Street nipping some potential competition in the bud or did someone in Hollywood have a reason to shut this down? Curious if anyone knows the motivations behind killing this idea.
