Man, something like this is going to be a plot point in a movie/tv series soon.

Could work in some crime procedural.

This is an old plot, done already in dozens of different variations.

I think there are lots of plots that revolve around rigging sports betting (e.g. sub-plot in Pulp Fiction), but I can't really think of a case where it is not so much about manipulating the actual act that occurred, but rather the news reporting of the act.

Bond's Casino Royal had a stock short sell bet with a planned attack.
