a real world version of this experiment: from time to time there is a hacking case where a criminal group steals earnings reports from companies before they are made public. some of these conspiracies have been quite profitable, but i believe all of them had at least a few trades go against them. a more extreme "crystal ball" were certain life insurance policies written by the French insurance company Aviva. They allowed customers to purchase shares today at last week's prices. This sounds incredibly stupid, but that's what the contract said, although the insurance company would like to get out of it. The legal battles have dragged on for a couple decades at this point.
