Let's say that you, zem, are an expert player and you have entered a roster into DraftKings Million Dollar contest. I, swanson, am an employee of DraftKings and have access to your lineup and/or data about all the other lineups entered. (* This is speculation) I, swanson, then use this inside knowledge to make my own lineup on FanDuel (I am not allowed to play on DraftKings because I work there). I win big money on FanDuel. --- The results of the NFL games are not the inside information, but rather the game theory-esque information about the decisions made by other parties in a zero-sum game. Knowing which players the elite top 1% players are playing is an advantage. Knowing which players appear in the most (or least) lineups is an advantage. This data is only available to insiders (employees of the companies), so that is where the "insider information" analogy is coming from.
