What is Markup in Poker?

In the world of tournament poker staking, markup is a premium charged by a player to investors. For example, if a player is selling a 10 percent share of a $10,000 buy-in tournament, at 1.2 markup, as an investor you would pay $1,200 ($10,000 * 0.10 * 1.2) for a 10 percent share of that player’s potential winnings in the tournament.
