The Money in the Bank ladder match is a professional wrestling ladder match held by WWE. It was first contested in 2005 at WrestleMania 21 and was exclusive to Raw Superstars. Since the match’s inception, five additional Money in the Bank ladder matches have been held annually at their pay-per-view event, WrestleMania, the most recent being held at WrestleMania XXVI, and all subsequent matches have been inter-promotional. In July 2010, a second and third Money in the Bank ladder match was held in the same year at an event also titled Money in the Bank for the Raw and SmackDown brands respectively, breaking from the WrestleMania tradition.
Until the establishment of the Money in the Bank pay-per-view event, wrestlers were allowed to use the contract to claim a match for the world championship of any WWE brand if they desired. Edge and Jack Swagger, who were both Raw wrestlers at the time they had won Money in the Bank contracts (Edge with the contract for which he defeated Mr. Kennedy and Swagger with the contract he won at WrestleMania XXVI), did this on the episodes of SmackDown that immediately followed their contract wins.
