4. MONEY IN THE BANK
In the past few years, this type of match has gotten extremely popular. In fact, it's gained so much popularity that it's got its own pay-per-view named after it. The general concept behind this particular match is to have a briefcase suspended in the air, above the center of the ring.
Inside the briefcase is a contract, good for one calendar year. With this contract, the possessor can cash it in at anytime, anywhere, redeemable for a title shot against the champion at that time. In the M.I.T.B match, there are usually 6 or 7 participants involved in the match.
Statistics have shown that the winner of the Money In The Bank contract have about an 80% chance of becoming champion, once they decide to cash it in. The most common theme in recent years has been to wait until the current title holder is worn down from a previous match and then make the run-in to capitalize on the champs’ predicament.
One of the more notable cash-ins in recent years, was at Wrestlemania 31 when Seth Rollins cashed in and won the WWE Championship at the end of the event. Most recently, Dean Ambrose cashed in the briefcase the night he won on Seth Rollins to become the WWE World Champion at the MITB pay-per-view this year.
