#4 - The first Money In The Bank cash-in on The Grandest Stage of Them All at WrestleMania 31 (2015)
The Money In The Bank concept debuted at WrestleMania 21 in 2005, but never before would a cash-in attempt happen at WrestleMania, until 2015. Seth Rollins was the 15th person to ever win the Money In The Bank Ladder Match when he did so at the pay per view of the same name in 2014.
Brock Lesnar and Roman Reigns were in the main event for the WWE championship. Lesnar just hit his third F5 on Reigns after Reigns hit a couple of spears on Lesnar. With both men down, Rollins' music hit and he sprinted down the ramp to a thunderous ovation.
Rollins tossed Reigns out of the ring and hit a Curb Stomp on Lesnar. Rollins would go for another one, but Lesnar caught him; however, Rollins broke free and Reigns hit Lesnar with a spear. Rollins would hit a Curb Stomp on Reigns for the victory in one of the most thrilling endings to a final WrestleMania match.
