The Horsemen explaining at the show in New Orleans that the money being added to their accounts is for the losses they suffered during Hurricane Katrina.
To elaborate on that: the man paying for the show, Arthur Tressler, had his company cheat Katrina victims out of their settlements. So the Four Horsemen took the money they were owed out of his account and gave it to the audience. You could hear the sheer glee in these people's voices- they were probably struggling to survive, to live day-to-day, and then, magically- here was hope. Here was something to live on, to build on, and what they were cheated out of. This was one of the pinnacle moments of the movie.
