I doubt any of the characters know Batman is a millionaire. That would imply that he's revealed his identity to the Titans and I'm certain he wouldn't do that. I'm not even sure if he's entrusted his identity to the other Leaguers yet either (usually Batman is the League member who least trusts the others... Superman being the only exception).

Well depending on how much gadgetry the dark knight's flaunted so far in this continuity, it might be pretty obvious considering the guy has custom planes, cars and high tech gadgets. That being said that also works against itself because he might still be using some more simpler and secretive then maybe no one would know he's got the bills to pay the bills.
