The U.S. Attorney's office indicated Friday in a brief court that Madoff is ready to waive an indictment. Such language is used when plea deals are ready to happen.
Madoff is accused of orchestrating one of the biggest financial frauds in history, a scheme that wiped out the life savings of investors around the world.
A message left for Madoff's lawyer was not immediately returned.
Prosecutor's spokeswoman Rebecca Carmichael declined to comment.
