Ecclestone, 83, has told the Handelsblatt and Wirtschaftswoche publications that a decision on the track's ownership could be made soon.
He said: "We have made an offer and now we wait to learn whether it will be accepted.
"We believe that we can do more for the race track than anyone else.
"An agreement could be reached as soon as the next few weeks."
He added: "We want to make sure there is a Formula One race in Germany every year in the future.
"There are one or two other interested parties. But we will only pay what we believe the Nurburgring is worth."
