Plans to turn the Olympic Stadium into part of a Formula 1 track are among four bids to use the venue after the 2012 Games, reports BBC Sport. West Ham and League OneLeyton Orient are other bidders, together with the UCFB College of Football Business.
It is understood Orient's proposal is based on a ground share with West Ham, although the Premier League club have previously insisted they are not considering that arrangement.
Orient chairman Barry Hearn refused to comment on a possible ground share, but told BBC Sport he was hopeful of success.
"There is no point dwelling on the design of the stadium and the faults of the stadium," he said.
"We have to get on with it, we have to make a fist of it and we have to make sure the Government and the people of this country get maximum value for the investment that has gone into the Olympic Stadium.
"Our idea does that and I think it forms part of a legacy that people in this country can be proud of. Bearing in mind this is the only time in our lifetime that we are ever going to hold the Olympic Games, we need to get something out of it.
"A mixture of usages and a mixture of opportunity within the Olympic Stadium will give us the feeling that we have spent our money wisely and that is really what we are trying to achieve. All sides have to exercise common sense and move forward. I think we have created a very interesting scheme that can do just that."
