The board of the London Legacy Development Corporation met on Monday but was informed that negotiations with West Ham had yet to reach a definitive conclusion.
The Guardian revealed last week that a conclusion to the long-running saga was likely to be delayed again amid ongoing discussions over how costs of up to £160m to convert the stadium into a permanent venue with retractable seats should be met.
West Ham remain convinced they offer the only financially viable solution and that their offer to rent the stadium will pay off twice over the length of the tenancy.
Their co-owner David Gold tweeted: "Sadly the decision on the Olympic Stadium has been postponed. We must be patient but resolute."
But the LLDC wants to ensure that West Ham make a meaningful contribution to the conversion costs and is also adamant the stadium could pay for itself without football if necessary. The next fortnight is believed to be crucial, with both sides keen to reach a definitive conclusion, although the LLDC chief executive, Dennis Hone, has said it could take a couple of months.
Leyton Orient, an ambitious but unlikely scheme to host Formula One races in the Olympic Park and a football business college are the other bidders for the £468m stadium, which will have 60,000 capacity in its post-Games configuration.
UK Athletics is guaranteed use of the stadium for 20 days a year and it will also play host to pop concerts, community days and other sporting events programmed by an events organiser who will also liaise with the main tenants.
