The report is the result of the visits of the 12-member commission to Madrid, London, New York, Paris and Moscow, in February and March.
It is expected to put London up alongside favourites Paris. Whilst London still needs to build new stadia, it is hoping it will have impressed the IOC with plans to regenerate an area of the city through the construction of an Olympic Park.
Paris meanwhile has much of the infrastructure already in place and is bidding for a third time.
In a large-scale attempt to demonstrate the strength of the French bid, the city organised events for the FC*tons l’Amour Des Jeux – ‘let’s celebrate the love of the Games’.
Most of the Champs Elysees was turned into an Olympic Park with an athletic track at the foot of the Arc de Triomphe and temporary stands displaying an array of Olympic sports. Nearly one million people attended the event.
Paris has also used the French Open tennis tournament to publicise its bid, with the Philippe-Chatrier court (central court) and other key areas decorated with the Paris 2012 logo and motto 'L'Amour des Jeux' (for the love of the Games).
Madrid held a street party on Sunday along its main thoroughfare, the Castellana Boulevard, with a 16-sport festival around the Plaza de Cibeles.
New York, however, says it believes the report "will conclude that New York’s bid is just as strong technically as Paris or London”, despite a further delay on Friday to a vote in favour of its stadium.
Whilst Moscow is the outsider, experts agree that all five cities are well capable of hosting the Games.
