According to the Wall Street Journal, naming rights are up for grabs to the National Stadium as the 'Bird's Nest' is formally known, along with sponsorship opportunities such as "official technology supplier" and "official soft drink". The next-door aquatic centre, dubbed the Water Cube, is also offering partnership rights, the paper says.
The question of what to do with Olympic venues once all the athletes have returned home is a perennial problem for host cities.
However, with interest in Western-style sports growing in China along with an affluent middle class, the opportunity to have branding on and in the National Stadium is proving attractive.
The US agency acting as a broker on the deal has said that there are six companies competing for the naming rights of the stadium, although they have not been named.
The stadium was at the centre of last week's striking opening ceremony, with fireworks being set off from its roof and former gymnast Li Ning appearing to run the circumference with the help of wires. It will also host the athletics events and the closing ceremony.
Research published by media agency GroupM suggests that advertising growth will continue in China well beyond the Olympic Games, with 2009 spend expected to be up 20% on this year.
