In Singapore, Olympic gold medallists receive SGD $1 million (USD$820k), silver medallists get SGD $500k (USD $410k) and bronze medallists earn SGD $250k (USD $205k). Singapore still has not won a single gold medal yet though. It is quite pathetic really. We actually recruit foreign talent ( from China ) to help us win medals in the Olympics...which is quite pointless really. They are not even bred in Singapore. The money could have been put to much better use.
Anyway, I think the money-earner for these Olympians are sponsorships and endorsements. People like Usain Bolt, he earns an estimated $20 million per year. Michael Phelps is probably worth around $40 million. However, these are the elite of the elites. If you win a bronze medal, you probably won't get many sponsorship deals at all, if there is even any.
