A new study from the University of Oxford looked at the finances of cities that have hosted the Olympic games and the results weren’t pretty. They found that for the last 80 years, cities have gone over their estimated budget by an average of 172 percent.
As reported by the LA Times, the organizers of L.A.’s 2028 Olympics have said their $6.9 million budget and the sales of tickets and other revenue streams will cover the total cost of the event. And L.A. does have some advantages that other cities don’t, such as a wide variety of existing stadiums. But there are also lots of unforeseen circumstances that could up the cost of hosting such a large production, from natural disasters to security concerns.
