Olympic spending from one Games to the next can vary markedly and be influenced by several factors. For context, every Olympics has two budgets: the Organising Committee for the Olympic Games and the Non-Organising Committee for the Olympic Games budget. The OCOG budget is funded by private organizations and the IOC. This fund is also where proceeds from the sale of Olympic broadcast rights go. The Non-OCOG budget is larger and financed by the host country through public and private funds. It pays for infrastructure, such as the construction of competition venues, and operational expenses like security, food, and medical services.
Every Olympic Games since 1960 has exceeded its budget for various reasons, but delayed construction schedules for megaprojects seem to be the initial domino that sets overrun costs into motion since the Games can't be moved and they operate on fixed deadlines. This was the case for Rio de Janeiro Games (#8 on the list). Even with just 500 days to go before the Olympics, Rio had yet to start on several construction projects. At about the same point in time, the London Games (#7) already had 80% of its venues and infrastructure completed versus only 10% at Rio, according to Reuters. A corruption scandal also delayed private contract payouts.
In addition, the IOC budget only includes operating the Games for 17 days, not expenses that lead up to staging the far-reaching event, according to Andrew Zimbalist, author of three books about the economics of the Olympics. "The number itself is very fungible depending on what you want to include," Zimbalist told The New York Times.
Despite the questionable economics, many cities do proceed, partially buoyed by construction industries motivated to approve an Olympic bid and its commensurate billions in building projects, as well as political agendas for countries wanting enhanced prestige on the world stage.
Though final figures are still years away from being tallied, the 2024 Paris Olympics seems poised to cost less than in years past. The Paris Olympic and Paralympic organizing committee estimates spending $9.7 billion and expects to break even.
