PARIS — French taxpayers footed a nearly €6 billion bill to host the 2024 Paris Olympics, the country’s highest audit authority said in a report published Monday.

France’s Court of Auditors found state and local authorities spent €2.77 billion to help organize the Games and an additional €3.19 billion on infrastructure. The French government had initially promised that public funding for the Games would cost around €1 billion.

Tony Estanguet, the president of the 2024 Paris Organizing Committee, disputed the auditors’ figures in a response included in their report and said the true public cost attributable to the event “does not exceed €2 billion.” He also noted that the projected economic benefits linked to the Olympics are “three to five times that amount.”

Both Estanguet and Prime Minister François Bayrou, whose response was also included in the report, stressed that the Court of Auditors had failed to adequately quantify the long-term benefits of the Games, including the infrastructure investments that will benefit Parisians long after the Olympics finished, and focused solely on tallying up expenditures.

For example, the French government spent an additional €214 million to extend the Paris metro network to make Olympic sites accessible via public transport by the time the Games began.

The president of the Court of Auditors projected before the Olympics began that they would cost €3 to €5 billion. The report notes that the Games’ organizing committee was “largely self-funded,” but that public funds were used to ensure the event’s success.

Securing the Games ended up being particularly expensive. France spent some €665 million to deploy 35,000 police and gendarmes each day near the various events
