the one billion dollar budget? Not sure if this is what you mean, but regarding the "one billion dollar" rumor - the cost of the entire 2024 Olympic Games is 4.5 billion... and that's with all the stadium reconstructions, all the construction work going on in Paris, accommodation for everyone etc.
The Burj Khalifa cost 1.5 billion to build.
Fans are throwing crazy numbers around. The entire tour will earn about $200 million, the show in Rio won't cost more than a few millions.
