While neither budget has been confirmed, a new report claims that Avengers: Infinity War had a production budget of nearly $300 million, although an exact figure was not divulged.
There was a report from a few years back that claimed the combined production budget of both Avengers: Infinity War and Avengers 4 would be $1 billion, meaning that each movie would cost $500 million apiece.
This report from The Wall Street Journal also reveals that Avengers: Infinity War has already sold more than $50 million in advanced ticket sales, which is currently good for third best all time behind Star Wars: The Last Jedi and Star Wars: The Force Awakens.
There is no indication that Marvel will confirm the production budget for Avengers: Infinity War, with just one week left until the first sneak peek screenings are held on Thursday, April 26.
