I believe the answer to be a resounding “yes”. The DC Extended Universe, started off with Man of Steel in 2013 and will really get going this year with Batman v Superman: Dawn of Justice and Suicide Squad, ahead of Justice League: Part One and a solo Wonder Woman movie in 2017.
Compare this to Marvel Studios’ Marvel Cinematic Universe, which kicked off in 2008 with Iron Man, and a dozen films under its belt, with the entire franchise grossing over 9 billion dollars.

Warner Bros.’ DCEU is still in its infancy, with only 1 film under its belt with rather mixed reviews. But there are a number Suiof factors at play here that could see the DCEU nevertheless end up toppling the MCU, even with it playing catch up.
