The petition, launched by Adam Khan, has garnered more than 1,300 signatures of its 1,500 goal since its launch four weeks ago.
"How can we go a month without spoilers?" the petition reads. "You can watch the World Cup and watch a movie as well."
The World Cup is fingered as the culprit for the delay, with the major sports event culminating in its live final July 15.
"The worry for film distributors is that audiences will be caught up in the tournament," Charles Gant, film journalist and box office expert for Guardian and Screen International, told Yahoo.
"So it's easier to play safe and not date your film at this time, especially during the group stage, when all the qualifying nations are competing."
The UK's release date is the third-latest opening for the movie, just ahead of Italy's August 14 opening and Japan's August 31 start date.
Ant-Man and the Wasp's month-later UK debut also distances itself from Disney's other major summer release, Pixar's Incredibles 2, which opens June 15 in the US and July 13 in the UK — a release date timed to coincide with the start of the UK's school holidays.
The Disney-Pixar blockbuster-to-be then has three weeks of breathing room in the UK before Ant-Man racks up what will likely be a large box office.
Shifting up Ant-Man's UK release date to align it with its US counterpart would mean Disney cannibalizes its own box office in the UK, as Ant-Man and the Wasp and Incredibles 2 would then open with just one week separating the two instead of the wide berth it has now.
That later date also means Ant-Man steers clear of Universal's Jurassic World: Fallen Kingdom, which debuts there June 6, over two weeks ahead of its June 22 US debut. Its predecessor, 2015's Jurassic World, peaked as the third highest-grossing film of all time and remains the fifth highest-grossing film worldwide.
Earlier this year, Disney shifted the release of crossover epic Avengers: Infinity War forward one week from its original May 4 release date for a mostly-simultaneous worldwide bow April 27.
That move helped contain the film's many major spoilers and saw the blockbuster land the biggest global opening of all time.

@Marvel Please bring Ant-Man and the Wasp forward in the UK, or at the very least, show a special screening for the die-hard fans.— Sam Cheshire (@SamCheshire94) May 28, 2018

@AntMan could you maybe please move the UK release date up to july? I’ve been waiting 3 years for this movie and I don’t think it’s fair we have to wait an extra month before we can see it thank you— sarah wants justice for amatw (@1940sbvcky) May 28, 2018
Please bring the date forward for the UK, America is such a big audience that spoilers (especially for a whole fricking month)are going to be rampant online and ruin it for us who have to wait. ?— charanjeet billen (@Charlen_92) May 28, 2018
Please can you move the UK release date up? A month is too long to be unspoiled and already seen people say they aren't going to bother seeing it at the cinema because a cam copy will be out :-/— Lula Madison (@LulaMadison) May 28, 2018
Oh yes because August is definitely in 50 day- wait... it comes out a month in July everywhere but the uk? pic.twitter.com/3gzNRPZFlU— cam (@FalconFinn) May 16, 2018
