They've moved it a few times so its tough to remember.
Yeah, you're right that Captain Marvel was originally set to be released on July 6, 2018. But then when they made the deal with Sony for Spider-Man, they gave it Thor: Ragnorok's date in July 2017, and bumped everything else back. So Thor moved to November, which bumped Black Panther to July 2018, which bumped Captain Marvel to November, which bumped Inhumans to July 2019.
Currently its:
May 6, 2016 - Captain America: Civil War
Nov 4, 2016 - Doctor Strange
May 5, 2017 - Guardians of the Galaxy Vol 2
July 28, 2017 - Spider-Man (I'm kind of hoping they go with the title 'Friendly Neighborhood Spider-Man')
Nov 3, 2017 - Thor: Ragnorok
Feb 16, 2018 - Black Panther
May 4, 2018 - Avengers: Infinity War Part 1
July 6, 2018 - Ant-Man and the Wasp
Mar 8, 2019 - Captain Marvel
May 3, 2019 - Avengers: Infinity War Part 2
July 12, 2019 - Inhumans
May 1, 2020 - ???
July 10, 2020 - ???
Nov 6, 2020 - ???
May, 2017 - July, 2018 we're going to get 6 movies with only 2-3 months in between each. Wow.
