Empire and Slashfilmhave reported that The Amazing Spider-Man 2 will feature a scene from X-Men: Days of Future Past after the credits. The post credits scene is a staple in comic book movies and usually shows a teaser for a sequel or a tie-in with separate movies. However, it appears that this is just some smart marketing considering both Spider-Man and X-Men are Stan Lee creations for Marvel Comics.
Empire describes what can be expected after the credits:

The Amazing Spider-Man 2 hits theaters May 2.
