User blog comment:Jacknapier10/Which characters cannot appear in the Marvel Cinematic Universe?/@comment-5350299-20140428113836/@comment-3317214-20140502170641

No, although the Kingpin has been a fairly major villain for Spider-Man, his film rights are tied to Daredevil, which puts him at Marvel Studios. Not at Sony. He's definitely not one of the shared characters (there are very few of these, apparently). But, those are film rights - any video game appearance is to do with game rights, I'm assuming, which I know little about.
