The latest swirl of rumors around the M.C.U. is putting Spiderman in the Ant-Man movie. More specifically there will be references to the world of Spiderman, including but not limited to OsCorp.
Obviously the timelines don't match with Ant-Man filming and final casting has not happened for Spiderman since the departure from Sony.
For now we should take this rumor with the biggest grain of salt we can find.
