Why is Boost.Any an application of the Adapter pattern? Who would be the Adaptee? I'm confused. Thanks!

Who claims as much? An adaptor "adapts" the public interface to another. Arguably, Any just removes the interfaces "hiding" it.
Of course a minimum interface is substituted that allows users to recover the "original", underlying interface.
But I wouldn't call that adaptation. For adaptation, I'd expect to have a useful interface indirectly mapped onto another interface implementation.
Oh, and in
the
std::stringobject would be the adaptee. But that's presuming that you agree that it "adapts" the string to an "any" interface
