Pretty sure kagi is a bing wrapper too, although they blend in some other datasets.
Kagi's main results come from Google actually. (edit: see https://help.kagi.com/kagi/why-kagi/kagi-vs-google.html - Kagi really shows how good Google could be, since it's mostly using the Google index and then doing user-friendly things instead of user-unfriendly things on top)

So I wonder what the actual results mix is. Like I said, could be mainly from Google.
