Gary Illyes, the man at Google to blame for the HTTPS ranking algorithm, announced that of the top ten verified sites within the Google Search Console, all ten of them run over HTTPS.
Gary said the top ten was counted by search impressions, meaning, these sites get the most amount of views and probably have excellent rankings, in Google.
I assume Wikipedia is in there but what would you guess the other nine were?
Here is Gary's post on Google+ with this announcement:
Does this mean you should go HTTPS? I.e. you go HTTPs you get great rankings? Absolutely not. But it doesn't necessarily hurt from my tests.
