Is there any data about which Stack Exchange sites have their questions end up in the Hot Network Questions list the most? In particular:

  1. What percentage of hot network questions comes from each site?
    1. What about all-time, this year, this month?
  2. What percentage of questions from each site end up in the list? (It seems that a high percentage of all CodeGolf.SE questions end up here.)
  3. Which site's questions stay on the list the longest?

And so on. Is there any data on these and similar questions?

I've conducted a small experiment with the Hot Network Questions list from 2018-08-04 to the start of Winter Bash (2018-12-12), so about four months' worth of data. (I posted an initial version over a four week period.) I'll try to make a special Winter Bash update when it wraps up at January 2nd.

Stack Exchange itself does not keep any statistics about this, so this is about as good as we can get it. The data has been collected into a PostgreSQL database which can be found here; the database also contains the output of this query to be able to answer your second question (spoiler: your guess about Code Golf is right). The main information is in the snapshots table, which is just the list of 100 Hot Network Questions downloaded every 10 (later 3) minutes.

Note that some external events might cause a spike in a site's popularity; e.g. I remember that during the Falcon Heavy test flight, the number of HNQs from Space Exploration skyrocketed (pun intended).

  1. What percentage of hot questions comes from each site?

During this period, almost 7% of the Hot Network Questions was composed of Worldbuilding, followed by Role-Playing Games with 5.66%. The top 3 is unchanged since the initial report period (about one month).

 # site             %
== ============= ====
 1 worldbuilding 6.99
 2 rpg           5.66
 3 academia      4.73
 4 math          3.77
 5 workplace     3.73
 6 scifi         3.48
 7 puzzling      3.44
 8 codegolf      3.08
 9 tex           2.94
10 travel        2.73
  1. What percentage of questions from each site end up in the list?

You were right, more than 40% of the Programming Puzzles & Code Golf questions become a Hot Network Question. The site is closely followed by Retrocomputing:

 # site                %
== =============== =====
 1  codegolf       41.44
 2  retrocomputing 40.51
 3  puzzling       35.04
 4  rpg            33.84
 5  worldbuilding  30.76
 6  latin          27.78
 7  outdoors       20.98
 8  boardgames     19.29
 9  scifi          19.23
10  bicycles       18.54
  1. Which site's questions stay on the list the longest?

The winner here (in this time period) is Parenting, but I suspect the results here can rather fluctuate between time periods. Their 12 HNQs were 'hot' during on average of just over 4 days.

 # site          avg time (h) # of HNQ 
== ============= ============ ========
 1 parenting            99.50       12
 2 cseducators          71.13        6
 3 ux                   69.98       30
 4 skeptics             67.39       62
 5 interpersonal        64.57      101
 6 security             56.22      137
 7 workplace            52.97      216
 8 politics             48.75      157
