Earlier quoted context omitted.
Artists do not get most of the money from Ticketmaster fees.
Yes, most go to the venue, which the artist/producer would have had to pay for (from the ticket price) otherwise. Because money is fungible it doesn't really matter if they pay the artist, or if they pay for the artist's expenses. What matters is how much fees they charge and how much do they keep. Can't find it right now, but I remember an article claiming they rarely keep 50% of their fees.
The "face value" (base price) will usually be determined between the artist and promoter, the venue will apply a fairly generic fee on top, as will the ticketing provider.
How much of the face value goes to the artist will depend on their leverage in the contract with their promoter. This is usually best improved by the confidence that the venue will sell out, meaning artists with bigger audience and social media presence will usually get the best terms.
I don't have a paper or article I can link to as a source, but I have experience in the industry.
