I also doubt the profitability of the model. I do not know about DFS, but DFS or even gambling in general combined with startup approach (e.g. the horrible attempts of UK bookies like Ladbrokes or Betfred to expand to continental Europe) is I think not very good way to do it.
The chances in the USA were maybe higher when DFS was kind of a legal gambling, but since now situation is changing and DFS is being considered gambling, the attractivity goes down.
But that said does not mean affiliates could not make money there. I have apparently made a mistake here, because there were offered 25-50USD CPA deals, but I went with revenue share. DFS were converting like crazy during NFL season. I am looking at rev share per depositing customer now, I am at 12 USD per customer. I do not think I will ever beat the 50 USD CPA, but I hope this season will make it over the 25. (The 50 USD was only if 100+ players were delivered I think and maybe the small depositing customers were not counted, so it is not that bad).
Either way they will not get as much of my action like last year. I do not trust DK affiliate software, Fanduel is ok. Talked to FD AM, he for sure is a capable person, but they obviously are in deleveraging mode.
IMO - if even such a thing as eSports can exist - DFS can be profitable and nice supplement to gambling but not at the projected scale and pace.
