I revised my analysis of the impact that the proposed 1% on bets would have on sports book operators: Impact of a 1% Tax on Sports Betting to include the actual official numbers filed by Nevada’s licensed sports books. I used these to calculate the impact of the 1% fee on a hypothetical book in Indiana. But the figures also allowed me to calculate some interesting numbers for the sports book currently operating in Nevada, which I do not believe I have ever seen published before:

The most recent official figures show that for the 12 months ending in November 2017 there were 195 sports books in Nevada. They won a total of $233,299,000. Dividing the total win of approximately $233 million by the number of sports books, 195, means the average Nevada book wins about $1.2 million a year.

The reported win percentage was 4.82%, higher than the 4.16% hold I used in my impact report. But this includes an increase in parlay cards and parimutuel bets, where the house keeps a much larger share. Still, using the reported hold of 4.82% means the average sports book in Nevada accepts almost $25 million a year in bets ($1.2 million divided by 4.82%).
