I was interested in this, so perusing I found https://govinfo.library.unt.edu/ngisc/reports/2.pdf https://govinfo.library.unt.edu/ngisc/reports/2.pdf which estimates in the late 90s "Estimates of the scope of illegal sports betting in the United States range anywhere from $80 billion to $380 billion annually, making sports betting the most widespread and popular form of gambling in America." which seems surprising even at the low end. similarly from https://www.americangaming.org/new-aga-report-shows-americans-gamble-more-than-half-a-trillion-dollars-illegally-each-year/ https://www.americangaming.org/new-aga-report-shows-american... in 2022 "AGA’s report estimates that Americans wager $63.8 billion with illegal bookies and offshore sites at a cost of $3.8 billion in gaming revenue and $700 million in state taxes. With Americans projected to place $100 billion in legal sports bets this year, these findings imply that illegal sportsbook operators are capturing nearly 40 percent of the U.S. sports betting market." I think what would be more interesting to me is estimates on the unique number of citizens betting. Is it up? If so, how appreciably?
