Illinois has no law written specifically about digital rips, and rip apps currently operate there under their own terms.
Illinois has one of the highest sports betting tax regimes in the country, which pushes sportsbooks to look for other revenue. That makes Illinois a likely early market when sportsbooks launch rips products.
