The market
Illinois moved to a graduated tax that climbs to 40% on the largest operators, one of the most aggressive structures in the country. Since a per-wager tax arrived in July 2025, several books have passed the cost on through per-bet fees or higher minimum stakes. The market is still large and busy.
What this means for matched betting
The graduated tax hits the biggest books hardest, and they're usually the ones running the biggest offers. When the largest operators trim back and the smaller books hold steady, the smaller books are where the value is. Ten operators gives you plenty of prices to hedge against.
