The yearly revenue from all gambling activities is approximately $1 billion. From this $150 million is generated in tax profits. While the revenue is quite high for a tiny state like Delaware almost nothing is coming from the state-based online casinos. Unfortunately we don’t have any recent numbers, but from 2014 – 2017 the online gambling revenue looked like the following: 2014: $1.4 million 2015: $1.8 million 2016: $2.8 million 2017: $2.4 million In comparison the state run lottery program generates about $450 million a year and the land based casinos in Delaware approximately $550 million.
