As of my last update in early 2023, online sports betting is legal in Illinois. The state passed legislation in 2019 that allowed for the regulation of sports betting, both in-person and online. This means that residents and visitors over the age of 21 can bet on sports through licensed operators.

However, it’s important to note that online casino gambling and online poker are not legal in Illinois as of the same time period. The law specifically addresses sports betting, and any other forms of online gambling would not be permitted under state law.

When engaging in online sports betting in Illinois, you should:

1. Ensure that you are using a platform that is licensed by the Illinois Gaming Board.

2. Be over the age of 21.

3. Be physically located within the state borders when placing a bet, as geolocation services are used to verify this.

The landscape of gambling laws can change, so it’s always a good idea to check the latest information from the Illinois Gaming Board or a trusted legal source before participating in online betting.
