If you are going to bet on Valorant online, you'll need to check if the bookmaker is licensed. If you're from the US, you'll have to place your bets with a betting site that operated outside of the US. You can also check their terms to see if US bettors are blacklisted or not. Follow this, and you will be able to bet on Valorant. No specific laws are restricting Valorant betting other than this.
