However, in recent months, we were able to see the best sports betting sites USA slowly enter the market, especially in the states that were open to sports betting before. In the year that went by since the PASPA was declared unconstitutional and states were able to organise their own forms of legal betting sites in the USA, there was a lot of uncertainty and confusion regarding how the online betting landscape would look like eventually. And while it’s still not clear what caused this big change in approach, every punter and operator out there is delighted that the USA betting sites now have a real chance to thrive after the Supreme Court repealed the PASPA. The Professional and Amateur Sports Protection Act passed back in 1992 banned all forms of sports betting in the USA and made it impossible for online betting sites USA to exist. As previously mentioned, sports betting in the USA wasn’t legal for quite a long time.
