History

Historical Context

The 2018 Supreme Court ruling in Murphy v. NCAA struck down the Professional and Amateur Sports Protection Act, legalizing sports betting nationwide. Within two years, Nevada’s Gaming Control Board reported a $1.5 billion betting handle, while New Jersey’s lottery generated $300 million in tax revenue. Today, LeBron James’s $8 million Polymarket partnership and Kalshi’s legal battles echo that post-2018 surge, as major leagues and states vie for market share. The precedent suggests courts will continue shaping betting regulation, prompting companies like Polymarket to seek aggressive growth strategies and political lobbying.
