Voters should care because prediction markets are becoming a popular way for the public and the media to gauge the likelihood of major events, like presidential elections. If these markets are easily manipulated by wealthy actors or people with inside information, they provide a false sense of what the public actually believes and can potentially sway public opinion or financial markets unfairly.

Currently, there is some legal debate over exactly how much power the government has to regulate these markets. If this bill becomes law, it removes that doubt and creates a more level playing field for anyone using these sites. Without it, prediction markets could become a 'wild west' where the person with the most secret information or the biggest bank account can cheat others without facing federal consequences.
