There are 3 separate reasons WHY states are so strongly opposing Kalshi's sports gambling: 1) Kalshi is doing it in a way that avoids state taxation, licensing and regulation, 2) the online sports gambling companies spending billions on TV commercials don't want untaxed, unregulated competition, 3) The major sports leagues are concerned it will undermine the integrity of the 'product'.

Of course, there's no material difference in actual harm to the public between Kalshi sports betting and Online Sportsbook Apps, they both enable gambling addicts, cheating, etc. The hardball reaction is about ensuring Kalshi sends tax, licensing and lobbying money to each state government. The sportsbooks have spent billions ramming gambling legalization through and don't want Kalshi getting a 'free ride' on the bus they paid for.

Even the sports league's opposition isn't as pure as it appears. While they don't want players, coaches or referees to undermine game outcomes, they also sell exclusive access to real-time on-field data feeds to sportsbooks for hundreds of millions of dollars. The TV feeds we watch at home are ~8 to 15 seconds delayed. Getting the real-time outcome data from every pass, kick and run in 800ms vs ~8s on TV is worth hundreds of millions to online sports apps because it lets them front-run real-time bets. When people at home make real-time prop bets on the next play, many times the company already knows the outcome. Something to remember next you hit "Bet" on a real-time prop and get a spinner saying "odds updating" and then "bet expired". It might be because your bet was going to win, while if you'd taken the other side, it would have accepted the bet and taken your money. Yeah, that's against the law in a casino but not in an online sports app. Right now, those apps being "Regulated", mostly means they're paying taxes, licensing fees and following "Know Your Customer" policies to minimize money laundering and minors gambling. Actual fairness of the bets doesn't enter into it any more than carny midway games. Consumer bettor's job is to consistently lose, while only winning a little back often enough to bias selective memory and keep them interested. Anyone who actually wins too often on bets that are too big, quickly gets their acct capped to $1 bets.
