I think gambling is defined by the players' behaviour more than the game's structure. There are professional poker players who I would argue do not gamble. They're playing risks as much as an insurance adjuster.
On the other hand, someone investing their life savings into McDonald's meals in an attempt to win a sweepstakes isn't buying burgers.
So the question really is, how many Kalshi and Polymarket users display signs of problem gambling? From what I'm seeing, it isn't negligible [1].

Gambling has to do with putting money in a proposition, not with sports. "I bet you I can drink two points before you" is not a financial statement.
In reality, every thing we do in life is a gamble. Even investing in US Treasury Bonds. (And if you don't think so, look at the national debt again.)
I said 'commerce' not 'finance' because finance is just one of many, many things that is within the purview of federal law due the commerce clause.
Imagine there’s a law saying that regulating abortion is federal responsibility and the senate then uses this law as justification to ban demonstrations around abortion clinics. Would that mean that demonstrating next to an abortion clinic counts as abortion?
That's why subsequent courts walked it back. It was an obviously flawed ruling that produces preposterous results.
I mean, can the government prohibit dying (and throw your corpse in jail) because death means buying less food from others? Can the federal government throw you in jail for not having enough children because that reduces the amount spent on baby clothes?
