I wonder if it can really be enforced. It's clear that prediction markets are a scourge -- there seems to be no upside whatsoever.

Whenever I see something weird happen in a sports game, or even a lack of effort by individual players, my first thought is if sports betting was responsible.

For the record, Minnesota currently has a complete ban on sports betting. We've seen a couple other states that allow sports betting go after prediction markets. Personally, I feel that any state that allows sports betting is going to struggle to argue a case to ban prediction markets because you're essentially arguing over implementation details. Even arguments that certain prediction markets are ripe for insider tr…

I think sports betting is a lot less harmful than prediction markets. With sports betting if someone throws a game to get a pay day, for instance, the only real consequence is on the reputation of the sport. In prediction markets, people can do all sorts of awful things to make money as insiders..

there is one upside, its a big incentive to indirectly leak things like album release dates and military operations. anything that helps get some secrets out is a positive in my book

No, this doesn't work. Predictions markets can only resolve to things that are publicly verifiable, so any leaked information is information that was destined to become public anyway. Furthermore, the leaker is disincentivized to leak in such a way that the act of leaking could compromise their insider knowlege; the structure of the markets means that leakers don't want you to have this information in any way that op…

Unresolved markets transmit information too. A market doesn't need to resolve to transmit information.

Most available data suggests that sports betting is much worse for the people making the bets, as it better targets people with poor impulse control. Bad bets in political markets aren't causing measurable increases in bankruptcy and domestic violence rates (https://thezvi.substack.com/p/the-online-sports-gambling-exp...).

> there seems to be no upside whatsoever There's the same upside as pretty much all other forms of gambling. Plenty of people enjoy it and it can be used to generate tax revenue for the state. Don't get me wrong, there's tons of harm that can come from it, but the arguments to allow them are essentially the same arguments for allowing sports betting.

This is true, however many of those arguments are weaker when applied to things for which the outcome is more consequential than the outcome of a sporting game.

Sure, but that's not really an argument to ban prediction markets, it's an argument to regulate what the public can or cannot bet on.

Most major online sportsbooks have taken bets on the US presidential election for well over a decade. I can't imagine anyone really arguing that it's okay for DraftKings to offer that market, but not okay for Polymarket to offer it.

I put it somewhere else in this thread, but there are actually two different questions that need to be answered separately. Are prediction markets just sportsbooks by another name and are there certain things that we should not allow people to gamble on.

The argument around prediction markets always seems to squish those two into one which I think does people who want regulation a disservice. I think to most people, the answer to first question (are prediction markets just sportsbooks by another name) is a pretty resounding yes. The second question has a lot more room for debate though. Even if people agree that there should be things we don't allow people to bet on, there's still plenty to argue over where we draw the line. The problem is that as long as we mush these two together, people will use the disagreement over the second question to prevent action from being taken on the first.

Sure, and a white noise generator transmits information too.

Isn't the stock market a prediction market as well?

No, a stock is a share of ownership in a company. Now yes, people bet on the derivative value of those ownership shares... but that also happens to basically every asset. If a stock is a prediction market, then so is corn, and gold, and your home.

Yes, they are. Accurate prediction is rewarded in every market, for every asset or asset class. There are adjacent order benefits (I live in my home, I eat corn, I have a say in how a company is run) but these are never divorced from the impact of prediction and prediction in aggregate is just a crowdsourced leading indicator of value; oil spikes the moment a missile hits Iran not because the 2 are explicitly linked, but because the market has predicted the effect on the flow of that oil over some subsequent timeframe and priced itself accordingly

But I thought the Supreme Court said online sports betting was interstate commerce and out of the domain of state legislation. Or did I get that completely wrong?

No, the SC said the federal government can't outright ban sports betting. The logic was that a ban interferes with states right to legalize sports betting.

(To be clear, it is still an nonsensical decision though. Congress does still have the power to regular gambling under the interstate commerce clause, just not outright ban it)
