Yes, this is precisely how Polymarket works under the hood. IIRC you can even participate by working directly with the smart contracts.

This has always been the case for most high-stakes gambling. The problem isn't winning big, the problem is getting the counterparty to pay. Skilled gamblers (when it comes to games with any skill component) throughout history have been adept at winning subtly and then moving on before anyone figures out they have an edge.

Indeed. I also want to give a recommendation in favour of forecast aggregation platforms like Metaculus and GJOpen. Aggregating forecasts works well even without phrasing it as gambling, because you can still have users compete to be the most accurate.

I think the other side of the argument goes that (a) the bombings would happen anyway, and (b) bombing is very expensive so nobody actually profits from the insider trading. (The bombs "only" get marginally cheaper.) Thus the only actual effect is the early warning, which is a good thing in this case.

Like if someone managed to figure out a way to make slightly cheaper bombs but with the tradeoff that the cheaper bombs gave a few hours of eary warning to the people being bombed, I think I would prefer you used those bombs.

(There are many other cases where insiders may change the outcome to align with their bet. That is bad if the outcome is bad.)


> (b) bombing is very expensive so nobody actually profits from the insider trading

The people profiting aren't buying the bombs with their own money.


>bombing is very expensive so nobody actually profits

You don’t actually believe bombs are sold without out a proper margin.


Capitalism took care of the exchange between money and power long ago. Prediction markets, as terrible as they are, are peanuts in comparison.

yes, because the last century of communism showed that it was really just capitalism where centralized power corrupts..

kqr didn't make that claim

There are no fees on Polymarket. Not sure about others.

> There are no fees on Polymarket

"Currently, small fees apply to Crypto and Sports markets.

Starting March 30, 2026, this will expand to include other categories like Finance, Politics, Economics, Culture, Weather, and Tech" [1].

More critically, Polymarket doesn't pay interest on deposits. (Kalshi does.)

Thanks for the correction! I have to admit it was a while since I last looked into this and I shouldn't have been so confident.

There is a fee implicit in the market spread. It's formed out of the time value of money w.r.t. the cost of NOT trading as well as the adverse selection faced by those with standing offers.

Increased insider trading will increase spreads.


Then explain why the average prediction market has a smaller spread than the average equity option market.


Is shorting a company and then murdering its CEO considered insider trading in your jurisdiction?

That wouldn't be insider trading; in fact unless the CEO's death was known to insiders, it almost by definition couldn't be insider trading.

It could be other types of fraud, however.


> weather prediction markets

Can also be used to hedge the risk of rain on the day you've planned an outdoor barbecue!


You can do this with some forms of trip insurance. I stared hard at arbitrage there a few years ago but it was too hard to get your money out if you were right.

Happens already. Selling market data is part of how they finance themselves.

Sure, and pay our enemies to reveal their secrets to us. That's exactly the point of these things. Dangle money in front of people who know things we want to know.

> pay our enemies to reveal their secrets to us

Something tells me China has better opsec around such leaks than we do.


Taiwan is going to be invaded before 2030

Then go bet on it! Why are you telling us?

To fake out the markets

> You don’t have any enemies. Nobody cares about you. Nobody is coming to hurt you or your family

Do you think the U.S. and Israeli militaries have personal vendettas against each and every civilian we've killed in Iran? Of course we don't. We can barely count them. Just because you aren't personally on your community's adversary's radar doesn't mean they aren't a threat.

(To be clear, I don't believe Iran was a threat. But there are threats to Americans, and it's absolutley not brainwashing to ascribe a threat to a group to oneself personally instead of waiting for it to be purely selfishly relevant before acting.)


The number one most proximate enemy to a regular person is their local/national elite and their sycophants/enablers.

How easy this is to comprehend when Iran is killing protesters.

> Nobody is going to attack the US if your government stopped trying to meddle in other countries affairs

How did that work out for Ukraine? The idea that we live in a just world where everyone who has chaos rain down on them deserves it is so simply refuted even by a cursory glance at just modern history.


I hope you understand that the US is Russia in this metaphor, and you’re the guy jumping off a building hoping to break your legs so you don’t get sent to the frontlines

p.s. No, this is is not because of the account's political views; I haven't tracked them and don't know what they are. We just care about preserving this forum as a place for curious, respectful conversation, whatever one's views.


You’re significantly worse off assuming your government is adversarial than cooperative, regardless of what reality may be, and the majority of us know that. It’s why the chaos psyops aren’t working. We’re not happy with our government but apes together strong

> what has that attitude gotten you?

I've gotten language I wrote passed into multiple state and a few federal laws. Definitey helps when I'm the only one to call my electeds on an issue.

The lazy and nihilistic aren't great for our country. But they're great if you put any work into civic engagement.
