Gambling is flourishing not because we're in a low-trust world, as the article says, but because the living conditions of an increasingly large part of the population as such that they cannot hope of ever achieving a comfortable life. We're returning to the social dynamics that dominated much of history (if you consider how much gambling was a scourge, from ancient Rome to thousands of years of history in China).

So do you have a lot of trust in people that "cannot hope of ever achieving a comfortable life"? It seems like a risky proposition.

The entire country seems built on taking advantage of people, from my vantage point right now. Whether it’s attention, drugs, or business/legal leverage, everyone is out for advantage and they’re not even pretending to care about people they affect.

> By the late 1970s and 1980s the balance had shifted to where more households than not had both parents working. This is caused by the government sucking up ever larger portions of the economy, while also constricting it with ever more onerous regulations. It has to be paid for somehow.

The enormous increases in government spending is not propaganda.

I think they're saying you bet $1 billion it will not be gone, and someone takes that bet and kills Polymarket (How?)

Ah yes, of course and then he pays poly market ceo half that to close the company in time. But how do you not get screwed in your subterfuge?

> how do you not get screwed in your subterfuge?

You have to make another market that is a proxy for you (not) getting screwed.

Prediction markets advertise insider trading as a feature, and enforcement of financial crimes is a racket anyway. If you know the right people, make the right campaign contributions, laws just don't apply to you.

this kind of cynicism is malignant

but you don't deny there's some element of truth to it tho?

Are the referenced companies referring to their volume as revenue?

There is a class of prediction markets that are useful and seem immune to most of these problems : play money prediction markets. I've been enjoying them for years; I feel they provide a useful service to understand what is going on in the world, and they don't seem to provide the perverse incentives that we are seeing here. Oh, and they seem to work just as well.

Agreed, as long as it's a catastrophe that the bettors can't cause, but for which advance warning can mitigate harms. For instance, I'm in favor of bets that a certain astroid will strike the earth at a certain time and place. A signal from the prediction markets might cause somebody to evacuate in a scenario where they'd otherwise cry "fake news." Let's not bet on whether the water will remain drinkable, because the…

A signal from the prediction markets might cause somebody to evacuate in a scenario where they'd otherwise cry "fake news." I understand the point you're making, but in this case, you're still incentivizing someone somewhere to not attempt to the best of their ability to intervene in that astroid. Bets that…

If the bet can't cause any change in behavior then the whole thing is useless. The whole point is to do some good with it. The constraint is that the bettor can't alter the outcome.

Another one would be discovering malware in a PR and betting loudly enough that it won't get merged. The bet is how you make your certainty rise above the bot noise and attract extra attention on the maintainers' part.

Granted that's also theoretical, but it's worth theorising about how we'll get things done in a world where the only way to be heard is to put your money where your mouth is.
