Put the same energy into championing regulation then. Don't walk away from a mess you claim to have helped create. (which the OP may indeed be doing, but it isn't clear they are, hence the chiding)
avaer•42m ago
The people regulating this are the people profiting from it. Championing change isn't too different from prostrating in front of the King.

Your advice might work in a different world.

People always assume that others will use something with good intentions, but in practice, malice tends to take root before goodwill does.
avaer•40m ago
Not so much malice as greed and lack of empathy.
jameskilton•39m ago
And some things always are malicious, like "prediction markets", which is just gambling reworded to sound like something else.

This was never, ever going to end well. There is no good use of "prediction markets".

fwipsy•27m ago
Some people gamble by trading stocks. Should we also abolish the stock market?

Prediction markets are meant to be the stock market but for events besides the value of a certain corporation. They were co-opted as a thin veneer of legitimacy over deregulated sports gambling. The concept itself theoretically has some value, however insignificant compared to the damage caused by the current policy.

im3w1l•18m ago
Restricting retail trading of derivatives and short positions doesn't sound like the worst idea.
tgma•18m ago
The uniquely problematic aspect of prediction markets is not really the gambling one. There are plenty of speculative vehicles. The problem is it subverts natural incentive structures that society has evolved to reward, by introducing another incentive signal; one that sometimes can be many times bigger, thereby manipulating the natural, real-world, outcomes.

If you were playing in the World Cup in the lesser teams, very often betting+sabotage/plausible negligence would have been a more profitable enterprise for you than to actually do your best to win.

Stock markets have this problem too, but they are much more regulated, and even if manipulated by insiders, the blast radius is smaller and often auditable.

The author was instrumental in a colleague ruining their life through a gambling addiction. Then they helped make the case for prediction markets, which also went wrong.

Their track record is not great, and I don't think they fully realise that the issue is them: the principles and axioms they rely on don't lead to good results.

> I don’t claim to know the exact right policy answer for America.

Perhaps start by reversing your positions, and throwing support behind those trying to undo the damage you caused.

Retr0id•44m ago
Finally a solution to being wrong - just invert all your opinions!
Planktonne•39m ago
If you're consistently wrong, then it's time to stop being a thought leader, and really examine the lens through which you view the world.

The author still thinks they were "freeing prediction markets from unnecessary restrictions", but clearly some restrictions are necessary, and totally free markets aren't actually an economic panacea. This is not really new information, so the flaw is in the thinker, not the data.

If your ideas are consistently proved harmful, acting against your instincts is a better play than continuing to trust them.

fwipsy•32m ago
You're mischaracterizing. He said that he helped build a case for it -- not that he still supports it.

As far as I can tell, prediction markets went from totally illegal to basically unregulated. Presumably the author was arguing for a middle ground.

> And I know exactly what that costs: Before I was an economist, I was a teenager working for bookies on Australian racetracks. I once took five dollars from a coworker who “didn’t bet” and put it on number one in the next race. Six months later he was betting thousands a race and stealing from his own family. Compulsive gambling destroys lives — and the families it wrecks have no lobbyists.

> I don’t claim to know the exact right policy answer for America. But I know we never even had a grown-up debate.

If you've seen the destruction caused by something and can't figure it out, maybe you have a problem?

And let's be honest: the idea of "debating" things that are obvious is often one of the primary ways by which indefensible things are legitimized.

>Trump Media may soon sell early access to the president’s Truth Social posts. Think about what this means. This is how the president announces war; every embassy on earth has to maintain a Truth Social account just to stay informed of American policy.

He is already so beyond the pale this doesnt even move the needle.

beloch•9m ago
If they try this, multiple random people will write bots to republish everything instantly. The cash gusher they expected will turn into a trickle and the white house will look like a bunch of greedy Ferengi that lack the lobes to pull off a basic swindle. It's guaranteed to be an instant loss. I'll laugh pretty hard if they go ahead with it.
avaer•31m ago
> Trump Media may soon sell early access to the president’s Truth Social posts.

Think about whether the spirit of the domestic/foreign emoluments clause would be okay with this. I'm sure some will argue there's enough layers of BS in this scheme that it's totally fine.

Ethics and judgement aside, I think startup founders can learn a lot from this administration as to how "successful" people twist things in their favor. The industry is full of it.

fwipsy•20m ago
I'll admit that I still see some value in prediction markets in theory, but in practice the way they were implemented seems to have caused an order of magnitude more harm.

In retrospect their misuse as a loophole for sports gambling was an obvious outcome. Seems like every promising new technology inevitably is used for evil. Cryptocurrency is mostly used for criminals. Social media displaced more meaningful forms of connection. We're already starting to see this with AI (psychosis, slop, assisting bad actors) but I'm afraid it will get much worse.

Planktonne•17m ago
> In retrospect their misuse as a loophole for sports gambling was an obvious outcome.

This isn't a 'benefit of hindsight' thing; a lot of people called this out in advance, just like all the other tech you listed.

We need to stop listening to the people who are wrong about everything, rather than pretending the maximalist seeking of profit with no regulation is a reasonable position. We know it doesn't work.

rekabis•7m ago
The only true winners in those prediction markets are the insider whales that already know what will happen.

Anyone who is not an insider is a loser.

jongjong•6m ago
My position is that prediction markets are bad and harmful but so are all mainstream stock markets. They're all prediction markets. People collaborate to pump up the value of specific assets or contracts, leading to undesirable outcomes.

It would be dishonest to ban prediction markets without banning stock markets.

The best which can be done, under the current system, is to punish unfair information asymmetries, which is practically impossible to do reliably... And even if we could find a way to punish it reliably; what would happen is that most rich people would end up in jail. Information asymmetry is almost never fair and it's how people make big money these days.

I think the best solution is to create conditions to allow people to earn big money in other ways; ways which create value. If there were other ways to make big money besides unfair information asymmetry, then skilled people would find it easier to do that instead...

Unfortunately, skill/talent does not allow you to gain an information advantage; only social connections do. So the current system is really bad in terms of wasting specialized skills/talents.

mind-blight•4m ago
I don't like prediction markets, but I think a lot of people in this thread are assuming that gambling vs. not is clear cut.

Insurance was illegal at different times in history because it was considered gambling. Ditto for commodity trading.

Even you look at the structure of a futures contact, the basics look really similar to a bet that can be traded with someone else.

The main differences are the regulatory environment, and the intention the actors in the market have.

Commodities, options, and futures are all legitimately used to hedge against future outcomes. The "gamble" (placing money on a future outcome) is a mechanism for the main goal: protection against instability.

When you look at stocks and - in particular - derivatives, it starts to look a lot closer to how gambling is structured. I'm pro stock market, but that doesn't mean I won't admit that the line between it and gambling is pretty hard to draw. It's a lot more grey than people give credit for

You're just describing the preexisting problems that led to bans and regulations on sports gambling.
The author wrote their article--they had the chance to clarify their position. The facts remain: on multiple occasions, they have been instrumental in negative outcomes because of their support for things that we already knew were a bad idea. They should stop giving advice.
fwipsy•8m ago
Fair point.
fwipsy•35m ago
Did you watch the podcast? I didn't, but I think it's unfair to judge the author's true position on prediction markets based only on the hook.

The current admin has bungled better ideas than prediction markets.

indoorfish•19m ago
Gambling isn't some brilliant new idea, even if you rename it. I understand the technical distinction trying to be made, but seriously, it's gambling.

No one "bungled" anything. They just aren't being prosecuted..yet.

fwipsy•17m ago
Sometimes gambling has some social value then. Isn't trading on the stock market gambling? Do you also support abolishing the stock market? What about issuing loans to someone with poor credit?
crooked-v•12m ago
Day trading is gambling. Buy-and-hold is investing. Algorithmic micro-trading is investing, despite looking like gambling. It's about whether there's an immediate dopamine release or not.
fwipsy•9m ago
Properly regulated, couldn't the same distinction be applied to prediction markets?
Planktonne•4m ago
Except the author argued against regulation for prediction markets.

I don’t think we should hold a transaction worth $5 someone did as a teenager over their head as a dark mark on their character for the rest of their life

I would agree, except the author has continued behaviour in that pattern over a larger scale for years after that.
