Holy shit that felt dystopian. The CEO talking about people betting on whether bombs would fall or not is insane. Like something you’d read in a Sci-Fi novel.

Imo the most dystopian thing is that these betting markets can encourage people to do horrible things. Make a bet on a prediction of something horrible happening -> be the one doing that horrible thing.

yep, basically be the participant insider to win it's less prediction than an assured event

They're also betting on who will win pre-taped reality tv shows. Far less sinister, but it's normalizing bets on events that already happened and just haven't been released publicly yet. With zero insider trading protections.

These sites actually encourage insider gambling, the rationale being that it makes them more "accurate" at prediction.

Someone bet that Trump would praise Allah on Easter Sunday and then made off with his winnings after he did. Insider trading that blatant should be illegal but because its an app that is skirting some laws they get away with it

While insider trading is definitely happening on the site, this story is simply untrue.

Insider trading on geopolitical events is bad enough. Committing geopolitical atrocities for the sole purpose of controlling betting outcomes is short-story-that-you-read-in-high-school-literature-class levels of dystopian.

"Will get assassinated before August 17th? I bet 10000$ on no" *Assassin bets against.* New way of paying for assassinations discovered. PS (I dont have an ex-wife, this is an example of something bad that could happen in theory, not something i am secretly dreaming about).

Wasnt the d**** in WNBA games thing a low key version of that. It was clear the WNBA weren't too keen on it. But people kept doing it (assumably to make money on Polymarket)

PeopleCallMeSimon 4 days ago +3
They mention this in the video as an example. It started as a thing some people did to bring attention to some crypto coin thing, but then it became a thing on polymarket and people started bringing dildos to WNBA games and throwing them on the court to win bets. And more innocent example is the CEO (or something like that) of Coinbase (or some other crypto thing, i cant remember which one) ended an earnings call with investors by saying "I looked at some predictions on Polymarket earlier today so i just want to finish the call by saying "

...Yeah...about that... So about a month ago, a conflict reporter Emanuel Fabian, reported on a missile strike. However because that missile strike was part of a Polymarket $23M wager...the reporter received a massive influx of fury from people, bots and companies because the report could make the bet lose a lot of money. > **[Polymarket gamblers threaten Israeli journalist over missile strike story](https://www.theguardian.com/world/2026/mar/18/polymarket-gamblers-threaten-israeli-journalist-missile-strike-wager)** - *Emanuel Fabian says his routine report became focus of wager with $23m at stake on online prediction platform* - The Guardian - > An Israeli journalist received threatening messages from users of the online prediction platform Polymarket after one of his reports, on a minor missile strike near Jerusalem, suddenly became the focus of an unresolved bet about the Israel-Iran conflict. > > **“After you make us lose $900,000 we will invest no less than that to finish you,” said one message** to the journalist, Emanuel Fabian. > > **Another said: “You have 90 minutes left to update the lie. If you do this, you will solve the most serious problem you have caused yourself in life … If you decide not to correct it, and leave the lie intact, you will discover enemies who will be willing to pay anything to make your life miserable.”** > > ... > > **The messages started soon after Fabian reported** on a missile striking an open area near Jerusalem on 10 March. “It was a relatively unimportant update during the day,” said Fabian, a defence correspondent for the Times of Israel. > > No one was injured in the strike. Fabian wrote a quick blogpost, including dashboard footage of the explosion that someone had sent him, and then moved on to another story. > > **The first email, later that day, asked him to change the story so that it would describe missile fragments hitting the earth after an interception**, as opposed to a missile. > > Fabian, who had checked the details with the military, declined. **“I was very confused as to why anybody would really care.** It doesn’t really matter. At the end of the day, nobody was hurt.” > > **More messages followed, increasingly aggressive. Then Fabian started getting messages on X and realised that the accounts that were writing to him appeared to all be linked to Polymarket users.** > > **He eventually found the specific wager, with more than $23m at stake: whether or not Iran would strike Israel on 10 March. A “strike” had to involve a bomb or a missile, non-intercepted, hitting Israeli soil. The people getting in touch with him stood to win if it was determined that a direct strike had not taken place.** > > “It all balanced on my inconsequential report. **I thought for a second: should I change it and get these people off my back?” Fabian said.** > > **He didn’t. The messages continued. One person wrote to him more than 100 times throughout the night, he said, trying to call him and threatening his family.** So right now if you are a reporter and you report "incorrectly" even in benign terms (the gist of the this bet was the *term* being used) because a Kalshi / Polymarket bet has millions of dollars riding on it, there is now a financial incentive to bully, harass, threaten and even harm said journalist through users, people, bots, emails, physical threats and actual harm. It isn't just that Kalshi and Polymarket incentivize this behavior in the first place, it is that if said betters are successful in bullying a few reporters even to the point of harm (again, there is so much money riding on this now), it only emboldens and escalates more bullying behavior against even more journalists, because there is a strong financial incentive to do so. Given that both companies have a direct line to the White House right now...I shudder to think how much more violent and gruesome efforts to chill speech and journalism would be now that there is an actual *economy* built to enable said chilled speech.

I bet if a lot of new users started placing bets on whether the C-suites' houses would have... let's say dildos thrown at them, it'd be a week or 2 tops before policies changed.

It's not dystopian. Prediction markets are an incredibly useful tool. The problem is that these "prediction markets" aren't really that. They're just casinos. Now, casinos do a pretty good job of predicting as well. However, that's not their purpose. Their purpose is to fleece money from people with low impulse control. The way you actually do a prediction market on whether bombs would fall would be to take a bunch of guys working at the DoD and have them wager primarily on *ego*. You might bet $5 but what you're really hoping to win is the esteem of your colleagues for your correct guess. The "Wisdom of Crowds" actually works. However, the mechanism by which it works is not really information but expertise. If your market includes people who already know the outcome, the market is pointless - you just ask the people who already know and ignore the people who don't. Rather, the process involves recognizing that all those experts have a fraction of the picture necessary to understand the future. By properly weighting and aggregating their opinions, the likely truth reinforces itself while the noise averages out. And, yes, this means you 'bet' on horrible events. Because if you've got a tool that permits you to predict - and potentially mitigate - those horrible events it would be morally reprehensible to not use it because it makes you feel icky.

If you fall seriously ill, some "morally bankrupt" doctor will offer to chop into your body with sharp objects. Are you going to object because of how icky that makes you feel - or are you going to recognize that they're just trying to save your life? Every day a lot of people need to do some things you may be uncomfortable with to protect you from far worse.

I don't think it's wrong for people in the know to bet on something that they know will happen, no. Whether it's bombing, or any other event. If you are dumb enough to gamble on something like that, you deserve to lose your money.

Maybe you just didn't watch the video, but I'm talking about these people winning 100's of thousands of dollars with accounts they are making right before these events happen. I don't know what you think is wrong about people who know what is going to happen taking money from people that don't know what is going to happen. It sounds like you think the decision to bomb a country or something is based on these prediction markets, which is a ludicrous accusation, and quite frankly, I'm only responding because you are hilarious

New, unregulated frontier of not-really-random gambling. Combine this with lenient control on markets, and they basically print money, while the masses are busy with ideological war.

You can bring in a lot more money insider trading in other markets than PMs if you had a direct line to the president fwiw. The polymarket etc markets are nowhere close to as liquid as other markets

I’m going to be honest. I like prediction markets but I think they are so misunderstood by everyone (even John) they get used poorly and we see bad results because of it. Especially for those “fixable events” If you want to bet on whatever will be said during the Coinbase earning call you can but everyone should know that is a an extremely highly fixable event therefore the market cap of that even should be really really low and it most likely was. If people want to “fix” events or bet on something they have influence over they should be able to. People should just be aware to stay away from those types of bets where people can fix it. Imagine a future where people actually openly embraced a prediction markets position as a commitment to do something? Like in the 2028 election the democratic nominee said “Day 1 I will sign an executive order legalizing whatever and I will put 20 million down to prove it” If they do it he “wins” that bet but in reality he mostly will get his money back and money from anyone who doubted him This here is where I think we should logically separate the highly fixable events from the idea we’re predicting and instead measuring one’s “commitment”. Essentially it can be used as a way to judge one’s stake in the proposition. If someone is telling you something the should be willing to put money towards it. It’s a way of monetizing trust in a way.

It’s really lazy to simply hate on the prediction markets when it’s really the lawmakers allowing this too. I dont the coverage is exactly fair because there are obvious upsides to the technology by the transparency over compared to a sports book Maybe in four years we will have some proper legislation trying to tame it but it won’t happen any time soon. I would be happy if they limited the size or number of contracts a single person could have on the position. They could require KYC to buy a contract and trace it that way.

Yes. People are on their high horse because in response to the govt not enforcing insider trading, they're blaming prediction markets as a whole. Similar stuff is happening with AI, hoping calm minds win out in 2028, but not hopeful.
