I wonder if this sort of corruption will become a new negotiation tactic. Give us what we want and we'll delay the announcement long enough for you to make preparations. I don't know how Polymarket works, so maybe you can enlighten me: can Polymarket be subpoenaed to provide the recipients of the payouts? Is there some insulation to keep them ignorant of their identity?

Just imagine how bad insider trading is on other markets. Stricter laws and crack downs should be implemented globally.

Given the accused breaking of ceasefire shortly after agreement, not sure how this bet really gets paid out.

There's a saying in poker that if you sit down at the table and can't immediately find the donkey(1), you are the donkey. At some point, anyone playing around in a prediction without insider info will be the donkey. 1: https://en.wikipedia.org/wiki/Glossary_of_poker_terms#donkey

woah

Can someone articulate what the harm of this is?

> as records show substantial bets They're not bets anymore. Now they're swaps.

Is there really that much liquidity in these bets? Polymarket is just a broker right? So people are putting up tens of millions cumulatively on the other side of these random bets?

It can be said that Trump's "tweets" on that day were strategically engineered to first bring this bet to near zero before ultimately bring it to a hundred. In this way, the maximum winnings could be made by someone with insider knowledge.

I've tried to have sympathy for people who lose money gambling but I just can't. Maybe some argument can be made for the fool who loses money on something silly like a sports game, but people certainly not for people trying to make a buck off of death an destruction.

So I follow the oil and gas industry and markets. For anyone that doesn't know, commodity markets mostly operate two different markets: futures and spot. Futures contracts are an agreement to deliver (or take delivery, depending on which side you're on) a certain quantity of a standardized commodity at a given date. Futures markets tend to be a mix of speculators (who are simply betting on price movements of the underlying) and traders who produce or want the underlying. The advantage of a futures contract is it can allow someone to hedge their costs and lock-in prices. All sorts of producers and industries use them for that. Oil futures are standardized into several standard types (9 I think, I might be off). You will hear terms like West Texas crude and Brent. This refers to two main factors: the relative mix between lighter and heavier hydrocarbons (called the API gravity) in the oil as well as the sulfur content. One side benefit of all this is discovery . It's a way of measuring sentiment. So if future oil prices rise, it indicates market sentiment is negative about the war and they further disruption is expected. When it looks like hostilities may end, the price drops. But there's a problem: nobody trusts the market anymore. It's being manipulated as insiders are clearly frontrunning news with massive bets, sometimes minutes before news gets released. This has been happening with other markets too, most notably SPY futures. Markets cease to function once manipulation becomes widespread. The future price is also called the paper price and another signal that the paper price is meaningless is that the spot or physical price for oil has skyrocketed well beyond any oil prices you might see in the news. For example, a few weeks ago, physical Dubai oil was nearing $180 per barrel. West Texas crude had a future price of $110 yet the physical price was $140+. An issue here is that the physical price isn't easily discoverable. It's hidden behind subscription services that cost thousands so you only hear about it when it's reported on. But this means talking heads are reporting on $110 oil when it's really $150. We saw a similar mismatch with the silver market at the end of last year. That market too was clearly being manipulated but rather than insiders, many (including myself) suspect it was the refiners and others who had lost with silver's massive rally and were doing everything to pop the bubble, including changing the exchange's liquidity ratios to force sales. In previous years, some or all of these people would get investigated and prosecuted by the SEC for insider trading. That agency has been defanged by putting a pro-deregulation loyalist in charge but the bigger problem is that some or all of these people will be buying pardons before the president leaves office. And the president can no longer be prosecuted thanks to the Supreme Court inventing presidential immunity. One source of American power is the control over the global financial system. All of this insider trading risks dismantling that. It's not hard to find people who are sitting out because they simply don't trust anything anymore. If this spreads to financial institutions and institutional traders, that's going to be a big problem. So-called "prediction markets" (and crypto) are even less regulated than that. Unless you have insider knowledge or you're betting on something that isn't prone to insider information (and I honestly don't know what that would be), I'd stay away. And these prediction markets are small fry. SPY futures are a significantly larger market. So is oil and gas. And Treasuries is order of magnitudes bigger than either of those. Yet some of those markets can't be trusted and I suspect this is only going to get worse. I don't have any hope that anyone will ever be prosecuted for any of this.

Can someone explain to me how we haven’t regulated the hell out of the clearly illegal sector of betting on shit that can clearly be insider-traded with little to no scrutiny? Leaders? Are you awake at the wheel?
