Why is polymarket any more or less dangerous than NFTs or naked option trading? Fool and his money are quickly separated…

To be fair, when you place bets on Polymarket, your losses are limited to the money you put up.

But if you write uncovered options, your losses are theoretically unlimited.

Agreed, though. It's bizarre that this isn't regulated exactly like gambling. Because... that's what it is.

What's the point of posting entire book fragments here?

So that lazy people who form their worldview via a Quick Google Search, Wikipedia articles, and/or "news media" can actually have a chance to learn something real about the time they are living in. It's like a dozen paragraphs, forming one complete argument. Is this too much material to take in all at once, in this brave new TLDR tomorrow?

The powers that be have always saught wealth. At some point they gained enough power to start usurping the law that was supposed to keep them in check.

We should have made it clearer that monied interests have a choice: be kept in check by the law, or by the guillotine.

I'm too entralled by TikTok to build a guillotine.

What is the legality for US residents? Right now Polymarket is subject to a federal agreement that they don't let US people participate. Apparently this is just a checkbox for the user to attest to. They don't even do IP geolocation, never mind payment checks. So it's currently illegal for them to run this in the US. But is it illegal for users to participate?

They do check geolocation on order submit. You can read the site from anywhere, though.

Ah, I did not get that far in the enrollment process. Thanks!

> Right now Polymarket is subject to a federal agreement that they don't let US people participate. This changed last month.

What changed?

"The mercantile classes at first thought themselves exempt from the general misfortune. They were delighted at the apparent advance in the value of the goods upon their shelves. But they soon found that, as they increased prices to cover the inflation of currency and the risk from fluctuation and uncertainty, purchases became less in amount and payments less sure; a feeling of insecurity spread throughout the country…

Please don't make posts consisting of quotes and nothing else. HN is a supposed to be a site for curious conversation. It's not hard to see how posts like this interrupt that and bog it down - imagine someone at a dinner party* reading entire paragraphs like this out loud. (* I don't know why I said "dinner party", since I don't go to those, the conversation usually isn't good, and they aren't my idea of fun, but oh…

It definitely bogs things down. I would have preferred even an AI summary of the text, granted that it was accompanied by additional commentary to tie that to the subject at hand, rather than dumping in text with the assumption that the reader will understand the implicit connection.

Prediction markets have an alluring quality that they become a pulse-check on what humanity believes is going to happen, putting your money where your mouth is, and when they work like this they work pretty well and are an interesting instrument. Brian Armstrong, the CEO of Coinbase, has even gone so far as to say that Insider Trading is a necessary source of data for prediction markets, if the goal of prediction markets is to be an accurate prediction of the future [1]. However, it seems increasingly clear that even this function of prediction markets doesn't behave how the silicon valley elite seem to think it does. In multiple markets throughout 2025, we saw insiders "snipe" correct predictions at the last minute, while odds were still against the correct outcome, moments before some finalizing event or news became public.

In theory, insiders give correct signal. But in practice, their volume is often too low to meaningfully move the market in the correct direction, and the timing of their order flow can be too late for that signal to actually be useful as a tool for predicting the future.

Its also critical to note that insider trading laws don't just exist to protect investors. They exist to protect the organizations the insiders belong to. The order flow on both prediction markets and the stock market is public information. Its one thing to short the company you work at because you know they're going to announce bad earnings. Its another thing entirely to take out a million-dollar position on "US Strikes Venezuela before Jan 3: Yes" on January 2nd. Sophisticated geopolitical opponents are monitoring these order flow feeds, and it begins to become a genuine matter of national security.

Overall, I am fine with prediction markets. I think they're an improvement over sports betting in the sense that they better-align incentives between the participants and the market-maker. In typical sports betting, the casinos running them set the odds, and participants take out positions against the casino; which means the casinos are incentivized against allowing anyone to actually make money on their platforms. This has surfaced many times in "professional sports betters" getting blacklisted. In comparison, PMs are a contract between participants, and the market-maker only takes a fee on each transaction (Robinhood's is 2.5%; quite high), which means the market-maker is only incentivized to increase PM order book volume and provide interesting markets. There's more opportunity for actual skill and dedication to shine through.

But, KYC is critical.

> The irony of prediction markets is that they are supposed to be a more trustworthy way of gleaning the future than internet clickbait and half-baked punditry, but they risk shredding whatever shared trust we still have left. The suspiciously well-timed bets that one Polymarket user placed right before the capture of Nicolás Maduro may have been just a stroke of phenomenal luck that netted a roughly $400,000 payout.…

> I'm trying to understand what the criticism is here, because the example seems to support the point that these are meant to be a way of learning the future, not oppose it. I thought the whole point was that yes, people with inside knowledge will bet large sums of money on things they expect to happen, and that's what makes the prediction useful. The market is meant to incentivize people who know things to act on them in a way that makes them known.

Except the paragraph you quoted nullify this benefit

> The suspiciously well-timed bets that one Polymarket user placed right before the capture of Nicolás Maduro

So we learnt nothing. For the entire duration the stock is online, its pretty much 50/50 then suddenly 1 day before, the ticker spikes to yes.

Despite looking like a gambling website, the underlying system is a cryptocurrency exchange. With a separate cryptocurrency used as an oracle to decide (yes/no/later) if the yes or no side won. The site itself if pretty hands off with the actual financials. (though, they once did refund people when the oracle system resolved incorrectly)

I don't think this convoluted setup is enough to avoid US gambling laws, but it is important to keep in mind how it actually works.
