Reminds me of when I made about $40k finding a source that had CO2 data in close to real time when other people were tracking one about 12 hours delayed See https://misinfounderload.substack.com/p/tales-from-predictio...

Those are great stories in the article!

What do you think taxiways are made of? Or parking lots?

Just wait until they start killing people to win bets. It's going to happen. It'll happy by proxy too. When they figure 90% of Tesla's or SpaceX's valuation is tied to Elon, suddenly he becomes your mark.

In a sense, that's already happened. https://www.reuters.com/world/middle-east/kalshi-sued-over-o... and https://www.theguardian.com/world/2026/apr/18/iran-war-bets-... > Later, a single user would make over $550,000 after betting that Ayatollah Ali Khamenei would topple, just moments before his assassination by Israeli forces.

It hasn't happened in this case. Your example has causality reversed. Khamenei wasn't killed because there was a prediction market about the political leadership of Iran.

Betting against what is widely considered as “expected”, “reasonable” is such a major source of profit when one can influence the income. Whether it’s a temperature sensor one can breathe on or movement of troops one can control or influence[0], the idea is the same—except in one of the above you can add “death and suffering” in addition to some unfortunate gamblers losing their money.

A depressing thought: it will only tip in favor of common good when the probability of something that we today consider “normal” becomes so small that betting on that finally becomes profitable to insiders with influence. Imagine that world…

[0] No, I’m not going to change my writing style because it is considered a “tell” of LLM use.

I agree, but the fact that authorities even have to spend time investigating is a massive negative externality. A few years years ago, there was no conceivable profit motive for interfering with weather sensors on public property. Now there is one.

This is the definitive argument for me against prediction markets. It creates incentives to do really dumb shit.

Yep. Feels like we see new depressingly creative examples of this every few days.

Between this and crypto cryptocurrencies (which obviously can be used to make bets) I don’t know which is more destructive to society

How is it even remotely as destructive as casinos, where the odds are always against you? From a probability perspective Polymarket is much more fair, as you actually have positive expected value if you have an information advantage.

The ingredient you are missing is fraud

This hypothetical situation had existed since the dawn of capital markets, or at least since the dawn of short selling. I don’t think we’ve ever seen anyone get assassinated to make a short bet pay off though.

Fiat money is obviously more destructive, but you'd have to do some basic research to figure that out.

Here's a thought experiment for you: if "fiat currency=bad" and "hard money=good", why did the world collectively switch? Where are all the prosperous societies that held the line?
