alt Hacker NewsThese prediction markets shouldn't be allowed for situations where humans can control the outcome.
They do have their place however - one I find particularly interesting is weather prediction markets, primary because they end up having a net benefit. Hundreds are creating their own weather prediction models and are duking it out. Over time these models get better, and the rest of us benefit.
I think these markets could be a net good, but right now they're just enabling insider trading on a scale we've never seen before.

Who is to say if it rained or not? Well now they are a target.
A NY Times reporter was the target of a pressure and threat campaign to change their reporting over whether a rocket in the middle east was intercepted or not before it hit the ground.
Prediction markets are not going to end well full stop IMHO.
Or you could just fund the NOAA instead of making up reasons for more markets.

Can also be used to hedge the risk of rain on the day you've planned an outdoor barbecue!

Humans can, and do, manipulate the weather. There's actually international treaties against doing it.
> Hundreds are creating their own weather prediction models
Weather is chaotic. You don't run a model once and use the result. You run it hundreds of times and average the results. You also need really high quality real time data to be fed into the system to achieve any sort of accuracy, which, is not something any of these hundreds could do on their own.

You can already sell weather predictions. You can just hang a shingle and do it directly. Why do we need a third party gambling apparatus involved?
With enough cash on the line, humans are very resourceful at manipulating outcomes.
Humans already control the weather: https://en.wikipedia.org/wiki/Cloud_seeding.
We already have an example of humans sabotaging the measurement of weather: https://news.ycombinator.com/item?id=41684440. Two ranchers sabotaged weather monitoring stations in order to fraudulently collect millions in drought insurance. One of the farmhands involved ended up dead.
And we have an example of prediction markets attempting to manipulate reporting of events: https://news.ycombinator.com/item?id=47397822.
I have a hard time believing weather prediction markets will be net beneficial. The incentive for sabotage & manipulation up and down the chain seems likely to lead to worse weather predictions overall.
