Most uncertain things that people need to hedge (currency, commodity prices) already had a hedge.
In practical terms can someone really give me an example of how they benefited from knowing the future (materially, not emotionally) from a prediction they got from Kalshi? I am honestly curious.
That's way too narrow of the categories. Here are some more cases, and you tell me where can I hedge it? And don't tell me the answer is "go to Goldman Sachs and they create any kind of derivatives to hedge for you", that only works if you are a huge enterprise. I'm talking about SME, or even one person company with $1-5M ARR.
(By the way, I do trade on Polymarket / Kalshi, had a job interview with Kalshi many years ago but did not take their offer since I disagreed a lot with their product design. So all of this is my own opinion).
1. Suppose I run an ice cream shop in midtown Manhattan, and my foot traffic depends on how good the weather is. If it's sunny and dry, I expect a lot of traffic, vice versa, if it's thunderstorm, hurricane or snow, I would run the day without any revenue (and a lot of ice cream waste). What is the way for me to hedge weather risk that could seriously affect my business?
2. Suppose I'm a restaurant owner in Koreatown in LA, and during World Cup I run a restaurant expecting a lot of Korean coming to my area (and my restaurant). So I would ramp up my business, hiring a lot of staffs, sourcing a lot of ingredients from the vendors. Then the biggest risk (and anticipation) is that Korea would be knocked out very early, which unfortunately that precisely happened. So the foot traffic evaporated, and with that the revenue. How could I hedge that risk?
3. Suppose I'm a distributor / reseller who needs to import goods and products from other countries and resells it back to US for profit. Barring the import / export regulations, the biggest risk is tariffs: the orange man can (and did) impose 50% tariffs from China, and all the sudden I face a severe supply-demand imbalance with a lot of contract cancellation and such. How can I hedge such tariff risk from the orange man? (Obviously, the alternative is that I wish we could have elected a more competent leader, but at least 75 million American disagreed with me).
These are not polling places, they are places for capital to influence odds.
Small elections are susceptible to corruption this way, though.
Unfortunately they also place a larger financial inventive on influencing the outcome of future events. Or incentivizing corruption within the inner circles of these events. Because the larger financial upside in these transactions is to bet against what the market thinks, and influence the outcome.
It would be interesting to see how frequently Polymarket predictions bet against the most common prediction and by what margins.
Polymarket projections do not provide investigative insight, as in the Berkshire Hathaway example. It's just gambling. Any influence drawn from these predictions is incidental and reactive, as opposed to active market forces like buying/selling.
I'd be in favor of a prediction market for which which asteroids are likely to collide with something, and when. Though we'll have to shut it down once it becomes feasible that somebody might go up and nudge one.
There is plenty of data that shows they actually don't work very well outside of surfacing insider knowledge (which the commercial prediction markets superficially pretend to be against).
For events where you can't have full picture insider knowledge like elections, prediction markets are pretty awful at accurate predictions.
This is so fallacious. Putting money behind something doesn't make a prediction of a non-knowable more accurate.
Tarot card readings by a psychic must be more accurate predictor than a tarot card reading by an amateur because professional tarot card readers have a financial incentive to be right, so people continue coming back to them for advice. Getting a tarot card reading therefore makes this basically most accurate predictor!!
I mean look at all the oil market manipulation in the Iran war. The pattern was repeated so many times: short oil, announce a ceasefire deal with imminent on Sunday before the markets open, cash out on Monday, rinse and repeat.
The argument is that we get transparency on what's likely to happen. I don't think there's any evidence of this. I've seen any number of very poor predictions coming from Kalshi and Polymarket. I have also seen some clear manipulation.
We should call this what this is: gambling.
Here, let me predict a future where someone will die. On the other side, let me pay for a hit on the same person. /s
^It's a bit extreme and exaggerated, but it's like that on purpose to make a point.
