I was blown away how easy it was. I placed a bet with real money within 5 minutes of downloading the app.
They allow instant deposits with credit card, and ID verification was real time.
I can’t imagine that the extreme accessibility and the typical dark patterns deployed by every popular app won’t eventually end badly.
(I was also shocked that when looking at my credit card bill online, next to the Kalshi deposit line item it showed a promo “would you like to split this payment over 12 month?” and seemingly was only available for that one transaction. So I could have deposited $1000 via CC into Kalshi and paid it back $83/mo over 12 months.)
This industry is wild.

For example, can someone place a bet on an event that X person will be shot? That question now touches on a whole range of laws regarding murder, life insurance, incitation to violence, free speech? That you just don't touch at all in sports betting.
But if Poly and Kalshi are gambling joints, then of course fixing gambling bets is no no, and that is what actually happens. They ban wins of market predictors who actually correctly predicted something but did it by fixing the game. A market prediction service wouldn't care about that, but gambling joint would.
But ok, let’s follow your thought process. Couldn’t someone place a bet on a sporting event and then murder a key player? Wouldn’t all the same laws be triggered?
Laws against criminal activity aren’t regulations. Regulations are limitations and oversight requirements on business activities.
So, not all that different, but marginally less exploitative. I've never looked at Polymarket but Kalshi and PredictIt slid steadily from things of at least plausible real economic value (a market where it was conceivable [if unlikely] someone would be hedging their insurance contract or something) into total nonsense with no non-gambling function like whether someone would tweet a certain word.
I think prediction markets could serve a similar to a futures markets and have a functional purpose in the economy. It could be useful to generate real time estimates of the probability of some events that no one can control and have real economic consequences, like a hurricane. But evidently that's not where the money is.
Even though nobody can control them, some people can predict them better than others. (Meteorologists with good models and supercomputers, etc.) In general it's impossible to prevent the appearance of insider trading in prediction markets, and it's also impossible -- unless you massively restrict what people can bet on -- to prevent people from doing things for bets to resolve in their favor, which turns those "markets" into "bounties." (The same guys who theorized prediction markets were the ones who theorized assassination markets.)
They're fundamentally broken and the fact that they're allowed is a sign and symptom of a dysfunctional society.
But doesn't Polymarket et al own their own platforms, just like Betfair owns their platform? There is no P2P going on, even if some markets seem to advertise themselves as such so again, seems like the same just minus gambling regulations?
All evidence I’ve seen shows mainstream prediction markets devolve quickly into gambling and related corruption while predicting nothing other than conventional wisdom. especially about real-time facts. The prediction markets on the NBA Finals game four this year were completely useless.
If you want meteorological prediction, you are way better off buying meteorological prediction from a company that sells meteorological predictions.
The most annoying part, somewhat surprisingly, is always with regards to United States KYC restrictions. I've had a fair bit of annoyance trying to move crypto off of services that were once accessible to US customers and no longer are.
This is my biggest takeaway, and I really wonder what payment processor(s) they're using, because the chargeback and fraud rate in filling 'real money' into an online gambling account using visa or mastercard must be through the roof.
Exactly same reason why porn sites use their own specialist payment processors (alluded to in popular fiction in Industry season 4 recently, for instance).
The back end of how they're able to get money "instantly" into peoples accounts must be fascinating, in a how the sausages are made kind of way.
They're called high-risk payment processors and they usually handle all sorts of "legal but sketchy" sectors like porn, gambling, crypto, legalized drugs/vapes, MLMs, etc. It's not even some shadowy darknet industry, if you just search for "high risk payment processor" there is plenty of them which look very professional and even provide official Shopify integrations and stuff.
Interesting that if you go to one of their websites they also handle some pretty normal industries like "furniture" or "travel" just because of the high chargeback rate in them.
The U.K’s highest earner for a few years running was the founder of a U.K. betting site, she had something like a 500 million salary and there is an entire town’s economy supported by her business.
My worry is that social media surveillance could be combined with Polymarket to tailor bets to individuals.
This could be very subtle. You don't really need your punters to always be wrong either. Meaning that sometimes they'd win at the expense of other punters with the illusion they can make money.
You just need them to be wrong, say, 15% of the time and to keep coming back compulsively and consistently over time. The longer the better.
If you're ever around fruit/slot machines you'll notice that they do payout and when they do they make a lot of noise. That hides the fact they slowly cream off a percentage of the money that goes in. In the UK the legal limit is around 30%, keeping it low for new gamblers and ramping up when they're hooked.
With detailed information about punter's lives and no regulation you can weaponise that.
And at that level they're still pocketing hundreds of pounds per week per machine.
The most lucrative ones I've seen (admittedly ~20 years ago now) were being emptied by the operator twice a week and taking out £600-800 every time, per machine, with 3-4 machines per location.
An eye opening industry - I'm sure there are businesses out there that pretend to be one thing (pub, club, etc), but their primary profit source is gambling.
Having worked in such a "business" - the problem is rents. When everyone else around you has a slot machine or two, landlords raise the rents (because they see what their neighbor landlord can get away with). And now, you as a legitimate pub owner have to choose, do you raise the beer prices yet again, or do you put up a slot machine yourself?
And sooner or later, depending on the greediness of the landlord, you have to choose between putting up a slot machine or closing down outright.
Gambling is an incredibly corrosive force. Not just to the gamblers themselves (wtf, I heard there are triple-zero roulette tables in Vegas these days?), but also to everyone and everything surrounding it.
I agree, some level of allowing gambling makes sense, gambling can even be observed in the animal kingdom, but it absolutely needs to be regulated.
I'm guessing that at some point, probably not very long from now, credit cards are going to cut down on this. They don't want to be held responsible for a bunch of debt from gamblers, when they've already paid the sites.
At some point, the fees won't be worth the combination of PR and actually losing money from bankruptcies / delinquencies.
So it's not like people need to go to shady lenders in the first place, they can be pipelined from normal credit card debt into less scrupulous debt collectors.

They accept Visa, Mastercard and Discover via Apple Pay for a 2% deposit fee.
But I also see it says they don’t accept credit card in their help docs. I’m not sure what that’s about.
"Would you like to make decisions that are bad for you?" The future is indeed wild, and personal weakness is for sale. This isn't meant as an attack on you, but a lot of people will not be able to manage this sort of reduced friction. People with MBAs will call this "providing value."
Are you sure those are the correct figures? That's a 4$ win in your favor if you don't use any of the deposited money and cash it back one year later.
I'm not a prediction market user/booster nor a sports gambler, but this is a key difference and a strict improvement from traditional sportsbook apps. If our society is going to have widespread legal gambling, we strongly want it to be parimutuel.
What does make this instance perhaps a bit surprising is that it's Polymarket themselves who are paying those grifters.
They're an incredibly well known US based company targeting US based consumers in a way that is patently illegal. It seems almost unbelievably dumb that they would do this even by the often grotty standards of gambling companies.
They must have realised this would be found out and that, when it was, an investigation and enforcement action would follow? I guess maybe some of the creators will find themselves in hot water as well?
I really don't understand what the long term play is here, other than to be litigated out of business.
