I finally gave in to my curiosity and downloaded Kalshi last week to place a few bets on the World Cup.

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.

> They allow instant deposits with credit card

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.

Well try to make a withdrawal and see how convinient that might be. Internet casinos are usually easy to get money into but hard to get money out of.

Instant deposit via credit card? Is that not considered a cash advance?

This was my experience trying out "traditional betting" for the first time with Betfair last Worldcup, and some other platform I tried out before as well. Not sure what Kalshi/others are doing that is so different?

I read a book this year about sports gambling in the US [1], and it points out how nasty and predatory it is. I think "prediction markets" have even less regulation? I would talk to my sports fan buddies at work and they would say "oh, just how sportsbooks in Vegas operate already", but this is on-demand, in your face, constantly nudging you to bet with dark patterns and "comps". I used to want sports gambling legal in the US, but the way it has gone is incredibly disgusting and is starting to make watching sports almost annoying. The crawl on the bottom is no longer scores, but moneylines...

The on-ramp in crypto is incredibly well built out. But then, once you are in the fake money world, you will notice that the off-ramp doesn't exist.

You think that's wild, look into prop firms some time

Let's compare and contrast this to how credit card companies treat sexual content vendors. Remember when a raft of games got delisted on Steam because of pressure from cc companies?

The U.S. is quite far behind the rest of the world on sports betting, which means you don’t even need to imagine, we know from other countries that it doesn’t end well. The most worrying aspect is, the current U.S. government has no interest in the regulations that have helped minimise the problems in other countries.

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.

Yeah, and also inevitable that a product designed to so efficiently separate people from their money would be overrun by grifters and scammers from the influencer/creator world.

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.

Back in the good old days you needed a few more steps before you got into debt after gambling.

How were you able to use a credit card when it's not a payment they accept?
