Last February, I was sitting in my apartment watching a position on Polymarket that I couldn't close. The geofence had finally caught up with me. I'd been using a VPN for months, telling myself the CFTC wouldn't actually care about some guy in Chicago trading election contracts. Then one morning the site just wouldn't load my wallet. Three thousand dollars in USDC, stuck in limbo while I figured out how to extract it through a friend's non-US wallet. That was the week I moved everything to Kalshi.
Let me be clear about something. Polymarket is a good product. The liquidity on major political markets is often better than Kalshi's. The interface is clean. If I lived in Portugal or Singapore, I'd probably still trade there.
But I don't. I live in Chicago. I spent three years on a CME equity-index futures desk before going independent. I know what regulated markets look like, and I know what happens when US regulators decide to make an example of someone.
The calculus was simple:
I'm not a lawyer. I'm not giving legal advice. But when I weighed "slightly better liquidity" against "possibly having to explain this to a regulator someday," the choice became obvious.
The first week on Kalshi felt like a downgrade, honestly. Fewer markets. Wider spreads on some contracts. No crypto settlement, which meant I had to actually wire USD like it was 2015.
Then I started noticing the upsides.
On Polymarket, you're constantly managing two risks: the position itself and the USDC peg. Yes, USDC is stable. Yes, it's probably fine. But "probably fine" is not the same as "dollars in a regulated account."
When I close a position on Kalshi, the money is just there. I can withdraw it to my bank account. I don't have to bridge anything, swap anything, or pay gas fees. For someone trading their own capital, this matters more than people admit.
Kalshi sends 1099s. They report to the IRS. This sounds like a negative if you're trying to hide income, but I'm not. I want clean records. I want to file my taxes without hiring a crypto accountant to trace wallet transactions across three chains.
My CPA had never heard of prediction markets before I showed him my Kalshi 1099. He looked at it, said "oh, this is just like futures," and moved on. That conversation with Polymarket records would have taken two hours.
Kalshi has expanded a lot since I joined. The markets that get most of my attention:
You can browse the full list at kalshi.com. Not everything is liquid enough to trade actively, but the core political and economic markets usually have decent two-way flow.
I'm not here to shill. There are real problems.
Liquidity can be thin outside the headline markets. I've watched spreads on secondary political races sit at 10+ cents for days. If you're trying to build a meaningful position, you sometimes have to be patient or accept bad fills.
The mobile app is fine but not great. I do most of my trading on desktop.
And the limits on certain contracts are lower than I'd like. Regulatory constraints mean Kalshi can't always offer the position sizes that bigger traders want. If you're trying to put six figures into a single market, you might hit caps.
None of these are dealbreakers for me. They might be for you.
One thing I missed from the Polymarket ecosystem was the community. Crypto Twitter is annoying, but it's active. People share trades, argue about probabilities, occasionally surface useful information.
Kalshi's community is smaller but it exists. I run a Telegram channel where I post market observations and trade ideas. It's not a signals service. I'm wrong plenty. But if you want to talk through contract pricing with people who actually trade, it's a decent place to start.
If you're a US-based trader using Polymarket through a VPN, I think you should seriously consider why I quit Polymarket for Kalshi. The risk/reward of circumventing a geofence is hard to justify when a regulated alternative exists.
If you're outside the US, the calculus is different. Polymarket's liquidity advantages might outweigh Kalshi's regulatory clarity for you.
And if you're new to prediction markets entirely, starting on Kalshi makes sense. The KYC is annoying but it's a one-time thing. You'll learn the mechanics on a platform you can actually use legally, with money you can withdraw cleanly.
Yes. Kalshi is a CFTC-regulated exchange, which means US residents can legally trade on the platform. You'll need to complete KYC verification with a US ID and link a bank account for deposits and withdrawals. This is one of the main reasons I switched from Polymarket, which explicitly prohibits US users.
No. Kalshi operates in USD only. You deposit via bank transfer (ACH or wire) and withdraw the same way. There's no USDC, no wallet connection, no blockchain involvement. Some people see this as a limitation. I see it as simpler, especially for tax purposes.
On major political markets, Polymarket often has tighter spreads and more volume. But liquidity varies by contract and time period. Kalshi's economic markets (Fed decisions, CPI, employment) are sometimes better. If you're US-based, the liquidity comparison is moot anyway since Polymarket isn't a legal option.
Create an account at kalshi.com, complete the identity verification (takes a day or two), and fund via bank transfer. Start small. The minimum trade is usually around a dollar per contract. I'd recommend watching a few markets before putting real money in, just to understand how pricing moves.
Not financial advice. I trade my own money and you can lose yours. Do your own research.
