For many US-based traders, the break with Polymarket did not start as a philosophical choice — it started as an access problem. Polymarket restricts US users and prohibits VPN workarounds in its terms, so a US account built on one carries a standing risk of losing access. When that is weighed against a CFTC-regulated exchange that openly serves US customers, the practical case for switching is straightforward. This page compares the two platforms across regulation, settlement, taxes, liquidity, and market selection.
To be clear about something first: Polymarket is a capable product. The liquidity on major political markets is often better than Kalshi's, and the interface is clean. For traders outside the United States, staying there can be a reasonable choice.
For US residents, the calculus is different. Regulated exchanges exist for a reason, and the difference between a CFTC-designated contract market and an offshore crypto-settled platform becomes concrete the moment access, custody, or enforcement questions arrive.
The trade-off most switchers describe looks like this:
This is not legal advice. But when "slightly better liquidity" is weighed against "possibly having to explain an offshore account to a regulator someday," many US traders find the choice obvious.
The first impression for many switchers is a downgrade. Fewer markets. Wider spreads on some contracts. No crypto settlement, which means funding through a bank transfer rather than a wallet.
The upsides show up quickly, though.
On Polymarket, traders constantly manage 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 holding a US-dollar balance on a CFTC-regulated exchange.
When a position closes on Kalshi, the proceeds are simply USD in the account. Withdrawal goes directly to a bank account. There is no bridging, no swapping, and no gas fees. For anyone trading real capital, that simplicity matters more than people admit.
Kalshi issues US tax forms and reports to the IRS. That sounds like a negative if the goal were opacity, but for traders who want clean records it removes a whole category of work: there is no need to reconstruct wallet-level transaction history across chains at filing time.
Crypto-settled platforms generally leave that reconciliation to the trader. If the records live on-chain, tax season means exporting, labeling, and pricing every trade yourself. With an exchange-issued form in hand, the prediction-market part of a return looks much closer to what a normal preparer already knows how to handle. For a detailed breakdown, see the Kalshi tax hub.
Kalshi's market list has expanded substantially. The categories that draw the most trading 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.
This is not a promotional piece. There are real trade-offs.
Liquidity can be thin outside the headline markets. Spreads on secondary political races can sit wide for days. Building a meaningful position sometimes requires patience or accepting poor fills.
The mobile app is serviceable, but most active trading still happens on desktop.
And the limits on certain contracts are lower than some traders want. Regulatory constraints mean Kalshi can't always offer the position sizes that bigger accounts look for. If you're trying to put six figures into a single market, you might hit caps.
None of these are necessarily dealbreakers. Whether they matter depends on trading style and size.
One thing switchers often miss from the Polymarket ecosystem is the community. Crypto Twitter is noisy, but it is active: people share trades, argue about probabilities, and occasionally surface useful information.
Kalshi's community is smaller but it exists. Kalshi View runs a Telegram channel with source-backed market notes and new-article announcements. It's not a signals service. 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, the case for moving to a regulated alternative is hard to argue against. The risk/reward of circumventing a geofence is hard to justify when a CFTC-regulated exchange 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 US traders switch away from Polymarket, which restricts 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; for US tax reporting it is simpler.
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. It's worth watching a few markets before committing real money, just to understand how pricing moves.
