How Kalshi vs Polymarket compare at a glance
Kalshi and Polymarket are both prediction markets worth joining.
What are prediction markets? These are trading options, loosely similar to stock market options, that let you predict the outcome of real-world events. However, there are a few differences you’ll find on the different sites that offer prediction markets.
Are prediction markets legal? Yes. Kalshi is a CFTC-regulated entity that operates in 44 US states. That means all of its operations are centralized and comply with strict rules set by the CFTC, which instills trader confidence. Polymarket just received approval to relaunch in the US after acquiring QCEX, a CFTC-licensed exchange. It was previously outlawed in the country after it was accused of operating without approval.
What shapes user preferences
When picking between Kalshi and Polymarket, traders have different motivations. Unlike Kalshi, Polymarket doesn’t offer responsible trading tools, which can alienate some users. It doesn’t set limits for deposits or predictions. High rollers will obviously appreciate the uncapped limits, but this can pose a challenge for undisciplined traders.
How regulation shapes user access
The CFTC, which oversees Kalshi’s operation, helps foster trader confidence because the rules of engagement are clear. For instance, Kalshi must verify all of its users and set prediction limits for each market. This assures users that their transactions are safe. Polymarket’s decentralized approach means its user transactions and general operations aren’t regulated by a single entity. This can be both good and bad. Good in the sense that transaction settlements are quicker and anonymous. But this can be a concern because a lack of stringent verification can compromise trader safety.
Trading fees and structural costs
Polymarket doesn’t charge traders for deposits or trading fees. However, users may incur network or third-party fees when using exchanges. As outlined in our
Kalshi review, the site imposes transaction fees ranging from 2$ to 4%, depending on the size of the event contract.
User interface and learning curve
Navigating the Kalshi website is simple. Traders can clearly see the liquidity for each market. Moreover, each market has a graph displaying ongoing activity, trends, and potential payout when the contract finalizes. This makes it highly intuitive for users. Polymarket’s UI is equally intuitive, with some users reporting that the app performs faster than Kalshi. When comparing
Kalshi vs Robinhood, the latter also comes out on top.
